Cultivation Details
Acer platanoides is a very cold-hardy plant, able to tolerate temperatures down to around -35°c when dormant[1]. Of easy cultivation, it prefers a good moist well-drained soil but thrives in any soil[2, 3]. Grows well in heavy clay soils. Prefers a sunny position but tolerates some shade[2, 1]. One report says that plants tolerate chalky soils[1], but another says that plants can develop chlorosis as a result of iron deficiency when they are grown in alkaline soils. Trees are very tolerant of atmospheric pollution[4]. The best sap production comes from cold-winter areas with continental climates. The tree trunk is tapped in the early spring, the sap flowing better on warm sunny days following a frost. There are many named forms that have been selected for their ornamental value[2]. Norway maple is a bad companion plant, inhibiting the growth of nearby plants[5, 6]. The leaves are seldom eaten or defaced by insects because the tree contains a sharp milky juice that they dislike[7]. Trees take 30 years to produce seed[8].
Propagation
Seed - best sown as soon as it is ripe in a cold frame, it usually germinates in the following spring. Pre-soak stored seed for 24 hours and then stratify for 2 - 4 months at 1 - 8°c. It can be slow to germinate. The seed can be harvested 'green' (when it has fully developed but before it has dried and produced any germination inhibitors) and sown immediately. It should germinate in late winter. If the seed is harvested too soon it will produce very weak plants or no plants at all[9, 10]. When large enough to handle, prick the seedlings out into individual pots and grow them on until they are 20cm or more tall before planting them out in their permanent positions. Layering, which takes about 12 months, is successful with most species in this genus. Cuttings of young shoots in early summer . The cuttings should have 2 - 3 pairs of leaves, plus one pair of buds at the base. Remove a very thin slice of bark at the base of the cutting, rooting is improved if a rooting hormone is used. The rooted cuttings must show new growth during the summer before being potted up otherwise they are unlikely to survive the winter. Cultivars can be budded onto rootstocks of the species. Any grafting is best carried out in September rather than late winter.
