Costoluto Genovese Pole Tomato is an Italian heirloom that brings authentic Mediterranean flavor to the home garden. This indeterminate pole variety reaches maturity in 80 to 90 days and demands full sun and consistent moderate watering to produce its best fruit. Half-hardy in nature, it thrives in warm soil (ideally 70 to 90°F for germination) and prefers slightly acidic conditions between pH 6.0 and 6.8. Its tall growth habit makes it well-suited to trellising, where it will continue producing throughout the season.

Named for Genoa, Italy, this pole tomato carries the culinary traditions of the Liguria region straight into your garden. The indeterminate growth habit means continuous production rather than a single heavy flush, rewarding gardeners who provide sturdy support and consistent care. Sow seeds indoors 4 to 6 weeks before your last frost date, transplanting outdoors once air temperatures reach at least 45°F and soil warms to a minimum of 60°F.
As a pole tomato suited to Italian cuisine, Costoluto Genovese serves fresh in salads, sauces, and traditional preparations where quality flavor takes center stage. The indeterminate growth habit and extended season make it reliable for preserving and sauce-making throughout summer and early fall.

Start seeds indoors 4 to 6 weeks before your planned transplant date. Sow seeds at a depth of 1/4 inch in seed starting mix and maintain soil temperature between 70 and 90°F for best germination. Keep soil consistently moist but not waterlogged until seedlings emerge.
Transplant outdoors when air temperature is consistently 45°F or warmer, typically 1 to 2 weeks after your average last frost date. Soil temperature should be at least 60°F. Space plants 36 inches apart in rows 36 inches apart. Harden off seedlings gradually over 7 to 10 days before moving them to their final location to acclimate them to outdoor conditions.
Direct sowing is not recommended for mild climates only and should only occur 1 to 2 weeks after average last frost date when soil temperature is at least 60°F.
Harvest tomatoes when they reach full color and yield slightly to gentle pressure. Fruits can be picked at the mature green stage and ripened indoors if frost threatens, or left on the vine for peak flavor development. Because this is an indeterminate variety, harvesting will continue throughout the season as new flower clusters mature.
As an indeterminate variety, this tomato benefits from selective pruning and suckering to manage vigor and improve fruit production. Remove lower foliage once plants are established to enhance air circulation and reduce disease pressure. Prune suckers (shoots that emerge between the main stem and branches) to direct energy into fruit-bearing branches and maintain manageable vine size on your trellis.
