Hello everyone. I started an air layer about 10 weeks ago on an acer palmatum dissectum. It has about 10 large roots i can see growing through the plastic. They are about 1/16" thick. The are brownish red in color with white tips on them. This is my first air layer and I am wondering how long i should let it stay? Until middle of summer, or sooner, later? I learned the roots would start off white and turn red, then time to take off of parent plant, but not sure if this tree is different. Thanks in advance.
