Troubleshooting
Black Rose Aeonium problems — and how to fix them
Black Rose Aeonium (Aeonium arboreum '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.
Summer-dormancy confusion
Rosettes naturally close up and drop lower leaves when resting in summer heat, which looks like distress. Reduce watering rather than soaking it, and growth resumes in autumn.
Reversion to green and etiolation
Insufficient sun loses the black colouring and stretches the stems. Provide strong direct light to keep rosettes dark and compact.
Rot from overwatering
Watering during dormancy or using soggy soil rots the stems and shallow roots. Match watering to its winter-growth cycle and ensure free drainage.
Bare leggy stems
It naturally drops lower leaves, leaving tall bare stalks. Behead and re-root leggy rosettes to rejuvenate a fuller plant.
