Navelwort problems — and how to fix them
Navelwort (Umbilicus rupestris) 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.
Tuber rot in summer
If the dormant tuber is kept too wet in summer it rots rapidly. Once leaves have died back, keep the pot almost completely dry and in a cool, shaded spot until new growth resumes in autumn.
Premature dormancy from heat
Temperatures above 22°C trigger early dormancy. In heated indoor environments the active season may be shorter than expected. Keep the plant in the coolest available spot during spring to extend its growing season.
Aphids on flower spikes
The succulent flower spikes in spring attract aphid colonies. Treat with a forceful water spray to dislodge them, or apply an insecticidal soap solution; avoid systemic insecticides on this small plant.
Prevent navelwort problems before they start
Most navelwort issues are care-mismatch, not bad luck. Dial in the basics:
