Growing Bleeding Heart Glory Bower from Seed
- Soak seeds overnight in warm or room-temperature water.
- Fill small seed trays or pots with a well-draining potting mix.
- Poke a hole about 1/2 inch deep and place the soaked seeds in the hole
- Cover with more potting mix, ensuring good soil contact.
- Mist the soil with water or bottom water to moisten the soil
- Place the seed trays or pots in a warm location with bright, indirect sunlight.
- Maintain a temperature between 70°F to 80°F for successful germination.
- Keep the soil consistently moist but not waterlogged.
Germination typically takes up to 4 weeks. Once the seedlings emerge, provide them with bright, indirect light.
Once the seedlings develop a few sets of true leaves, carefully transplant them into individual pots filled with well-draining potting mix.
Provide bright, indirect light and maintain adequate moisture levels.
Gradually acclimate the seedlings to outdoor conditions if you plan to grow them in the garden.
Growing Bleeding Heart Glory Bower from Cuttings
Bleeding Heart Vine is easier to grow from cuttings. Cuttings are best taken during the spring or early summer.
- Choose healthy, non-flowering stems from an established Clerodendrum thomsoniae plant.
- Using clean, sharp pruning shears or a knife, make a diagonal cut just below a node.
- Dip the cut ends of the cuttings in a rooting hormone powder to encourage root development.
- Insert the cuttings into a container filled with a well-draining rooting medium, such as a mix of perlite and peat moss.
- Mist the medium and cover the container with a plastic bag or use a propagator to create a humid environment.
- Place the container in a warm location with bright, indirect light. Maintain a temperature of around 70°F to 80°F (21°C to 27°C).
- Keep the rooting medium consistently moist but avoid overwatering.
After 6 to 8 weeks, gently tug on the cuttings to check for resistance, indicating the development of roots.
Once rooted, transplant the cuttings into individual pots filled with well-draining potting mix.
Provide bright, indirect light and gradually acclimate the plants to outdoor conditions if desired.
