The best peace lily fertilizers support steady leaf growth without making feeding harder than it needs to be. My best overall pick is GARDENWISE Peace Lily Liquid Fertilizer, whose 3-1-2 formula is tailored to peace lilies; Miracle-Gro Indoor Plant Food is a straightforward choice for general houseplant feeding, while Gardenera Organic Liquid Kelp Fertilizer suits buyers seeking a kelp-based option. The main tradeoffs are concentrated liquids that need measuring, ready-to-use sprays that may be less convenient for feeding through the soil, and broader formulas that can serve several plants but are less peace-lily-specific. I compare all 15 picks by formula, application, and ease of use. Read on for the full breakdown and guidance on choosing a fertilizer that fits your plant-care routine.

Key Takeaways
- Peace-lily-specific 3-1-2 liquids stand out for buyers who want a formula aimed at this plant; GARDENWISE, FOLLOWIN, and Gardenera offer that stated balance in different bottle sizes and formats.
- General indoor-plant foods trade specificity for flexibility. Miracle-Gro Indoor Plant Food and Cute Farms make more sense when one fertilizer needs to serve several kinds of houseplants.
- Bottle size and concentration affect routine more than headline claims. A larger bottle may suit a collection, while a concentrate can reduce storage needs but calls for careful measuring and dilution.
- Sprays offer a different application method, not an automatic substitute for root feeding. Compare spray options with liquid fertilizers based on how you prefer to apply nutrients and follow each label.
- The lineup includes distinct ingredient and format choices. Organic liquids, kelp-based products, conventional feeds, concentrates, and sprays suit different preferences, so there is no single format that fits every owner.

More Details on Our Top Picks
Houseplant Resource Center Indoor Plant Food, Organic Liquid Fertilizer, 8 oz
For a peace lily owner who also tends pothos, monstera, or other indoor plants, this urea-free 3-1-2 formula is a flexible alternative to products made just for Spathiphyllum, such as GARDENWISE Peace Lily Liquid Fertilizer. Its balanced ratio and chelated micronutrients are intended to support foliage and roots, while the gentle formula suits a range of houseplants with different needs. The 8-ounce bottle is a modest supply, though, and you must dilute it before watering or spraying; it is less convenient than a ready-to-use product. I’d choose it for a shared plant-care routine, not for someone seeking the largest concentrate or a formula tailored exclusively to peace lilies. Compared with FOLLOWIN’s larger bottle and measuring cap, this is the more compact, general-purpose pick.
Pros:- 3-1-2 ratio with chelated micronutrients supports foliage and root development
- Urea-free formula is designed with sensitive roots in mind
- Suitable for a broad range of houseplants, not only peace lilies
- Can be applied with a watering can or spray bottle
Cons:- Requires dilution before every application
- The 8-ounce bottle offers less volume than FOLLOWIN’s 21-ounce option
- General-purpose formulation is less specifically tailored to peace lilies than GARDENWISE or HiThrive
Best for: Houseplant owners who want one gentle fertilizer for a peace lily plus other indoor plants such as pothos and monstera.
Not ideal for: People who want a peace-lily-only formula, a ready-to-use feed, or a larger bottle for frequent fertilizing.
- Brand:Houseplant Resource Center
- Form:Liquid
- NPK ratio:3-1-2
- Volume:8 fluid ounces
- Application:Dilute and apply with a watering can or spray bottle
- Formula:Urea-free with chelated micronutrients
- Made in:USA
Our verdict“Choose this compact, gentle concentrate if you want to feed a peace lily and several other houseplants with one formula.”
GARDENWISE Peace Lily Liquid Fertilizer, 3-1-2, 8 fl oz
GARDENWISE makes the most sense when the peace lily is the clear priority: it pairs a 3-1-2 ratio with essential micronutrients and is formulated specifically for Spathiphyllum. Its stated 1:128 dilution gives a concrete mixing guide for routine feeding, and the concentrate can be used for watering or foliar application. That focus is also its main limitation. Houseplant Resource Center’s indoor plant food is designed for a much broader mix of species, so it is a better fit if one bottle needs to serve a whole collection. At 8 ounces, GARDENWISE is also smaller than HiThrive’s 16-ounce bottle. I’d pick this for a peace-lily-led routine where clear species targeting matters more than versatility or a larger supply.
Pros:- Formulated specifically for peace lilies
- 3-1-2 nutrient ratio includes essential micronutrients
- 1:128 dilution instructions give a defined mixing guide
- Can be applied through watering or foliar application
Cons:- Its peace-lily focus makes it less suitable as a single fertilizer for varied houseplants
- Must be diluted before use
- The 8-ounce bottle is smaller than HiThrive’s 16-ounce option
Best for: Peace lily owners who want a species-targeted concentrate with a stated dilution ratio and the option of soil or foliar application.
