In the fall, all greenhouse structures need to be prepared for winter and the subsequent gardening season.

These actions are mandatory and the quality and quantity of the future harvest depends on them.

But in the spring, all that remains is to plant the plants and wait for the shoots.

Main works

Why is greenhouse cleaning so important? In favorable greenhouse conditions, harmful organisms, bacteria and weeds can develop, which, having survived the winter, will begin to attack the young shoots of your crops.

The last processing of the greenhouse before the onset of cold weather is divided into two stages:

  • putting in order the soil;
  • disinfection and repair of the structure itself.

Treatment of beds

It is divided into several stages:

  • Spring-cleaning. Removal of all parts (underground and aboveground) of the remaining plants. Harvesting all fruits from the ground.
  • Removing the topsoil and replacing it with a new one.
  • Disinfection of soil. Digging and warming up.
  • Disinfection. The most popular methods are treatment with urea or fumigation with sulfur and other substances. Experts advise disinfecting even if your plants are not sick.
