The Forgotten(?) Art of Pollarding Trees

Topping trees to encourage growth has a bad name among tree fanciers like me. The conventional wisdom that it shortens the life of a shade tree has a lot of merit, but then again, don't we prune trees constantly?

As I do most of my heavy pruning in winter, especially late winter, I wanted to talk about a time-honored way of harvesting firewood without cutting down an entire tree. I've begun to practice it in my own woodlot. 

The photo above, from the Wikipedia entry on pollarding, shows a beech in Epping Forest, England. In the old world, where ancient forests long vanished, second-growth trees needed careful management to avoid vanishing. Legal rights to pollard a certain amount of wood were granted to locals.

Pollarding provides a safe and sustainable method, and carefully pollarded trees can live a very long time. The beech above has not been cut in a many decades, whereas a regularly pollarded tree will not produce the huge side branches shown.  For those working with willow for crafts, pollarding leads to a nigh-endless supply of material.

I use pollarding on our fence-lines, where gums, poplars, and other shade trees occur. Some I cut down to a stub 3  or 4 feet in height. The trunks get cut into small rounds for the woodstove, after seasoning a  year. The branches and twig I drag away to make brush-piles at the edge of the woods, to shelter wildlife. Sometimes I pollard very long stems to make beanpoles.

Pines, of course, cannot be pollarded, and once cut, do not return. I knew that but didn't know it as an ancient threat by Croesus from the Persian/Greek wars. Thanks, Herodotus.

If you burn wood in  your fire-pit, fireplace, or wood stove but live where you don't have a ready supply of large logs, you may want to begin pollarding trees. You might find it most handy for trees under power-lines as well. Keeping them short avoids the sort of awful slash/pruning power-companies often do to protect infrastructure. Pollarding provides a way to keep a tree like that gracefully shaped.
