Best Liquid Fertilizer For Peace Lily: 10 Options Compared

#1 · Best Overall

1. TPS Nutrients Peace Lily Liquid Food

• Form: Liquid
• Weight: 8 oz

Best for: Gentle potted-peace-lily feeding.

Why it ranks #1: Made specifically for peace lilies, it promises gentle, consistent feeding for potted plants and supports blooms, foliage, and root development.

Gentle, consistent nutrition for peace lilies grown in pots is the defining feature of this TPS NUTRIENTS liquid food. It supports balanced growth, richer foliage color, and flowering while addressing the needs of sensitive roots, making it a focused option for indoor peace-lily care.

The formula supports nutrient uptake and healthy roots, which can help a peace lily use water and nutrients effectively. Its listed benefits also include fresh leaf and stem growth, fuller foliage, and elegant white blooms, so it speaks to both plant structure and flowering. The liquid form suits a routine centered on watering potted indoor plants. Made in the USA, it is specifically positioned for peace lilies rather than a broad range of houseplants.

Skip it if you want one fertilizer for several houseplant types; Miracle-Gro Indoor Plant Food for All Plants covers indoor container plants broadly.

Choose this for a potted peace lily when you want liquid nutrition supporting roots, foliage, and blooms in one plant-focused product. Its stated use is specific to peace lilies, so it is less suited to a mixed houseplant collection.

#2 · Best Mixing Directions

2. Gardenera 3-1-2 Peace Lily Fertilizer

• Form: Liquid
• Weight: 8 oz

Best for: Measured concentrate for peace lilies.

Why it ranks #2: This peace lily-specific 3-1-2 concentrate gives a clear dose: one teaspoon per gallon, applied at the roots on the watering schedule.

A 3-1-2 concentrate with a teaspoon-per-gallon mixing direction gives this Gardenera fertilizer a clear, repeatable feeding routine. The product is formulated for indoor peace lilies, and its organic formula suits growers who want plant-specific nutrition prepared with their regular watering.

Mixing one teaspoon of concentrate into one gallon of water turns the 8-ounce liquid into a watering solution, with feeding directed at the roots. The directions call for application every alternate watering, giving growers a defined cadence rather than an unspecified schedule. Its 3-1-2 blend supplies nitrogen, phosphorus, and potassium, and the product is labeled organic. That combination makes it a focused choice for peace-lily care, not a general-purpose houseplant formula.

Skip it if you prefer a kelp-focused solution with dilution ratios and a 2–4-week schedule; Gardenera Seaweed & Kelp Superfood provides that routine.

This suits peace-lily owners who appreciate measured root feeding and a stated alternate-watering cadence. Choose it for a concentrated 3-1-2 formula, while keeping its dilution and schedule instructions in mind when planning regular plant care.

#3 · Best Variety Coverage

3. Leaves and Soul Peace Lily Fertilizer

• Form: Liquid
• Weight: 8 oz

Best for: Multi-stage peace-lily care.

Why it ranks #3: Its peace lily-focused 3-1-2 formula is listed for young and mature plants and named varieties including Sensation, Domino, and Petite.

Compatibility with peace lilies from young plants and recent divisions through mature specimens sets this Leaves and Soul fertilizer apart. Its 3-1-2 liquid concentrate is formulated for peace lilies, giving growers a plant-specific option to incorporate into regular care as their plants develop.

The 3-1-2 formula is presented as support for roots, green foliage, and blooms, connecting its nutrient blend to the main stages of peace-lily growth. Its listed compatibility includes Spathiphyllum wallisii, Sensation, Domino, Petite, young plants, divisions, and mature peace lilies. That range helps growers keep one plant-focused product in their routine as a collection changes or a specimen matures. The concentrate is liquid, and the listing identifies it as made in the USA.

Skip it if you want a single feed for many indoor plant types; Houseplant Resource Center Indoor Plant Food lists peace lilies alongside pothos, monstera, and cactus.

Pick this for a peace-lily collection spanning young plants, divisions, and mature specimens, especially if cultivar coverage matters. It is a focused plant-food choice, so consider a broader houseplant fertilizer if you want one product for unrelated plants.

#4 · Largest Listed Yield

4. HiThrive Peace Lily Fertilizer

• Form: Liquid
• Weight: 1.2 lb

Best for: High-volume peace-lily concentrate.

Why it ranks #4: This plant-specific 6-2-4 formula includes six micronutrients, and its 16-ounce bottle is stated to make 96 gallons.

