How to Graft an Apple Tree
Grafting is an excellent technique for propagating apple trees that involves combining two different parts of apple trees to form a new one. This process allows you to preserve desirable traits, such as flavor, size, or resistance to disease, while improving the overall performance of the tree. In this article, we’ll walk you through the steps needed to graft an apple tree successfully.
1. Select the right materials:
First and foremost, choose a healthy and disease-free rootstock and scion. The rootstock is the lower part of the graft and determines the overall size and vigor of the tree. The scion is the upper part of the graft taken from a desired variety with properties you want to preserve in your new tree.
2. Gather your tools:
You will need the following tools for grafting:
– A sharp grafting knife
– Pruning shears
– Rubber bands or twine
– Grafting tape or parafilm wrap
– Grafting wax or sealant
3. Prepare the rootstock:
To prepare your chosen rootstock, trim it down to a fresh cut using pruning shears at about 10 inches above ground level. Next, make a vertical cut in its center approximately 1 inch deep using your grafting knife.
4. Prepare the scion:
Choose a pencil-sized scion with 2-3 well-developed buds on it. Make a 1-inch long sloping cut on one end that mirrors the angle of your rootstock’s vertical cut. Afterward, create a small ‘tongue’ by making a shallow upward cut at the base of your initial slanting cut.
5. Join the rootstock and scion:
Align both pieces such that their sloping cuts overlap and their ‘tongues’ interlock securely. Press firmly on them so they fit together snugly. The cambium layers of both parts should also be in close contact to ensure successful growth.
6. Secure the graft:
Wrap the graft union tightly using grafting tape, parafilm wrap, or even a small plastic bag for protection against air exposure. Then, use rubber bands or twine to hold the two parts firmly together.
7. Apply wax or sealant:
Depending on your preference, coat the entire graft area with grafting wax or sealant, ensuring all cuts and joints are covered. This step prevents moisture loss and shields the graft from external elements.
8. Care for the grafted tree:
Place your newly grafted tree in a sheltered and shaded location for a few weeks as it heals. Regularly check if there are any signs of drying or dying tissues. Remove any suckers that sprout from the rootstock to direct energy into the new graft union.
9. Monitor growth:
As the graft begins to grow, secure it with tree ties and stakes as needed to give proper support. On successful healing, expect your new apple tree to start producing fruit within a few years.
In conclusion, grafting is an effective method of strengthening apple trees while preserving preferred characteristics. With patience and some practice, you’ll be able to create new apple trees with ease that thrive in your garden and provide delightful fruit for years to come.
