My neighbor and I have hackberry trees. His tree has gull leaf desease and the leaves fall into my yard all summer and fall. I guess my tree will get it too. I don’t think this will kill the trees, but I want to compost the leaves if I can. I avoid composting all the leaves in my yard since the gull leaf leaves are mixed throughout the other tree leaves around that land in my yard. Hate to be missing composting all the leaves if it is ok to compost the gull leaf ones! I read some leaf desease are ok to compost, but could not find out about gull leaf desease and composting. Can I compost the gull leaf deseased leaves from the hackberry tree? Thank you very much.
