6 Steps for Propagating Buttercup Winter Hazel Plant
Propagating Buttercup Winter Hazel (Corylopsis pauciflora) can be done through either softwood cuttings or layering. Here’s a step-by-step guide for both methods:
Method 1: Softwood Cuttings
Softwood cuttings are taken from the current season’s growth and are best done in early summer.
Step 1: Select and Prepare the Cutting
- Choose the Cutting: Select a healthy, non-flowering shoot from the current season’s growth. The cutting should be about 4-6 inches long.
- Cut the Stem: Using clean, sharp pruners or scissors, make a cut just below a node (where the leaf meets the stem).
- Remove Lower Leaves: Strip off the leaves from the lower half of the cutting, leaving a few leaves at the top.
Step 2: Prepare the Planting Medium
- Select the Medium: Use a well-draining potting mix or a mixture of perlite and peat moss.
- Fill the Pot: Fill a small pot or container with the prepared medium, leaving about an inch from the top.
Step 3: Plant the Cutting
- Dip in Rooting Hormone (Optional): Dip the cut end of the stem into rooting hormone powder to encourage root growth.
- Insert the Cutting: Make a hole in the soil with a pencil or your finger and insert the cutting about halfway into the soil.
- Firm the Soil: Gently press the soil around the cutting to hold it in place.
Step 4: Create a Humid Environment
- Cover the Cutting: Place a clear plastic bag or a cloche over the pot to create a humid environment, essential for root development.
- Keep in Shade: Place the pot in a shaded, warm area, avoiding direct sunlight.
Step 5: Care and Maintenance
- Watering: Keep the soil moist but not waterlogged. Check regularly to ensure the cutting doesn’t dry out.
- Check for Roots: After about 4-6 weeks, gently tug on the cutting. If you feel resistance, roots have developed.
Step 6: Transplanting
- Harden Off: Once roots have developed, gradually acclimate the young plant to outdoor conditions by placing it outside for a few hours each day.
- Transplant: After a few weeks, transplant the cutting into the garden or a larger pot, ensuring it’s placed in a location with partial shade and well-draining soil.
Method 2: Layering
Layering involves bending a low branch to the ground and encouraging it to root while still attached to the parent plant. This method is usually done in the fall.
Step 1: Select the Branch
- Choose a Low Branch: Select a healthy, flexible branch that is close to the ground and can be easily bent down.
Step 2: Prepare the Branch
- Wound the Stem: Slightly wound the underside of the branch where it will touch the soil by making a small cut or scraping off some bark to expose the cambium layer.
- Apply Rooting Hormone (Optional): Dust the wounded area with rooting hormone to encourage root development.
Step 3: Secure the Branch
- Bend and Bury: Bend the branch down to the ground, and bury the wounded section about 2-3 inches deep in the soil.
- Secure in Place: Use a garden staple, wire, or a small rock to hold the branch in place so it stays buried.
Step 4: Care for the Layered Branch
- Watering: Keep the soil around the buried section moist but not soggy. The branch should stay in place throughout the winter.
- Check for Roots: After several months, usually by the next growing season, roots should form where the branch was buried.
Step 5: Transplanting
- Sever the New Plant: Once the new roots have developed, sever the branch from the parent plant with clean pruners.
- Transplant: Dig up the rooted section carefully and transplant it to its new location in the garden, ensuring it receives the same care as the parent plant.
By following these steps, you can successfully propagate Buttercup Winter Hazel, allowing you to enjoy more of these beautiful shrubs in your garden or share them with others.
