How to grow leeks
Sow leek seed 1cm deep in a seedbed.
When seedlings are 20cm tall, transplant them by first trimming the leaf-tips and roots, then drop into holes 15cm deep (use a dibber if you have one) and 15-30cm apart.
Don't fill the holes with soil but water well to help the plants settle.
Lift plants as required during the winter. You can start harvesting them as baby leeks to prolong the harvest period.
Loosen with a fork before lifting.
Tips on growing leeks
Carefully remove weeds from around the leeks and pull soil around the stems when the plants are large to exclude light ('blanch'), keeping them white.
