Troubleshooting
Bearded Trichodiadema problems — and how to fix them
Bearded Trichodiadema (Trichodiadema barbatum) 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 rot during dormancy
Overwatering in the summer dormancy period is the most common cause of plant death. Reduce to near-drought conditions in summer.
Failure to flower
Trichodiadema needs a cool, dry summer rest followed by resumption of watering in autumn to trigger winter-spring flowering. Consistent warmth and moisture suppresses blooms.
Loss of bristle tips
Browning or loss of the distinctive white bristles can occur in very humid conditions or after physical damage. There is no remedy; new leaves will develop normal bristles.
Mealybugs
May appear in the leaf axils around the caudex. Treat promptly with isopropyl alcohol on a cotton swab.
Insufficient caudex development
Raised cultivation (partially exposing the root caudex) in a pot encourages the ornamental swollen base to develop. Ensure very gritty, lean compost.