Not ideal for: People feeding a varied houseplant collection or looking for a larger bottle to reduce replenishment.
- Brand:GARDENWISE
- Form:Liquid concentrate
- Fertilizer ratio:3-1-2
- Volume:8 fluid ounces
- Dilution ratio:1:128
- Target plant:Peace lilies (Spathiphyllum)
- Application:Watering or foliar application
Our verdict“Choose GARDENWISE if your feeding routine centers on peace lilies and you value a defined dilution guide over broad plant coverage.”
GrowThrive Organic Peace Lily Liquid Fertilizer, 10 oz
GrowThrive stands apart from the nutrient-ratio-focused options with a multi-strain microbial formula reporting over 5.9 billion CFUs per fluid ounce. That makes it a distinct choice for peace lily owners interested in root-supporting microbes alongside their feeding routine, rather than a conventional 3-1-2 listing like GARDENWISE or FOLLOWIN. It is made for standard, miniature, and giant peace lilies, and the 1:400 dilution means the 10-ounce bottle is mixed into a large volume of water when used as directed. The tradeoff is less clarity at measuring time: the cap holds about 1.7 fluid ounces but has no graduated markings. Like the other concentrates here, it also requires mixing before application. I’d choose it for its microbial approach, not for the simplest dosing process.
Pros:- Multi-strain formula reports over 5.9 billion CFUs per fluid ounce
- Designed for standard, miniature, and giant peace lily varieties
- 1:400 mixing ratio makes the concentrate suitable for preparing diluted feed
- Includes a cap for measuring the concentrate
Cons:- Must be diluted before applying to soil
- Measuring cap has no graduated markings
- Microbial approach is less directly comparable to the stated 3-1-2 ratios of GARDENWISE and FOLLOWIN
Best for: Peace lily growers who want a microbial formula for root-focused care across standard, miniature, or giant varieties.
Not ideal for: Buyers who prefer a clearly marked measuring cap, a simple nutrient-ratio comparison, or a ready-to-use fertilizer.
- Brand:GrowThrive
- Form:Liquid concentrate
- Volume:300 ml (10 oz)
- Mixing ratio:1:400
- Application:Dilute with water and apply to soil
- Target plants:All peace lily varieties
- Bacterial count:Over 5.9 billion CFUs per fluid ounce
- Pack size:1
Our verdict“Pick GrowThrive if microbial support is your priority and you are comfortable measuring concentrate without marked graduations.”
HiThrive Peace Lily Liquid Fertilizer, 16 oz
For several peace lilies or regular feeding across a larger collection, HiThrive’s 16-ounce bottle offers more concentrate than GARDENWISE’s 8-ounce format and is stated to make up to 96 gallons when diluted as directed. Its listed nutrients include nitrogen, phosphorus, and potassium plus calcium, magnesium, and zinc, giving buyers more detail about the nutrient set than some competitors provide. It is also formulated specifically for peace lilies and allows soil application or bottom watering, which may suit growers who prefer watering from below. The compromise is that it is not positioned as a general-purpose houseplant feed, unlike Houseplant Resource Center’s option, and it still needs dilution. The listed 1:10 mixing ratio should be followed with the product directions, rather than relying on bottle volume alone.
Pros:- 16-ounce bottle is larger than the 8-ounce GARDENWISE and Houseplant Resource Center options
- Stated yield is up to 96 gallons when mixed as directed
- Includes listed macro- and micronutrients, including calcium, magnesium, and zinc
- Can be applied to soil or by bottom watering
Cons:- Must be diluted before use
- Formulated specifically for peace lilies rather than a broad range of houseplants
- The stated 1:10 mixing ratio means buyers need to follow the product directions carefully
Best for: Growers with multiple peace lilies who want a larger species-specific bottle and the option to bottom-water.
Not ideal for: Owners seeking one fertilizer for a mixed houseplant collection or anyone who wants ready-to-use feeding.
- Brand:HiThrive
- Form:Liquid
- Volume:16 fluid ounces
- Stated coverage:Makes up to 96 gallons
- Mixing ratio:1:10
- Target plant:Peace lily
- Key nutrients:Nitrogen, phosphorus, potassium, calcium, magnesium, and zinc
- Application:Soil application or bottom watering
Our verdict“Choose HiThrive for a larger peace-lily-specific supply if you value bottom-watering flexibility over use across a mixed plant collection.”
