Answer: Plant calla lilies in rich, humusy soil in a partly shady spot with morning-only sun or bright dappled light all day. Keep the soil evenly moist, meaning damp like a wrung out sponge, not sopping wet and not dried out. Look for blooms in late summer.
Calla lilies are not winter hardy in Pittsburgh (the winters are far too cold) so you would need to bring them indoors in the fall if you want to save them for next year.
In the fall, after frost kills the tops, trim off the dead stems and gently dig up the rhizomes. Brush off the soil or rinse clean and air dry at room temperature for several days. Then pack in dry shavings or dry peat moss in a single layer in a cardboard box and store in a cool place (about 55 degrees) until spring.
In spring, plant outdoors when all danger of frost has passed and the soil has had a week or two to warm up.
