I’m about to prune 2 of the maples I collected this year for the second time. These things are nuts with enough water, nutrition and space for roots (apparently anyway, still a newb remember). I’m following the hedging method of pruning a few times during the growing season to a general silhouette, letting grow, repeating and then I’ll wire and select branches after leaf fall so I can see all the options more clearly.
I hadn’t planned on pruning at all this year so soon after collection, but I have no need for a million foot long whips and no sense of where they’re heading til autumn. The tree dictates!
Like has been said and you agreed, I’d wait to see how the tree grows first. If it’s super crazy vigorous then a snip here and there wont hurt. If it’s a slower grower then choosing your cuts will be more vital.
45 squiddlies seems pretty good to me!