FOLLOWIN Peace Lily Liquid Fertilizer, 3-1-2 NPK, 21 fl oz
FOLLOWIN combines a 21-ounce bottle with a 3-1-2 NPK blend and EDTA-chelated micronutrients, making it the most flexible choice here for someone feeding peace lilies alongside other houseplants. Its listed targets extend beyond peace lilies, unlike the dedicated GARDENWISE and HiThrive formulas, and the measuring cap gives a repeatable dosing method: one 10 ml cap per 0.8 gallon of water. The nutrient list is notably broad, including calcium, magnesium, iron, zinc, copper, manganese, and boron. Its stated yield is up to 48 gallons, less than HiThrive’s listed 96 gallons, despite the larger bottle; buyers should compare the provided mixing directions rather than assume volume alone predicts coverage. Dilution is still required, so it is not the simplest option for occasional feeding.
Pros:- 3-1-2 NPK blend is suited to foliage-focused houseplant feeding
- EDTA-chelated micronutrients include calcium, magnesium, iron, zinc, copper, manganese, and boron
- 21-ounce bottle is the largest listed by volume among these five products
- Measuring cap supports a defined mixing routine
Cons:- Requires dilution before application
- Stated yield of up to 48 gallons is lower than HiThrive’s listed 96-gallon coverage
- Broader houseplant targeting is less peace-lily-specific than GARDENWISE or HiThrive
Best for: Houseplant owners who feed peace lilies and other indoor plants and want a larger bottle with a defined cap-based mixing instruction.
Not ideal for: People who want a peace-lily-only formulation, ready-to-use fertilizer, or the highest stated diluted coverage in this group.
- Brand:FOLLOWIN
- Form:Liquid
- NPK ratio:3-1-2
- Volume:21 fluid ounces
- Mixing instruction:1 cap (10 ml) per 0.8 gallon of water
- Stated yield:Up to 48 gallons when diluted as directed
- Target plants:Houseplants, including peace lilies
- Micronutrients:EDTA-chelated calcium, magnesium, iron, zinc, copper, manganese, and boron
Our verdict“Choose FOLLOWIN if you want one measured 3-1-2 concentrate for peace lilies and a wider indoor plant collection.”
Miracle-Gro Indoor Plant Food, Liquid, 8 oz Bottles, 2-Pack
Broad indoor-plant compatibility makes this a practical choice if your peace lily shares a shelf with other houseplants, herbs, or vegetables. Unlike Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, which is tailored to peace lilies, this Miracle-Gro formula is positioned for a wider range of indoor plants. You can apply it directly to soil or mix four pumps into a quart of water, giving you some flexibility at feeding time. The two-bottle pack supplies 16 fl oz total, a useful reserve for regular care. The tradeoff is its weekly schedule: it asks for more frequent attention than a less routine-driven feeding approach, and the product is intended for indoor containers. Choose it for a mixed collection, not if your priority is a formula specifically designed around peace lilies.
Pros:- Suitable for peace lilies and a broad range of indoor plants
- Can be applied directly to soil or mixed with water
- Two 8 fl oz bottles provide 16 fl oz total
- Product information describes it as feeding plants instantly
Cons:- Recommended for weekly use, which can add to routine upkeep
- Intended for indoor container plants rather than broader garden use
Best for: Houseplant owners who want one liquid feed for peace lilies alongside other indoor plants, flowers, herbs, or vegetables.
Not ideal for: Peace-lily-only growers seeking a plant-specific formula or buyers who prefer not to follow a weekly feeding schedule.
- Brand:Miracle-Gro
- Form:Liquid
- Bottle size:8 fl oz
- Pack quantity:2
- Total volume:16 fl oz
- Application frequency:Once a week
- Mixing instruction:4 pumps in 1 quart of water, or apply directly to soil
- Suitable plants:Indoor plants, including peace lilies, flowers, vegetables, and herbs
Our verdict“Choose this two-bottle option if you want a flexible feed for a mixed indoor collection rather than a peace-lily-specific formula.”
Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, 3-1-2, 8 fl oz
Leaves and Soul is the most straightforward pick here for buyers who want a peace-lily-targeted concentrate with its nutrient ratio clearly stated. Its 3-1-2 formula gives more information about the blend than the TPS Nutrients Peace Lily Fertilizer Spray, whose supplied details focus on mist application rather than a formula ratio. Because this is a concentrate, the 8 fl oz bottle is mixed with water before use, making it suited to growers comfortable measuring and preparing feed. That extra step is also the main drawback: it is less grab-and-use than the spray, and the supplied product details do not state a feeding schedule or expected solution yield. The USA-made label may appeal to shoppers who value that origin detail, but it does not replace the need to follow the product’s dilution directions.
