Troubleshooting
Pink Calla Lily problems — and how to fix them
Pink Calla Lily (Zantedeschia rehmannii) 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.
Failure to flower
Usually caused by skipping dormancy (keeping the plant too wet year-round) or insufficient light. Allow proper dry dormancy for 6-8 weeks and ensure bright conditions during active growth.
Rhizome rot
Excessive moisture during dormancy is the main cause. Keep rhizomes barely dry during their rest period and in well-draining compost.
Yellowing leaves (premature)
Natural at the end of the season, but premature yellowing may indicate overwatering or root issues. Check drainage and soil moisture.
Spotted or streaked leaves
Could indicate virus infection (Dasheen mosaic virus) if combined with stunted growth. Remove and destroy affected plants to prevent spread.
Aphids
Common on soft new growth and flower stems. Treat promptly with insecticidal soap or a strong water spray to prevent rapid colony build-up.
