. Agri-news. Agriculture. FOR IMMEDIATE RELEASE TOPPING TREES. A row of poplars which have had their growth controlled by topping. Topping, a method of controlling the growth of fast-growing trees, is not recommended except under very special circumstances, says Alberta Agriculture's tree specialist, Herman Oosterhuis. This practice of removing the tops of trees like poplars and willows to control their growth, leaves these trees deformed for the rest of their lifespan. The tree reacts to having its top removed by producing a mass of new sprouts each year, which unless removed, develop into branches. Topping also shortens the life of the tree because the large wound cannot usually be covered with a protective dressing. The result is that the wound does not heal over, leaving the tree subject to disease and lasting injury from decay. Topping used to be practised on farmstead shelterbelts either to control their height or with the mistaken idea that this type of pruning would cause the trees to brush out. Unless it is absolutely necessary to control the high trees because they are interferring with a power line or other overhead obstruction, topping is definitely not recommended. -30- /Jlberi AGRICULTURE 'hone (403) 427-2127 COMMUNICATIONS.
