Here is a selection of natural fertilizers that will help your flowers flourish safely!
What are the best fertilizers for your garden?
Industrial and chemical fertilizers are not necessarily the best solution to obtain beautiful, healthy and durable plants. Quite the contrary. Despite their proven effectiveness in promoting their growth, these artificial products are also known for their harmful and aggressive effects. However, with natural ingredients, you can have just as satisfactory results, or even more. To grow up to twice as many flowers outdoors, there’s nothing like a natural organic fertilizer that respects the treasures of Mother Nature. As a bonus, you probably already have everything you need at home!

How to prepare this natural fertilizer made from raw white rice? Ideally, try to get untreated beans, that is, without the addition of additives or preservatives. Here are the steps to follow:
- Pour 100 g of rice into a container and add 1 liter of water.
- Mix thoroughly and leave to soak for about 24 hours. This will allow the rice to release all of its nutrients into the water, which will then be used on the plants.
- After this time, the rice will have a tender texture. Mix again and filter through a sieve. Even if it is the liquid that we are interested in, you will not be wasting anything: you can use the grains as a natural organic fertilizer, applying it to the soil to create a nutritious substrate that will make the plants grow more faster and healthier. As a bonus, adding rice grains will enhance the beneficial effect of liquid fertilizer.
- The rice water is now ready for use: however, before using it, it is advisable to dilute it in water (1 cup of fertilizer for 10 liters of water). Once the operation is done, you can pour it on the ground around the plants or on the leaves, according to the needs of each plant.
Good to know : it is recommended to use this natural fertilizer based on white rice every two weeks, to obtain vigorous plants and abundant flowering.

You used to throw coffee grounds after use? It’s a shame, because this product, often underestimated, can do wonders in your garden. Rich in nitrogen, sulfur and phosphorus, it acts as an ideal fertilizer to nourish your plants. Note that the roasting process completely breaks down plant protein, but the plant nutrients are largely retained in the breakdown products. How to use it as fertilizer? It’s hardly worth going to the garden with a single used filter and sprinkling it around the plants. The best thing is to place it in a bucket and keep it in a dry but ventilated place. To help it dry faster, hang a fine-mesh sieve to prevent mold. When dry, sprinkle a few handfuls around the roots of each plant. The coffee grounds will have a slightly acidic effect on the soil and enrich it with humus.

When is the best time to fertilize the garden?
It is during the period of their growth that plants benefit most from the benefits of fertilizers. Therefore, the best time to fertilize them is in early spring when they are emerging from dormancy. But remember, each has unique individual fertilizer needs. Acidophilous plants such as azaleas, blueberries, camellias, hydrangeas and rhododendrons notably prefer a more acidic soil pH to absorb nutrients. Flowering or fruiting plants need more phosphorus to help stimulate the growth of buds, fruits and flowers.
Where to find natural nitrogen?
The richest organic sources of nitrogen are: manure, ground animal parts and meal (soybean meal or cottonseed meal). The concentration of nitrogen in manure varies according to the type of animal, but also according to the age of the manure and the way in which it was stored. As for animal carcasses and seed meal, as they undergo special treatment, they generally have a very high concentration of nitrogen.
