Aster is an undemanding genus, suited for gardeners appreciating low-maintenance perennials. Basic care involves full sun to partial shade, well-draining soil with moderate levels of organic content, and regular watering to establish the plants. Once mature, aster tolerates drought, making it a resilient genus. Common challenges include overwatering, which can lead to root rot, and susceptibility to mildew in poor air circulation. Seasonal considerations involve mulching to protect roots in winter and pruning spent flowers to encourage rebloom or prevent self-seeding.
