Grafted tomatoes are produced when two tomato plants joined together.
The resulting plant exhibits the strengths of both its “parents.”
While grafting has long been a common horticultural practice, in recent years it has become a valuable technique in tomato disease management. Usually, at least one of the tomato varieties selected for the graft has outstanding disease resistance, most often a hybrid.
Tomatoes from grafts have been regularly produced in European and Asian greenhouses. Their popularity in the U.S. is on the rise.
(Check out different varieties of grafted tomatoes.)
One tomato’s roots are used and another tomato’s body is used for the graft.
Tube grafting (or Japanese top-grafting): a fairly new technique that produces large numbers of plants quickly. Seedling rootstock and scion are severed and reattached with a clip during healing.
Cleft grafting: a V-shape in rootstock and wedge-shaped in the scion are held together with a clip during healing.
Approach grafting: notches on two stems held together with a clip during healing.
Micrografting: a new technique used primarily with hybrid tomatoes. Very tiny scions are grafted onto 3-week-old rootstock.
Several vendors offer grafted tomato plants.
