I typically see just one leader on pines being developed. Is it best to only allow one leader/sacrifice branch to run or can multiple be used at once? For example, if top leader is healing a chop scar, is it bad to have a strong low sacrifice branch to pump up the trunk.
Also, leaders tend to be long single straight stems. At what point are the other buds removed from the leader to allow a single bud to keep pushing skyward?
