Granadero is a prolific F1 hybrid plum tomato that delivers consistent harvests just 75 days from transplant. Its indeterminate growth habit means it will keep producing fruit throughout the season, rewarding patient gardeners with waves of compact, flavorful tomatoes. This variety thrives in moderately fertile soil with a pH between 6.0 and 6.8, and it handles moderate water needs efficiently. If you're looking for a reliable producer that doesn't demand constant fussing, Granadero offers both productivity and straightforward care.

As one of the most prolific plum tomatoes available, Granadero demonstrates remarkable consistency across seasons and growing conditions. The F1 hybrid vigor ensures vigorous growth and disease resistance to Fusarium Wilt, Verticillium Wilt, Nematodes, and Tomato Spotted Wilt Virus, which collectively protect against many of the threats that derail tomato gardens. Its 75-day maturity from transplants means you'll be harvesting by mid-summer in most climates, making it a reliable choice for short-season gardeners and those seeking quick results.
Granadero's plum tomato form makes it exceptionally suited to sauces, paste, and cooking applications where flesh-to-seed ratio matters. The compact fruit dries well and holds its shape through processing, which is why commercial growers and home canners alike favor this type. Fresh eating is also rewarding, especially when harvested at full ripeness and enjoyed soon after picking.

Sow seeds 1/4 inch deep about 5 to 6 weeks before your transplant date. Use 20-row flats with 20 seeds per row, or 200-cell trays with 1 seed per cell, lightly covering the seeds. Maintain soil temperature at 75 to 85°F with moderate moisture; seeds typically germinate in 5 to 7 days. Once first true leaves appear, pot seedlings into 50-cell trays or 4-inch pots depending on your expected transplant timing. Grow at a constant 60 to 70°F and apply complete fertilizer until the seedlings are hardened off. Avoid starting too early; leggy, root-bound, or already-flowering transplants will cause stunting and reduce early production.
Transplant outdoors after hardening off, spacing plants 24 inches apart with 48 inches between rows. Wait until soil temperatures are warm and frost danger has passed, as Granadero is half-hardy and will not survive frost. Set transplants at the same depth they were growing in their pots, or slightly deeper if they are leggy; bury part of the stem to encourage additional root development.
Pick fruit when fully ripe and deep red in color, which signals peak sugar and acid balance. Granadero fruits are plum-shaped and compact; harvest by gently twisting and lifting or using pruners to cleanly detach the fruit. For storage, pick near-ripe rather than fully vine-ripe fruit if you need to keep tomatoes for a few days; fully ripe fruit is best used immediately.
Since Granadero is indeterminate, it will grow continuously throughout the season. For tall indeterminates, consider short extensions on your trellising or begin pruning once vines outgrow a manageable height for easy harvesting and maintenance. Remove lower leaves as the plant grows to improve air circulation and reduce disease pressure, but avoid aggressive pruning that removes too much foliage and exposes fruit to sunscald.