Pros:- 3-1-2 formula is stated on the product
- Designed for peace lilies and other indoor plants
- Concentrated liquid is mixed with water for application
- Made in the USA
Cons:- Requires dilution before use
- Supplied details do not specify a feeding frequency
- Supplied details do not state how much finished solution the bottle makes
Best for: Peace lily owners who prefer a labeled 3-1-2 concentrate and are comfortable diluting fertilizer before feeding.
Not ideal for: Beginners seeking a ready-to-use spray or buyers who need clearly stated coverage and feeding-frequency details before purchase.
- Brand:Leaves and Soul
- Formula:3-1-2
- Form:Liquid concentrate
- Liquid volume:8 fl oz
- Mixing ratio:1:4
- Target species:Peace lily
- Made in:USA
Our verdict“Pick this if a stated 3-1-2 ratio and peace-lily focus matter more to you than ready-to-use convenience.”
Miracle-Gro Tropical Houseplant Food, Liquid Fertilizer, 8 fl oz, 2-Pack
This Miracle-Gro option suits peace lilies kept among other tropical foliage plants. Its stated micronutrients—magnesium, manganese, copper, iron, and zinc—set it apart from the broader Miracle-Gro Indoor Plant Food, which is described for a wider mix of houseplants, flowers, vegetables, and herbs. That makes the tropical version a more focused fit for collections that also include pothos, monstera, or croton. The two 8 fl oz bottles offer a combined 16 fl oz supply, while the recommended weekly use during spring and summer gives the routine a defined seasonal window. The limitation is that this schedule is both frequent and season-specific; the supplied details do not outline feeding outside spring and summer. Skip it if you want a peace-lily-only product or a year-round schedule spelled out on the listing.
Pros:- Contains five listed micronutrients
- Suitable for peace lilies and a range of tropical houseplants
- Two 8 fl oz bottles provide 16 fl oz total
- Product information says it starts feeding instantly
Cons:- Recommended for weekly application during spring and summer
- Supplied details do not give a feeding schedule for other seasons
- Less tailored to peace lilies than Leaves and Soul Peace Lily Liquid Fertilizer Concentrate
Best for: Growers with peace lilies and a collection of tropical foliage plants who feed regularly during spring and summer.
Not ideal for: Owners seeking a peace-lily-specific fertilizer or clear directions for feeding through every season.
- Type:Liquid fertilizer
- Volume per bottle:8 fl oz
- Pack size:2
- Micronutrients:Magnesium, manganese, copper, iron, and zinc
- Application frequency:Once per week
- Recommended season:Spring and summer
- Suitable plants:Tropical houseplants, including spider plants, ZZ plants, snake plants, croton, pothos, monstera, and fiddle-leaf figs
Our verdict“Choose this for a tropical-plant collection you feed weekly in the warmer growing seasons, not for a peace-lily-only routine.”
Peace Lily Fertilizer Spray, 16 fl oz
For someone who wants to avoid measuring concentrate, this 16 fl oz peace lily spray offers the simplest application method in this group. It is designed for indoor peace lilies and delivers nutrients as a mist, unlike Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, which requires mixing with water. That convenience comes with less detail: the supplied information gives no coverage estimate, dilution guidance, or application frequency, so buyers have fewer instructions to plan around. Its peace-lily focus is another clear boundary. Miracle-Gro Indoor Plant Food is a better fit if one product needs to serve a varied indoor collection, while this spray makes more sense for a grower who wants a product aimed specifically at peace lilies. I would favor it for easy application, not for detailed feeding guidance.
Pros:- Spray application avoids mixing a concentrate
- Designed specifically for indoor peace lilies
- 16 fl oz bottle provides a ready-to-use format
- Product description links regular use with foliage, plant vitality, and flowering
Cons:- No coverage estimate or dilution details are supplied
- No application frequency is stated in the supplied information
- Peace-lily-specific focus offers less flexibility for mixed plant collections
Best for: Peace lily owners who want a ready-to-apply mist and do not need one fertilizer to serve several plant types.
Not ideal for: Buyers who want a stated dilution ratio, coverage estimate, or feeding schedule, or who need fertilizer for multiple kinds of plants.
- Brand:TPS Nutrients
- Form:Liquid
- Application method:Spray
- Target species:Peace lilies
- Volume:16 fl oz
- Number of items:1
- Made in:USA
Our verdict“Pick this spray if quick, peace-lily-focused application matters more than detailed feeding directions or multi-plant versatility.”
