There are many reasons to propagate your own garden plants, but the desire for more plants is not always the underlying reason. Sometimes it is also a matter of rejuvenating older plants and maintaining or stimulating the willingness to flower again.

After flowering, the seeds of the astilbe can be collected for propagation

This is also a reason for the division of the root ball of the Astilbe. At the latest when the plant is only flowering weakly or moderately, you should resort to this remedy. Alternatively, you can regularly divide your pierogi every three to five years.

propagation by division

To do this, dig out the root ball of your astilbe, divide it into several parts with a spade and replant them. The pieces should be at least the size of a fist and the individual roots should be undamaged if possible. Put some well-rotted compost in the planting holes so that the new perennials grow well.

The distance between the new plants should be about 40 to 60 cm for tall varieties, about 20 to 25 cm for small varieties, especially if they are used as ground cover.

Propagation by cuttings

The Astilbe reproduces independently through rhizomes. That's why it should be shared occasionally. Otherwise she will age. But you can also use the rhizomes themselves for propagation. But only use the fresh shoots for this, not those that are already lignified.

Cut off some strong rhizomes that already have several offshoots and plant them in the new location. However, they must not be planted too deep in the ground. Enrich the potting soil with some compost so your cuttings get enough nutrients.

Sow astilbes

You can also sow astilbes, but rearing them is not easy. During the germination period, the seeds need high humidity and temperatures of 22 - 25 °C. Although astilbes germinate in the light, the seeds do not tolerate direct sunlight. When the first leaves appear, lower the temperature and humidity.

Some propagation tips:

  • Root division promotes flowering
  • light germinator
  • Sowing a bit complicated

tips

If your Astilbe is no longer blooming, rejuvenate the perennial by dividing it.
