Aster’s have bright flowers occurring in the fall when the garden is usually looking bland and not blooming. A common name for the aster is Michaelmas daisy. A great money maker for the aster is that it attracts butterflies.

When blooming, aster’s produce pink, white or blue flowers in late summer or fall. They thrive where summers are cool and moist.

The can grow between 8 inches and 8 feet depending on what variety is growing.

Unfortunately, the aster is known to fall a victim to mildew or rust diseases. This can be avoided if you choose disease resistant varieties.


The best time to plant an aster is spring. Space the plants 1-3 feet apart depending on growth for variety. Loosen the soil with a tiller or fork. Dig the hole twice the diameter of the root ball and place the plant in the hole so that the top of the root ball is level with the soil surface.  Fill in around the root ball and mix in compost while lightly firming the soil. Water the plant and soil around it thoroughly.


Compost the base of the plant each spring and top that off with some mulch. This will hold moisture and reduce the growth of weeds. If there is less than 1 inch (2.5cm) of rain per week then water appropriately.