Gardenera Organic Liquid Kelp Fertilizer for Peace Lilies, 8 fl oz
Gardenera stands out for its Ascophyllum nodosum kelp base and unusually high stated yield: the 8 fl oz concentrate makes up to 45 gallons of nutrient solution. That makes it a different proposition from the ready-to-use Peace Lily Fertilizer Spray, which avoids mixing but does not provide a coverage figure in the supplied details. Gardenera is formulated for peace lilies and other Spathiphyllum varieties, with the description linking it to foliage, roots, and blooms; its stated use for indoor and outdoor peace lilies also gives it a broader setting than indoor-only choices. The tradeoff is narrow plant appeal and the extra work of using a concentrate. The supplied details do not provide a dilution ratio or feeding schedule, so buyers wanting exact routine instructions may prefer the Leaves and Soul 3-1-2 concentrate instead.
Pros:- Made with Ascophyllum nodosum seaweed
- 8 fl oz concentrate makes up to 45 gallons of solution
- Formulated for peace lilies and other Spathiphyllum varieties
- Described for indoor and outdoor peace lilies
Cons:- Peace-lily focus may limit usefulness across a mixed plant collection
- Concentrate requires preparation before application
- Supplied details do not specify a mixing ratio or feeding frequency
Best for: Peace lily growers who want a kelp-based concentrate with a stated high solution yield for indoor or outdoor plants.
Not ideal for: Mixed-houseplant owners seeking a broadly suitable fertilizer or buyers who need a stated mixing ratio and feeding schedule.
- Brand:Gardenera
- Product type:Organic liquid kelp fertilizer concentrate
- Plant type:Peace lily (Spathiphyllum)
- Ingredient:Ascophyllum nodosum seaweed
- Volume:8 fl oz
- Yield:Makes up to 45 gallons
- Number of items:1
- Made in:USA
Our verdict“Choose Gardenera if you want a kelp-based concentrate for peace lilies and value its stated solution yield over ready-to-use convenience.”
Gardenera Plant Superfood Spray for Peace Lilies, 8 oz
Gardenera Plant Superfood Spray is the pick for peace lily owners who prefer a leaf-and-stem spray over a fertilizer they have to mix into watering water. Its formula lists vitamin B-1, glucose, iron, manganese, and zinc, giving it a micronutrient focus that differs from the stated 3-1-2 blends in the Gardenera Liquid Peace Lily Fertilizer Concentrate and TPS Nutrients Peace Lily Liquid Fertilizer. The spray format also makes it easy to add to a weekly plant-care routine, and the product is suitable for indoor and outdoor plants. The tradeoff is limited application guidance: the description gives no dilution instructions, and weekly spraying takes more repeated attention than a concentrate mixed when watering. I’d choose it for convenience and foliage application, not when I want a clearly specified NPK feeding plan.
Pros:- Spray format can be applied directly to leaves and stems
- Lists vitamin B-1, glucose, iron, manganese, and zinc
- Suitable for indoor and outdoor plants
- Can be used year-round
Cons:- Weekly application requires a regular routine
- No dilution instructions are provided
- Does not state an NPK ratio
Best for: Peace lily owners who want a ready-to-apply leaf-and-stem spray with listed micronutrients and are comfortable following a weekly routine.
Not ideal for: Growers who want a stated NPK ratio, dilution directions, or fewer recurring applications; the description does not provide mixing guidance.
- Brand:Gardenera
- Model number:PSF-SPRAY-PEACE-LILY-8oz
- Volume:8 fluid ounces
- Form:Spray
- Use:Indoor and outdoor plants
- Recommended frequency:Weekly
- Key ingredients:Vitamin B-1, glucose, iron, manganese, and zinc
Our verdict“Choose this spray if you value direct foliage application and listed micronutrients more than a specified NPK ratio or a less frequent feeding routine.”
Cute Farms Organic Liquid Plant Food for Houseplants, 8 fl oz
Cute Farms Organic Liquid Plant Food suits peace lily owners who already feed several indoor plants and want one gentle formula for their collection. The urea-free, vegan formula is described as suitable for use with every watering, while the pump gives a measured dose: seven pumps per 16 ounces of water. That makes its routine more explicit than the Gardenera Plant Superfood Spray, which recommends weekly use but provides no dilution directions. The tradeoff is that this is a general indoor-houseplant food, not a peace-lily-specific formula like Gardenera’s 3-1-2 concentrate or TPS Nutrients’ liquid fertilizer. It also must be diluted before use, so it is less convenient than a ready-to-use mist. I’d favor it when repeatable dosing across houseplants matters more than a specialized peace lily formula.
