Sycamore (Acer pseudoplatanus)

Of easy cultivation, it prefers a good moist well-drained soil and a sunny position[11, 17], but tolerates most conditions including poor soils and some shade[13, 17, 200]. Grows well in heavy clay soils. Chlorosis can sometimes develop as a result of iron deficiency when the plants are grown in alkaline soils, but in general maples are not fussy as to soil pH. Dislikes wet soils[115]. Grows better in the cooler areas of the country[11]. Very wind-resistant, tolerating maritime exposure though it is often wind and salt pruned in very exposed areas[4, 11, 17]. A fairly aggressive tree, it self-sows freely and inhibits the growth of nearby plants[18, 20]. It is often one of the first trees to colonize open land. It is fast growing and establishes rapidly. It can supplant native trees, at least in the short-term, though recent evidence suggests that in the long term it does not usually become the dominant tree in British woodlands and it is often recommended for planting in broad-leaved woods by the Forestry Commission, especially in windy areas[K]. Plants are subject to sooty bark disease – this is not fatal and occurs most often in years that follow hot summers[11]. There are many named forms that have been selected for their ornamental value[200]. Trees take 25 years to come into bearing from seed[98].
