How to Graft a Bush of Roses of Different Colors Step by Step

Grafting roses is a wonderful way to create a single bush with blooms of different colors. This process, while requiring some precision and patience, can be done successfully by following these steps. Here’s a detailed guide to help you graft a bush of roses of different colors.

Materials Needed

  • Healthy rootstock rose bush
  • Rose scions (cuttings) from different colored roses
  • Sharp grafting knife
  • Grafting tape or rubber bands
  • Pruning shears
  • Rooting hormone (optional)
  • Clean cloth
  • Rubbing alcohol (for sterilizing tools)

Step-by-Step Instructions

1. Prepare the Rootstock

  1. Choose the Rootstock: Select a healthy, established rose bush that is well-suited to your climate and soil conditions.
  2. Sterilize Tools: Clean your grafting knife and pruning shears with rubbing alcohol to prevent disease transmission.
  3. Cut the Rootstock: Cut the rootstock stem at a slight angle, about 6-12 inches above the ground. Ensure the cut is clean and smooth.

2. Prepare the Scions

  1. Select Scions: Choose healthy rose cuttings (scions) from different colored rose bushes. Each scion should have at least 3-4 buds.
  2. Cut Scions: Cut each scion at a 45-degree angle at the base, making sure the cut is clean.
  3. Optional: Dip the cut end of each scion in rooting hormone to encourage growth.

3. Graft the Scions to the Rootstock

  1. Make a T-Cut: On the rootstock, make a vertical cut about 1-2 inches long. At the top of this cut, make a horizontal cut to create a T-shape.
  2. Open the Flap: Gently lift the bark on the rootstock at the T-cut to create a small flap.
  3. Insert the Scion: Slide the cut end of the scion under the bark flap, ensuring that the cambium layers (the green part just under the bark) of both the scion and rootstock are in contact.
  4. Secure the Graft: Wrap the grafting tape or a rubber band around the graft site to hold the scion in place. Ensure it is snug but not too tight.

4. Repeat for Multiple Scions

  1. Multiple Grafts: Repeat the grafting process for each different colored scion you want to add to the rootstock. Space the scions evenly around the rootstock for a balanced appearance.

5. Care for the Grafted Rose Bush

  1. Watering: Water the grafted rose bush thoroughly after grafting. Keep the soil consistently moist but not waterlogged.
  2. Sunlight: Ensure the grafted rose bush receives adequate sunlight, ideally 6-8 hours of direct sunlight per day.
  3. Protection: Protect the grafts from extreme weather conditions. If necessary, cover the grafts with a plastic bag to maintain humidity, but ensure there is good airflow to prevent mold.
  4. Pruning: Remove any shoots or growth from the rootstock below the grafts to ensure all the plant’s energy goes into the grafted scions.

6. Monitor Growth and Remove Grafting Tape

  1. Monitor: Regularly check the grafts for signs of growth. Successful grafts will start to produce new leaves and stems within a few weeks.
  2. Remove Tape: Once the grafts have taken and are growing well (usually after a few months), carefully remove the grafting tape or rubber bands.

7. Long-Term Care

  1. Fertilizing: Apply a balanced fertilizer to support the growth of your multi-colored rose bush.
  2. Pruning: Prune the bush annually to maintain its shape and encourage healthy growth.
  3. Pest Control: Monitor for pests and diseases, treating as necessary to keep the rose bush healthy.

By following these steps, you can create a stunning rose bush with blooms of different colors. With patience and careful attention, your grafted rose bush will flourish, adding beauty and variety to your garden.
