FAQ

I have thin branches growing from the base of my tree since spring. Should I remove them with pruning shears to improve the tree's appearance, and if so, how can I prune them to prevent them from growing back? The branches are no thicker than half an inch.

Certain species of trees, such as crab-apple, sprout profusely (sucker) from the root stock. This commonly happens on grafted plants so the shoots and foliage on suckers may appear different than the rest of the tree. You can simply prune these off at the junction at the base of the plant anytime they appear. They will grow back and often increase in number with time. Pruning these suckers are just a normal part of maintenance of such trees. There is a product called Sucker-Stopper RTU that contains the active ingredient Ethyl 1-napthaleneacetate, which is a plant growth regulator that suppresses sprout formation. It is sprayed on the base of the cut sprouts immediately after pruning. Sucker Stopper suppresses sprout growth for a year after application. It is not readily available in garden centers, but you may be able to buy it online if you search for Monterey Sucker-Stopper RTU.
