Removing Cypress Knees Without Killing the Tree

Cut Knees at Ground Level

Cypress knees are root extensions for gas exchange. Roundup on knees kills the whole tree. Instead, cut knees flush with soil. New ones may appear elsewhere, but the cut ones won't regrow. Only remove the tree if knees are intolerable.
