Apply the coffee groundwater to the potting soil. Supplies nitrogen, potassium and phosphorus to the plant to promote better leaf growth.

peel bananas

Banana peels are rich in potassium, magnesium, phosphorus, and nitrogen. These components are excellent natural slow-release houseplant fertilizers.

You should cut the banana peels into small pieces and mix them with the potting soil. Another option is to puree in water and pour over potting soil.

The pieces of banana peel will break down and release nutrients to the plant. Decomposed banana peels are the best organic fertilizer for houseplants.

Green tea bags are a suitable and economical natural fertilizer for indoor plants. But this homemade houseplant fertilizer recipe is ideal for those plants that thrive in an acidic environment.

The tannic acid in green tea bags tends to lower the pH of the soil. It also increases the concentration of nutrients that promotes the healthy growth of indoor plants.

milk powder

It is a nutritious fertilizer for indoor plants. Powdered milk is rich in calcium, which helps improve soil quality and fertility.

Before planting the houseplant, mix diluted milk powder into the garden soil. Slow release fertilizer provides essential nutrients for your houseplants.

Wood ash from fireplaces

Wood ash contains calcium and potassium carbonate minerals. These elements ensure better growth and well-being of indoor plants.

Before watering, apply a small amount of wood ash to the potting soil. Plant roots can easily absorb dissolved wood ash.

Wood ash also helps get rid of bugs around the houseplant. The double impact turns wood ash into the best homemade compost.

rice water fertilizer

Soaked rice water is another great homemade liquid fertilizer for houseplants. But it is a soft fertilizer, although rich in NPK.

The starch in the rice water helps facilitate the growth of beneficial bacteria in the soil. The NPK in potting soil promotes good growth and health.

Soak the rice in water for about 2-3 hours and drain it. Use the rice water to water your indoor plants. The vital elements in rice ensure healthy plant growth.

kitchen compost

Compost contains essential nutrients and microorganisms for your houseplants. It is the best organic fertilizer for indoor plants.
