Lime: an ally of the garden
After being shunned for many years, lime is back in the gardens. She is especially appreciated for her disinfecting virtues, but also for his ability to improve the quality of the land. It is, in addition, an effective product, both for preventive and curative purposes, and whose applications are very broad.
There are different kinds of lime that differ in their hardness. For the garden, we mainly use whitewash (or arboreal white), a whitewashed old-fashioned white, ideal for maintaining an organic garden.
The price of a lime pack of 10 kg costs about 20 € and can treat about 150 m² of land. It is possible to buy lime directly in a garden shop or via specialized websites.
The many uses of lime in a garden
Lime can be used in many ways because its properties are multiple : antifungals, antiseptics and antibacterials. Liming the garden is effective in preventing and treating wet areas infested with mold. It then applies directly to the targeted areas. It can be put on the lawn to remove the moss or eliminate weeds.
Lime thus acts as weed killer and this product is also very interesting to take care of fruit trees. The trunks of trees painted white are often seen in early winter. It's actually a whitewash that allows you to protect the tree against pests and insects (even larvae), molds, fungi, lichens and mosses.
Finally, since lime is capable of modifying the pH of the earth, it improves the fertility of the earth. Using lime in a garden is simply unavoidable for excessively acidic soils.
Be careful, the liming should be spaced every two to three years, preferably in autumn. The treatment is carried out, in addition, before any plantation, in the absence of organic amendment (fertilizer or manure). The doses of lime are to calculate according to the nature of the soil (limestone, sandblast, clay...) but it is not necessary to bring more than 150 - 200 mg / m². It is recommended that you read the instructions carefully before applying the product.
And on the side of use, precautions are necessary. Indeed, lime is corrosive and can cause skin burns or breathing problems. The gardener must absolutely protect with gloves, a mask, glasses and a suit.
