clear up the leftover from a tree
After a year of waiting for budget, my home owner association finally promise to remove a poplar tree a foot away from my backyard fence. The workers will apply round-up too. My question is whether I need to dig out all the roots from the tree in my garden. How soon can they become rotten? Can stump remover speed up the rotten process? Or should I simply leave them alone because they won't compete with other plants any more?
I appreciate anybody can share your valuable knowledge in this regard. Thanks for your time.
