Wiring down branches in the spring was a mistake, every branch I moved died.
Working the tree "a little more" too soon after major work was a mistake. The branches died, then the rest of the tree followed suit by the end of summer.
I have since learned that these DAS can take this kind of chop back, but then they need at least a couple of years to recover enough to do any more work. "Healthy growth" is not the same as "fully recovered and vigorous" I probably would have been OK if had done what I said I was going to do in post #18
I would have done better to have followed more of the advice I was given. But I learned a lot by comparing what I did with what I should have done.
