Supersweet 100 is the cherry tomato that built its reputation on pure, concentrated sweetness. This indeterminate F1 hybrid produces hundreds of small, glossy red fruits over a long season, reaching maturity in just 60 days from transplant (though some sources report 70-79 days). Plants grow tall and vigorous, reaching 36 to 96 inches depending on your pruning choices, making them a favorite for trellising systems where the abundance becomes part of the garden's visual drama. It thrives in full sun with moderate water and well-balanced soil, rewarding patient gardeners with an almost continuous harvest from mid-summer through frost.

The sheer productivity of Supersweet 100 sets it apart in the cherry tomato world. A single plant can produce more fruit than most gardeners expect, with small, intensely flavored red cherries that concentrate sweetness in every bite. This variety handles a range of growing conditions from garden beds to containers and hanging baskets, and its resistance to major diseases including Early Blight, Fusarium Wilt, Late Blight, Tobacco Mosaic Virus, and Verticillium Wilt means you can focus on harvest instead of fighting infections.
Supersweet 100 cherries are perfect for fresh eating straight off the vine, where their concentrated sweetness really shines. They work beautifully in salads, halved on charcuterie boards, or roasted whole until their skins split and the insides caramelize. Their small size and prolific production also make them ideal for snacking and sharing with neighbors, and they hold up well in hanging baskets and containers where kids and guests can pick as they walk by.

Start seeds indoors about 5-6 weeks before your transplant date. Sow seeds 1/4 inch deep in flats or 200-cell trays, lightly covering them. Maintain soil temperature at 75-85°F with moderate moisture; seeds typically germinate in 5-7 days. At first true leaf emergence, pot up to 50-cell trays or 4-inch pots depending on your transplant timing. Grow seedlings at a constant 60-70°F and provide complete fertilizer until you're ready to harden them off. Avoid starting too early, as leggy, root-bound, or flowering transplants can stunt plants and delay early production.
Transplant outdoors when soil has warmed and frost danger has passed. Space plants 24 inches apart with 36 to 48 inches between rows. Harden off seedlings gradually before moving them to the garden. Don't rush transplanting; wait until they're well-established without excessive flowering, which can reduce early yields.
Pick cherries when they turn fully red and feel slightly soft to gentle pressure. They'll continue to ripen on the vine, developing more intense sweetness the longer they stay attached. You can harvest at the mature red stage for immediate eating, or pick them slightly less ripe if storing. Twist the fruit gently or snip with pruners to avoid damaging the delicate vines. The plant's prolific nature means you'll have continuous harvest opportunities from mid-summer through frost.
Since Supersweet 100 is indeterminate, it will grow indefinitely if left unpruned, reaching 36 to 96 inches tall depending on your pruning strategy. For manageable harvest and good air circulation, consider pruning once the plant outgrows a comfortable height for picking. Using the basket-weave trellising method described below works well without severe pruning. If you're growing in a smaller space or container, you can pinch off the top of the plant in late summer to redirect energy to ripening existing fruit rather than producing new growth.
