Growing Japanese Maples in containers has greatly increased in popularity in recent years. Many of the cultivars are ideal subjects for pots because of their tolerance, adaptability, shallow fibrous root systems, minimal feeding needs, an enormous choice of shapes, sizes, and colours.
With proper but not over-demanding care, Japanese maples may be grown in containers for several years without needing to be repotted or to have their roots pruned. Dwarf maples in ornamental urns are well suited to small patios and can be used singly or in small groupings. Where larger containers can be utilised, the range of choices increase greatly; the larger growing dissectums and the upright cultivars do extremely well. The choice of form, colour, leaf texture and winter branching is wide-ranging.
The full-sized species and cultivars are easily grown in tubs or large, permanent containers. Occasional directive shaping and pruning is not a demanding chore, attention possibly once or twice in a season being all that is required.
**TWO IMPORTANT REQUIREMENTS MUST BE MET IN ALL CONTAINER PLANTING**
First, the planting mixture must be open enough to allow good drainage and aeration and thus avoid becoming waterlogged. Second, the containers must be give faithfull attention and not neglected for long periods of time during the growing season.
