Oh and by the way... The black plastic bag you were referring to in one of your previous posts how did you use it?
I´m asking this because around here, for some trees that are collected with long pivoting roots and almost no feeders (like some olive or pear trees for instance) a black plastic bag is placed upon them after trimming those long roots and having the tree potted, of course. Then the bag is only removed after these trees start backbudding again.
