What To Know
- Keep the cuttings in a warm, humid environment, such as a greenhouse or covered container.
- Place the cuttings in a cool, dry location for several weeks to allow them to develop a callus.
- Plant the callused cuttings in a well-draining potting mix, burying two-thirds of the cutting.
Ribes sanguineum, commonly known as the flowering currant, is a beloved ornamental shrub renowned for its vibrant blooms and attractive foliage. Propagating this captivating plant is a rewarding endeavor, allowing you to share its beauty with others or expand your own garden. In this comprehensive guide, we will delve into the various methods of propagating ribes sanguineum, providing you with all the knowledge and techniques you need to succeed.
Seed Propagation
While possible, seed propagation is not the most common method for ribes sanguineum. However, if you wish to pursue this route, follow these steps:
1. Collect ripe berries: Gather fully ripened berries from healthy plants.
2. Extract seeds: Mash the berries to extract the seeds and rinse them thoroughly.
3. Stratify seeds: Place the seeds in a moist medium, such as vermiculite or peat moss, and refrigerate for 60-90 days.
4. Sow seeds: Sow the stratified seeds in a well-draining seed starting mix and keep them moist.
5. Provide light: Place the seeds in a location with bright, indirect light.
6. Germination: Germination can take several months, so be patient.
Softwood Cuttings
Softwood cuttings provide a reliable method for propagating ribes sanguineum. Here’s how:
1. Take cuttings: In late spring or early summer, take 4-6 inch cuttings from non-flowering shoots.
2. Prepare cuttings: Remove any leaves from the bottom half of the cutting and dip the base in rooting hormone.
3. Plant cuttings: Insert the cuttings into a well-draining potting mix, ensuring the rooting hormone area is covered.
4. Water and mist: Water the cuttings and mist them regularly to maintain humidity.
5. Provide warmth: Keep the cuttings in a warm, humid environment, such as a greenhouse or covered container.
6. Rooting: Roots should form within 4-6 weeks.
Hardwood Cuttings
Hardwood cuttings are another viable option for propagating ribes sanguineum. Follow these steps:
1. Take cuttings: In late fall or early winter, take 6-12 inch cuttings from dormant plants.
2. Prepare cuttings: Remove any leaves and cut the bottom of the cuttings at an angle.
3. Callus cuttings: Place the cuttings in a cool, dry location for several weeks to allow them to develop a callus.
4. Plant cuttings: Plant the callused cuttings in a well-draining potting mix, burying two-thirds of the cutting.
5. Protect cuttings: Mulch around the cuttings to protect them from cold and dehydration.
6. Rooting: Roots will form in spring.
Layering
Layering is a simple and effective method for propagating ribes sanguineum. Here’s how:
1. Choose a branch: Select a healthy branch that is close to the ground.
2. Prepare the branch: Make a shallow incision on the underside of the branch about 6 inches from the tip.
3. Bend the branch: Bend the branch down and secure it in place with a U-shaped pin or wire.
4. Cover the incision: Cover the incision with moist soil or peat moss and keep it moist.
5. Rooting: Roots should form at the incision within 6-12 months.
Division
Division is a quick and easy way to propagate ribes sanguineum, especially for established plants. Follow these steps:
1. Dig up the plant: Carefully dig up the entire plant in spring or fall.
2. Divide the root ball: Use a sharp knife or spade to divide the root ball into several smaller sections.
3. Replant divisions: Replant the divisions immediately in well-draining soil.
4. Water deeply: Water the divisions deeply to settle the soil around the roots.
Grafting
Grafting is a more advanced technique that can be used to propagate ribes sanguineum onto other rootstocks. Here’s how:
1. Prepare the rootstock: Select a healthy rootstock that is compatible with ribes sanguineum.
2. Prepare the scion: Take a 4-6 inch cutting from a healthy ribes sanguineum plant.
3. Make the graft: Make a T-shaped incision on the rootstock and insert the scion into the incision.
4. Secure the graft: Wrap the graft union with grafting tape or wax.
5. Care for the graft: Keep the graft union moist and protected from the elements.
Finishing Up: Tips for Success
- Use sharp, clean tools to prevent disease.
- Keep the cuttings or divisions moist but not soggy.
- Provide adequate light and warmth for cuttings.
- Protect newly propagated plants from harsh weather conditions.
- Be patient, as propagation can take time.
