How does pruning help in making the hedge dense?

  • It induces the differentiation of new shoots from the rootstock

  • It frees axillary buds from apical dominance

  • The apical shoot grows faster after pruning

  • The apical shoot grows faster after pruning


B.

It frees axillary buds from apical dominance

Pruning helps in making the hedge dense as it frees the axillary buds from apical dominance. In fact, the apicies of the plant axis (e.g. Shoot apex) has the highest concentration of auxin which suppresses the axillary buds while promotes the growth of apical bud. When the shoot apex is cut down through pruning, the axillary buds grow and the hedge becomes dense.
