FAQs

Can these tomatoes be grown outdoors?

While the collection is primarily selected for greenhouse growing, the 'Gardener's Delight' variety is noted to perform well outdoors if conditions are suitable and space allows.

What is the expected height of the plants?

The plants can reach approximately 1800 mm (around 6 feet) in height, so ensure you have adequate vertical space and support.

When should I sow the seeds?

Sow seeds indoors between January and April. Transplant outdoors or into the greenhouse after the last frost.

What type of compost should I use?

It is recommended to use a peat-free seed compost for sowing.

How often should I water the tomato plants?

Water consistently, especially during dry spells, aiming to keep the soil evenly moist. Avoid letting the plants dry out completely.

What does 'F1 hybrid' mean?

F1 hybrids are the first generation offspring of two distinct parent lines. They often exhibit 'hybrid vigor,' meaning they can be more robust, uniform, and productive than their parent varieties.

When can I expect to harvest the tomatoes?

Harvesting typically begins in July and continues through September, depending on sowing time and growing conditions.

Troubleshooting

Seeds fail to germinate

Ensure seeds are sown at the correct depth, the compost is kept consistently moist but not waterlogged, and the temperature is warm enough (ideally 18-21°C).

Seedlings are leggy and weak

Provide more light. Move seedlings closer to a light source, such as a sunny windowsill or grow lights. Ensure temperatures are not excessively high.

Plants are not fruiting

Ensure adequate sunlight, consistent watering, and appropriate feeding. Pollination issues can occur in very still environments; gentle shaking of plants or good ventilation can help.

Blossom end rot on fruit

This is often caused by inconsistent watering. Ensure the soil remains evenly moist and consider calcium supplements if the problem persists.

Setup, Compatibility & Care

Sowing: Sow seeds indoors between January and April using a peat-free seed compost. Ensure a warm environment for germination.

Transplanting: After the last frost has passed, carefully transplant seedlings into their final growing positions. Ensure adequate spacing for mature plants.

Support: As plants can reach up to 1800 mm (approximately 6 feet), provide sturdy support such as stakes, cages, or trellises from an early stage.

Watering: Water consistently, especially during dry periods, to prevent fruit splitting and blossom end rot. Avoid wetting the foliage to minimize disease risk.

Feeding: Tomatoes are hungry plants. Feed regularly with a high-potash fertilizer once the first fruits begin to set.

Greenhouse Environment: Maintain good ventilation in the greenhouse to prevent fungal diseases and ensure pollination. Remove side shoots on cordon varieties as they appear.
