Troubleshooting
Seeds fail to germinate
Ensure seeds are sown at the correct depth (2cm) and are kept consistently moist and warm (around 18-21°C). Check soil temperature if sowing directly outdoors.
Plants are growing but not producing fruit
While 'Sure Thing' F1 is parthenocarpic (sets fruit without pollination), adequate sunlight, water, and nutrients are crucial for fruit development. Ensure the plant is not stressed by drought or nutrient deficiency.
Courgettes are small or misshapen
This can be due to insufficient water, nutrients, or sunlight. Increase watering frequency, feed with a balanced liquid fertilizer, and ensure the plant receives at least 6 hours of sunlight daily.
Yellowing leaves
This may indicate a nutrient deficiency, overwatering, or poor drainage. Check soil moisture and consider a balanced liquid feed. Ensure the pot has adequate drainage holes.

Setup, Compatibility & Care
Sowing Seeds: Sow seeds indoors in pots or modules from April to May, or directly outdoors from May to June when the risk of frost has passed. Plant seeds about 2cm deep. For indoor sowing, use a good quality seed compost and provide a warm environment.
Transplanting: Harden off indoor-sown seedlings before transplanting them outdoors in June. Choose a sunny, sheltered spot with well-drained, fertile soil. If growing in pots, use a large container (at least 30cm in diameter) filled with good quality potting compost.
Care: Water regularly, especially during dry spells, and feed with a balanced liquid fertilizer every few weeks once the fruits begin to form. Keep plants well-watered to prevent bitter-tasting courgettes and ensure continuous cropping. Mulching around the base can help retain moisture.
Compatibility: This variety is highly compatible with container gardening, raised beds, and small plots due to its compact growth habit.