Pros:- Organic, urea-free, and vegan formula
- Pump dispenser helps measure the dose and has a locking system
- Stated mixing ratio of seven pumps per 16 ounces of water
- Described as gentle enough for use with every watering
Cons:- Requires dilution before application
- Formulated for indoor houseplants rather than specifically for peace lilies
- Every-watering use calls for consistent attention to the feeding routine
Best for: Indoor plant owners who feed a mix of houseplants regularly and want a pump-dosed, urea-free formula with a stated mixing ratio.
Not ideal for: Peace lily growers seeking a plant-specific formula or anyone who wants fertilizer that can be applied without measuring and diluting.
- Brand:Cute Farms
- Form:Liquid
- Volume:8 fluid ounces
- Weight:9.6 ounces
- Target species:Indoor houseplants
- Use:Plant growth and root development
- Mixing ratio:7 pumps per 16 ounces of water
- Ingredients:Organic, urea-free, and vegan
- Made in:United States
Our verdict“Pick Cute Farms if you want a measured, repeat-use food for a broader indoor plant collection rather than a peace-lily-specific fertilizer.”
Gardenera Liquid Peace Lily Fertilizer Concentrate, 3-1-2, 8 fl oz
Gardenera Liquid Peace Lily Fertilizer Concentrate is the most direct fit here for buyers who want a named peace lily formula and a defined feeding mix. Its 3-1-2 ratio and instruction to mix one teaspoon per gallon make preparation more specific than the TPS Nutrients Peace Lily Liquid Fertilizer description, which provides the same ratio but no mixing amount in the supplied details. Compared with Gardenera’s ready-to-use Peace Lily Spray Fertilizer Mist, this concentrate requires more preparation but lets the buyer make a diluted batch for watering. The product is described as organic and claims to support growth, flowering, and root strength; those benefits are claims in the provided product data, not independently verified evidence. I’d rank it ahead of general-purpose foods for buyers prioritizing a peace-lily-specific formula, with dilution as the main inconvenience.
Pros:- Formulated specifically for peace lilies
- Stated 3-1-2 fertilizer ratio
- Clear mixing instruction of one teaspoon per gallon of water
- Described as 100% organic
Cons:- Requires measuring and dilution before use
- Growth, flowering, and root benefits are product claims not independently verified in the supplied information
- Less convenient for quick application than Gardenera’s ready-to-use spray mist
Best for: Peace lily owners who want a plant-specific 3-1-2 concentrate and are willing to measure and dilute fertilizer before watering.
Not ideal for: Buyers who want a ready-to-use spray or who prefer product claims supported by more detail than the description provides.
- Brand:Gardenera
- Formula:3-1-2
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Target plant:Peace lily
- Mixing ratio:1 teaspoon per gallon of water
- Pack count:1
- Description:Described as an organic plant food
Our verdict“Choose this concentrate if a peace-lily-specific 3-1-2 formula and a clear mixing ratio matter more to you than ready-to-use convenience.”
Gardenera Peace Lily Spray Fertilizer Mist, 3-1-2, 8 oz
Gardenera Peace Lily Spray Fertilizer Mist is the convenient choice for buyers who want a peace-lily-specific product without mixing a concentrate. It arrives as a ready-to-use 3-1-2 mist, unlike Gardenera Liquid Peace Lily Fertilizer Concentrate, which requires one teaspoon per gallon of water. That removes measuring from the routine, though the product still calls for weekly or watering-time use and care not to overwater. The listed uses include foliage, blooms, and root growth, but the description does not give an exact spray quantity or a more detailed schedule. Its narrow target is useful if you only want a peace lily product; it is less flexible than Cute Farms Organic Liquid Plant Food, which is described for indoor houseplants generally. I’d pick this for ease and plant-specific labeling, not for a multi-plant fertilizer shelf.
Pros:- Ready-to-use spray bottle requires no dilution
- Formulated specifically for peace lilies
- Lists a 3-1-2 NPK ratio
- Can be used indoors or outdoors
Cons:- Intended for peace lilies rather than general-purpose houseplant use
- Requires care to avoid overwatering
- Description does not specify an exact spray dose
Best for: Peace lily owners who want a pre-mixed, plant-specific fertilizer mist and prefer spraying to preparing a diluted concentrate.
Not ideal for: People feeding a range of houseplants or anyone who wants detailed dose instructions beyond the weekly or watering-time guidance.
- Brand:Gardenera
- NPK ratio:3-1-2
- Volume:8 ounces
- Form:Ready-to-use liquid mist
- Pack count:1
- Use:Peace lilies; indoor or outdoor
- Application guidance:Weekly or at watering time; shake well and avoid overwatering
Our verdict“Choose this mist if you want a ready-to-use 3-1-2 product for peace lilies and do not need one fertilizer for several plant types.”
