Before winter, you need to clean the nursery and the field. It is necessary to carefully wash the racks, walls, floor and containers in the nursery. It is now, in advance, before the start of the next season, that all damage to the equipment or accessories should be found and repaired.

Before the winter season, all the pallets in the field should be thoroughly cleaned of snail feces and removed. Any dead snails should be picked up from the ground, the soil dug over again or plowed. This is done to control the pest - the cruciferous flea which feeds on perko.
