Perennial Geraniums: How to Divide Them?

When to divide perennial geraniums?

Divide geraniums preferably in spring, in April or May. We recommend doing this when the clumps become bare in the centre, to rejuvenate them, starting from the fifth or even eighth year of cultivation depending on the variety. If you notice your young plants spreading too much or becoming exhausted, don’t hesitate to divide them more frequently.

How to divide them?

1. Dig up the plant using a garden fork. Remove excess soil around the roots.
2. Then divide the clump with a large knife, secateurs or by hand. For Geranium ‘Rozanne’, you’ll need to gently untangle the roots to obtain several young plants.
3. Separate the young shoots, ensuring each has sufficient roots.
4. Prepare the ground and dig a planting hole.
5. Add some compost
6. Plant the new clumps, backfill with soil around them, then firm gently.
7. Water thoroughly.

Continue watering in the following weeks.

Depending on the variety, you can also divide the clump directly in the ground with a spade, digging up only the sections you wish to replant in your desired location.