TPS Nutrients Peace Lily Liquid Fertilizer, 8 fl oz
TPS Nutrients Peace Lily Liquid Fertilizer is aimed at growers who want a gentle liquid feed made for potted peace lilies, with stated support for roots, foliage, and flowering. Its 3:1:2 ratio puts it in the same nutrient-ratio category as Gardenera’s Liquid Peace Lily Fertilizer Concentrate, while its description emphasizes sensitive roots and the aim of preventing brown tips and yellowing associated with nutrient stress. Those outcomes are product claims, not guarantees, and the supplied details do not provide a mixing amount. That makes Gardenera’s concentrate easier to prepare consistently because it specifies one teaspoon per gallon. TPS is a narrower choice than Cute Farms Organic Liquid Plant Food, which targets houseplants broadly. I’d consider TPS for peace lily owners who prioritize plant-specific positioning, but its missing dose instructions make it less straightforward to use.
Pros:- Formulated specifically for potted peace lilies
- Stated 3:1:2 ratio
- Described as a gentle feed for sensitive roots
- Targets flowering, green foliage, and healthy root development
Cons:- Requires mixing before use
- No mixing ratio is included in the supplied product details
- Claims about preventing brown tips and yellowing are not guarantees
Best for: Peace lily owners seeking a plant-specific 3:1:2 liquid fertilizer and a formula described as gentle for sensitive roots.
Not ideal for: Buyers who need an explicit dilution ratio, want one food for a mixed houseplant collection, or expect fertilizer alone to prevent leaf discoloration.
- Brand:TPS Nutrients
- Form:Liquid
- Target plant:Peace lily
- Liquid volume:8 fluid ounces
- Item weight:0.31 kg
- Mixing ratio:3:1:2
- Country of manufacture:USA
Our verdict“Choose TPS Nutrients if you want a peace-lily-specific 3:1:2 liquid feed, but favor Gardenera’s concentrate if a stated dilution ratio is a priority.”
How We Picked
I compared these fertilizers on factors that shape a peace lily owner’s day-to-day choice: whether the product names peace lilies or targets houseplants broadly, the stated nutrient balance, application format, bottle size, and how much measuring or preparation the format appears to require. I also looked at the distinctions buyers can verify from the product information provided, such as organic or kelp-based positioning, concentrate versus ready-to-use formats, and whether a product is intended for spraying.
The ranking favors clear fit for peace lily care, useful and legible formula information, and a format that matches a practical feeding routine. A purpose-labeled 3-1-2 fertilizer ranks ahead of a broad houseplant feed when specificity is the priority; versatile formulas remain strong choices for mixed collections. Sprays and specialty ingredient options rank for their particular use cases rather than being treated as direct replacements for every liquid feed. The list does not assume that a larger bottle, an organic label, or a more specialized name guarantees better plant results; buyers should follow product directions and account for their own plant-care habits.

Factors to Consider When Choosing Best Peace Lily Fertilizers
Choosing among peace lily fertilizers is less about finding the strongest-sounding formula and more about matching the product to your plant, routine, and tolerance for measuring. I’d use these factors to narrow the options before buying.
Match the formula to your plant collection
A peace-lily-specific formula can make the choice simpler when this is the main plant you feed, while a general indoor-plant fertilizer may suit a varied collection. A stated NPK ratio, such as 3-1-2, tells you the relative amounts of nitrogen, phosphorus, and potassium, but it does not by itself tell you how often to apply the product or how your plant will respond. Read the label for dilution and frequency rather than inferring a feeding schedule from the ratio. If you keep peace lilies alongside plants with different needs, a broader formula may be more convenient, but avoid assuming one routine suits every pot. Choose specificity when it helps you follow one clear plan; choose versatility when fewer products matter more.
Decide whether concentrate or ready-to-use liquid fits
Concentrates can be compact and useful when you feed several plants, but they require accurate measuring and dilution. That extra step creates room for mistakes, especially if you estimate rather than use the directions. Ready-to-use products reduce preparation, though they may take more storage space and run out sooner in a large collection. Compare the label’s dilution instructions and the amount of finished solution you can make, not just the bottle size. A smaller concentrated bottle may go further than it appears, while a larger bottle is not automatically better value if you only have one plant. Pick the format you can use consistently and correctly.
Treat spray fertilizer as a format choice
Sprays are appealing when you want a quick application, but spraying foliage and feeding through the potting mix are not interchangeable routines. Check the product directions to see where it should be applied and how frequently. Avoid adding a spray on top of an existing fertilizer schedule without checking whether the label permits that combination. More frequent applications do not necessarily mean faster or healthier growth, and excess feeding can be hard on a houseplant. If ease of application is your priority, choose a spray with clear instructions; if you prefer measured feeding through watering, a liquid fertilizer may fit better.
