Plants are strongly outbreeding, self-fertilized seed usually grows poorly. ![]() In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by acid rain. Seed production is usually good, with heavy crops every 2 - 3 years. This also badly affects root development and wind resistance. Larger trees will check badly and hardly put on any growth for several years. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Annual increases of 30 - 40cm are not uncommon in some of the larger trees. ![]() The few trees of seedling origin tend to be fairly fast growing after a slow start.
