Pruning your shrubs can give your entire landscape an amazing aesthetic appeal. Ideally, there are typically two types of landscapers when it comes to pruning shrubbery; those who prune timidly from fear of damaging their bushes and those who prune aggressively to come up with perfectly shaped shrubs. However, to achieve the best outcome when pruning your bushes, trimming about one-third of the good wood is ideal.
If you prune more than this, you risk exposing your shrubbery to excessive damage, which could stunt its growth. Prune less than this, and you might not do much to improve the appeal of your shrub.
Read on to learn about the one-third rule:
Why The One-Third Rule?
Moderate pruning is pivotal when it comes to stimulating vital growth. Plants typically live in a balance between the below-ground and above-ground parts. Once the plant loses a number of stems through pruning, it tries to gain back the balance by pushing forth new growth. This regrowth is essential, especially in moderation, since it allows the plant to heal as well as simulates growth from dormant buds.
If your shrubbery loses too much leafy growth, it goes into panic mode. This can be shown by the appearance of water sprouts or suckers, which can leave your shrubs ragged looking. Even worse, this suckering can go on for a long time, making landscape maintenance tough.
Use the Rule on Established Plants
The one-third rule is ideal for your fully established shrubbery- plants that have overcome their transplant shock. If you have newly planted shrubs, give them a grace period of one or two seasons before pruning them to ensure that their root systems become established enough.
Use the rule on small ornamental trees and shrubs. As for larger shade trees, limit pruning to at most a quarter of the total branches. While growth on shade trees is stimulated into new growth through assertive pruning, its pruning shouldn’t be as vigorous as that of multi-stemmed shrubs. Pruning the trees often is vital since it reduces the chances of wind damage.
When Might The one-third Rule Not Be Enough?
If you neglect your shrubbery for too long, it might overgrow and get out of control. Normal pruning might not suffice. For such shrubs, rejuvenation pruning (a severe form of pruning) might work. While rejuvenation pruning will leave the shrub looking unattractive for a while, it allows it to reform itself into a better shape.
As long as you show your shrubs love, they will light up your landscape. Pruning ensures that you can shape your shrubs to fit right into your ideal landscape design. Consider using the one-third pruning rule to improve the appeal of your landscape.
