Grafting roses is a simple yet rewarding way to create a rose bush with multiple flower colors. It’s a technique where a rose of a desired color (the scion) is grafted onto a healthy, strong rootstock. The process is commonly used by gardeners to combine the best traits of different rose varieties, such as vibrant colors and sturdy growth. If done correctly, you can enjoy multiple colors on a single bush, or even revitalize a plant with a less-than-healthy rootstock.
Best Time to Graft Roses
Timing is crucial when grafting roses. The best time to graft is during the summer when the plant’s sap is flowing vigorously. This ensures that the plant is actively growing, which helps the graft take successfully. Look for a period when your roses are growing rapidly and appear healthy. This timing helps ensure that your grafting efforts will have the best chance of success.
Step-by-Step Grafting Instructions
- Prepare the Tools
Start by sanitizing your knife or cutting tool with rubbing alcohol. This is an essential step to prevent the spread of diseases that could affect your roses.- Collect Scions (Cuttings)
Select healthy rose stems from the color variety you want to graft. Use a sharp knife to cut a section with three buds. Measure two buds from the bottom and make the cut above the third one. These buds will eventually develop into flowers. - Shape the Scion
Using a utility knife, carve a “V” shape at the bottom of the scion. This will allow it to fit neatly into the rootstock and improve the chances of a successful graft. - Prepare the Rootstock
Select a healthy, biennial rose plant as the rootstock. Avoid using new growth, as it’s less likely to support a successful graft. Trim the top of the rootstock and make a vertical cut about one centimeter deep in the center of the stem. - Insert the Scion
Carefully place the V-shaped end of the scion into the cut made on the rootstock. The two stems should align so that the cambium layers (the tissue just under the bark) of both the scion and rootstock make contact. Secure the graft by wrapping it tightly with grafting tape. Leave the graft to settle for about four to six weeks. You can repeat this process to graft more scions onto the same rootstock.
Post-Grafting Care
- Watering: Keep the grafted plants well-watered, ensuring the soil stays moist for the first 15 days. This helps the grafts establish strong roots and grow successfully.
- Trimming: Trim any shoots that appear on the rootstock for the first few weeks, especially the first 2-4 shoots. This encourages the scion to grow more vigorously by focusing energy on the graft.
- Remove the Tape: As the graft begins to take and new growth appears, you can remove the adhesive tape. Be gentle to avoid damaging the new graft.
- General Care: Ensure that the grafted rose plant receives ample sunlight, space, and air circulation to thrive. Regular care with compost and organic matter can help boost the plant’s health and flowering potential.
With proper care, your grafted roses will eventually bloom with the colors you’ve chosen, allowing you to enjoy a vibrant, multicolored rose bush. Happy grafting!
