Cypress Tree Knees

Mr. Gill,

I have numerous knees in my yard from 2 cypress trees. Most of them have been cut to ground level by my lawn mower when mowing the lawn. However, they make it extremely difficult to mow the lawn.

Is there anything that can be done to remove them chemically without damaging the actual tree? Some of the smaller knees have been hammered below the ground level by me using a large hammer or maul.

Any comments or suggestions please!!

Thanks, Larry L.

The most common way to deal with the knees is to cut them off. Dig down around a knee a few inches deep. Use a pruning saw (check at your local nurseries) to cut the knee off an inch or two below the soil surface. This will not hurt the tree. The hammer or maul would also work, but is more damaging to the roots. There are no chemical solutions for this issue.
