FAQs
How large do the 'Supersteak' tomatoes get?
Individual tomatoes can weigh up to 500g each, making them exceptionally large beefsteak varieties.
Is this a bush or a climbing tomato variety?
This is a cordon (indeterminate) variety, meaning it grows tall on a single main stem and requires support. It is not a bush variety.
Do I need to prune 'Supersteak' tomato plants?
Yes, for optimal fruit production and size, it is essential to remove side shoots regularly and consider stopping the main stem when it reaches its desired height.
Can I grow these tomatoes in containers?
Yes, they can be grown in large containers (at least 30cm in diameter) with good drainage and consistent watering.
What does the RHS Award of Garden Merit signify?
This award indicates that the variety has been judged to have outstanding performance and reliability in garden trials.
How many seeds are in a pack?
Each pack contains approximately 10 seeds.
When is the best time to sow these seeds?
Sow seeds indoors 6-8 weeks before the last expected frost date, aiming for a germination temperature of 18-21°C.
Troubleshooting
Seeds not germinating
Ensure seeds are fresh, sown at the correct temperature (18-21°C), and kept consistently moist but not waterlogged. Use a good quality seed compost.
Leggy seedlings
Seedlings may be getting insufficient light or are sown too deeply. Ensure they are in a bright location and sown shallowly. Provide adequate spacing as they grow.
Plants not producing fruit
Check for adequate sunlight, pollination (ensure access for pollinators if outdoors), and proper feeding. Extreme temperatures or lack of water can also inhibit fruiting.
Blossom end rot on tomatoes
This is often caused by inconsistent watering. Ensure plants are watered regularly and deeply, especially during dry periods. Calcium deficiency can also be a factor.
Poor fruit size
Ensure plants are adequately pruned (side shoots removed) and fed with a suitable fertilizer. Consistent watering and sufficient sunlight are also crucial.

Setup, Compatibility & Care
Sowing: Start seeds indoors 6-8 weeks before the last expected frost date. Sow seeds thinly on the surface of moist seed compost and cover with a fine layer of compost. Keep at a temperature of 18-21°C.
Transplanting: Harden off seedlings gradually before transplanting them into their final growing positions (greenhouse or outdoors) once all danger of frost has passed. Space plants about 60-75cm apart.
Support: As a cordon variety, these plants require sturdy support. Install stakes or cages at planting time to avoid root disturbance later.
Pruning: Remove side shoots that grow from the leaf axils regularly. This concentrates the plant's energy into developing large fruits on the main stem. Stop the main stem when about 4-5 trusses have formed, or when the plant reaches the top of its support.
Watering & Feeding: Water consistently, especially during dry spells, to prevent blossom end rot and cracking. Feed regularly with a high-potash fertilizer once fruits begin to form.
Compatibility: Suitable for most soil types, but perform best in well-drained, fertile soil. Can be grown in containers, provided they are large enough (at least 30cm diameter).
