The beds are prepared in advance, one month before disembarkation. After digging, the soil is fed with complex mineral fertilizers and disinfected with a copper-containing solution. For top dressing, it is better to use wood ash, humus or rotted compost. Fertilizing the soil with fresh manure is not recommended, as the plant will build up a green mass and make the bulb loose.
