You can sow leek seeds directly into well prepared soil and thin them later. However, the more reliable method is to sow into pots and transplant seedlings when they are about 20cm high. It’s also possible to buy seedling leeks from nurseries or by mail order.
Can you plant leek seeds straight into the ground?
During March or April, sow leek seeds thinly, 1cm (½in) deep, in rows 15cm (6in) apart. If you don’t have space outdoors or only want a few leeks, you can sow in modules indoors, then transplant outdoors later. Sow one seed per module.
Are leeks hard to grow from seed?
Home-grown leeks are far superior to those bought in shops and versatile in the kitchen. They’re easy to grow from seed, and if you sow at intervals from February to June, you can harvest them from late August, through winter until the following February.
How do you germinate leek seeds?
To grow leeks from seed, fill small pots or seed modules with potting mix that has a fine tilth – seed compost would work well. Sow one seed per pot or module and cover with a fine layer of potting mix. Keep the soil moist, but not overwet. The seeds should germinate within two weeks.
How long does it take to grow leeks from seed?
Most leeks require a long growing season of about 120 to 150 days, and a minimum of eight hours of bright sunlight daily. Some newer cultivars require as few as 90 days to maturity, and these may be most suitable for Minnesota conditions. In northern climates, start seeds indoors in late February or March.

Should I cut the tops off my leeks?
Trimming the main growing shoot(s) helps to prevent them becoming hopelessly leggy and tangled. It also encourages the growth of new leaves from the basal plate at the bottom of the leek, and that’s what you want: a thickening of each seedling to roughly ‘pencil thickness’, ready for planting out in June or early July.
Can I grow leeks in pots?
Leeks are well-suited to growing in pots. Guidelines suggest spacing leeks 7 inches (20 cm) apart, but they can be packed closer when growing in pots, down to 2 inches (5 cm) but the less space you give them, the smaller they will grow.
Should I soak leek seeds before planting?
As a general rule of thumb, your seeds will sprout even if you don’t soak your seeds before planting, but with soaking the germination time decreases, and the germination rate increases. Seeds that have a continual flow of moisture to uptake have much higher chances of success.
Do you soak leek seeds before planting?
After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced, which means you can have happy, growing plants faster.
Do you need to soak leek seeds before planting?
Growing Basics
The amount of time your seeds should soak in cool water. Soaking is how we begin the sprouting process in most cases. How often your seeds should be watered. Rinsing thoroughly and then draining as much water as possible are key components to growing great sprouts.
How many times can you regrow leeks?
Will Leeks Keep Regrowing from Cuttings? Yes, but not forever. Leeks are considered biennials, meaning they have a 2-year life cycle. In the second year, after a dormant cold period, leeks will go to seed, producing a long seed stalk and large flower head.
What can you not plant with leeks?
A side note on what to grow next to leeks should include what not to grow near these plants. Apparently, beans and peas do not thrive near any member of the onion family.
Can leeks survive winter?
Generally, leeks can survive the winter. Most leek varieties can survive deep frosts down to 12.2°F (-10°C) without any protection. They can also survive colder temperatures, depending on snow (insulation), rain, and wind exposure and length of exposure to those very cold temperatures.
Do leeks multiply?
Leeks have long, strap-like leaves and many develop a roundish bulb. This plant is a true perennial, even though it is generally referred to as a biennial. It multiplies by means of small lateral growths and often develops a roundish bulb at the base of the main growth.
Do leeks need full sun?
Luscious Leeks
Grow leeks in a sunny, open position in well-dug soil that’s had plenty of organic matter added to it. The fungal disease rust can be a minor problem from summer onwards, so look out for varieties described as ‘rust resistant’ and make sure you leave enough space between plants for good air movement.
How long can leeks be left in the ground?
Leeks are a type of vegetable that you can leave in the ground for up to 6 months. You will have to replant them every year, but they’ll come back. Read more in detail here: do leeks come back every year.
Should you start leeks inside?
You can direct-seed leeks, or start transplants indoors. Long-season varieties are best started indoors. Start transplants about 8 to 10 weeks before last frost date. Sow seeds in flats about ¼ inch apart and ½ inch deep.
Do leek seeds need stratification?
Leek seedlings are generally ready for a week of hardening off about seven weeks following germination. A period of hardening off before transplant, or gradually exposing young leek plants to the light, temperature and moisture they will experience outdoors, is key to preventing shock.
What temperature do leek seeds germinate?
GERMINATING LEEK SEEDS
Leek seeds will germinate in a very wide range of temperatures, from 7.5°C to 32°C (45°F to 90°F). The optimum for germination is a daytime temperature of about 21°C (70°F) and several degrees lower at night.
