ANSWER: Calla lilies can be grown outdoors, or they can be grown in containers indoors as part of a houseplant collection. Calla lilies are winter hardy in USDA Plant Hardiness Zones 8 through 10. In other zones, they can be grown outdoors as annuals.
To some degree, calla lilies are outdoor plants. They will flower in full sunlight, but their foliage is best kept indoors or in partial shade. Many gardeners treat these plants as annuals, planting them outdoors in spring and taking them inside before the first frost.
Care of calla lilies requires that they be planted in loose, well-drained soil. They prefer to be located in full sun or partial shade in warmer climates. Calla lilies are typically planted in the spring. However, wait until the threat of frost has passed and the soil has warmed sufficiently before planting calla lilies.
Can calla lilies survive winter?
Overwintering Calla Lilies Outside 1 Consider keeping your Callas outside if you live in a mild climate. Calla Lilies will survive outdoors over winter in mild climates that don’t experience much sustained snow, deep freezes and heavy prolonged rainfall in the colder months. They can generally cope outdoors through winter in zones 8 through 10.
Keeping callas year round is possible, but how you treat your plant to get blooms again next year will depend on your hardiness zone. You can rely on calla lily hardiness through zone 8 or maybe 7 at a stretch. If you live somewhere colder, you will need to bring your plant indoors for the winter. One solution is to keep your calla lily potted.
This is especially important when they are grown in containers. In warm climates where calla lilies are winter hardy (zones 8-10), the rhizomes can be left in the ground to bloom again the following summer. The plants may need to be divided every few years to keep them blooming well.
When we were reading we ran into the inquiry “When can I start calla lilies indoors?”.
Answer: Plant calla lily rhizomes 1 to 2 inches deep in a well-drained potting mix about 6 to 8 weeks before the average last spring frost in your area. After potting, water well and place the containers in a warm, 70 to 75°F location.
How to grow calla lily from seeds?
To grow calla lilies, first get a deep pot with lots of drainage holes that’s about 12 inches wide. Then, mix potting soil with enough warm water to make it moist, and fill your pot 2/3 full. Next, put your bulb in the center of the soil with the growth facing upward, then fill the pot to the top with soil.
Moreover, why is my calla lily not blooming?
The soil where your plant grows may be too dense or may contain too much heavy clay. Your calla lily may be planted too deep in the soil. You may be overwatering or under-watering your calla lily. Your calla may need a little fertilizer to give it the necessary nutrients.
How much light do calla lilies need inside a house?
Calla lilies grow best in full sun to part shade. In containers, it is recommended that calla lilies be placed in a location where they can receive about six hours of sunlight each day.
