Growing St. Pierre Tomatoes in the Vegetable Garden

To plant St. Pierre tomatoes, begin indoors 6-8 weeks before the last frost date. Sow the seeds 0.25 inches deep in seed-starting trays filled with potting mix. Keep the trays in a warm, sunny location and maintain consistent moisture until germination, which typically occurs in 7-14 days. Once the seedlings have developed their first true leaves, transplant them into individual pots filled with rich, well-draining soil. Continue to grow the seedlings indoors, providing ample sunlight or artificial light and keeping the soil consistently moist. About 2 weeks before the last frost date, begin hardening off the seedlings by gradually exposing them to outdoor conditions. This process helps the plants adjust to the change in environment and reduces transplant shock. After the danger of frost has passed, usually around mid-May, transplant the St. Pierre tomato seedlings into their final outdoor location. When planting, amend the soil with organic compost and ensure proper spacing to allow for healthy growth.

Keep the soil consistently moist but not waterlogged, because tomatoes are susceptible to diseases like blossom end rot if overwatered. Mulching around the base of the plants helps retain moisture and suppress weeds. Make sure to provide support for the indeterminate vines with stakes or cages to prevent sprawling and promote air circulation. This can reduce the risk of fungal diseases. Companion planting with herbs like basil, parsley, or chives can help deter pests and bring in beneficial insects to the garden. Pruning the lower leaves of the plants can improve air circulation and reduce the likelihood of fungal infections. Make sure to keep an eye out for pests and diseases and take action, if necessary, to help maintain the health and productivity of the St. Pierre tomato plants throughout the growing season!

Harvesting St. Pierre Tomatoes

Because they’re an indeterminate variety, St. Pierre tomatoes produce fruit continuously throughout the growing season. Harvesting can start when the tomatoes reach their mature color, which is a vibrant red, and when they have a firm texture. The fruit should be fully developed but not overly soft. One way to check the ripeness is by gently squeezing the tomato; it should yield slightly to pressure without being mushy. Using clean, sharp garden shears or scissors, cut the tomatoes from the vine, leaving a short stem attached. Avoid pulling or twisting the fruit to prevent damage to the plant. Harvesting should be done regularly to encourage further fruit production and prevent the plant from becoming overcrowded. St. Pierre tomatoes are versatile and can be used fresh in salads, sandwiches, or cooked in different dishes.

About St. Pierre Tomato Garden Seeds

St. Pierre tomatoes trace their roots back to France, where they have been grown for generations as a loved heirloom variety. Although the exact origins remain somewhat obscure, their popularity in French cuisine and gardens is well-documented. Known for their robust flavor, juicy texture, and versatility in cooking, St. Pierre tomatoes have earned a reputation for deliciousness among both gardeners and chefs.

This variety of tomato was not specifically bred for a particular trait, but it is valued for its growth and adaptability. Because of its indeterminate growth habit, St. Pierre is a good fit for a range of growing climates, because it thrives in both greenhouse and outdoor settings. Its resilience against diseases and pests, along with its ability to produce fruit throughout the season, make it a great choice for gardeners who want a steady supply of tasty tomatoes.

Along with its culinary benefits, St. Pierre tomatoes can add to the beauty of your garden. The plants can reach heights of up to 2 meters and are covered in clusters of medium-sized, red fruits that get ripe gradually over the season. The tomatoes have a mild, sweet flavor with a hint of acidity, making them perfect for slicing fresh into salads or sandwiches, as well as for cooking in soups, sauces, and other dishes.

While St. Pierre tomatoes are normally grown in traditional garden beds or raised beds, they can also grow well in container gardens, if they are given enough space and support. Their indeterminate growth may require staking or trellising to support the weight of the vines and fruit. While hanging baskets may not be the best choice for this variety due to their size and growth, some gardeners can experiment with alternative vertical gardening methods to try to grow St. Pierre tomatoes in smaller spaces.

Tips From Our Gardeners

"Try the technique of foliar feeding with a compost tea! Dilute homemade compost tea or organic liquid fertilizer and spray it directly onto the foliage of your tomato plants once about every two weeks during the growing season. Foliar feeding gives your plants a quick nutrient boost and encourages strong, healthy growth by delivering important nutrients directly to the leaves for quick absorption. This method can supplement soil fertilization and promote vigorous fruit production."
