Bougainvilleas are renowned for their vibrant and colorful blooms, making them a favorite choice for adding a splash of color to gardens and landscapes. Imagine having a single trunk bearing bougainvillea flowers in four different hues – an eye-catching spectacle indeed! With a simple grafting technique using papaya resin, you can achieve this stunning effect effortlessly. Here’s how:

  1. Selecting Bougainvillea Varieties: Begin by choosing four different bougainvillea varieties, each with distinct flower colors. Select varieties that are compatible with grafting and have similar growth habits to ensure successful grafting.
  2. Preparing the Rootstock: Choose a healthy bougainvillea plant with a sturdy trunk as your rootstock. Trim any excess foliage and branches from the trunk, leaving a clean, smooth surface for grafting.
  3. Selecting Scion Cuttings: Take scion cuttings from each of the four bougainvillea varieties, ensuring they are about the same diameter as the rootstock trunk. Trim the scion cuttings to include a small portion of stem with several leaf nodes.
  4. Applying Papaya Resin: Prepare papaya resin by collecting sap from a papaya tree or using commercially available papaya resin. Apply a thin layer of papaya resin to the cut end of each scion cutting and to the corresponding area on the rootstock trunk.
  5. Grafting the Scion Cuttings: Carefully position each scion cutting onto the rootstock trunk, aligning the cambium layers (the green inner layer just beneath the bark) of the scion and rootstock. Secure the scion cuttings in place with grafting tape or strips of cloth.
  6. Providing Proper Care: Place the grafted bougainvillea plant in a warm, humid environment with indirect sunlight. Keep the soil consistently moist but not waterlogged, and avoid exposing the graft site to direct sunlight until the graft has healed.
  7. Monitoring Growth: Over the next few weeks, monitor the grafted bougainvillea plant for signs of new growth. Once you see new leaves emerging from the scion cuttings, it indicates that the grafting has been successful.
  8. Training and Pruning: As the grafted bougainvillea plant grows, train and prune it as needed to maintain a balanced shape and encourage healthy growth. You may need to provide support for the growing branches until they become well-established.
  9. Enjoying the Spectacle: Before long, your grafted bougainvillea plant will develop into a stunning specimen, adorned with flowers in four different colors on a single trunk. Place it in a prominent location in your garden or patio, and enjoy the breathtaking display of colors throughout the blooming season.

By grafting bougainvillea varieties onto a single trunk using papaya resin, you can create a unique and visually striking focal point in your garden. Follow these simple steps, and you’ll soon be marveling at the beauty of your four-color bougainvillea pot.
