Propagation
Sow fresh seed during spring and the seedlings may be used as rootstock for grafting or budding from winter to early spring. Plants may be transplanted during the dormant period. 

Air layer is carried out on the lower branches for small quantities.

General information on pruning Acer species 
The Maples normally do not require regular pruning apart from damaged, diseased or dead wood removal and this should be carried out from autumn to winter. 

Pruning in late winter or spring may result in bleeding of the sap and should be avoided. Remove reverted branches in variegated trees and clean up split bark with a sharp knife and allow natural healing.

Botanic information
Leaf: The palmately leaves have 5, 7 or 9 acuminate lobes and the margin is incised. During autumn the leaves turn red, orange or yellow and are less vibrant in warmer climates and change colour in late autumn. 
'Dissectum' leaves are finely serrated and lobed.
Note
The small greens to reddish buds appear in the base of the petiole.

Flower: The unisexual crateriform flowers have 5-sepals and 5-petals with 4-10 stamens and are arranged in a pendulous corymb or umbel that appears with new foliage during spring.

Fruit: The light brown twin samara is joined at the base and has membranous wings. They appear in small weeping clusters on the end of branches during autumn. The seeds are viable but the plant may be reproduced vegetatively.
