Overwintered green plants are the quickest way to produce a full crop. These are micro-propagated, virus-free plants thinned out in the greenhouse, hardened off in the open air and overwintered in the chiller. There are 60 plants in each plant culture tray. The best time to plant is in April. In optimum conditions, the plants can put out several roots, even in their first year, and can reach a height of up to 2 metres. They achieve their full yield in the year after they are planted. Autumn-fruiting varieties produce a satisfactory yield as early as the year in which they are planted, if they are planted early enough.
