FAQs

What does 'F1 vigour' mean?

F1 vigour refers to the traits of a hybrid plant created by crossing two distinct parent varieties. These hybrids often exhibit enhanced characteristics like faster germination, stronger growth, disease resistance, and higher yields compared to non-hybrid varieties.

Is this variety suitable for outdoor growing?

While ideal for greenhouses, Sweet Million F1 can be grown outdoors in pots or garden beds in warmer climates with good sun exposure. Ensure protection from late frosts and provide support.

How many seeds are in a pack?

Each pack contains approximately 15 seeds.

When is the best time to sow these seeds?

Sow indoors between January and April for the best results. Transplant outdoors or into larger containers after all risk of frost has passed.

Do I need to feed these tomatoes?

Yes, feeding with a purpose-formulated tomato feed at flowering time is recommended to boost fruit development and ensure the best flavour and yield.

What is a cordon variety?

A cordon variety, like Sweet Million F1, grows upwards with a single main stem. It requires support such as canes or strings to grow vertically and needs regular pinching out of side shoots to maintain its growth habit.

How tall do these plants get?

Plants typically reach about 1800 mm (approximately 6 feet) in height and require adequate support.

Troubleshooting

Seeds not germinating

Ensure seeds are sown at the correct depth (1 cm), kept consistently moist, and in a warm, bright location. Check the age of the seed packet; older seeds may have reduced viability.

Seedlings are leggy or weak

Provide more light and ensure adequate but not excessive moisture. Avoid overcrowding seedlings after germination. Rotate trays for even light exposure.

No fruit set or poor fruit development

Ensure plants receive adequate sunlight and consistent watering. Apply a tomato-specific feed at the flowering stage to provide essential nutrients for fruit development.

Plants are leaning or falling over

This is a cordon variety and requires staking or tying to a support system (canes or strings) as soon as possible after transplanting to prevent damage.

Setup, Compatibility & Care

After Germination:

  1. Remove covers once seedlings appear.
  2. Keep compost consistently moist.
  3. Rotate trays regularly for even growth.
  4. When seedlings are large enough, transfer them into individual pots.

Transplanting (After Risk of Frost Has Passed):

  1. Move plants to larger pots, growbags, or directly into the soil.
