Houseplants Care: Homemade Fertilizer For Peace Lilies

I just think that anybody should have a Peace Lily as a houseplant. Yes, Peace Lily is dangerous for pets, because it’s toxic if eaten in large quantities. However, Peace Lily is one of the best air purifying potted plants that will cleanse the indoor air of pollutants.

Peace lilies aren’t fussy and they really don’t need much fertilizer. The best time to apply peace lily fertilizer is when the plant is activity growing or producing blooms. As a general rule, two or three feedings throughout the growing season is plenty. If you choose to feed your plant more often, use a very diluted fertilizer.


Keep In Mind: too much fertilizer may create brown spots on the leaves. If the flowers are a little green around the gills instead of creamy white, you are probably overdoing the fertilizer. Either cut back or dilute the concentration.

In order to avoid killing Peace Lily by overfeeding it, you can rely on natural fertilizers based on:

Epson Salt

  • Mix 1 tablespoon of Epsom Salts into 1 gallon of water in a jug or pitcher.
  • Shake or stir the mixture thoroughly.
  • Apply this solution to your peace lily every 4 to 6 weeks in place of a water application.
  • Shake the container before each use.

Fish Tank Water

  • If you have a fish tank, save the water from a tank cleaning in a clean jug.
  • Shake the water and apply to the base of the peace lily every month in place of a water application.
  • This homemade fertilizer will provide much-needed nitrogen to your plant.


  • Mix 1 tablespoon of white vinegar into 1 gallon of water in a jug or pitcher.
  • Shake or stir the mixture and apply to your peace lily once every three months in place of water application.


  • Rinse out empty milk cartons and apply it to the base of your peace lily.
  • Milk contains nitrogen, phosphorous and potassium – all components of a basic commercial fertilizer.
