Autres usages

• Wood - used in construction [272].
• It is also used for fuel [272].

Culture

• Of easy cultivation, it succeeds in most soils preferring a good moist well-drained soil on the acid side and partial shade [11, 182].
• Pousse bien dans les sols très argileux .
• 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 .
• Requires some shelter in the cooler areas of Britain and protection from cold drying winds [1].
• Grows well with rhododendrons .
• Most maples are bad companion plants, inhibiting the growth of nearby plants [18, 20].

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 [80, 113].
• 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 June or July .
• 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 .
• Only strong-growing cultivars succeed from cuttings, plants of the dissected or variegated cultivars will rarely grow into good plants .
