If the plant shoots in the same place for many years, over time, the inflorescences will begin to shrink. This is due to soil depletion and some other factors, therefore, Astilba is recommended to be repotted periodically. New shoots will appear quickly, usually there are no problems with rooting.

Reproduction of Astilba Ardens

Reproduction of Astilba Ardens

This plant can multiply by seed or vegetatively. The first option is more often used in selective breeding, since it allows you to get non-standard color options for inflorescences. In addition, seeds can be grown to seedling condition before being moved outdoors.

If seed cultivation is supposed, mandatory stratification of the material is carried out before sowing: the seeds must be kept at zero temperature, this will significantly improve germination.

For seedlings, seeds are sown in February or early March, the first shoots will appear in 2-3 weeks, while sowing must be carried out without deepening the seeds into the soil. In early summer, the sprouts can be transplanted into open ground. If it is planned to sow seeds directly into open ground, then it is carried out before winter, and the first shoots will appear in the spring.

Vegetative propagation of the bush is much easier. The shrub is usually divided either in early summer or in August, at the end of the flowering period.

Basic transplant rules:

  • The rhizome is divided into several parts with a knife or garden shovel. Growth will begin at the expense of its upper parts, so the lower parts of the rhizome can be removed.
  • You need to transplant shoots right away after dividing the bushotherwise the roots may dry out.
  • Shoots with parts of the rhizome are placed in a soil consisting of sod land, peat and coarse sand. At the base of the kidney, it is necessary to compact the soil.
  • The transplanted plant must be placed in a shaded area, complete rooting will occur in about two to three weeks. This requires moderate but regular watering.
  • When transplanted correctly, the divided plant will very quickly begin to produce young shoots.
  • Astilba Ardens tolerates a transplant, and it will only benefit her.
  • Stronger peduncles appear on young shoots, so the inflorescences will be larger and brighter.
  • Experienced gardeners advise transplanting every few years to avoid inflorescences becoming smaller.

In general, Astilba Ardens remains an unpretentious plant for which you can quickly find a suitable place on the site. The bush will delight the eye with a lush constant flowering, it can become a real decoration any adjoining territory.
