Slugs often appear in a greenhouse and cause significant damage to the crop, especially in warm and humid weather. They come out at night and quickly spoil leaves and seedlings. But there is a simple way that helps keep them away without chemicals or extra costs.
The essence of the life hack is to make a dry protective strip around the plants. Slugs cannot move normally on rough and dry surfaces. They need moisture, and such materials literally prevent them from crawling and “dry” quickly.
The most accessible things are suitable for the barrier: ash, sand, crushed eggshells or pine needles. They are simply poured around the beds or directly around the plants in a layer of 5–10 centimeters. Slugs do not like such areas and avoid them.
It is important to remember: the barrier must be dry. After watering or rain it is better to renew it, otherwise the effect is reduced. Many summer residents mix several materials at once – this way the protection lasts longer.
Additional benefit: good for the soil. The ash slightly fertilizes the soil, and the shell makes it looser. In this case, no harmful substances remain in the soil.
If you add regular ventilation and do not overwater the plants, slugs practically stop appearing. Experienced summer residents know that one dry barrier can protect the greenhouse all season without unnecessary hassle.
