This tomato excels as a fresh slicer, where its distinctive appearance and complex flavor shine on the plate.

Start seeds indoors 6 to 8 weeks before your last frost date. Sow seeds in seed-starting mix at a depth of approximately 1/4 inch, keeping soil temperature between 68 and 82 degrees Fahrenheit for consistent germination. Provide bright light once seedlings emerge to prevent legginess.
Harden off seedlings over 7 to 10 days by gradually exposing them to outdoor conditions. Transplant outdoors after the last frost date when soil temperature has reached at least 60 degrees Fahrenheit and nighttime temperatures consistently stay above 50 degrees. Space plants 24 inches apart in rows.
Harvest tomatoes when they reach full color with honey-brown skin and slight give when gently squeezed. Pick fruit at the mature stage rather than waiting for absolute peak softness, as this variety is prone to splitting in late season. Harvest frequently during mid-season peak production to encourage continued flowering. Fruit ready for harvest will detach easily from the vine when twisted gently.
As a determinate variety, Thorburn's Terra-cotta grows to a compact, bushy form and requires minimal pruning compared to indeterminate types. Remove any diseased or damaged leaves as they appear, and thin out lower foliage once fruit sets to improve air circulation and reduce disease pressure. Light pruning of suckers can help direct energy toward fruit production, but avoid excessive pruning that would remove flowering stems.
