here are the nutrients to provide it

Why amend your soil in fall change everything for spring

In autumn, the earth still benefits from a certain warmth, ideal for integrating nutrients. This time of year provides an excellent opportunity to prepare the soil, as soil microorganisms can still work before going into rest. Amending now helps nourish the soil without disturbing the plant life that develops there in spring.

By making a good amendment in the fall, you optimize growing conditions for the following season. Plant roots will have enriched soil, microorganisms will benefit from nutrients to decompose, and your garden will be ready to face the climatic challenges of spring.

Nitrogen, phosphorus and potassium: the winning trio for a balanced soil

To effectively prepare your soil for winter, it is essential to provide it with the three main nutrients: nitrogen, phosphorus and potassium. These nutrients each play a fundamental role in the health of the land and plantations.

1. Moderate nitrogen intake for a fertile soil

Nitrogen is essential for leaf and stem growth, but too much can stimulate unwanted growth as winter approaches. This is why it is recommended to add a small amount of nitrogen in the fall to enrich the soil without causing excessive development.

• Natural nitrogen source : Well-ripened compost is ideal, as it releases nitrogen slowly without excess. Around 1 to 2 cm of compost on the surface is enough to guarantee a balanced supply.
• Practical tip : Avoid fast-release, high-nitrogen fertilizers, as they may stimulate unnecessary growth and deplete resources in winter.

2. Phosphorus: strengthen the root system before winter

Phosphorus is the nutrient of choice to stimulate root development. It promotes the depth and robustness of the roots, making plants more resistant to low temperatures and bad weather during the cold season.

• Source of phosphorus : Fish meal or bone residue are excellent sources of natural phosphorus. Apply a thin layer to the base of shrubs and other perennial plants.
• Additional benefit : A soil enriched with phosphorus will also be more reactive from the first days of spring, which promotes a rapid start of crops.

3. Potassium : the natural shield against the cold

Potassium is a real ally for strengthening the natural defenses of plants. It improves their resistance to frost and helps fight diseases. By amending the soil with potassium, you increase the plants' ability to withstand climatic stresses.

• Source de potassium : Wood ashes (untreated) are ideal for a natural supply of potassium. Approximately 70 g of ash per square meter is sufficient for an effective amendment. Be sure to mix them well with the soil to avoid a concentration on the surface which could harm certain plants.
• Gardener's advice : Apply the ashes on a windless day to prevent them from scattering, and make sure to distribute them well for optimal effect.

Organic matter: compost, manure and green manure, a revitalizing cocktail

In addition to nutrients, soil needs organic matter to maintain good structure and nourish microorganisms. In fall, three organic matter options are available to you for healthy soil.

Compost: nourish the soil gently

Compost is an excellent natural amendment, rich in decomposed organic matter. By spreading it on the surface, you help the soil remain loose and fertile while providing essential nutrients for spring.

• Recommended quantity : About 2 cm of compost spread over the surface. If your soil is particularly poor, do not hesitate to increase the thickness slightly.
• Advantage : By slowly decomposing over the winter, compost gradually releases nutrients into the soil.

Manure: a boost for depleted soils

Manure, although odorous, is a powerful amendment that intensely nourishes the soil. It is particularly useful for depleted soils or greedy crops.

• Type of manure : Use well-rotted manure (horse, cow or sheep manure), as too fresh manure could burn young plants.
• Quantity : Spread a thin layer (approximately 1 to 2 cm) and mix lightly with the soil for a balanced effect.

Green manure: protect and enrich the soil naturally

Green manure, such as mustard or phacelia, is a plant cover that protects the soil from erosion and enriches the soil when buried. Sown in autumn, green manure limits nutrient losses and promotes microbial life.

• Advantage : Once mowed, this plant cover decomposes and becomes nutrient-rich humus.
• Good to know : Legumes like vetch also provide nitrogen, making them a doubly useful fertilizer for the soil.

The essential amendments for fall

Prepare your floor now to a resplendent garden in spring

Amending the soil before winter is a simple action that makes all the difference for a healthy garden. By providing the right nutrients and organic matter now, you provide your soil with a solid and balanced foundation. In spring, your plants will benefit from rich, fertile soil, ready to deeply nourish their roots.

So, before the cold sets in, take a few hours to enrich your soil with this natural cocktail of nutrients. With well-prepared soil, you maximize the chances of vigorous flowering and healthy growth as soon as the warm weather returns.
