Root and shoot pruning in root-balled Acer platanoides L.: effects of establishment and shoot architecture.
Various combinations of root and shoot pruning treatments were applied to semi-mature, root-balled trees of Acer platanoides prior to planting in an experimental plot at the Bush Estate, near Edinburgh, UK. After 3 years' observation and measurement, the treatments had little effect on survival or girth. However, performance as gauged by annual shoot increments was significantly improved by shoot pruning in the 2nd and 3rd years after transplanting. The shoot pruned trees recovered from the effects of transplanting to a much greater extent and there was a noticeable effect on the relative balance between apical and lateral increments.
