Fertilizers: 4 Effective Natural Fertilizers to Do Yourself

We tend to let nature do its work for outdoor plants, but when it comes to fertilizing indoor green plants, we tend to neglect them. Even if the green plants you just purchased will benefit from a very fertile environment in their original pot, what will it be like in two or three months? We offer 4 simple ways to provide vital nutrients to your plants. They are 100% natural, economical, and based on the recycling of substances and materials that you use almost every day.

1 – EGGSHELLS

Rich in calcium and therefore good for plant growth, eggshells will counteract the rotting of tomato flowers. This problem happens if your soil lacks calcium. To remedy this, simply crush egg shells and bury them below the surface of the soil.

Please note: for optimal effectiveness, you can also use a spray by mixing around twenty eggshells and 4 liters of water. Boil everything for a few minutes, and leave to infuse in water overnight. Use a strainer and pour the liquid into a spray bottle. Spray directly onto the soil.

2 – COFFEE GROUNDS

Rich in phosphorus and nitrogen, coffee grounds are used for salads, certain aromatic plants and foliage shrubs all year round. It is incorporated into the soil, but can also be added in small quantities to seedling or potting soil. For fruit trees and flowering plants, it is better to limit one application in spring to encourage regrowth after the winter rest. Its use is not recommended during the flowering period, because a supply of nitrogen causes the leaves to grow to the detriment of the flowers.

3 – BANANA SKIN

Very rich in potassium, phosphorus and calcium, banana peel optimizes plant growth and stimulates flowering (roses especially love it). Potassium also helps revive the colors of the flowers! Cut the skin into small pieces and bury them at the base of the plants. The skin will decompose and feed the plants. It is also possible to let the banana peel infuse in a sprayer for 3 days and spray the soil directly.

4 – WOOD ASHES

Do you have a fireplace, stove or insert? All in good time ! Rich in calcium, potash, silica, magnesium and phosphorus, wood ashes complement the virtues of nettle manure.

Please note, it must be untreated wood, without paint or varnish, so as not to put toxic substances in your floor. Then collect the ashes and let them cool before passing them through a sieve.

Don’t hesitate to store them in bags to spread them whenever you want. All you have to do is spread it at the base of the plants, scratching the ground to make them penetrate. Phosphorus helps in the production of flowers and fruits, this fertilizer is ideal at the foot of fruit trees, flowering plants and in the vegetable garden.
