hardening: After two months in the greenhouse for rooting cuttings are sorted and transplanted in the greenhouse for hardening. This greenhouse is designed to fit young rooted cuttings to environmental conditions outside. In this greenhouse is maintaining a growth temperature between 20 and 25C degrees and the humidity is reduced from 50 to 70%.
Cuttings are transplanted into pots or bags of 0.5 to 3 liters containing a homogeneous mixture disinfected before transplantation. Fertilizer is added to the bottom (NPK) or slow-release fertilizer to the mixture prepared. In the modern nursery cuttings were transplanted into pots of 7 x 7 x 9 cm or 9 x 9 x 10 cm using peat as substrate.

transplantation can be done manually or mechanically. The first days after transplantation, the seedlings are regularly irrigated by sprinklers, watering or drip.
