FAQs
When should I sow Unwins Winter Giant 2 leek seeds?
Sow seeds from January to April for a winter harvest.
When can I expect to harvest these leeks?
Harvest is typically from December through April.
How do I ensure long white stems?
As the plants grow, gradually draw soil up around the base (hilling) to blanch the stems. Keep them well-watered and fed.
Are these leeks suitable for very cold climates?
Yes, these leeks are specifically bred to be winter hardy and resistant to extreme cold temperatures.
What is the spacing for planting out leeks?
Plant them 20 cm apart in rows that are 30 cm apart.
Can I grow these leeks in containers?
While they prefer garden beds for optimal hilling, with deep containers and careful soil management, container growing might be possible, though challenging for achieving long white stems.
What does 'bolt resistance' mean for leeks?
Bolt resistance means the plant is less likely to prematurely send up a flower stalk, which can affect the texture and flavor of the leek's edible stem.
Troubleshooting
Seeds not germinating
Ensure seed trays are kept consistently moist and warm. Check seed depth; planting too deep can hinder germination.
Leeks are short and not developing white stems
Ensure you are 'hilling' the plants by drawing soil up around the base as they grow. Consistent watering is also crucial.
Plants bolting prematurely
While this variety is bolt-resistant, stress from inconsistent watering or extreme temperature fluctuations can contribute. Ensure steady moisture and a suitable planting time.
Poor plant growth
Ensure plants are receiving adequate water and regular feeding. Check for pests or diseases and address accordingly.
