Removal Of Yucca Trees

Question

After cutting down and putting Roundup or similar into drilled holes how long before you can consider tree to be dead?

Answer 1

Once the stumps are dead, they should easily give way and be easy to cut out. The time involved depends on the size of the stump, type of tree, amount of moisture, time of year, and other environmental factors. However, a glyphosate label reported the product would kill the stump in two to four weeks.
