Pollard Christmas Trees

At High Reach Farm in North Danville, Vermont, my friend Steve Parker has been growing Christmas trees via pollarding (leaving green branches at the bottom) for many decades, refining his techniques. He uses no chemicals, and mostly stays out of the trees (e.g., no mowing) during nesting season. So some people get Christmas trees with a nest included. He does lots (and lots) of pruning, and in the Fall leaves the brush in piles along the road-paths through the trees for pickup by people who make wreathes and similar things requiring brush. He gives it to them - part of his "gift economy" nature.
A few years after a tree has been harvested, there will be multiple candidates for "next tree". Steve will leave a couple of these to develop, knowing that some will not make it, due to conditions beyond his control. This method speeds up the process of growing a tree. The existing tree will generate a havestable tree a few years quicker than growing one from a seedling - and no need for herbicides (used to keep down competing plants).

There are farms doing that out here on the west coast too. I found this article from 1998 that tells how to do this ‘stump culture’ and that there are farms that have been producing a Xmas tree every 5 years for 60 years by this method.

I have thought about this in an urban context.
I think chickens would really love living underneath these trees.
