Like snails, slugs are molluscs that fall into the category of gastropods. Needing a minimum of moisture to move around, their appearance usually coincides with the rain. Here's how to eliminate slugs in a garden?
Slugs are voracious
Slugs are gastropods that need to "slide" to move. For this, they produce mucus, which is possible only by very wet weather. As a result, slugs come out only when the soil is wet. This is the case after watering, after a rain, but also in the early morning and evening. Slugs mainly consume fresh or nearly decomposed plants close to the ground and having a soft texture. They also attack fruits, leaves and seeds. In dry weather, these gastropods can also sinking into the ground and attack tubers, bulbs and roots. To limit / avoid damage, every gardener must eliminate slugs...
How to eliminate slugs in a garden?
- The simplest gesture: picking slugs
The simplest and most common solution is simply to pick slugs daily. This option is more suitable for large slugs and "pick-up" is best done early in the morning. But it is a time-consuming and restrictive action, and more effective only in the short term. It is to apply while waiting to find a better alternative.
- Slug traps
Another trick is to trap the slugs to capture them more easily. The principle is simple: in the evening, simply place planks, tiles or cardboard in the garden. The feared gastropods come to take refuge there before dawn. All that remains is to lift the trap and grab the slugs. This method allows you to find even the smallest slugs.
First, it must be emphasized that the use of insecticides is strongly discouraged because they are harmful for plants but also for the environment. To eliminate slugs in a garden, there are several organic solutions.
- Wood ash
Chimney ash is rich in mineral salts, calcium, potash, silica. Just make a cordon around the plants to scare the slugs. The ashes are in addition a source of food for the plants but it is of course necessary to renew the operation after each shower.
Previously ground, the shells have a rather relative efficiency for the protection of plants.
Mulch and especially rough mulch made of pine needles, crushed ferns, sawdust or wood shavings is the alternative that is unanimously favored by gardeners.
- Sand, beer...
In the same vein, you can also spread a net of sand or put a saucer of beer mixed with a little water all around the plants to protect.
Finally, slugs do not like certain plants that keep them away from crops such as fennel, thyme or sage.
