Step 2: Choose the Right Location

Select a well-draining location in your garden that receives at least six hours of sunlight per day. Callas prefer slightly acidic to neutral soil with a pH between 6.0 and 6.5. If needed, amend your soil with peat moss, compost, or other organic materials to improve its fertility and drainage. Use hydro granules for baskets, pots, and bowls.

Step 3: Prepare the Soil

Loosen the soil to a depth of about 30 cm (12 inches) using a garden fork or tiller. This will help the tubers establish a strong root system and promote healthy growth. Mix in a slow-release, balanced fertilizer, following the package instructions for the correct application rate.

Step 4: Plant the Tubers

Plant the calla tubers in spring, once the threat of frost has passed and soil temperatures have reached at least 60°F (15°C). Dig a hole about 3-4 inches deep and place the tuber with the growing point facing upward. Space the tubers approximately 12-18 inches apart, depending on the mature size of the variety you have chosen.

Step 5: Water and Mulch

Cover the tubers with soil, and water the planting area thoroughly. Apply a 5-8 cm layer of organic mulch, such as bark chips or compost, around the base of the plants. This will help retain moisture, suppress weeds, and regulate soil temperature.

Step 6: Care for Your Callas

Water your callas regularly, keeping the soil consistently moist but not waterlogged. During the growing season, apply a balanced liquid fertilizer every 4-6 weeks to support healthy growth and vibrant blooms.

Step 7: Monitor for Pests and Diseases

Keep an eye out for common pests, such as aphids and spider mites, and treat them promptly with insecticidal soap or other appropriate measures. Watch for signs of diseases, such as root rot or bacterial soft rot, and address any issues by improving soil drainage or applying the necessary fungicides.

Step 8: Enjoy the Blooms

Calla plants typically bloom within 8-12 weeks after planting the tubers. The elegant, trumpet-shaped flowers will last for several weeks and can be cut for indoor arrangements or left in the garden to provide a stunning display.

Step 9: Prepare for Winter (optional)

In colder climates (hardiness zones 7 and below), you may need to dig up the tubers and store them indoors for the winter. After the foliage has died back, carefully lift the tubers from the ground, clean off any excess soil, and let them dry for a few days. Store the tubers in a cool, dark place, such as a garage or basement, in a container filled with slightly damp peat moss or vermiculite.
