Question

Will copper sulfate kill trees?

Answer 1

Answer:

Copper sulphate is a poison often used to discourage tree roots from growing into vulnerable areas such as sewer lines. It can, however, kill a whole tree if it is properly applied. Although you may be able to kill a tree by putting copper sulfate on the ground around it, the sulphate is toxic to the water supply and the ground, so this technique should be avoided. Instead, use the copper sulphate to poison the tree more directly.
