How to Grow Leeks

How to Grow Leeks

How to Grow Leeks Leeks are hardy winter vegetables with something of an acquired taste; loved by some, hated by others. A long growing season is required, but a good variety will stand the hardest winter weather. They are very easy to grow.

Soil requirements

Tolerant of a very wide range but it should be well drained. The lighter soils make leeks easier to lift. Possible yield Depending on the size and variety, about 10lb (4.5kg) per 10ft (3m) of row.

Time from Sowing to harvest

7-9 months.


‘Oarsman’, ‘Musselburgh’ (old, but still good), ‘Sultan’, ‘Elefant’.


Sow in February or early March in heat, prick out seedlings and later plant outside. Alternatively, sow thinly in situ during March. Another way is to sow in nursery rows in March for planting later on. All outdoor sowings are at half an inch depth.


Plant heat-raised plants outside when they are about pencil thickness. Thin out and single those sown in situ, and plant out (in May) those raised in nursery rows at the same stage. For maximum yield of medium sized leeks, plant out 6in (15cm) apart with 12in (30cm) between rows.


When planting out those sown in nursery rows, trim the roots to 1 in (2.5cm) long and plant in a 6in (15cm) deep dibber hole. Don’t fill in the holes with the dibber but pour in water to settle the plant.

Pests and diseases

Onion fly and white rot can be serious in a bad year. If white rot strikes, don’t grow leeks or onions in that place for several years.


Lift as required but cover with straw during very cold weather to stop them being frozen into the ground.
