Perennial geraniums can be propagated by taking stem cuttings or dividing the plant

Stem cuttings

Select a stem: Choose a healthy stem with a growing tip. 

Cut the stem: Use clean shears or scissors to cut the stem just above a leaf node. 

Trim the leaves: Remove any lower leaves and flower buds, leaving only a few at the top. 

Root the stem: You can root the stem in water or in soil. 

In water: Place the stem in a jar of water, keeping the water fresh by changing it daily. After a few weeks, roots should develop. 

In soil: Insert the stem into a pot of compost, making sure the cutting is just below a leaf node. 

Place in a suitable location: Place the pot in a shady area with good drainage. 

Dividing the plant 

  1. Dig up the plant.
  2. Cut through the plant, separating it into clumps.
  3. Remove any dead or rotten parts.
  4. Replant the healthy clumps in the garden.

You can propagate geraniums at any time of year, but some recommend taking cuttings in early morning.
