Q.purple leaf sand cherry removal
I got tired of the care needed and the overgrowth of my tree and decided to take it out. If any part of the root is left behind will it send up new tree growth and what is the best way to get rid of it totally?

If you aren't removing the main truck/stem below ground then it will re-sprout. Your options are to cover it with a tarp and some stones to block all sunlight. This may take an entire season to be effective. The roots can be left in place to decompose. A quicker solution is to wait until the sand cherry leafs out completely. At this point, cut it down and immediately apply a thin layer of herbicide such as triclopyr or glyphosate concentrate to the cut stumps. Using a small paintbrush is convenient.
