  • water dropWater

    New England Aster 'Rosa Sieger' prefers consistent moisture, so water this perennial plant deeply once a week, providing about 1 to 1.5 inches of water each time. During hot and dry periods, you may need to water twice a week to maintain moist soil, ensuring the plant does not sit in waterlogged conditions. It's best to water in the morning so the foliage has time to dry out over the course of the day, reducing the risk of fungal diseases. If you're using a watering can or hose, aim directly at the soil and not the foliage. Over the course of a month, this comes to roughly 4 to 6 gallons of water, depending on weather conditions and soil type.

  • sunLight

    New England Aster 'Rosa Sieger' thrives in full sun, which means it requires at least 6 hours of direct sunlight each day. The best spot for this plant would be in an unobstructed location where it can receive generous sunlight throughout the day. Partial shade is acceptable, especially in hotter climates, but full sun is ideal to promote abundant blooms.

  • thermometerTemperature

    New England Aster 'Rosa Sieger' is hardy in temperatures as low as 20 degrees Fahrenheit and can tolerate up to around 100 degrees Fahrenheit. It prefers growing in a temperate range of 60 to 75 degrees Fahrenheit for optimal growth. Ensure the plant is well-mulched to help protect its roots from extreme temperature fluctuations.

  • scissorsPruning

    New England Aster 'Rosa Sieger' should be pruned to encourage bushier growth and more blooms. In early spring, cut back last year's growth to about 4 inches above the ground. Pinch back the tips of new growth in late spring to early summer to promote bushier plants. Prune after flowering if desired to maintain a tidy appearance.

  • circleLife cycle

    The New England Aster 'Rosa Sieger' starts its life as a seed, which, when sown in late winter or early spring after stratification, will germinate in the presence of adequate warmth and moisture. Upon germination, seedlings emerge and establish a root system, followed by leaf production as they enter the vegetative growth stage during which the plant develops its foliage and stems through the spring and summer. This perennial then enters the flowering stage in late summer to fall, producing vibrant pink to rose-purple blooms that are attractive to pollinators like bees and butterflies. After flowering, the plant sets seed in the form of achenes which can be dispersed by wind to foster new plant colonies. Post-bloom, the aster enters a period of senescence in late fall to winter; the above-ground foliage dies back with the first frost and the plant enters a dormant phase, surviving the cold season as root stock or underground rhizomes. With the return of spring warmth, the New England Aster 'Rosa Sieger' re-emerges from dormancy, initiating a new growth cycle.

    • The most popular method of propagating the New England Aster 'Rosa Sieger' is through division. This perennial plant can be divided in the spring or early fall, when the plant is not in active bloom. To divide, you would carefully dig up an established clump and gently separate the roots into smaller sections, ensuring each new section has multiple shoots and a portion of the root system. These divisions can then be replanted into prepared soil, spaced about 18 inches (approximately 45 centimeters) apart to allow for growth and air circulation. Proper watering is essential after replanting to help the new divisions establish. Division not only helps propagate new plants, but also invigorates the parent plant and encourages more vigorous growth.
