    large split in Maple, is it appropriate for support?

    Try melatonin. No need to remove a tree that someone else knows how to manage.

    Possible dieing maple? Need expert opinion.

    Post a pic. 20 years of SGR work; seldom seen a case where tree removal was the best option. Sounds crazy. 16 years later this tree's doing well.

    Diseased oaks?

    When you say infected trees do not recover, does that still allow for a kind of standoff, where the tree grows enough new tissue to compensate for the lost tissue? So in landscape tree terms, it could be quite reasonable to retain?

    First, those cuts look like removal cuts. A reduction cut would be further out. Since there is no collar on codoms, what is the advantage of cutting that far back? ATH and VB are right on this. P.S. Ignore the 1/3 rule. Second, different general have different architecture. Removal cuts on...

    Preservation vs Condemnation

    Definitely woody matter belongs on the surface. like anything you cannot break up with your fingers. Think about what happens in nature. What makes you think there is extensive decay? Those types of wounds often have no or very little decay, and the woundwood can more than make up for it in...

    Preservation vs Condemnation

    Diagnose first. The big infections seem old--see the woundwood on the edges? Bleeding lesions should be cleaned and heated. phosphite drench. No reason to reduce load (yet)--no strength loss observable. I hope the cedar mulch was not added to the soil. "I can’t help but notice the large...
