Seedlings, suckers, and other juvenile trees would be susceptible to damage if roots or leaves pick up Glyphosate through rain run-off or windborne spray.
Can a tree recover from Roundup?
The effect of glyphosate lasts over a period of years on trees. This is to say that the tree does not die off immediately, as it happens with weeds and grass. So, for as long as the tree is alive, continue taking care of it. There is a chance that it may recover and continue to grow normally.

Absorption of glyphosate through roots has been shown in several crop species, such as beets, barley, cotton, maize and rapeseed [13,15,16,17,18,19]. This exposure pathway is significant, because roots are the main intercept of glyphosate in field runoff.

Why do people hate Roundup so much?
Two reasons I guess. One, it’s an herbicide and some people wish that the entire world would garden organically. That’s a noble idea, but I just don’t believe that it’s going to happen.

Glyphosate is absorbed by the leaf’s other tissues. It poisons the biochemical machinery in the plant. It is translocated with the sugars from photosynthesis to actively growing tissues where it poisons them. Glyphosate materials cause little damage if they not do drift on to green tissues such as green leaves and young stems. If it is applied in the fall when there is little growth you probably will not see any symptoms from small amounts of drift.
