Troubleshooting
Zantedeschia 'Flame' problems — and how to fix them
Zantedeschia 'Flame' (Zantedeschia 'Flame') 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.
Rhizome rot
Cold, soggy soil and overwatering rot the tuber. Plant in free-draining mix, water moderately, and store dormant rhizomes dry and frost-free.
Weak colour
In low light the yellow-to-orange transition is muted. Give full sun to bright light to develop the strongest flame tones.
Few blooms
Excess nitrogen or shade reduces flowering. Use a potassium-rich feed and a brighter position to encourage repeat blooms.
Frost loss
The rhizome cannot survive freezing in colder zones. Lift after foliage dies down, dry, and overwinter frost-free for spring replanting.
