New England aster

New England aster should be watered when the top inch or 2 of soil feels slightly dry. This should amount to approximately 1-2 inches of water each week. If there is a lot of rainfall that week, you may need to adjust your watering schedule to account for the extra moisture received. It is best to water your New England aster in the morning. Water slowly and deeply for a few minutes so that the water has a chance to reach the roots of the plant.

New England aster prefers direct sunlight for at least 4 to 6 hours each day. During the summer months, the plant may receive more sunlight if it's in a sunny location, as long as the soil is kept adequately moist throughout the season. For optimal growth and flowering, the aster should receive full sun in the morning, with afternoon shade when temperatures reach 80°F (27°C) and higher. In cooler climates with lower temperatures, the plant can tolerate more direct sun without afternoon shade.

New England Aster, or Symphyotrichum novae-angliae 'Andenken an Alma Pötschke', primarily blooms from mid-summer to early fall and requires very little pruning. Prune the plant annually in late fall or early winter, and only remove stems that are dead, damaged, or infested with disease. For the height and width, prune the plant back after flowering and thin out stems that have become too bushy. Pruning should be done carefully and sparingly; be sure to cut the stems back to areas with living tissue to prevent damaging the plant. Additionally, trim a few of the longest stems after flowering in order to keep the plant from becoming leggy.
