How to Grow Copperleaf
Acalypha wilkesiana
Copperleaf thrives in full sun with well-drained, fertile soil. It is a fast-growing tropical foliage shrub grown for its spectacular copper, red, and bronze mottled leaves. In frost-free climates (zones 10-11) it grows as a permanent evergreen shrub; elsewhere treat as a summer annual or container plant and bring indoors before frost. Water regularly but avoid waterlogging, feed monthly during the growing season, and prune hard in spring to keep the plant bushy and vivid.
Yearly Lifecycle
Care Essentials
Feed monthly during the growing season (spring through summer) with a balanced liquid fertiliser. Reduce or stop feeding in autumn and winter.
Watch For
- Spider mites (especially in dry indoor conditions)
- Mealybugs
- Whitefly
- Root rot from overwatering or poor drainage
Pet Safety
Care Requirements
Light
Full sun for best leaf colour
Thrives in full sun (6+ hours direct light daily). Partial shade is tolerated but leaf colour becomes duller and greener. In very hot climates, light afternoon shade prevents scorch.
Watering
Regular watering; avoid waterlogging
Water regularly to keep soil evenly moist, especially during hot weather. Allow the top few centimetres to dry slightly between waterings. Never let the plant sit in standing water — root rot is the primary risk.
Fertilizing
Monthly balanced feed during growing season
Apply a balanced liquid fertiliser monthly from spring through summer. Reduce feeding in autumn and stop entirely in winter when growth slows.
Pruning
Hard prune in spring; pinch tips regularly
Cut back hard (up to half) in spring to encourage a compact, bushy habit and vivid new growth. Pinch out growing tips throughout the season to maintain fullness and remove insignificant flower spikes as they appear.
Spacing
90-120 cm apart
Space plants 90-120 cm apart for good air circulation. Container plants can be kept more compact with regular tip-pruning.
Growing Tips
Maximise leaf colour with full sun
Leaf colour is most intense in full sun. Partial shade is tolerated but produces greener, less vivid foliage. In very hot climates, light afternoon shade prevents leaf scorch.
Pinch out flower spikes
Copperleaf produces small catkin-like flower spikes that are ornamentally insignificant. Pinching them out as they appear redirects energy into producing the colourful foliage.
Hard prune in spring
Cut back hard by up to half in spring to keep the plant compact and stimulate fresh, vividly coloured new growth. Without pruning, plants become leggy over time.
Bring indoors before frost
Copperleaf is frost-tender. In temperate climates, move container plants indoors when night temperatures drop below 10°C. Overwinter in a bright, warm position.
