Growing calla lilies in large pots will help to keep the soil moist, and will ensure there’s plenty of room for the tubers to grow. [2] X Research source
The bulb shouldn’t be planted too deep, which is why you fill the pot most of the way before planting it. [4] X Research source
Dark leaf tips is a sign of overwatering. [6] X Research source
With proper feeding, watering, and light, the plant should start to flower eight weeks after planting. [8] X Research source
When the weather starts to cool down at the end of summer, bring the calla lily back inside.
Calla lilies go into a state of dormancy once a year. They need this rest period in order to create their beautiful and abundant flowers. A good temperature range for dormant calla lilies is between 60 and 75 F (15. 5 and 24 C). [11] X Research source
If you’re transplanting more than one calla lily, space them 12 inches (30 cm) apart.
When the calla lily starts to flower, you can increase the feedings to every two weeks.
If you live in a warmer climate with milder winters, you can actually leave the bulbs in the ground for the season. To help keep the bulb warm, cover the area with a thick layer of mulch for the winter.
Store the bulb between 60 and 75 F (15. 5 and 24 C) for the duration of the winter. [22] X Research source
Thanks to plant breeding, there are also hybrids of these two groups which can be hard to tell. Check with a website or plant expert for specifics.
