Soil disinfestation:

The soil of our garden is naturally infested with insects, weed seeds, mushroom spores; the cultivation of plants in the garden can be seriously compromised by the development of one or more of these pests and weeds. For this reason, before sowing any vegetables, we try to clean up the substrate, so that afterwards it is not necessary to intervene with fungicides, insecticides or continuous interventions to remove weeds. As regards animal pests, special chemical products are found on the market, which are spread on the ground before processing, so as to mix them well with the substrate. They often function as real baits, and kill insects that also ingest small amounts. To clean the soil in a deeper and more complete way, especially if you have a flowerbed that has been heavily exploited over the years, you can practice solarization: you work the soil and cover it with dark plastic film, possibly during the hottest months; the solar rays heat the plastic film, and consequently also the ground below. The high temperatures thus reached go to completely disinfest the soil, destroying spores, larvae, small insects and making small weed seeds sterile. This practice generally works only if the ground remains covered, fixing the sheet at the edges with metal jumpers or stones, or simply with small wooden laths, for at least 35-45 days. The solarization must therefore be performed in rotation on the beds at rest.
