The indoor calla (Zantedeschia) comes from the swampy regions of South Africa. It must always be kept moist during growth and especially during flowering. She doesn't get any water when she's resting. The earth must dry out completely during this time.
How often and how much water does my calla lily need?
The calla should always be kept well moist during the growth and flowering period. Starting in January, slowly increase the amount of water, keep it constantly moist during the flowering period and occasionally allow water in the saucer. After flowering, let the soil dry out and stop watering.
Watering after growth phases
The growing season of calla lilies begins in January. At this time you remove the houseplant from its winter quarters. At first, water sparingly and gradually increase the amount of water.
During the flowering period, the soil must always be moist. The houseplant can now even tolerate water standing in the flower saucer occasionally. Use a spray bottle to ensure high humidity.
After the flowering period, allow the potting soil to dry out. It is no longer watered at all. The humidity should no longer be high either.
Tips & Tricks
The calla lilies like soft water. Use rainwater or let tap water sit for a while.
