- Replant each section in loose soil or a container
Stem cuttings
- Take a 3–5 inch cutting from a healthy plant
- Remove the leaves from the bottom half of the stem
- Dip the cut end in rooting hormone
- Insert the cutting into a pot with potting mix
- Cover the pot with plastic wrap
- Place in indirect light and keep the soil moist
- Remove the plastic when new growth appears
Seeds
- Lightly moisten a potting mixture with peat and vermiculite
- Plant the seeds halfway into the soil
- Cover with soil
- For indoor seeds, place the pots in a freezer for up to six weeks
- Place the pots in a warm location to germinate
Bleeding heart plants grow best in USDA zones 3–9. They prefer rich, well-draining soil in partial shade.
