How to Grow Dwarf Red and Orange Calla Lilies

Purchase red and white callalily rhizomes labeled as dwarf, miniature or short. These plants typically reach heights of 18 to 22 inches, whereas full-size callalilies may reach 36 inches.

Fill a 6-inch plant pot three-fourths full of potting medium. A mixture of 1 part peat moss, 1 part sterilized potting soil and 1 part perlite works well.

Place one calla lily rhizome in the pot’s center and cover it with potting medium. Firm the soil down with your hands, securing the rhizome and eliminating air pockets.

Water it thoroughly until water runs freely through the pot’s bottom drainage hole. Placing the pot in a shaded area allows roots to form. Water it again when the soil dries to 1 inch below the surface of the soil.

Begin fertilizing it with water-soluble fertilizer designed for flowering plants when new growth appears, approximately one to two weeks after planting.

Move the callalilies to an area with more sun, gradually increasing their exposure until they tolerate full sun without developing leaf scald. Grow inside plants on a sunny windowsill.

Move the pots inside in the fall when the danger of frost threatens. Overwinter the pots in a cool, dark area that remains above freezing.

Begin watering again in late winter or early spring to prepare your calla lilies for outside growing.
