When Should Michael Maeweis Be Divided?

Asters, also known as Michaelmas daisies, are a group of late flowering perennials that provide fall color after the blooms of summer have gone. They can be grown in dappled or partial shade, in any type of soil, with slightly moist soil being preferable for species prone to powdery mildew. Asters can also be grown successfully in containers, preferably where the soil remains slightly moist.

Propagation of Michaelmas daisies is easy by dividing the plant at the roots. To do this, separate the rootstock by inserting a spade in the middle of the aster, and move the new plant to another suitable spot. Divide plants regularly in spring to maintain health, flower power, and control their size. This is required every 1-3 years for S. novi-belgii and every 3-5 years for S. novi-belgii.

Asters bloom from August through to the end of October, except for Aster alpinus and A. tongolensis ‘Napsbury’, which flowers from late spring to early summer. They can flower from anytime from spring to late autumn (depending on the species). Asters range in size from 15 to 125 cm in height and have daisy-like flowers of white, pink, purple, or blue.

Asters can be cut back in spring, in March or April, and the plant will sprout anew near the ground. Division is the easiest way to propagate small-flowered asters. Lift clumps every three to five years in spring, remove any old and woody material, and divide them in early spring when the new shoots start to sprout.

Most asters will need dividing every fourth year to maintain vigour, but all asters are best divided in spring as new growth starts.
