WaterFor the China aster or Callistephus chinensis 'Duchess Series', consistent moisture is key, so water regularly, aiming for at least an inch of water weekly. During hot and dry spells, this may mean watering every other day to maintain soil moisture. Avoid overhead watering to prevent foliar diseases; instead, water at the base of the plant. Reduce watering as the plant nears the end of its blooming cycle to allow the soil to dry out slightly.
LightChina aster thrives in full sun, meaning it requires at least 6 to 8 hours of direct sunlight daily. Positioning it in a spot where it can receive unfiltered sunlight throughout the day will encourage the most abundant flowering.
TemperatureChina aster prefers temperatures between 60°F and 75°F for optimal growth. The plant can handle minimum temperatures down to 20°F for short periods, but frost can damage it, so it is best to protect it or bring it indoors if frost is expected. Ideal growing conditions avoid extreme heat, as temperatures above 80°F may stress the plant and reduce flowering.
PruningChina aster should be pruned to encourage bushier growth and more blooms. Pinch back the tips of the young plants early in the season, and deadhead spent flowers regularly to promote continuous blooming. The best time to prune is in the late spring or early summer before the plant has set buds.
CleaningAs needed
SoilThe best soil mix for the China Aster, also known as Callistephus chinensis Duchess Series, should be well-draining and fertile with a good amount of organic matter. A mixture of loam, peat, and sand in equal parts can be ideal. The soil pH should be between 5.5 and 7.5 for optimal growth.

Life cycleThe Aster 'Duchess Series' (Callistephus chinensis 'Duchess') begins its life cycle as a seed, which, when sown in late winter to mid spring, germinates in light and warmth. Seedlings emerge within 2 to 3 weeks and continue to grow, developing a rosette of leaves. With proper care, seedlings are transplanted outdoors after the risk of frost has passed, where they establish themselves in full to partial sun. Throughout the summer, the Asters grow vigorously, producing lush foliage and then flowering, typically from late summer to fall, showcasing a bounty of double blooms with a variety of vibrant colors. After blooming, the plant sets seeds, completing its annual cycle. If allowed, the seeds can be dispersed by wind or mechanical means, initiating a new generation of Asters for the following season.
PropogationPropogation time
Spring to summer
The most popular method of propagation for the China Aster 'Duchess Series' is through seed sowing. Seeds can be started indoors about 6 to 8 weeks before the last expected frost for an early start. It is best to use a fine seed-starting mix, placing the seeds on the surface and lightly pressing them into the soil. They require light to germinate, so they should not be covered with soil but can be lightly misted to keep moist. Asters prefer a germination temperature of about 70°F (21°C), and typically, germination occurs within 7 to 14 days. Once seedlings emerge and danger of frost has passed, they can be transplanted outdoors into well-drained soil with full to partial sunlight.
