I have a crabapple tree in my yard, about 50 feet from where the suckers are located. The only other trees in the yard are a pine and my neighbor has a swamp maple. Can anyone tell me if the suckers could be traveling 50 feet from the crabapple. There are no suckers within a 10-15 foot area of the crabapple. Any help is greatly appreciated as these things are driving me crazy! Thanks.
