The Best Method: Stem Cuttings
While Geranium cinereum can be started from seed, cuttings offer a faster and more reliable route to success. This method utilizes the plant’s ability to regenerate roots from a section of stem. Here’s how to do it:
1. Timing is Everything:
The ideal time for taking cuttings is late spring to early summer when the plant is actively growing.
2. Tools of the Trade:
- Sharp, clean pruning shears or a knife
- Seedling starting mix or equal parts peat moss and perlite
- Small pots or seed trays
- Rooting hormone (optional, but recommended)
3. Taking the Cutting:
- Choose healthy, non-flowering stems that are about 3-4 inches long.
- Make a clean cut just below a leaf node (where the leaf joins the stem).
- Remove the leaves from the bottom inch of the cutting.
4. Preparing the Cutting:
- Dip the cut end into rooting hormone (optional).
- Fill your pots with the starting mix and moisten it thoroughly.
- Make a small hole in the center of each pot using a pencil.
- Gently insert the cutting into the hole, ensuring that at least one leaf node is below the soil line.
5. Encouraging Root Development:
- Place the pots in a warm, bright location out of direct sunlight.
- Maintain a humid environment by covering the pots with a plastic bag or placing them in a propagator.
- Check the soil moisture regularly and mist if needed to keep it consistently moist but not soggy.
6. The Waiting Game (and the Rewards):
- Rooting typically takes 4-6 weeks. You can gently tug on the cutting – resistance indicates roots have formed.
- Once rooted, gradually acclimate the new plants to outdoor conditions before transplanting them to their final location in the garden.
A Few Extra Tips:
- Choose young, vigorous growth for the best chance of success.
- Sterilize your cutting tools with rubbing alcohol before and after each use to prevent the spread of disease.
- Avoid overwatering as this can lead to root rot.
