how protect cut tree limbs
Hi. I had to chainsaw a feww branches recently because of a brutal ice storm this past winter (Massachusetts). As a result, the area where the branches have been cut are exposed and I am worries that disease or insects will find those areas inviting. I found a chemical based spray at Home Depot which basically seals the cut areas and protects it; however it is chemical based and I am trying to stay away from that stuff.
I would like to learn of reccomendations for a natural (or mostly natural) way to protect trees with cut branches.
