Troubleshooting
Clustered Freesia problems — and how to fix them
Clustered Freesia (Freesia corymbosa) 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.
Corm rot
Caused by Fusarium or bacterial rot in wet, poorly drained soil. Ensure fast drainage and avoid overwatering during dormancy. Discard soft or discoloured corms before planting.
Aphids and thrips
Both pests feed on stems and buds, distorting growth and transmitting viruses. Inspect regularly; treat with insecticidal soap or neem oil at first sign of infestation.
Failure to bloom in heat
Freesias cease flowering when temperatures exceed 21–24°C. In warm climates plant corms in early autumn for late-winter/spring bloom before summer heat arrives.
Prevent clustered freesia problems before they start
Most clustered freesia issues are care-mismatch, not bad luck. Dial in the basics:
