Abstract:
Results of pruning-experiments showed no significant differences in winter flower production between selective pruning and hedging. Winter production was related to the degree of the plant cut-back during the spring. Severe removal of the plant canopy resulted in decreased winter production of flowers. Delay in autumn cut-back decreased total winter yield, but mid-winter production was increased. The decline in winter flower production, following early summer cut-back, was partially restored by continuous lateral bud removal (de-shooting) during the summer. Flowering was greatly hampered by defoliation. © 1981.
