Troubleshooting
Black Rose Aeonium problems — and how to fix them
Black Rose Aeonium (Aeonium 'Zwartkop') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Colour fading to green
The near-black colouration of 'Zwartkop' depends on strong direct light. Insufficient light causes leaves to turn dull green. Move to the brightest available position, ideally outdoors in summer if frost risk has passed.
Summer dormancy confusion
Rosettes cup and shed leaves in summer, alarming new owners. This is normal dormancy behaviour. Withhold water and avoid repotting; the plant will resume growth and unfurl rosettes in autumn.
Aphids on new growth
Soft new growth in spring can attract aphids. Blast off with a jet of water or apply insecticidal soap spray. Avoid systemic insecticides during the active growing season.
