It does not tolerate wet or over-compacted soil.<ref name=ncsi/> [[Plant propagation|Propagation]] is similar to that required for ''Acer griseum'' and the number of viable seeds is likewise very small.<ref name=gelderen/>
In [[Great Britain]], the largest specimens are up to {{convert|13|m|ft|0|abbr=on}} tall, and {{convert|60|cm|0|abbr=on}} trunk diameter (Tree Register of the British Isles).
