Gardening Tip of the Day
If you grow fruit trees and find suckers sprouting from the rootstock of the trees, there are two ways to control them.
It is not uncommon for grafted fruit trees to produce this unwanted and unproductive growth. Several factors increase the occurrence of this problem and include drought stress, nutrient deficiency or damage to the main trunk.
Root suckers can be removed with a sharp pair of pruners. There is also a chemical control that uses the plant growth regulator NAA (naphthaleneactic acid). Apply following label directions when suckers are less than a foot tall in the spring. The control lasts for several months.
