Cranesbills differ not only in terms of their preferred locations depending on the species, but also in terms of the best way of propagation. With the exception of hybrids, almost all cranesbill species can be propagated by seed without any problems, but propagation by cuttings or, in the case of older specimens, by division is also possible. You can find out which species are particularly suitable for this type of propagation and how it is carried out in the following article.

The cranesbill can be best multiplied by division

Divide cranesbill - Here's how

In the case of perennial perennials - including cranesbills - propagation by division is an uncomplicated and tried-and-tested method, which also has the advantage of rejuvenating older plants and thus extending their lifespan as well as stimulating their growth and flowering. And this is how the division of a cranesbill succeeds:

  • Depending on the species, the optimal time is in spring or summer.
  • Using a digging fork, dig up the entire plant.
  • Be careful not to crush or otherwise damage the roots unnecessarily.
  • Thoroughly shake the soil off the rootstock.
  • Now divide it into at least two (but also more) individual pieces.
  • You can use sharp scissors, a knife or even a spade.
  • Make sure that each section has at least one shoot with strong roots on it.

You can then plant the freshly divided cranesbills in the previously determined location or in a planter. Water the plants thoroughly until they have taken root and are successfully established.

Geranium species suitable for propagation by division

The following cranesbill species are suitable for vegetative propagation by division:

  • Cambridge cranesbill (Geranium cantabrigiense), division in spring
  • Gray cranesbill (Geranium cinereum), division in spring
  • Clarke's cranesbill (Geranium clarkei), dividing the rhizomes in summer
  • Hybrid "Rozanne", division in spring
  • Himalayan cranesbill (Geranium himalayense), division in spring
  • Heart-leaved cranesbill (Geranium ibericum), division in spring
  • Rock cranesbill (Geranium macrorrhizum), division in spring
  • Magnificent cranesbill (Geranium magnificum), propagation exclusively by division in spring
  • Oxford cranesbill (Geranium oxonianum), propagation by division in spring
  • Cranesbill (Geranium phaeum), division in spring
  • Caucasian cranesbill (Geranium renardii), division in spring
  • Blood-red cranesbill (Geranium sanguineum), division in spring
  • Siberian cranesbill (Geranium wlassovianum), division in spring


Moisture is a crucial factor for both root formation and root growth. Therefore, the freshly divided plants must be watered regularly. However, it is better to use a protective hood made of plastic (e.g. a cut-off plastic bottle is ideal) or a glass bell to create compressed air and thus high humidity. But in any case, you need to avoid excessive moisture so that rot does not develop.
