What Is a Stupice Tomato?
Stupice is a Czech heirloom prized for early, heavy harvests in cool weather. The plant has potato-leaf foliage and keeps setting small to medium fruit even when nights are chilly. That makes it a top choice for short seasons, high altitudes, and northern gardens. Because it is open-pollinated, you can save seeds and grow it again next year.
Stupice Flavor and Best Uses
Stupice has a sweet, tangy, well-balanced flavor that is surprisingly strong for such an early tomato. The fruit is small to medium and easy to use.
It is an all-purpose tomato. Slice it for sandwiches, halve it for salads, or snack on it fresh. Its early fruit is often the first ripe tomato of the season.
How to Grow Stupice Tomatoes
Stupice is easy to grow and very forgiving. Follow these basics.
- Sun: give plants 6 to 8 hours of direct sun.
- Spacing: set plants 24 to 36 inches apart.
- Support: use a tall stake or cage for the climbing vines.
- Water: water deeply and evenly to keep fruit smooth.
- Feeding: feed with a balanced tomato fertilizer once fruit sets.
You can set Stupice out a bit earlier than other tomatoes, since it tolerates cool weather.
Common Problems and Disease Resistance
Stupice is tough and cold tolerant, but it has limited disease resistance, so watch for a few issues.
- Cracking: uneven water after dry spells can split the fruit.
- Blossom end rot: a dark spot on the bottom from low calcium and uneven water.
- Tall vines: the productive plants need regular tying.
Stupice vs Early Girl
Both are early tomatoes, so gardeners compare them. Stupice is a cold-tolerant heirloom with smaller fruit and the bonus that you can save its seeds. Early Girl is a hybrid with larger fruit and good disease resistance. Gardeners in cool climates often pick Stupice for its early, reliable crop.
When to Harvest Stupice Tomatoes
Pick Stupice when the fruit is fully red and gives slightly to a gentle squeeze. The plant produces in waves, starting earlier than most, so check it every couple of days. Harvest before heavy rain to avoid cracks, and enjoy the season first ripe tomatoes.
Growing Stupice in Containers
Stupice grows well in a container of at least 10 gallons with a tall cage. Its early, steady harvest makes a single patio pot rewarding. Keep the soil evenly moist, since pots dry out faster than garden beds.
Companion Plants for Stupice
Stupice pairs well with basil, which may improve flavor and repel pests. Marigolds deter nematodes, and lettuce makes good use of the shade under the plants. Keep tomatoes away from potatoes, which share diseases. Good companions support an early, clean harvest.
Stupice Nutrition
Stupice is low in calories and rich in nutrients. A tomato gives you vitamin C, vitamin A, potassium, and lycopene, the antioxidant linked to heart health. Its early fruit is a fresh, healthy start to tomato season.
Where to Buy Stupice Seeds and Plants
Stupice seeds are sold at most seed companies in spring, and cool-climate nurseries often carry plants. Because it is open-pollinated, one packet can supply your garden for years if you save seeds from your best fruit.
Care Notes
Plant in rich, well-drained soil and mulch around the base to keep that soil evenly moist. Set out sturdy transplants only after the last frost has passed. Prune lower leaves and crowded stems to improve airflow.
