Zantedeschia 'Edge of Night' problems — and how to fix them
Zantedeschia 'Edge of Night' (Zantedeschia 'Edge of Night') 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, wet, poorly drained soil rots the rhizome quickly. Plant in free-draining mix, avoid overwatering, and never leave tubers in waterlogged pots over winter.
All leaves, few flowers
Too much nitrogen or too little light reduces blooming. Switch to a higher-potassium feed and give full sun to bright light.
Leaf scorch
Margins brown in fierce afternoon heat or after letting the soil dry out. Provide afternoon shade in hot climates and keep moisture steady during growth.
Failure to overwinter
In zones below 8 the rhizome dies if frosted. Lift after foliage dies back, dry and store frost-free, then replant in spring.
