2. How to prune Barberry or Berberis

Pruning a barberry bush is necessary to control its size, shape, and to promote healthy growth. It is advisable to do it during the bush’s dormant period, generally in winter.

Steps for pruning a barberry bush:

• Use a pair of pruning shears or a saw to cut the thick, woody stems of the shrub down to a desired height. It is advisable to leave at least 2-3 buds (shoots) above the root bud (shoot) to promote new growth.

• Remove all stems and branches that are dry, damaged, or diseased.

• Cut back branches that are growing into the bush to promote denser, more compact growth.

• Remove downward-growing branches to improve the appearance and health of the shrub.

• Cut branches that are growing at odd angles or that are tangled with other branches.

• Use pruning shears to clear branches of leaves and twigs.

• Lastly, scrape the bark off freshly pruned branches to avoid infection.

It is important to note that pruning can be very stressful on the shrub, so it is recommended not to prune too much in one sitting.

With this pruning, it is possible to renew the bush and improve its appearance.

4.4 Training pruning

Training pruning is carried out in the first years of the bush’s life, to give it a proper shape and control its size. The main stems should be selected and the lateral ones removed to guide the growth of the bush. It is important to carry out this pruning in spring, before the start of vegetative growth.

4.5 Cleaning pruning
