Buffalosun is an indeterminate tomato that delivers the first truly ripe, juicy tomatoes of summer in just 80 to 85 days. This variety thrives across hardiness zones 3 through 11, making it accessible to gardeners in nearly every climate. It requires full sun, moderate water, and soil pH between 5.5 and 7.0. Its long vining habit means you'll want sturdy support, but the payoff is a sustained harvest of flavorful fruit throughout the season.

Buffalosun earns its place in seed catalogs year after year because it delivers that milestone moment: the first truly ripe tomato when you need it most. Growing as an indeterminate vine, it produces continuously rather than exhausting itself in one flush, extending your harvest deep into the season. The combination of early maturity (80 to 85 days), reliable performance, and genuine flavor makes it the kind of variety serious tomato gardeners return to season after season.
Buffalosun is grown for fresh eating, prized for the moment when the first fully ripe tomato appears on the vine. Its juice and flavor make it equally suited to slicing for salads, eating fresh off the plant, or cooking into sauces and preserves. Indeterminate varieties like this one are ideal for gardeners who want continuous harvests rather than a single glut of fruit.

Start seeds indoors 6 to 8 weeks before your last spring frost. Maintain soil temperature between 70 and 90 degrees Fahrenheit for reliable germination. Once seedlings emerge, provide bright light to prevent legginess, and harden off transplants by gradually exposing them to outdoor conditions over 7 to 10 days before planting.
Transplant outdoors once soil has warmed to at least 55 degrees Fahrenheit and all frost danger has passed. Space plants 3 inches apart in rows. Bury the stem deeply, as tomatoes will root along buried stems, creating a stronger root system.
Harvest when fruit is fully ripe and has developed its deepest color. The tomato should yield slightly to gentle pressure but not feel mushy. For best flavor, pick ripe fruit and do not refrigerate immediately. If you harvest green fruit late in the season, ripen it in a cool, dark area, making sure fruits do not touch each other to prevent soft spots and allow even ripening.
Because Buffalosun is indeterminate, it will grow indefinitely and benefit from pruning suckers (shoots that emerge between the main stem and branches). Remove these to direct energy toward fruit production and improve air circulation. Remove lower leaves as the plant matures to reduce disease pressure and allow sunlight to reach ripening fruit.
