Care
Zantedeschia aethiopica ‘White Giant’ Care
Grow in partial sun or bright shade. In hotter regions, protection from strong afternoon sun helps maintain healthy foliage.
This plant prefers rich, well-draining soil that remains consistently moist. Water regularly, especially during active growth, and avoid allowing the soil to dry completely.
If fertilization is needed, apply a slow release fertilizer during the growing season according to label directions.
In colder zones, rhizomes may be lifted and stored indoors before hard frost, or grown in containers that can be overwintered inside.
Container Growing Notes
White Giant Calla Lily performs very well in large patio containers. Use a well-draining but moisture-retentive potting mix and a container with drainage holes.
Container-grown plants require more frequent watering than those planted in the ground, particularly during warm weather.
Plants hardy in the ground may require winter protection when grown in containers in colder zones.
