How to Grow and Care
Divide mature plants in spring, just as the new shoots begin to grow. This should be done every few years to avoid crowding of plants.
As with many other flowering plants, dead head (cut back spent flowers) to make room for newer blossoms. This will extend the health and flowering of your plants. Be sure to dead head early on in the blooming season. Blooming will be reduced if done too late. This will also restrain unwanted reseeding which will cause plant overcrowding.
Remember, Asters are prone to mildew so be careful to plant them in areas with good circulation and good sun exposure.
As with other flowering plants, do not allow water to saturate leaves. Be sure to water at the plant's roots to prevent mildew and mold. Drip irrigation and utilization of a soaker hose work very well in watering these plants… – See more at: How to Grow and Care for Aster.
