Purple Ukrainian Vine Large Tomato - Care Sheet

Overview

Purple Ukrainian Vine Large Tomato is best matched to the heirloom tomato ‘Purple Ukrainian’, also recorded as ‘Ukrainian Purple’ or ‘Purple Russian’. These names describe an indeterminate tomato with elongated, plum-shaped fruit and rich, dark red to purplish-black colouring. The additional words “Vine Large” appear to be a shop description rather than a verified separate cultivar name; check your plant label for confirmation.

Its meaty fruit suits salads, sauces and preserving. As a vining tomato, it keeps growing and cropping while conditions remain favourable. Give it sunshine, sturdy support and consistent moisture. We rate care as intermediate because regular watering, feeding and training make a noticeable difference.

Quick Facts

Light

Choose your sunniest sheltered spot. Six hours of direct sunlight is the minimum; eight to ten generally supports better growth and cropping. A greenhouse helps in cool climates, but needs ventilation. Give indoor seedlings strong overhead light to prevent stretched, weak stems. Gradually acclimatise young plants to outdoor sunshine before planting out.

Water

Keep the root zone evenly moist without leaving it waterlogged. For garden beds, around 25 mm / 1 in of rain or irrigation weekly is a starting point, with more needed during hot, dry weather. Water deeply at soil level rather than splashing foliage.

Check containers daily in summer and water according to compost moisture; they may need daily attention in heat. Allow excess water to drain freely. Mulch beds to slow drying, and avoid cycles of severe drought followed by heavy soaking.

Humidity

Moderate humidity suits tomatoes; roughly 40–70% is a useful flowering guideline rather than a strict outdoor requirement. Very dry air or persistently high humidity can interfere with pollen transfer. Open greenhouse vents and doors when conditions allow, space plants generously, and avoid routine leaf misting. Air movement and dry foliage help limit disease.

Temperature

Aim for daytime warmth around 21–29°C / 70–85°F. Wait until frost risk has passed and soil has warmed before planting outdoors. Cold nights below approximately 13°C / 55°F can disrupt fruit set, while prolonged days above 32°C / 90°F and warm nights can cause flower drop. Ventilate greenhouses and use temporary light shading during extreme heat.

Soil & Potting

Use fertile soil enriched with well-rotted compost, with good drainage and enough organic matter to retain moisture. A pH around 6.0–7.0 is a practical target. For containers, choose fresh, peat-free potting compost and a pot with drainage holes, preferably toward the larger end of 30–45 cm / 12–18 in diameter.

Install a tall stake, strong cage or trellis at planting. Ungrafted tomatoes can be planted deeper to encourage roots along the buried stem; keep a grafted plant’s graft union above the soil.

Feeding

Prepare beds according to a soil test where possible. Once the first fruit sets, feed container plants with a tomato fertilizer at the label’s dilution and frequency. Garden plants may need less supplementary feeding if soil is already fertile. Too much nitrogen encourages leafy growth at the expense of fruit. Avoid adding Epsom salts unless testing confirms a magnesium deficiency.

Repotting

Move seedlings into individual pots once they have true leaves, then pot on when roots fill the available space. There is no fixed annual repotting schedule: tomatoes are usually grown as seasonal crops. Transfer established young plants into their final container or bed after hardening off. Avoid repeatedly disturbing the roots of a heavily fruiting plant.

Propagation

Sow seeds indoors about six to eight weeks before your intended planting date. Use clean seed compost, sow approximately 6 mm / ¼ in deep, and keep moist. Warm conditions around 21–27°C / 70–80°F encourage germination. Provide bright light promptly after emergence.

As an heirloom, this tomato is suitable for seed saving. Choose healthy, fully ripe fruit, and remember that cross-pollination with other tomato varieties can affect the next generation.

Common Problems

Blossom-end rot

A dark, sunken patch at the fruit’s base often reflects disrupted calcium uptake caused by uneven moisture. Stabilise watering and mulch the soil. Test before adding calcium; automatic supplementation may not help.

Cracked fruit

Although this variety is often described as crack-resistant, sudden moisture changes can still split fruit. Maintain steady watering and harvest ripening tomatoes before heavy rain when practical.

Flowers dropping without fruit

Temperature extremes and unsuitable humidity can prevent pollination. Ventilate, keep roots moist and gently tap greenhouse flower trusses to release pollen. Fruit set often improves when weather moderates.

Spotted or browning leaves

Leaf spots may indicate fungal or bacterial disease. Keep foliage dry, improve airflow and remove affected lower leaves. Seek identification if damage spreads rapidly; different diseases require different responses.

Toxicity & Pet Safety

This plant is not pet-safe. Tomato plants belong to the nightshade family, Solanaceae. Their foliage and stems contain toxic compounds; keep pets away from plants, unripe fruit and pruning waste. The tomato group is toxic to cats, dogs and horses, although ripe fruit is classed as non-toxic. Contact a veterinarian if your pet eats plant material or develops drooling, vomiting, weakness or unusual behaviour.

Seasonal Care

In spring, harden plants off gradually and wait for frost-free conditions. During summer, tie stems loosely to supports and remove side shoots if training as a single cordon. Retain enough foliage to shade fruit. Before autumn frost, bring mature, sound fruit indoors to finish ripening. Clear spent plants and rotate tomato beds between seasons.

Quick Tips

• Confirm the cultivar name on your plant label.
• Install strong supports before growth becomes heavy.
• Check container moisture daily in warm weather.
• Water the roots and keep leaves dry.
• Feed according to the label once fruit sets.
• Keep plants and pruning waste away from pets.
