|We need to trim some big limbs off some large pecan trees to build a carport where the limbs are overhanging. What do we need to put on the cuts to prevent damage to the trees. Is there a substance that we can use without buying expensive wound paints?|
|No, most tree specialists now recommend against painting pruning cuts unless there is a specific insect or disease related reason for doing so. Make sure and make your cuts just outside the natural, raised ring of bark where the branch attaches to a larger limb or to the trunk. Don't cut flush with the trunk (too close) or leave a stub (too far out).
Regarding your second question. Orange shellac makes a decent replacement for commercial pruning wound paints.