A 16-ounce bottle stated to make 96 gallons of solution is the defining practical feature of HiThrive Peace Lily Fertilizer. Its 6-2-4 formula and six essential micronutrients are presented for peace lilies, giving frequent feeders a concentrated, plant-specific option.

The listed yield of 96 gallons from the 16-ounce bottle makes this a concentrated choice for growers who prepare fertilizer solution regularly. HiThrive connects nitrogen with greener leaves, phosphorus with stronger roots, and potassium with resilience, while also including six essential micronutrients. The 6-2-4 NPK ratio is identified for consistent growth across peace-lily varieties. That combination suits peace-lily care at scale, though the supplied information does not state a mixing dose or feeding interval.

Skip it if you need exact teaspoon-per-gallon instructions and a stated feeding cadence; Gardenera Premium Liquid Peace Lily Fertilizer lists both.

Consider HiThrive if you maintain several peace lilies or use concentrated solution regularly and value its stated yield. Its 6-2-4 profile is peace-lily-focused, but the available details leave the mixing dose and schedule unspecified.

#5 · Best Kelp Formula

5. Gardenera Peace Lily Kelp Fertilizer

• Form: Liquid
• Weight: 4 oz

Best for: Kelp-based peace-lily care.

Why it ranks #5: A peace lily-specific Ascophyllum nodosum kelp concentrate, it makes 45 gallons and lists separate 1:200 maintenance and 1:100 blooming dilutions.

Ascophyllum nodosum seaweed and kelp are the defining ingredients in this Gardenera peace lily concentrate. The 8-ounce bottle is stated to make 45 gallons, offering a concentrated plant-food option for growers who want a kelp-based approach for indoor or outdoor peace lilies.

The directions specify dilution at 1:200 for maintenance or 1:100 for blooming, connecting the concentrate to two distinct care needs. Apply the solution every two to four weeks, depending on growth stage and conditions, and water it to reach the roots. These details give growers a defined mixing and application routine. The formula is labeled organic and suitable for all peace lily cultivars, with the product description linking it to glossy leaves, white blooms, and healthy roots.

Skip it if you want a single teaspoon-per-gallon ratio instead of stage-based dilution; Gardenera Premium Liquid Peace Lily Fertilizer uses that simpler mixing direction.

Choose this for peace-lily growers who want an organic kelp concentrate and can follow separate maintenance and blooming ratios. Its indoor and outdoor cultivar coverage is broad, while the dilution changes with the growth stage.

6. TPS Nutrients Peace Lily Fertilizer Spray

• Form: Liquid

Best for: Mist-fed indoor peace lilies.

Why it ranks #6: This peace lily spray offers a mist application for indoor plants and is described as supporting foliage and flowering without requiring a concentrate-mixing step.

A spray-mist feeding method is the defining convenience of this TPS NUTRIENTS peace lily fertilizer. The liquid mist is intended for routine care of potted indoor peace lilies, offering a way to apply nutrients while supporting foliage development and consistent white flowering.

Rather than describing a concentrate to dilute, the listing emphasizes convenient spray feeding for routine plant care. That format makes the product a fit for growers who want to mist a home plant display while tending to potted peace lilies. Its stated benefits center on vibrant leaves and flowering, and the product is also described as supporting healthy plant development. The 16-ounce liquid spray is made in the USA, with no mixing ratio provided in the supplied information.

Skip it if you want a stated concentrate ratio and root-watering schedule; Gardenera Seaweed & Kelp Superfood specifies both dilution and application timing.

This fits an indoor peace-lily owner who prefers a misting routine for a home plant display and wants foliage and bloom support. Choose it for spray application; growers who plan feeding by measured dilution may prefer a concentrate.

#7

7. Houseplant Resource Center Indoor Plant Food

• Form: Liquid
• Weight: 9 oz

Best for: Chelated-nutrient houseplant feeding.

Why it ranks #7: Its 3-1-2 liquid formula and chelated micronutrients suit indoor foliage plants, and the product listing explicitly includes peace lilies among its uses.

Chelated micronutrients paired with a 3-1-2 NPK ratio distinguish Houseplant Resource Center Indoor Plant Food. The formula is listed for peace lilies as well as pothos, monstera, cactus, and other plants, making it a multi-species option for indoor growers seeking a shared feeding product.

The 3-1-2 ratio links nitrogen with foliage, phosphorus with root development, and potassium with overall vitality, according to the product details. Chelated micronutrients are included for long-term bioavailability, adding another stated part of the formula beyond its main NPK blend. Because peace lilies appear among the listed plants alongside pothos, monstera, and cactus, one product can cover a varied indoor collection. The liquid comes in an 8-ounce bottle with a flip-top cap and induction safety seal.

