About this plant
This grows either as a single stemmed or multiple stemmed tree, although it can be grown as a shrubby plant. At its best it is likened in the grace of its growth habit to the Japanese maple (Acer palmatum). It flowers in April, the flowers are small and come from bright red calyces with white protruding stamens. They are followed by small red winged fruits. The broad leaves have around 9 shallow lobes but are otherwise somewhat rounded in shape. The autumn colour is variable, but exceptional in the right conditions. In sunny places it is red, but is gold in shady spots. The growth habit is sturdy and upright in sunshine. If grown in shade it is more delicate, with spreading, horizontally tiered branches. Although it is very tolerant of dry sites, it holds its foliage for longer if there is some moisture. It grows naturally on the banks of rivers and could be considered for this position if one has one's own watercourse or lake.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Winter
Winter · Planting
Prune to maintain the plant
Pruning is done in winter when the plant is dormant as otherwise it can 'bleed' badly when cut. Keep the plant looking attractive and healthy by removing dead branches, removing branches that cross or rub each other, and those which spoil its appearance.
The plant is encouraged to develop a pleasing shape by removing deviant or dead growth. It is much more likely to remain healthy if branches that rub, or can rub each other are removed since rubbed spots can be places where disease is introduced.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
