With us moving to our new location and transferring trees. I decided to remove some of our trees from inventory as they were not progressing they way we wished. Never being one to waste, I decided to experiment with these to see what would happen.
The experiment was to take rooting hormone with a concentration of 3% and apply it to a variety of different trees. A 3% concentration has been (as I understand it) reserved for hard to root cuttings. Well, we decided to use it on not only these, but on japanese maples, hornbeam, dawn redwoods, and cork bark elms trees that aren't so hard to root. We didn't use the hormone for cuttings. Instead we used it on trees that had bad nebari to see if we could enhance root growth faster in these deficient places by scoring and dusting in areas that we would like to enhance.
This was done 18 days ago and in the last 5 days an incredible flush of growth has come up from each spot that was dusted, for the exception of the pines which I would expect. Also no growth from the redwoods which pop roots if you look at them and smile. This was surprising and unexpected with what happened to the rest.
I am anxious to pull back the soil (these trees are in the ground) and inspect the roots but will wait a bit longer as not to disturb the fine growth. What I am really wondering is, did the hormone actually send roots out and the shoots(suckers) are a bi-product of that or did the hormone trigger latent buds and there are actually no roots at all?
