  Hi there! I was wondering if you had any insight on the American elm tree? Suppose I am trying to detangle the roots of the tree from an invasive plant (Japanese Knotweed), when would be the optimal time of year to do this? How long can elm tree roots be exposed? Is there a time constraint at all? I live in a 4 season climate.

  Answer

  Der monn7, good afternoon. The short answer to your question is I may not be able to assist you. There are too many variables that I would need to know. I do not know the size of the elm tree you are speaking about. In any case, if I were to attempt something as you state, I would try to do so on rainy/cloudy days to limit water stress and return the roots of the tree as quickly as possible to moistened soil. If the root mass is small enough, it can be dunked in a bucket of water or (otherwise) sprayed with a hose periodically to keep them moist. Good luck.
