The benefit of the clamp is the ability to use it on older trees. No cutting tile. Great idea!!
Hah! Thats an awesome idea, very nice.
Nice idea re: hose clamp. What time of year do you perform this?
I've got a maple with some reverse taper on the bottom couple of inches. I'm thinking about trying this method - applying the clamp above the reverse taper, and burying up to the clamp to force out new roots.
Did you do this in the spring, or in the fall?
I know d trees start more agressive root growth in the fall to get ready for winter. I would think you wouldnt want to put it too tight to start because the clamp would scrape the bark off as it tightens. Maybe put some raffia on it before making it real tight. I think it would be safe to do it anytime. Your not really doing anything to the tree. My question is how far above the clamp, or wire would you have your soils, and does one type of soil or another work better for the "top coat"?
