Last week lightning stuck one of my pecan trees. It had grown into three large “trunks” (because I hadn’t properly pruned it to a single trunk when it was young), and the lightning strike separated one of the three from the tree. At the moment it’s still attached by a ribbon of bark and is still green and shows no signs of wilting. The fallen part has to be separated from the trunk and removed.
The separated bark seems quite wide to me, and the split off trunk is about a foot in diameter. I have no idea if the tree will be able to heal itself, but I want to give it the best shot for that. Should I just leave it alone for a while to get over the shock, or should I go ahead now and separate the fallen trunk from the rest of the tree?
