Latest news - plan of action...
I never really got any replies to this post, but I am resurrecting it because I want to get your opinions on what to do next.
The ash tree that dropped its leaves due to anthracnose never really refoliated. It did maintain the remaining leaves, which were about half of its normal canopy. I made an extra effort to water the tree during the dry weather that we experienced in August and September, and I pruned off all of the dead branches that i could reach.
Here is my plan of action:
1. - Remove all of the mulch from around the base of the tree after the rest of the leaves have dropped, and dispose of it. I figure that the fungus has likely been over-wintering in the mulch and dead leaves. I will apply 2 - 3" of new hardwood mulch in its place.
2. - Apply fungicide to the trunk and branches this spring, before it leafs out.
Would it be beneficial to apply any kind of fertilizer this fall to help the root system? If so, what type of fertilizer would you recommend?
What do you all think? Does this sound like a reasonable plan? Additional suggestions/comments are welcome.
Thanks for the help!
