Effects of Pruning on Root and Shoot Growth of Ilex crenata ‘Compacta’

In 2 experiments, shoot pruning at potting reduced root growth of transplanted rooted cuttings (liners). However, tip pruning of plants increased root growth compared to severe pruning (50% of shoots) and increased shoot numbers compared to nonpruned plants. In experiment 1 severe shoot pruning of transplanted liners in September resulted in increased shoot numbers compared to nonpruned plants, while in a second experiment, severe shoot pruning in May had no effect on shoot numbers.
