Green-Flowered Galtonia problems — and how to fix them
Green-Flowered Galtonia (Galtonia viridiflora) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Winter cold damage to bulbs
Rated RHS H3, this species is less cold-hardy than G. candicans. In areas with hard frosts below -5°C, lift bulbs after foliage dies back in autumn, dry them off, and store in a cool frost-free place until spring.
Failure to flower after dry spells
Unlike many summer bulbs, G. viridiflora is intolerant of drought during growth. A dry spell in early summer interrupts stem and flower development. Keep soil consistently moist with regular irrigation or a moisture-retaining mulch.
