Natural fertilizers promise vigorous plants without damaging the environment. Derived from plant, mineral or animal materials, they give a boost to ornamental plants and vegetable gardens.
Discover the 3 best do-it-yourself natural fertilizers for the garden!
In order to grow well, show beautiful flowers, yield fruit and avoid succumbing to disease, plants need sunlight, water and nutrients. Depending on the requirements of each plant, it is easy to choose a suitable location, more or less sunny. The same goes for a more or less cool substrate and regular watering.
When it comes to nutrients, it is often necessary to add fertilizer. We ban chemical fertilizers that destroy microbial life and end up impoverishing the soil! Instead, bet on natural fertilizers to make yourself!
Plants need three nutrients: nitrogen (N), phosphorus (P) and potassium (K). Nitrogen is used for leaf and stem growth, while phosphorus promises beautiful flowers and profuse fruiting. As for potassium, it strengthens plants and enables them to be more resistant to diseases and pests. Added to this are elements such as iron, calcium, magnesium or sulfur.
The 3 best fertilizers for the garden
It is the flagship organic fertilizer of the garden! Compost is beneficial for plants because it combines multiple benefits. For example, banana peels are rich in potassium, phosphorus, and calcium. The coffee grounds generates nitrogen just like green waste (grass, radish tops, peelings, etc.). So, by combining all these residues you get an over-vitamin cocktail for your plants!
Those who have a garden will be able to build their own compost silo, while those in an apartment will benefit from models suitable for the balcony or for indoors. You can individually place banana peels at the foot of flowering plants and coffee grounds for heather earth plants. For tomatoes, go for fish heads, eggshells or baking soda.
If nettle manure is used so much in the garden, it is not for nothing! It is very rich in nitrogen and also acts as a repellant against many pests such as aphids. It is also used as a compost activator. It is therefore useful for growing your plants, strengthening them, preventing certain pests or even repelling them. Its preparation is very simple! All you need to do is arm yourself with gloves and go nettle picking. Collect 1kg of nettle then roughly chop them. Place them in a cloth bag or other container that allows water to pass through but keeps the nettles in place. Put the bag in a basin that you fill with 10L of water. Let macerate, taking care to stir once a day with a stick. As long as small bubbles rise to the surface, the preparation is not yet ready. Thanks to the fabric bag, no need to filter! You just have to pour your mixture into bottles or cans. Every spring in the vegetable garden, spray it on the plants diluted to 10% in rain water. You can also dilute it in the same way by using it in irrigation water twice a month during the growing season of ornamental plants, especially those in pots!

Do you have a fireplace, a stove or an insert? All in good time ! Rich in calcium, potash, silica, magnesium and phosphorus, wood ashes complement the virtues of nettle manure.
Be careful, this 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 foot of the plants, scratching the ground to make them penetrate. Since phosphorus helps in the production of flowers and fruits, this fertilizer is ideal for fruit trees, flowering plants and vegetable gardens.
