jquast- Jeff, regarding Cork Oaks, I have a number of newly repotted Cork Oaks; they were all root pruned and potted in Jan-March. The trees that had no foliage Burst Buds within a month, the ones with branches and foliage did not. They did lag and put on some Terminal Buds only. I then proceeded to defoliate and - viola! Buds all over. I trust your advise and am trying to decide if this Bud burst is seasonal timing or hormonal response. I am now planning on defoliating a larger Oak (now in April) in order to get Bud Burst as well. Do you think I should remove leaves or all leaves AND branches?
