We have a 1.5 year old Mountain Ash tree in our front yard and we had a really long winter. At the bottom of the tree trunk it is spliting vertically. The cut is about 12 inches long and half an inch wide. We sprayed a tree sap type tar on the trunk as suggested by Home Depot Garden Center employees. Is this all we need to do to make sure that our new tree doesn't die?? Thanks so much!! |
