There is definitely some confusion going on as to what WP meant by hedging. I read exhaustively on Walter's Blog and IBC what you were talking to him about concerning this topic Neli and it seems that there is a simple misunderstanding concerning the tools and method he uses to prune his trees. He says "hedge" when talking about doing the first cut back of the summer, but he is NOT just grabbing the electric trimmers and arbitrarily chopping the trees into a shape! He IS pruning each branch back to create a specific outline for the tree, removing extended growth and that promotes profuse buds and shorter internodes. In the fall he goes back and fine tunes the tree- removing branch tips, removing unwanted branches... The point of his technique is merely to say you let the tree grow, cut it back, let it grow, cut it back... He is not pinching out the growth tips in early Spring on every branch like many people seem to recommend.
It doesn't matter if you do your hedging with large shears and just maul your tree into the mushroom shape you want, or if you go in and finely cut every branch to produce the desired outline. You are splitting hairs and missing the point. The tree will be more vigorous, more healthy and produce more growth, more new buds, more fine ramification using the hedging method (again, whether you finely cut each individual shoot with scissors, or whether you use the sword shears like Walter uses) than it would if you pop off every little growth tip in early Spring, rob the tree of all of it's stored energy and let it struggle through the growing season.
Which way you go may vary depending on the desired result for a specific tree. If you have a well established, ramified masterpiece that is in need of very little development and you just want to keep it in shape- pinching the tips is probably fine! (Though it likely will eventually weaken the tree, and it would take about 24 hours of straight work with tweezers and a magnifying glass to do it on a tree like the ones Smoke posted pics of!) But- like 99.9999% of the trees in America and Europe- most of us have young trees that are in need of more growth and development and his method makes a lot more sense than the standard "pinching" technique so many people have read about and try to apply to even very young trees.
He did NOT develop this method because he was too lazy or had too many trees to prune them properly as you seem to continue to imply. Nor would I say WP really invented it himself- more he discovered it is the superior method by comparing it side by side against similar trees using different methods.
I am not trying to start a fight or say one person's method is the only way and everyone else is wrong... Just that the reasons I see you consistently post for why hedging shouldn't be done make it clear you are kind of missing the point of what it is supposed to accomplish, and in the end you clearly AGREE with the stated goals of the hedging method, just not the term "hedging" or the used of large hedge pruners?
Not trying to disagree with you either M5- yours is a gorgeous tree, no doubt! I am not one to tell you to change anything you are doing, as it is obviously producing some great results! Just saying the word "hedging" seems to be misunderstood by many and I have seen fantastic results from using WP's technique, I know it works for people who are trying to get the best results they can from a Maple- or probably most any Broad Leaf tree.
