Do you cut back perennials in the fall?
Do you still need to fertilize the plants?
You should also treat easy-care perennials to a little care.
Chrysanthemums, asters or sedum - many hardy perennials bloom happily in September, isn't there anything to do?
Yes, even in autumn there is work to be done in the garden bed to bring out the best in them.
However, you don't have to do a tabula rasa like usual and put away every leaf.

As
Mein Schönen Garten
explains, severe pruning is no longer necessary for perennials - roses can even freeze to death as a result.
An exception are sick plants, whose spores can otherwise spread and infect others.
Plants that are infested with mildew, for example, should be sorted out in good time.
The remaining plants and dried leaves provide shelter for animals in winter, so cutting back the perennials in spring is sufficient.
But there is a little you can do to keep the plants in the perennial bed healthy.
The magazine
Das Haus
recommends the following care measures in September:
Watering yes, fertilizing no: Even if there is greater humidity, especially at night, you should not rely on it alone.
Especially in September there can still be warm, sunny late summer days when dry plants should be watered.
However, you should stop fertilizing so as not to stimulate the plants to grow again.
Dividing Perennials: For spring bloomers, now is a good time to divide them to rejuvenate or propagate.
Hostas, astilbes or monkshood tolerate this well, but most of the autumn-blooming perennials and grasses, which now unfold their splendor, are usually only divided and planted in spring.
Supporting the perennials: Above all, tall and vigorously flowering perennials such as asters now need stabilizing aids in the form of perennial supports or stable branches.

Of course, now is also a good time to plant whole new hardy perennials for next year – this is especially true for spring bloomers.
If you have a larger bed, it makes sense to create a planting plan for it.

You can also obtain seeds for the following year from seed-forming perennials.
What is not cut off is a welcome source of food for birds.
