Part of the propagation unit, with a batch of Misty series cuttings ready to plant out. This glasshouse has under-floor heating and computer controlled heating and ventilation. After the cuttings are taken, from virus-free mother plants, they are dipped in rooting hormone and inserted into trays of blocking compost. The trays are then placed directly on the concrete floor and covered with polythene sheet. Rooting takes two weeks. The polythene is then removed to allow the cuttings to acclimatise prior to planting out.
