What are some successful grafting techniques for tomato plants?
When it comes to tomato plant grafting, there are several successful techniques that gardeners can employ to achieve optimal results. Here are some tried-and-tested grafting techniques for tomato plants:
Cleft Graft: This technique involves making a vertical slit in the rootstock, typically 1-2 inches long. Then, a matching wedge-shaped cut is made on the scion, and it is carefully inserted into the cleft of the rootstock. The key is to align the cambium layers of the rootstock and scion for successful fusion.
Tube Graft: In this method, a tube-shaped incision is made in the rootstock, approximately 1-2 inches long. The scion, prepared with a matching cylindrical shape, is inserted into the tube-like opening. The tube graft technique provides good contact between the rootstock and scion, facilitating successful graft union.
Approach Graft: This technique involves joining the rootstock and scion by aligning their stems in a side-by-side manner. The bark of both stems is removed on one side, and the exposed surfaces are tightly bound together with grafting tape or rubber bands. Over time, the cambium layers fuse, creating a unified plant.
Whip-and-Tongue Graft: This grafting technique is more advanced and requires precision. It involves making diagonal cuts on both the rootstock and scion, creating matching tongues and grooves. The two plant parts are fitted together, ensuring the tongues interlock. Grafting tape is used to secure the union tightly.
Side Graft: In this technique, a small slice is made on the side of the rootstock stem, and a corresponding cut is made on the scion. The two plant parts are then carefully joined, aligning their cambium layers, and securely wrapped with grafting tape.
