Introduction

Grafting is a useful technique for propagating olive trees. Whether you want to create a new variety or rejuvenate an old tree, grafting can help you achieve your goals. In this step-by-step guide, we will walk you through the process of grafting an olive tree successfully. Let's get started!

What is Grafting?

Grafting is a horticultural technique that involves combining the tissues of two plants to grow as one. In the case of olive trees, grafting allows you to cultivate desirable characteristics on an existing rootstock or to create new varieties by merging different olive cultivars.

What are the Tools Needed?

Before you begin grafting an olive tree, gather the following tools:

  • Grafting knife
  • Grafting tape or rubber bands
  • Grafting wax or sealing compound
  • Rootstock olive tree
  • Scionwood from desired olive cultivar

Step 1: Selecting the Scionwood

The scionwood is the part of the desired olive cultivar that will be grafted onto the rootstock. Look for healthy, disease-free branches with at least two buds. Collect scionwood during the dormant season when the tree is in its most inactive state.

Step 2: Preparing the Rootstock

Prepare the rootstock olive tree by trimming it to the desired height. Make a vertical cut about 2 inches long on the rootstock's side, about 4 inches above the soil. This will serve as the "cleft" for inserting the scionwood.

Step 3: Preparing the Scionwood

Trim the scionwood to a length of 3-4 inches. Cut the bottom end at an angle, shaped like a wedge, making sure it matches the size of the cleft on the rootstock's side.

Step 4: Grafting

Insert the scionwood into the cleft of the rootstock, aligning the cambium layers as closely as possible. The cambium (greenish layer just beneath the bark) must make contact for successful grafting. Use grafting tape or rubber bands to secure the scionwood in place.

Step 5: Sealing the Graft

Apply grafting wax or sealing compound to the grafted area to prevent moisture loss and protect the graft from infections. Make sure to cover the entire grafted area, leaving no exposed surfaces.

Step 6: Aftercare

Once the grafting is complete, provide proper care to ensure graft success. Keep the grafted olive tree in a sheltered, partially shaded area for the first few weeks. Ensure the soil remains adequately moist but avoid overwatering.

Grafting an olive tree is an excellent way to propagate new varieties or rejuvenate existing trees. By following this step-by-step guide, you can successfully graft an olive tree and enjoy the fruits of your labor for years to come. Happy grafting!
