Thanks to the pro tips, here are the best natural fertilizer recipes to make at home without delay.

Fertilizer is a real ally for plants, which should not be neglected, especially when planting, which takes place in spring for most plants. Fertilizers used during fertilization provide plants with nutrients, giving them a boost when they (re) grow after a period of rest. Like humans, plant health sometimes requires vitamins in addition to good soil. Among them, nitrogen which makes the stems and leaves grow, phosphorus which contributes to rooting, potassium which strengthens plants and rooting, and calcium and iron are also essential vitamins to ensure that the plants bloom as best as possible. Be careful not to overdose on fertilizer, however, as this can be harmful to your plants. Be sure to follow the fertilization directions for each plant, as the dosage varies.

It is better to do without chemical fertilizers which contribute to soil and water pollution and can also lead to health problems. Many natural and organic fertilizers can be found today on supermarket shelves or garden centers, but you can also opt for a homemade natural fertilizer from the recycling of various ingredients located in your home. An easy recipe that helps your plants, does not pollute and simultaneously recycles your waste? What better ! Thanks to the tips of several landscapers, we give you the most effective homemade fertilizer recipes to boost the flowering of your aromatic herbs, your fruits and vegetables, and all your plants.

A banana peel concoction

Banana peel is full of potassium, phosphorus, and calcium, which is great for flowering and plant reproduction. It is best to use organic banana peels in order to avoid a chemical fertilizer that may contaminate your garden soil and water due to excess nitrate and phosphate. That said, here is a banana peel recipe to make at home:

  • In 1 jar that closes, mix 3 banana peels and water,
  • Leave to ferment for three days,
  • Gradually diffuse this liquid in the potting soil of potted plants inside your house and on the soil of your garden. Nothing could be simpler or more efficient!

Nettle manure, a doubly beneficial recipe

In his new book “A natural vegetable garden”, blogger Tom the Gardener reveals that nettle manure is not only “rich in nitrogen”, but also “serves as a repellant against many pests”. Here is a recipe that can be kept for a maximum of one year in the fridge in airtight jars, and which not only promotes the growth of your plants, but also makes them more resistant to diseases:

  • 500g young nettles, not seeded and coarsely chopped
  • 5 l of water in a container

Macerate the nettles in water at room temperature for a minimum of 15 days,
Filter the mixture, pour into a watering can or sprayer and spray on your plants.

The essential tools to master the art of fertilizer

Fill up on nitrogen with the coffee grounds

According to Tom the Gardener, recipes based on coffee grounds are also essential for any good gardener with natural methods. Rich in magnesium and nitrogen, coffee grounds are an excellent fertilizer for plants, particularly appreciated by rose bushes. Place your morning coffee grounds directly on the soil near your plants; it couldn’t be easier!

End your food waste with organic compost

Besides banana peels, your food waste contains a variety of essential vitamins for plants: while green waste (such as grass, radish tops and peelings), the cooking water of your vegetables and the contents of tea and infusion bags generate nitrogen, eggshells are rich in calcium. Like coffee grounds, spread a layer of this very ripe organic waste (from animals or plants) at the foot of your plants on the ground to give them a boost. As with banana peels, organic fruit and vegetable waste should be prioritized in order to protect the environment from chemical fertilizer.
