Troubleshooting
Green Ixia problems — and how to fix them
Green Ixia (Ixia viridiflora) 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
The main risk in cold wet winters. Lift corms after foliage dies back in regions with wet winters and store dry at 10-15°C.
Poor flowering
Caused by insufficient sun, overly rich soil, or corms planted too shallow (plant 8-10 cm deep).
Stem laxness
Thin wiry stems may flop in exposed sites; stake with twiggy sticks or grow against a warm wall.
Aphids
Can colonise stems in spring. Blast off with water or use insecticidal soap.
Frost damage
Tops are frost-tender; in zones below 9, lift corms in autumn and store frost-free until spring.
