Tomato Furnace F1 Plants

The F1 'Fournaise' Tomato is one of the first creations of INRA in the 1950s in terms of tomato cross-breeding. Its value is being very early. You can start harvesting it two months after transplanting, which is 2 weeks to a month earlier than most other varieties. Fournaise produces fruits that weigh on average 120 to 150g, bright red and shiny. Their excellent taste allows them to be used in various culinary preparations, from salads to stuffed dishes. The plug plants are planted from May to June after the last frost when the plants have reached about 15 cm. Harvest from late June or July until October.

NB: This variety is labeled F1 for "F1 hybrid" because it is a variety resulting from the cross-breeding of carefully selected parents to combine their qualities. This results in a variety that can be particularly tasty and/or early while also being resistant to certain diseases. Sometimes criticised or wrongly associated with GMOs, F1 hybrid plants are interesting both for their uniformity and their resistance, but unfortunately, their qualities do not pass on to subsequent generations: we therefore advise against saving the seeds for later sowing.

The Tomato originated in South America and Central America. Several varieties were already cultivated by the Incas long before the arrival of the Conquistadors. The term Tomate comes from the Inca Tomatl and refers to both the plant and the fruit it bears. It is one of the many foods that was taken from the New World, along with beans, corn, squash, potatoes, and chilli peppers. The Tomato took considerably longer to reach our taste buds. The reason for this is that it was long cultivated for its aesthetic and medicinal qualities, but it was considered toxic due to its resemblance to the fruit of the Mandrake, another member of the Solanaceae family. It only became a regular part of our diet from the beginning of the 20th century.

The Tomato is a perennial herbaceous plant in tropical climates, but it is grown as an annual in our latitudes. It becomes lignified over time and produces small insignificant yellow flowers grouped in cymes that will turn into fruits. Tomatoes can be grown in open ground but can also be planted in containers on a balcony, especially varieties with small growth.

It is a fruity vegetable that has many nutritional benefits. Low in calories like most vegetables, rich in water, it also contains a very interesting molecule: lycopene, a powerful antioxidant. It is also rich in vitamin C, provitamin A, and trace elements.

In terms of cooking, Tomatoes can be consumed raw or cooked in multiple ways: in salads or as appetisers, grilled, stuffed, marinated, preserved, or in sauces. They come in all colours, shapes, and sizes. Take advantage of this and cultivate several varieties in your vegetable garden to vary your weekly menu!

Harvesting: Harvest times vary depending on the variety’s maturity: early varieties are harvested from 55 to 70 days after planting, mid-season varieties from 70 to 85 days, and late varieties beyond 85 days. Harvesting is done when the Tomato takes on its final colour and when its texture, while remaining firm, shows a slight softening. For better preservation, be sure to pick the fruit with its stem. Be careful, immature fruits, stems, and leaves contain solanine and should not be consumed.

Storage: The optimal storage temperature for tomatoes is between 10 and 15°C (50 and 59°F). Refrigeration is possible but alters the taste of the fruits. For longer storage, Tomatoes can be preserved, dried, frozen, canned, or cooked into jam. To preserve them, cut your tomatoes in half and collect the juice. Place your halved tomatoes face up on a baking sheet. Season with salt, pepper, and sugar, then bake at a very low temperature for at least an hour. Remove your tomatoes, store them in a glass jar, and cover with olive oil.

Gardener's tip: To limit watering, we recommend mulching the soil with thin, successive layers of grass clippings, mixed with dead leaves if possible. This protection, which keeps the soil moist, also limits weed growth.
