Abstract:
Many kinds of cuttings which root easily present a survival problem during the subsequent winter, for when potted or flatted after tooting they go into a dormancy from which they never recover. In an effort to avert this loss of material a method of handling these difficult cuttings without disturbing them was tried. Plastic flats were filled with rooting medium suitable for the material being tested, the cuttings inserted and the units placed in the propagating case. When rooted they were left in the flats, given a light liquid feeding, and hardened off. In November the units were transferred to cold storage and in March were returned to the greenhouse where new growth soon appeared.

Enkianthus cernuus rubens and E. perulatus are two subjects that have shown very poor winter survival. This slide shows 30 rooted cuttings of E. cernuus rubens which were left undisturbed before overwintering, all of them survived. Twenty-four cuttings of E. perulatus were treated similarly and of them 21
