Impatiens can be propagated from cuttings or from seed.
From cuttings
- Select a non-flowering stem with at least two leaf nodes
- Cut the stem about 3–6 inches long, just below a node
- Remove all but the top two leaves Dip the cut end in rooting hormone powder or gel Insert the cutting into a pot or tray filled with potting soil, vermiculite, or perlite
- Water the soil until it’s moist but not soggy Place the pot in a bright location with indirect light
- After a couple of weeks to a month, the cutting should be rooted and ready to be moved to its final location
From seed
- Fill a tray with seed-starting mix
- Place a couple of seeds in each compartment
- Lightly cover the seeds with soil
- Mist the seeds
- Cover the tray with plastic
- Place the tray in a bright location
- Wait until the last frost has passed, then transplant the seedlings outside
Impatiens are sensitive to frost, so it’s best to wait until all danger of frost has passed before transplanting or sowing seeds.
