Amai Tomato is a highly productive F1 hybrid grape tomato bred for controlled growing environments like greenhouses and tunnels, where it reaches full maturity in just 58 days from transplant. Its compact, indeterminate growth habit and strong disease resistance to Fusarium Wilt, Gray Leaf Spot, leaf mold, and nematodes make it a reliable choice for growers managing multiple health pressures. This variety thrives in structured growing systems where temperature control and vertical training unlock its full potential for season-long productivity.

Amai Tomato delivers rapid production in greenhouse conditions, maturing in under 60 days from transplant and producing abundant grape-sized fruit on a single vigorous vine. Its resistance to four major tomato diseases, combined with leaf mold resistance specifically noted for controlled environments, removes many barriers to continuous harvesting. The variety's responsiveness to temperature management and trellising techniques means gardeners can actively steer toward maximum yields by adjusting night temperatures down to 62-66°F at fruit set.
As a grape tomato bred for greenhouse production, Amai is harvested primarily for fresh eating and can be picked in clusters (truss harvesting) for market presentation. Its small, uniform fruit size suits snacking, salads, and any preparation where individual grape tomatoes are valued for their texture and ease of handling.

Sow seeds indoors at 73-77°F (23-25°C) and plan for 6-7 weeks of development before transplanting. Provide supplemental lighting to maintain vigorous seedlings during indoor growing, especially if starting early to extend the harvest season.
Transplant into greenhouse or tunnel environment 6-7 weeks after sowing. For 5-7 days after transplanting, maintain 73-77°F (23-25°C) day and night temperatures to promote rapid foliar and root growth. Space plants allowing 4-6 square feet of growing area per leader, adjusting based on your climate, disease pressure, and chosen pruning method. Plant deeply as you would field tomatoes, unless the plant is grafted, in which case position the graft union above soil level.
Amai reaches maturity 58 days after transplanting. Harvest fruit at full color for peak flavor and sweetness. This variety supports truss harvesting, meaning you can pick entire clusters of fruit together, which is useful for market presentation and labor efficiency. Harvest regularly to encourage continued flowering and fruit production throughout the season.
Train Amai to 1-2 branchless leaders onto separate vertical strings, using trellis clips positioned roughly 1 inch below every third leaf. Keep strings taut and reuse the bottom clips, maintaining at least 3-4 clips per string. Selectively prune leaves and flower clusters to manage diseases and steer the plant toward season-long productivity rather than early fruit oversetting. If using a lower-and-lean system (a method suited to long-season growing with adequate labor and sturdy structures), carefully lower vines horizontally along the trellis to rejuvenate branching and extend harvest. Remove scion roots that may emerge from grafted plants, and keep the rootstock free from suckers.
