FAQs
What does 'Carentan 3' mean?
'Carentan 3' refers to a specific cultivar or variety of leek, known for its particular characteristics like hardiness and stem shape, developed or popularized by breeders.
How many seeds are in a packet?
Each packet contains an average of 400 seeds.
Can I sow these seeds outside of the recommended months?
While the recommended months provide optimal conditions, you may try sowing slightly outside these times, but germination and growth success might be reduced due to temperature or light variations.
What is the benefit of 'organically grown' seeds?
Organically grown seeds are produced without synthetic pesticides or fertilizers, contributing to healthier soil and a more sustainable growing environment. They are approved by certified organic bodies like OF&G.
How do I ensure the leeks have thick white stems?
To achieve thick white stems, it's important to sow seeds deeply and then 'earth up' the plants as they grow by drawing soil around the lower part of the stem.
What is the harvesting period for these leeks?
These leeks are typically harvested from October through to February, offering a long season for homegrown produce.
Is the planting marker reusable?
The included planting marker is weather-resistant, designed for durability in outdoor conditions, and can be reused for multiple seasons.
Troubleshooting
Seeds not germinating
Ensure seeds are within their viable period, sown at the correct depth, and kept consistently moist and warm (15-20°C).
Leeks are thin or small
Provide adequate spacing, consistent watering, and ensure soil is fertile. Earthing up the stems properly also encourages thicker growth.
Pests affecting seedlings
Monitor for common garden pests. Use organic pest control methods if necessary, and ensure good air circulation.
Yellowing leaves
This can indicate a lack of nutrients or overwatering. Ensure soil is well-drained and consider a balanced organic feed if growth is slow.

Setup, Compatibility & Care
Sowing: For indoor sowing, start seeds in pots or trays from January to February in a propagator or warm windowsill. For outdoor sowing, prepare a well-drained seedbed or sow directly into the final growing position from March to April. Aim for a soil temperature of 15-20°C for optimal germination.
Planting Out: Once seedlings are large enough to handle (approximately 15cm tall), transplant them into their final growing positions, planting them deeply to encourage a long white stem. Space plants about 15cm apart in rows 30-45cm apart.
Care: Keep the soil consistently moist, especially during dry periods. Earth up the stems as the plants grow by drawing soil around them to blanch them and encourage the development of the white stem.
Harvesting: Leeks can be harvested from October through to February, depending on your sowing time. Gently loosen the soil around the base of the leek and pull upwards. Ensure you harvest before the ground freezes solid if possible.
Compatibility: These seeds are suitable for most garden soils but thrive in well-drained, fertile ground. They are compatible with organic gardening practices.
