description

Organic Black Prince Tomato (Solanum lycopersicum) is an heirloom, indeterminate annual variety valued for its dark reddish-brown to purplish-brown fruits, which are both decorative and flavorful. The vigorous plant reaches approximately 1.8 to 2.1 m (6 to 7 ft) in height and produces generously throughout summer when properly staked. Its juicy, dense, aromatic tomatoes offer a rich, complex flavor that is slightly sweet and balanced by gentle acidity, typical of dark tomato varieties. Harvested about 70 days after transplanting, this variety brings a distinctive touch to fresh salads, sandwiches, artisan sauces, and tasting platters.

Organic Black Prince Tomato should be sown indoors from March to April, about 6 to 8 weeks before the last expected frost in Canada. Seeds germinate well between 21 and 27°C (70 to 81°F), in a light, fertile, well-drained growing mix. Transplant young seedlings once they have several true leaves, then gradually harden them off before planting outdoors or in large containers. Set plants in full sun, in deep, organic-rich, slightly acidic to neutral, well-drained soil. Deep, regular, and even watering, combined with mulch, supports fruit development and helps prevent cracking.

In the garden, Organic Black Prince Tomato is ideal for edible vegetable gardens, heirloom collections, and large 45 to 60 cm (18 to 24 in) diameter containers on sunny patios. It grows well alongside basil, chives, and parsley, while avoiding proximity to potatoes, fennel, and kohlrabi whenever possible. Its yellow flowers attract bees and other pollinating insects, supporting vegetable garden biodiversity and good fruit production. Harvest fruits once they show their characteristic dark coloration and feel slightly soft under your fingers.

method

Start Solanum lycopersicum seeds indoors from March to April, approximately 6 to 8 weeks before the last expected frost in Canada. Maintain temperatures between 21 and 27°C (70 to 81°F) for rapid, uniform germination and vigorous seedlings. Transplant seedlings into individual containers after several true leaves develop to encourage strong root systems. Harden plants off for 7 to 10 days before transplanting outdoors into fertile, well-drained soil in full sun. Install a sturdy stake or cage at planting, as this indeterminate Solanum lycopersicum tomato produces vigorous vines and heavy fruits. Water deeply and consistently, apply organic mulch to conserve moisture, and fertilize regularly throughout the season to encourage continuous flowering and abundant harvests.
