Yoshino Cherry – Roundup

Q: My Yoshino cherry is sending up new shoots from its roots. My landscaper has been spraying them with Roundup. He says that this will not kill the tree. I disagree. Who is correct?

A: Your landscaper is playing a dangerous game. Glyphosate (Roundup, KleenUp, etc) is translocated from shoots to other parts of the plant. There are many instances of glyphosate going from one tree to another when their roots graft to each other. A safer product to use is napthaleneacetate (Sucker Stopper).
