Characteristics of the Violet Jasper black violet tomato
The Violet Jasper black violet tomato (purple tomato), Solanum lycopersicum, is a highly productive mid-season variety from China. Named "Violette Jasper" or "Tzi Bi U", it produces smooth, round fruits weighing 30 to 90 g, purplish-red with green marbling and delicious red flesh.
When to sow purple tomatoes?
Violet Jasper black tomato seedlings can be sown from the end of February under glass until April, in pots or in trays, under a very bright shelter and at a temperature between 16 and 20°C.
- Bury seeds 5-7 mm deep in potting soil;
- Water the seedlings, but do not over-water;
- Place tomatoes indoors under a light source or in a nursery;
- Transplant into a pot when the tomato reaches the stage of 2 to 4 true leaves. Bury the stem up to the two cotyledons to encourage root development and keep the plants out of the cold;
- For 4 to 7 days before planting, take the tomato plants outside during the day to acclimatize them to outdoor conditions;
- As soon as the tomatoes are strong, transplant the whole clod into the vegetable garden, in full sun, after the last frosts. Greenhouse plants can be transplanted when indoor temperatures no longer fall below 10°C;
- Keep a minimum distance of 50 cm between plants, burying the stem up to the first leaves;
- Water tomatoes abundantly when planting in the vegetable garden.
In the vegetable garden, purple tomatoes enjoy the company of cabbage, lettuce, cucumber, tagetes and basil, which repel pests and improve yields. However, we advise against combining potatoes and eggplants with tomatoes.
How to care for purple tomatoes in the garden?
This variety of tomato has an indeterminate growth habit. The stem continues to lengthen, forming numerous lateral branches, all of which produce flowers. Pruning is not recommended. Pruning can cause open wounds to the tomatoes and encourage the spread of disease. Install sturdy stakes or cages to support these bulky plants.
To avoid fungal diseases such as mildew or apical necrosis, we recommend regular, but not excessive, watering of tomatoes, without wetting foliage or flowers. You can also mulch the soil to conserve moisture, and use organic preventive treatments such as nettle purin and comfrey.
