Cut perennials and roses to stimulate further flowering

With the exception of just-flowering and late fall perennials, perennial clumps that are too dense or over-aged can be divided now and planted in a new location. A typical sign of overaging is that new shoots are formed mainly at the edges and the perennial becomes bare on the inside; in addition, flowering performance and vigor decline.

In autumn there is still some work to be done in the rose bed: To protect the grafting site from severe frosts, mounding is done and, where necessary, long shoots are shortened somewhat.

In order for roses to remain healthy and vigorous and for the remontant varieties to show good post-blooming in the fall, they now need a strong top-up fertilization after the first flush of flowers in June.
