TY Yellow Mimi is a compact F1 hybrid tomato bred for controlled environments, delivering ripe fruit in just 60 days from transplant. This indeterminate vine produces small, golden-yellow tomatoes with improved disease resistance, thriving in hardiness zones 3 through 11. Its efficiency in tunnels and greenhouses makes it a smart choice for growers seeking early, reliable harvests with minimal disease pressure.

Small golden fruits ripen fast from transplants, reaching harvest in 60 days under the right conditions. The variety was developed with greenhouse production in mind, responding beautifully to trellising and pruned training systems that maximize light and air circulation. Its resistance to Leafmold, Nematodes, Tomato Spotted Wilt Virus, and Tomato Yellow Leaf Curl Virus means you'll spend less time troubleshooting and more time harvesting.
TY Yellow Mimi's small, bright fruits work wonderfully as snacking tomatoes straight off the vine, adding visual pop to salads and charcuterie boards. The compact size and uniform ripening also make them suited to truss harvesting, a technique particularly valuable in commercial greenhouse settings where presentation matters.

Start seeds indoors 6 to 7 weeks before your transplant date, maintaining soil temperatures between 73 and 77 degrees Fahrenheit for strong germination. Provide supplemental lighting to keep seedlings compact and vigorous, as adequate light prevents the leggy growth common in shorter daylight periods.
Transplant seedlings outdoors after the last frost date for your zone, planting deeply as you would field tomatoes (unless grafted, in which case position the union above soil). Maintain day and night temperatures at 73 to 77 degrees Fahrenheit for the first 5 to 7 days after transplanting to promote rapid root and foliage development.
Harvest ripe yellow fruits at full color, typically 60 days after transplanting under ideal greenhouse or tunnel conditions. Watch for fruits that yield slightly to gentle pressure and have fully developed their golden hue. Consider truss harvesting by removing entire clusters at once, a technique that streamlines picking and maintains fruit presentation.
Train the indeterminate vine to 1 to 2 branchless leaders, securing each to separate vertical strings with trellis clips spaced roughly 1 inch below every third leaf. Keep strings taut and reuse bottom clips, maintaining at least 3 to 4 clips per string to support the growing plant. Selectively prune leaves and flower clusters to improve air circulation, manage disease pressure, and maximize fruit production across the season. If using a lower-and-lean system on a long-season structure with adequate labor, adjust accordingly.
