Timing
Timing
Start summer/fall harvest leeks 6-8 weeks before the last frost date, in flats indoors. Start winter harvest leeks indoors from March to mid-June. In mild winter areas, start them in a humus-rich nursery bed outside, and then transplant. Optimal soil temperature: 10-25Β°C (50-75Β°F). Seeds should sprout in 10-16 days.
Starting
Starting
In flats: Sow seeds 5mm (ΒΌβ) deep, about 1cm (Β½β) apart. Transplant when 20cm (8β³) tall. Space 20cm (8β³) apart in rows 45cm (18β³) apart. Rows can be as narrow as 20cm (8") if planting in raised beds or other situation where weeding will be simple.
Growing

Ideal pH: 5.-6.5. Leeks have short roots, so the benefit from fertile soil with lots of compost and Β½ cupΒ balanced organic fertilizer worked in beneath each 2m (6β²) of row. Traditional garden wisdom recommends using a dibber to make holes 15cm (6β³) deep. Transplants are then set at the bottom of the hole and the hole is left unfilled β rain will fill it in as the leek grows. To blanch further up the stem, hill soil up around the stem as the leek grows, or mulch with straw.
However, the wise and much loved garden writer Linda Gilkeson asserts that there is no need to plant leeks into holes or trenches. She recommends transplanting the seedlings only at the depth of the soil plug they grow in. They will still produce nice, tall, blanched shanks, with no soil grains between the leaves.
In late fall, mulch around leeks as high up the stems as possible. If the forecast is for weather below -10Β° (14Β°Γβ cover them with a blanket or tarp.
Days to maturity:Β From transplant date.
Harvest
Harvest
Dig at any size, as needed. If winter harvest leeks freeze solid, wait until they thaw out during a warm spell to harvest.

West Coast Seeds is a family-owned company that embraces an organic lifestyle. A group of imagination catalysts and passionate educators, dedicated to producing products and services that better the environment. As part of our mission to repair the earth, we aim to inspire and empower people to take responsibility for the state of the planet. For us, organic is about much more than saying no to chemicals, it is about saying yes to building a healthy soil for the future.
For over 35 years, we have upheld our strong reputation as a leading seed supplier, seeking out the highest quality untreated seeds for organic growing and putting them through rigorous independent testing. We built our company on the exchange of generational wisdom in a masterclass community of newbies and masters alike. Our world may have changed, but our commitment to our people, our customers, and our planet has not.
Weβre a values-based business that has blossomed into a lifestyle ethos, with products that support seeders, feeders, keepers, and the tiniest of creepers. Our mission? To mobilize the next generation of gardeners with products that nourish soil and grow vigorous, sustainable gardens. We believe all plants should be grown without the use of chemicals, and that the seeds we supply are an important component of regenerative gardening.
We donβt just offer seeds, we offer experience, insight, and understanding. From timeless garden wisdom to new tech know-how, this is learning on the job: knowledge gleaned not from the pages of a book but from burying our fingers in the soil. We test, experiment, observe and adapt, never happier than when we get to share what weβve learned with others.
Gardens donβt just grow seeds. They grow minds and imaginations, people and communities. Our vision encompasses both the micro and the macro. We eat locally, protect pollinators, teach people to grow from seed, and support regional biodiversity. We think big but act small and deliver unexpected impact β always with community and purpose.
At West Coast Seeds we believe in the power of small and that little can be large. Like the tiniest seed germinates to evoke incremental change with massive potential, so to can our community of gardeners and growers together. Gardeners are the earthβs stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
