On a recent discussion on witch's brooms and there problems, Whis4ey recommended using a micoroyza fungi to help the root development. I took his advice and added this to my brooms. I just had to dig up a couple of these plants and I can't believe the network of white roots, after just 6 weeks. My question, would this be beneficial to add to all my maples? It is a bit expensive, but my maples are my babies, and what won't we do for our babies?
