Every few years it's that time again: The autumn asters have to be shared. The regular rejuvenation of the perennials is important to maintain their flowering ability and vitality. By division, they become eligible for the formation of a strong new shoot with many flowers. A positive side effect of this measure is that you can multiply the plants in the same way. How exactly you proceed when sharing the autumn asters, we show them here step by step.
Cut off the old flowering plants in late autumn (left) and dig out the roots generously (right)
Cut the stems about a hand's breadth above the ground. Healthy plant parts are allowed on the compost. If the asters are infected with mildew, the pruning is better disposed of in the residual waste. If the plant shows loose leaves and black shoots, it suffers from aster-wilt and should be removed together with the roots. First use a spade to prune the root ball and then gently lift out the roots. Then separate pieces with two to three eyes for a new shoot. For better visibility, the root parts are best laid on a piece of jute or in a bucket.
The storage roots are broken into several pieces and then put back into the bed (left). Then water well (right)
The cuts are replanted at other sunny and nutrient-rich locations. Any wild growth should be removed beforehand - preferably a little more thoroughly than here. Put the parts back into the soil as deep as the mother plant used to. Good casting supports rooting in the first few weeks after the division. The next time the autumn asters are picked up, three to four years may pass again.
