I'm new to the whole bonsai experience, and I haven't ever air layered something, but I hear that it is a very quick and effective way of getting a tree with a desirable sized trunk trunk. My girlfriend's parents house has a number of bald cypress trees in the back and I was planning on trying to air layer some as I love the look of bald cypress trees. I understand the basic process, but are there any precautions or specifics that I should look for in my specimen? Can I get any additional information on the best way to do this specifically to a cypress? Is spring the best time to start? Thanks!
