watering

Water New England aster (Symphyotrichum novae-angliae 'Roter Stern') deeply but infrequently, providing just enough water to moisten the soil to a depth of 8 to 12 inches. Water the plant thoroughly until water runs freely from the drainage holes. Usually, it's necessary to water every 7 to 10 days during dry spells, once established. The quantity of water depends on environmental factors, including temperature, humidity, and light intensity. Generally, plants should receive 1 to 2 inches of water per week.

sunlight

New England aster (Symphyotrichum novae-angliae 'Roter Stern') prefers full sun and grows best in areas that receive at least 6 hours of direct sunlight per day. It can also tolerate partial shade for part of the day, but it won't flower as profusely or be as vigorous as it would be in full sun. While the plant needs plenty of sunlight, especially during the summer, it should also be shielded from intense midday sunshine, especially during the hottest times of the year.

pruning

When pruning a New England aster (Symphyotrichum novae-angliae 'Roter Stern'), the timing should be done in late winter or early spring. Doing this will help to encourage healthy and vigorous growth. For pruning amount, no more than 1 third of the entire plant should be removed. This will allow the plant to regrow again vigorously and maintain its signature bushy shape. Deadheading should also be done as needed to maintain the quality of the blooms.
