Place the tree where it will receive morning or evening sun but will not be in direct sunlight, especially at the height of summer. It is a very hardy species, but is best protected when temperatures are likely to fall below -10C for prolonged periods. Keep in cool greenhouse for these periods.


Water regularly keep soil moist not wet as root tend to suffer easily from root rot. Ensure soil is well drained. Water well in early morning or late afternoon to prevent the soil from drying out. Do not water plant during the hottest part of the day best in the early hours of the morning, when leafs.


Feed bimonthly during the growing season. Use a high nitrogen fertiliser. during spring and a low nitrogen fertiliser the rest of the year. Do not feed during peak summer.

Leaf and Branch Pruning:

Pinch back to 2 leafs once 4 to 5 leaf nodes have grown. To develop fine branches and avoid long inter-nodes, pinch back new growth during the growing season. Pinch back new shoots through out the growing season.

Re-potting & Growing Medium:

Repot younger trees every 2-3 year, trees older than 10 years only when pot bound. Repot in spring, shortening root by no more than a third of their length. Remove dead and damaged roots to avoid root rot. 1 Part Akadama and 1 Part Pumice and 1 Part Leaf Mould or Well Mulched Bark


Maples are usually shaped by pinching and pruning. Wire sparingly and with care, in spring. Check wire frequently and remove after a few months.