Skip it if you want a formula labeled specifically for peace lilies and multiple growth stages; Leaves and Soul Professional Peace Lily Fertilizer lists both.

This is a good match for a peace lily owner feeding several kinds of houseplants and looking for a 3-1-2 formula with chelated micronutrients. Its multi-plant scope is useful, but it is not labeled as peace-lily-only food.

#8

8. Grow Queen Organic Indoor Plant Food

• Form: Liquid
• Weight: 0.36 kg

Best for: Balanced all-purpose indoor feeding.

Why it ranks #8: The 5-5-5 formula includes sea kelp and is intended for indoor plants and tropicals, but it is not identified as peace lily-specific.

An equal 5-5-5 NPK ratio combined with sea kelp distinguishes Grow Queen Organic Liquid Indoor Plant Food. It is labeled for indoor plants, houseplants, and tropicals, making it a broad-use liquid option for peace lily owners who feed a mixed indoor collection.

The balanced 5-5-5 blend provides equal nitrogen, phosphorus, and potassium, and the formula also includes sea kelp. Its directions describe one capful, about 4 ml, per gallon of water, giving growers a measured way to prepare a watering solution. The listing states that it can be used at every watering and that the 8-ounce bottle treats up to 50 gallons. That routine and broad plant labeling suit a collection, though it is not peace-lily-specific.

Skip it if you want a peace-lily-only blend and variety-specific coverage; Leaves and Soul Professional Peace Lily Fertilizer lists multiple peace lily types.

This suits an indoor grower who wants one measured liquid feed for peace lilies alongside tropicals and other houseplants. Its every-watering direction and broad labeling are useful for collections, but it is not tailored exclusively to peace lilies.

#9

9. Miracle-Gro Indoor Plant Food

• Form: Liquid

Best for: Mixed indoor-plant collections.

Why it ranks #9: This liquid food is intended for indoor container plants, including flowers, but the listing gives no peace lily-specific formula or dose.

Coverage for all indoor container plants makes Miracle-Gro Indoor Plant Food a practical pick for peace-lily owners with a varied houseplant collection. The liquid food feeds instantly and is labeled for houseplants, flowers, vegetables, herbs, and other indoor potted plants, rather than only one species.

Because the product is labeled for all indoor container plants, one bottle can serve a peace lily alongside indoor flowers, vegetables, herbs, and other houseplants. Its instant-feeding claim offers a straightforward option for growers who want to apply liquid plant food during routine care. The listing says it contains nutrients for healthier, stronger plants when used as directed, while also noting that light needs and fresh potting mix remain part of plant care. It is a general indoor formula, not a peace-lily-specific blend.

Skip it if you want a peace-lily-specific formula and a listed NPK ratio; HiThrive Peace Lily Fertilizer provides a 6-2-4 blend for peace lilies.

Choose this if your peace lily shares a care shelf with other indoor container plants and you value broad labeling. Its general-purpose scope is useful for mixed collections, while species-specific feeding calls for a more targeted formula.

#10

10. Bonide Houseplant Liquid Plant Food

• Form: Liquid
• Weight: 10.56 oz

Best for: Frequent houseplant watering routines.

Why it ranks #10: Its 10-10-10 concentrate is designed for common houseplants, with directions for one-eighth teaspoon per quart, but peace lilies are not specifically named.

A direction to use the concentrate every time you water gives Bonide Houseplant Liquid Plant Food a clear place in regular care. Its 10-10-10 formula is labeled for common indoor houseplants, so peace lily owners can use it within a broader houseplant routine.

Bonide specifies mixing 1/8 teaspoon of concentrate into one quart of water, making the preparation amount explicit for each watering. Its 10-10-10 formula is described for houseplants, including orchids, succulents, ferns, and poinsettias, and regular use is stated to promote healthy growth. That broad houseplant coverage can suit a mixed indoor collection that includes a peace lily. The product is a liquid concentrate, and the supplied directions say to use it when watering.

Skip it if you want a dedicated peace-lily formula with a 3-1-2 ratio; Gardenera Premium Liquid Peace Lily Fertilizer is labeled specifically for indoor peace lilies.

Pick Bonide if you want a measured concentrate for a frequent watering routine and also care for other common houseplants. Its broad indoor use is convenient for a mixed collection, while its label does not focus on peace lilies alone.
