Overview
Maxifort is not grown for its fruit; it is a vigorous interspecific hybrid rootstock onto which a favorite tomato is grafted. Its large root system resists soil-borne problems including corky root, crown rot, fusarium and verticillium wilt, and it boosts the scion's vigor, fruit size, yield and season length, which is why greenhouse and high-tunnel growers use it. Sow rootstock and scion together, graft at pencil-thick stems, heal the grafts in a humid shaded chamber for about a week, then plant out after frost with sturdy support.
