What is a grafted tomato plant? A grafted tomato plant is actually two plants that are spliced or grafted together just above the soil line. What happens is the grower selects a tomato plant that has a superior, vigorous and disease resistant root system and cuts the plant off from the roots. They then select a variety of tomato plant that is known for producing flavorful fruit that the consumer wants and cut the roots off from the plant. They take the best features of both plants and graft them together to make super tomato plant. Grafted tomato plants produce about twice the amount of tomatoes than a conventional plant of the same variety.
In the past, grafted tomato plants were very expensive but the prices have come down quite a bit recently. They still cost about twice as much as a conventional tomato plant. So why pay twice as much for twice the yield? Why not just buy two regular tomato plants? Think about all the stuff you have bought in the past to grow your tomatoes. Raised beds or pots, special soil, special cages, fertilizers, lime, sprays, those upside down hanging things, etc. With a grafted tomato, you’ll need some decent garden soil and a stake to tie it to as it grows. It’ll probably save you a bit of money to buy a superior plant in the first place.
The larger root stock allows the plant grow to its full potential even in imperfect soil conditions. Your tomato plant will grow larger, resist disease and provide many more delicious tomatoes than you’ve ever seen before. It isn’t uncommon to see a grafted tomato have doubled the yield of a conventional tomato of the same variety. As the saying goes, “More root, more fruit!” The only precaution is that you can’t plant it deep like you can a regular tomato plant. You have to keep the graft above the soil line. Deep planting is a way to get a regular tomato plant to develop extra roots at a faster pace. Since the grafted tomato is designed to do that naturally, deep planting is not necessary.
