watering
Calico asters (Symphyotrichum lateriflorum 'Lady in Black') should be watered deeply when the top 2 inches of soil become dry. Depending on the temperature and light exposure, this may mean watering weekly or every few days. Once established, calico asters have low to moderate water requirements, and benefit from regular deep watering. Be sure to water near the root zone rather than over the leaves. Excess water should always be able to drain away, as asters are susceptible to root rot.
sunlight
Calico aster (Symphyotrichum lateriflorum 'Lady in Black') do best in locations with full sun to partial sun, or 4-6 hours of direct sunlight each day. This species tolerates more sun in cooler climates, but can also thrive in part shade. It's important to find the right balance for this plant, too much shade can cause it to become leggy and too much sun can cause its foliage to become scorched. Water regularly and deeply to keep the soil moist until the plant is established. After that, this species should do fine with occasional deep soaking.
pruning
Calico Aster should be pruned back aggressively in early spring, before new growth appears. It is important to prune it back far enough to remove the old, dead stems and open up the center of the plant, allowing for new growth. Pruning back to 12-15 inches will produce the most abundant new growth and flower production afterwards. Deadheading spent flowers will also help to promote more blooming and can be done throughout the growing season.
