Growing Costoluto Genovese Tomatoes in the Vegetable Garden

The Costoluto Genovese tomato, an old and improved Italian variety, offers a deliciously slightly tart flavor and is well-suited for hot weather while continuing to produce in cooler temperatures. The planting process begins in early spring, starting indoors 6 to 8 weeks before outdoor night temperatures reliably reach 50-55 F (10-13 C). Sow seeds 0.25 inch deep and 1 inch apart in a container of seed starting mix, keeping them moist and warm at 80 F (27 C). Transplant when 2 inches tall into individual 4-inch pots, burying stems up to the base of leaves. Once nights are consistently above 55 F (10 C), transplant into rich, well-prepared soil in full sun, spacing plants 3 feet apart.

To ensure optimal growth and fruit production of the Costoluto Genovese tomato, consistent maintenance practices are essential. Regularly monitor the soil moisture, avoiding overwatering, particularly once the fruits start to ripen. Mulching around the plants helps maintain even moisture levels and suppresses weeds. This indeterminate variety benefits from sturdy support, so provide strong stakes or tall wire cages at planting time to support the sprawling vines and heavy fruits. Companion planting with basil and dill enhances the flavor of the tomatoes and may help deter pests. Additionally, consider planting marigolds nearby, as they can act as natural repellents for certain insects.

Harvesting Costoluto Genovese Tomatoes

The Costoluto Genovese tomato is an indeterminate variety, meaning it continues to produce fruit throughout the growing season. Harvesting these tomatoes requires attention to their distinct characteristics. As the tomatoes ripen, they develop deep ribbing and a rich, red color. The best indicator for harvesting is when the fruits are fully red and have a slightly soft feel. To check for ripeness, gently squeeze the tomatoes – they should yield to slight pressure without being overly soft. Harvesting can be done by using pruning shears or scissors to cut the stems, leaving a small portion attached to the fruit. Indeterminate varieties like Costoluto Genovese allow for a staggered harvest, enabling growers to pick ripe tomatoes as they mature while leaving others on the vine to continue ripening. This provides an extended harvest period, allowing for a steady supply of fresh, flavorful tomatoes throughout the growing season.

About Costoluto Genovese Tomato Garden Seeds

The Costoluto Genovese tomato has a rich history dating back to the early 19th century, making it a classic Italian heirloom variety. Its deep ribbing and slightly flattened shape have made it a staple in Italian cuisine for both fresh consumption and preserving. Over the years, this tomato has gained popularity not only for its excellent flavor but also for its distinctive appearance. Chefs, in particular, appreciate its intense, deep red flesh, making it a favored choice for culinary creations. The variety is well-suited for hot weather conditions but continues to produce even when the weather turns cold, showcasing its versatility in various growing climates.

This heirloom variety was not specifically bred for a particular trait but has naturally evolved and adapted to thrive in diverse conditions. Its resilience and adaptability have contributed to its enduring popularity among gardeners and chefs alike. The Costoluto Genovese is an indeterminate vine, producing lumpy, flattish convoluted fruits weighing 6-8 oz. This tomato variety requires sturdy staking or tall wire cages to support its vigorous growth.

While the Costoluto Genovese tomato is well-suited for traditional garden plots, it may pose challenges in smaller spaces like container gardens or hanging baskets due to its indeterminate growth habit and need for substantial support. The sprawling nature of indeterminate tomatoes can make them less suitable for confined spaces. However, with proper staking and support, they can still be grown successfully in larger containers.

Tips From Our Gardeners

"To enhance the flavor and texture of Costoluto Genovese tomatoes, consider implementing a pruning technique known as "sucker pruning." Indeterminate tomatoes like the Costoluto Genovese tend to produce side shoots, or suckers, between the main stem and branches. By regularly removing these suckers, you can direct the plant's energy towards fruit production, resulting in larger, more flavorful tomatoes. Use clean and sharp garden shears to pinch off the suckers when they are small, typically around 2-4 inches in length. Focus on the lower parts of the plant, especially where the main stem meets the branches. This practice not only promotes better fruit development but also improves air circulation, reducing the risk of diseases. However, be cautious not to over-prune, as maintaining a balance is key to a healthy and productive Costoluto Genovese tomato plant."
