  • water dropWater

    The New York Aster 'Rosenwichtel' prefers to be watered regularly to keep its soil evenly moist but not saturated. The frequency of watering should be adjusted based on weather conditions, but generally, once a week is adequate. During the active growing season in spring and summer, it’s important to ensure that the plant receives about one inch of water (which is roughly 0.623 gallons) weekly, either from rainfall or manual watering. During the winter months or cooler weather, reduce watering since Asters need less water as they go dormant. If the leaves are wilting or the top inch of soil is dry, that's an indication that the plant needs water.

  • sunLight

    The New York Aster 'Rosenwichtel' thrives in full sun to partial shade conditions. Ideally, it should be positioned in a spot where it receives at least 6 hours of direct sunlight each day. If the plant is placed in too much shade, it may not bloom as prolifically. However, in hotter climates, protection from the intense afternoon sun can help prevent scorching of the leaves.

  • thermometerTemperature

    The New York Aster 'Rosenwichtel' can tolerate a wide range of temperatures but grows best between 60°F and 75°F. It can survive minimum temperatures down to around 20°F, making it suitable for cooler climates. On the hotter end, it can tolerate temperatures up to about 85°F, but it's important to provide extra water during hotter spells to prevent stress.

  • scissorsPruning

    New York Aster 'Rosenwichtel' benefits from pruning to encourage bushier growth and more blooms. The best time to prune is in early spring, just as new growth is beginning to show. Cut back the previous year’s stems to about 4-6 inches above the ground. Additionally, deadhead spent flowers regularly during the blooming season to extend blooming and prevent self-seeding if desired.

  • circleLife cycle

    New York Aster 'Rosenwichtel' begins its life cycle as a seed, which germinates when soil temperatures and moisture levels are suitable, typically in the spring. The seedling stage follows germination, during which roots, shoots, and leaves develop, allowing the plant to photosynthesize and grow. As the plant matures during the vegetative stage, it forms a bushy structure with several stems and larger leaves, preparing for flowering. The flowering stage usually occurs in late summer to fall, characterized by the blooming of numerous daisy-like flowers with pink to purple petals and yellow centers, which attract pollinators. After pollination, the flowers will develop into fruit, technically achenes, containing seeds that can be dispersed to initiate new life cycles. Finally, the plant enters a period of senescence after seed dispersal, where it may die back, especially in colder climates, or it may return the following spring if the conditions are favorable.

      Spring to Early Summer

    • The New York Aster 'Rosenwichtel', a variety of Symphyotrichum novi-belgii, is commonly propagated through division. This is best done in the early spring as the new shoots are emerging from the soil. To propagate by division, carefully lift the plant from the soil with a shovel, ensuring a generous amount of roots and soil are attached. Gently separate the clumps into smaller sections, each with several shoots and a healthy root system. These divisions can then be immediately replanted into prepared soil, spacing them about 18 inches (approximately 45 centimeters) apart to allow room for growth. Adequate watering after replanting is crucial to ensure the divisions establish well. Division not only helps propagate new plants but also rejuvenates older clumps that may have become woody or less vigorous.
