Thanks everyone.
jds,
-I pinched the terminal bud a few weeks after starting the air layer, as the branch kept growing very fast. It grew two more shoots and I removed them a few days ago. I had thought about trimming about 12" off the main stem but I didn't know how the plant would react. I like your idea of snipping the top in the spring. Thanks
Frank A,
-Glad to hear, buddy!!
