My sumac tree is almost 2 yrs old. the tree has 7 healthy sucklings growing all around her. Can they kill or hurt my tree?
It isn't that they will kill your tree, as much as it will just steal nutrients, and make the tree grow much slower. It is best to remove these. This article will give you more information on the care of these trees: https://www.gardeningknowhow.com/ornamental/trees/sumac/sumac-tree-info.htm
