Tomato Buffalosun F1 Seed Packet - Thompson & Morgan

An F1 hybrid seed is the first generation offspring of a cross between two distinct parent varieties. This often results in plants with improved vigour, uniformity, and disease resistance compared to open-pollinated varieties.

Yes, 'Buffalosun' F1 can be grown in large containers (at least 10 gallons) as long as they are in a sunny, sheltered location and the plant is provided with adequate support, water, and nutrients.

Begin feeding your 'Buffalosun' F1 plants with a high-potash fertiliser once the first fruits begin to set. Continue feeding regularly throughout the growing season.

Cordon type tomatoes are 'determinate' growers in terms of fruit production but grow tall and require continuous staking and pruning of side shoots to manage their vertical growth and encourage ripening along a single main stem.

Side shoots (or 'suckers') are small growths that appear in the 'V' where a leaf stem joins the main stem. Gently pinch these out with your fingers or snip them with clean secateurs as soon as you see them, typically weekly.

Pinching out the main stem once 6-7 fruit trusses have formed redirects the plant's energy into ripening the existing fruit rather than producing new flowers and leaves, leading to a better harvest before the end of the season.

While seeds can be sown outdoors from March to April, starting them indoors from February to April is recommended for a head start and better germination success, especially in the UK climate.

Ensure consistent temperature (15-20°C) and adequate moisture in the compost. Check that the compost is free-draining.

Provide more light and slightly cooler temperatures after germination. Ensure adequate spacing once transplanted into pots.

This could indicate a nutrient deficiency. Start feeding with a high-potash fertiliser once fruit begins to set. Ensure consistent watering.

Ensure the plant is in a sunny location and receiving adequate water. Hand-pollination may be necessary in very cool or windy conditions.

While resistant, severe conditions can still cause issues. Remove affected parts immediately. Ensure good air circulation around plants.
