Acer palmatum 'Red Emperor'

A small deciduous tree growing approximately 3m tall by 3m wide.

Palmate, purple leaves that turn bright red in autumn and dark red in summer. Winged seeds are produced in late summer.

Best in partial to full shade. These trees can take full sun but foliage may get scorched.

Always choose healthy well-grown plants and plant after autumn rains. Before planting, ensure the root ball is saturated and remove the planter bag or pot with minimal root disturbance. Trim any broken roots or branches and plant at the same level as in the container. Dig a hole twice the diameter of the root ball. Make sure plants are watered well until established if planting in a drier period. Plant with some general slow-release fertiliser and every spring apply an organic-based fertiliser, such as blood and bone, at a handful per square metre. For windy positions staking may be required. Planting success is often improved on clay soils by adding extra topsoil and forming raised beds. Incorporate coarse sand, bark, peat, compost or other organic material to improve soil structure.

This plant is easy to maintain and needs little pruning except for the odd removal of damaged growth. Make sure not to plant in windy situations as the edges of the leaves will get wind burnt.

Generally pest and disease-free but could get mildew in humid conditions.

Great planted with woodland perennials and around streams or ponds if the soil is not too wet.