Choose ingredients to match your preferences, not a promise
Organic and kelp-based products may appeal if ingredient sourcing or a particular formulation matters to you. Those descriptors do not remove the need to follow application instructions, and they should not be treated as a guarantee of faster growth or better flowering. Compare the full label, including the stated nutrients and directions, rather than choosing on a single ingredient claim. If you prefer a conventional indoor-plant food, a broad formula can still be a practical fit for a mixed collection. When you are switching products, avoid applying several new feeds at once; that makes it harder to tell which routine your plant tolerates.
Buy for your feeding frequency and storage habits
A large bottle may be a sensible fit for several plants, but a single peace lily may use fertilizer slowly. Before choosing a larger container, check storage guidance and whether you can use the product within the period stated on its label. Smaller bottles can reduce leftover product and are convenient if you are trying a format for the first time. Multipacks may suit regular houseplant care, yet they are less appealing if you feed infrequently or want to change formulas. Think about how often you actually fertilize and how many plants share the product. The right quantity is the one you can store and use as directed.
Use plant condition to decide when to feed
Fertilizer is not a fix for every yellow leaf or stalled plant. Changes in light, watering, drainage, or root health can also affect a peace lily, and adding nutrients without identifying the cause may not help. Check basic care conditions before increasing feeding, especially if the plant is already stressed. Follow the product’s label and avoid making up a stronger dose to compensate for slow growth. A consistent, conservative routine is easier to adjust than repeated changes in product and strength. If symptoms persist, review the plant’s overall care rather than relying on fertilizer alone.
Frequently Asked Questions
Is a peace-lily-specific fertilizer better than a general indoor-plant food?
Not automatically. A peace-lily-specific product can make it easier to choose a formula and routine for a plant you care for on its own, while general indoor-plant food can be more practical when you feed several houseplant types. Compare the stated nutrients and directions on both labels instead of relying only on the product name. If your collection includes plants with different feeding needs, one broad fertilizer may be convenient, but check whether its directions fit each plant. Choose the option whose instructions you can follow reliably.
Should I choose a liquid fertilizer or a spray for my peace lily?
Choose based on the application method you will use consistently and the directions on the label. A liquid feed may be suited to measured application through watering, while a spray is designed for a different use pattern. Do not assume a spray replaces soil-applied feeding or combine both formats without checking instructions. If you are unsure, begin with one product and keep the routine simple. The format alone does not tell you how often to feed, so follow the specific label.
Does a 3-1-2 NPK ratio mean I can use less fertilizer?
No. The NPK ratio describes the relative proportions of three nutrients, not the dose or application schedule. Use the dilution and frequency stated on the product label, even when the ratio looks suitable for peace lilies. Do not increase concentration because the plant seems slow to grow, since growth can also depend on light, water, season, and root condition. If you change products, use the new label’s directions rather than carrying over an old routine. Keeping notes can help you spot whether a change in care coincides with a change in plant condition.
Can I use one fertilizer for my peace lily and my other houseplants?
Sometimes, but check the product label against the needs and directions for each plant rather than assuming all houseplants should follow one schedule. Broad indoor-plant foods are designed for wider use, while peace-lily-labeled formulas may be a better fit when this plant is your main focus. A shared product can simplify storage, but different plants may still need different dilution or timing. Keep track of which plants you feed and when, especially if you use a concentrate. If a plant responds poorly, reassess its care and the label rather than applying more.
How do I choose a bottle size if I only have one peace lily?
Estimate how slowly you use fertilizer by considering the product’s directions, bottle size, and your intended feeding routine. A large container or multipack may be unnecessary for a single plant, particularly if you feed sparingly. A concentrate can take less storage space, but it requires accurate dilution and may still leave unused product if you rarely feed. Check storage instructions and avoid buying a quantity you are unlikely to use as directed. A smaller bottle is often the simpler starting point when you are trying a new formula or format.
Conclusion
For a single peace lily and a clear, plant-specific formula, I’d start with GARDENWISE Peace Lily Liquid Fertilizer as the best overall pick. For shoppers seeking a peace-lily-labeled 3-1-2 option in a larger bottle, FOLLOWIN is the best value-style choice in this lineup; buyers who want an organic ingredient approach can look to Gardenera Organic Liquid Kelp Fertilizer as the specialty pick. Beginners may find a broad liquid houseplant food such as Miracle-Gro Indoor Plant Food easier to fit into a mixed-plant routine, provided they follow its directions. For a spray application, compare the peace lily spray options and use the product only as its label directs. Choose by formula, format, and how many plants you feed—not by bottle size or a product’s name alone.
