Callas can be grown indoors in containers or outdoors in the garden. In areas with a warm climate, calla lilies grow constantly throughout the year. In colder climates, you can grow the calla lilies as annuals or dig them up in the fall and replant the next year.

Steps

Method 1 of 3: Planting Calla Lilies in Pots

1. 1 Plant calla lilies from tubers or rhizomes. Although they can be planted from seed, it takes a long time and calla lilies do not germinate well.
2. 2 Plant dormant tubers in 15-20 cm pots., a few weeks before the last frost expected in your area. If you live in a warm climate or the threat of frost has passed, you can plant the tubers right in the garden.
   • Submerge the tubers 8-10 cm below the soil surface.
3. 3 Place the pots on a sunny window. Keep the soil moist until the plants begin to grow and it is time to transfer them to the garden or transplant them into larger containers.

Method 2 of 3: Planting calla lilies outdoors

1. 1 Choose an open area with partial sun that retains moisture if you live in hot climates. Choose an area with full sun and moisture if you live in a cooler area.
2. 2 Prepare the soil for your calla lilies. Till the soil before planting and fertilize the soil with organic mulch to help it retain moisture. This is especially important if your soil is rocky or sandy.
3. 3 Transplant plants or tubers into the ground as soon as there is no threat of frost.
   • Plant the plants at least 30 cm apart. Some calla lilies grow up to 1.2 m with leaves 30 cm or more.
4. 4 Water the plants well and keep the soil moist throughout the growing season.
5. 5 Fertilize your flowers regularly using a water-soluble, all-purpose plant fertilizer. You may need to fertilize more than usual when the plants are producing flowers.
6. 6 Stop watering and feeding plants at the end of the growing season. This will allow the soil to dry out and the plants will die off. Even if you live in a warm climate, calla lilies need to go to winter rest in order to bloom again next year.
7. 7 Dig the calla lilies out of the ground before the first frost if you live in cold climates. Grab the plant close to the ground and wiggle it back and forth until the soil around the base looses, then gently pull on the tuber and lift it out of the ground.
8. 8 Sift through the soil with your hands or gently rotate it with your hand shovel to find small tubers that are in the ground.
9. 9 Trim off any remaining vegetation from the tubers, then place them in the sun to dry for a few days.
10. 10 Store tubers in dry peat in a paper bag. Keep them at a temperature of 10-15 ° C.
11. 11 Break the clusters into individual tubers before planting them in the spring.

Method 3 of 3: Growing Calla Lilies in Containers

1. 1 Plant dormant tubers in 40 cm pots. or more if you want to grow flowers in containers. Although the root system of calla lilies is not very widespread, using a large pot helps the soil stay moist and has enough room for tubers to spread and new plants to grow.
2. 2 Use potting soil with organic mulch at the base, or fertilize the soil with organic matter before planting.
3. 3 Keep containers indoors. Calla lilies grow well as floor plants, near large windows or glass doors, where they receive a lot of sunlight.
4. 4 Move the plants outdoors when all signs of frost are gone if you want to grow them outdoors in pots. Potted calla lilies complement gardens, patios, and porches well.
5. 5 Water the plants regularly and make sure the soil remains moist. Plants grown in containers dry out faster than those grown in the ground.
6. 6 Fertilize potted calla lilies with an all-purpose plant fertilizer when buds begin to develop on them.
7. 7 Stop watering and feeding the plants at the end of the growing season to allow them to go dormant.
8. 8 Cut the plants to ground level and bring the pots back indoors for the winter if you live in cold climates. Store pots in a cool, dark place no colder than 5 ° C. Or, you can dig the tubers out of the pots and store them in the turf during the winter.
9. 9 Ready.

Warnings

• Spider mites often develop on calla lilies. If you see cobwebs on the leaves, hose them with a strong jet of water, and then spray the plant with a solution of water and soap.
