When cultivating a garden, good soil moisture management is essential. Indeed, water is a vital element for plants, but it can also evaporate quickly depending on weather conditions. Fortunately, there is an effective solution to limit this excessive evaporation: mulching. This technique consists of covering the surface of the soil with organic or mineral materials, in order to maintain a certain humidity. Thus, the plants benefit from an environment favorable to their development.
What is mulching ?
Mulching is an ancestral technique which consists in covering the ground around the plants with natural or artificial materials. These materials can be organic mulch (such as dead leaves, wood bark, straw) or mineral mulch (such as gravel, sand or pebbles). The main purpose of mulching is to maintain a protective layer that regulates soil moisture by limiting evaporation.

The benefits of mulching
THE mulching has many benefits for a healthy and productive garden:
1. Moisture preservation
Covering the soil with a layer of mulch provides a good barrier against water evaporation. Thus, the humidity of the soil is better preserved, which reduces the need for watering while keeping the plants well hydrated.
Mulching also acts as natural thermal insulation. By covering the soil, it helps to maintain a more constant temperature, thus protecting the roots of plants against variations in heat or cold.
Mulching Techniques: Preserve Soil Moisture
What is mulching and why is it important?
Mulching is a word that often comes up in the field of gardening. But what is this technique that everyone is talking about? And above all, why is it so important to preserve soil moisture? Well, let me explain it to you!
Mulching consists of covering the surface of the soil with a layer of organic or inorganic materials. These materials can be varied: straw, cut grass, wood bark, compost, dead leaves, etc. Their benefits are numerous and help preserve soil moisture.
The benefits of mulching to preserve soil moisture
Mulching acts as a natural barrier that limits the evaporation of water contained in the soil. By covering the earth, it protects the roots of plants from excessive heat and the sun’s rays. Thus, the humidity is maintained longer, which allows the plants to hydrate better and withstand prolonged periods of drought.
Additionally, mulching helps regulate soil temperature, keeping it cool in the summer and protecting it from the cold in the winter. This promotes the development of useful soil organisms, such as earthworms, which contribute to its aeration and fertility.
What mulching techniques to use?
There are different mulching techniques and materials that you can use in your garden. Some manufacturers even offer products specifically designed to optimize soil moisture, such as the brand GreenGarden with its biodegradable and environmentally friendly mulch.
Organic mulches, such as straw, grass clippings or dead leaves, are particularly recommended for vegetable gardens and flower beds. They decompose little by little and nourish the soil by releasing nutrients.
As for inorganic mulches, such as wood bark or slate, they are more durable and can last for several years. They are ideal for large spaces such as driveways or ornamental beds.

Give yourself a chance to improve your soil health by using the right mulching techniques. Your garden will thank you! So, get your mulches and hoes ready, set off for a great gardening season!
3. Weed reduction
Mulching blocks light from reaching weeds buried in the ground, limiting their growth. Fewer weeds means less competition for nutrients and water, thus benefiting crop plants.
4. Soil enrichment
Organic mulch breaks down over time, releasing nutrients that enrich the soil with organic matter. This promotes microbial life and improves soil structure, allowing plants to grow better.
How to mulch your garden?
There are different mulching techniques, depending on preferences and available resources. Here are some ideas to get you started:
1. Organic mulch
– Use dead leaves, grass clippings, wood bark or straw to cover the ground. These materials slowly break down and provide nutrients to the soil.
2. Mineral mulch
– Opt for gravel, pebbles or sand for a mineral mulch. These materials are durable and retain moisture well.
3. Plastic mulch
– Plastic mulching films are practical for large cultivated areas. They limit evaporation but must be used with caution so as not to completely block the water supply.
Q: What thickness of mulch to use?
A: It is recommended to put a layer of mulch about 5 to 10 centimeters thick. This allows for maximum efficiency in preserving moisture.
Q: Should I remove the mulch in the winter?
A: It’s best to remove some of the mulch in the winter so you don’t choke the plants. You can put it back in the spring when the temperatures warm up.
Q: Does mulch attract pests?
A: In most cases, mulch provides shelter for certain garden-beneficial insects. However, it is important to monitor the possible presence of pests and to intervene if necessary.
By using the mulching techniques, you can preserve soil moisture, reduce evaporation, limit weeds and improve the health of your plants. Whether organic or mineral, mulch is a simple and effective solution for a thriving garden. So, don’t wait any longer and adopt this technique now!
