Japanese Maple cracking/dying
The heat in Ok last year combined with drought caused deep cracks in about 1/3 of my Japanese maple branches. It appeared to bounce back this spring, then about a month ago the leaves on those brances are now dying. Should I Cut back these branches to the non-damaged areas, paint them or just take my chances and monitor? This tree is about 8 years old and on the NE side of my home in a nice shady area that gets full mid day sun for a couple of hours. Thanks for advise.
