Troubleshooting
Seedlings not germinating
Ensure seeds are within their expiry date, compost is kept consistently moist, and the temperature is maintained at the recommended level (18-21°C).
Leggy or weak seedlings
Provide more light by moving to a sunnier windowsill or using grow lights. Ensure temperatures are not excessively high.
Blossom end rot on fruit
This is often due to inconsistent watering. Ensure the soil remains evenly moist and consider calcium supplements if the problem persists.
Pests like aphids or whitefly
Inspect plants regularly. Use insecticidal soap or introduce beneficial insects for biological control. Ensure good air circulation.

Setup, Compatibility & Care
Sowing: Start seeds indoors 6-8 weeks before the last expected frost. Sow thinly in pots or trays filled with seed compost, covering lightly with compost. Maintain a temperature of 18-21°C (65-70°F).
Potting On: Once seedlings are large enough to handle, pot them into individual 9cm (3.5 inch) pots. Grow on in good light and gradually acclimatize to outdoor conditions before planting out.
Planting Out: Plant into grow bags, large pots (at least 30cm/12 inches diameter), or directly into the greenhouse border. Space plants about 45cm (18 inches) apart. Provide sturdy support such as canes or stakes as this is a cordon variety.
Watering: Water consistently, especially during dry periods. Aim to keep the soil moist but not waterlogged.
Feeding: Once fruits begin to set, feed regularly with a high-potash liquid fertilizer every 10-14 days.
Pruning: While tips don't strictly need pinching, remove side shoots (laterals) that grow between the main stem and the branches to encourage larger fruits and better air circulation. Continue to train the main stem upwards.
Compatibility: Suitable for greenhouse cultivation, pots, patios, and can tolerate lower light levels. It thrives in well-drained, fertile soil.
