Timing
Timing
Direct sow late spring through summer, or sow when cucumbers are transplanted, to coincide maturity for pickling. Dill tends to bolt if transplanted, so it is best direct sown. Stagger the harvest by sowing every 2-3 weeks for a constant supply of fresh leaves. Optimal soil temperature for germination: 15-21°C (60-70°F). Seeds should germinate in 10-21 days.
Starting
Starting
Dill seeds need some light to germinate. Sow seeds no more than 5mm (¼”) deep in rows 45cm (18″) apart. Thin the plants to stand at least 15cm (6″) apart.
Growing
Growing
Ideal pH: 5.0-7.0. Grow in moderately rich soil in full sun. Water and feed regularly, and stop any overhead watering once plants are 60cm (24″) tall to prevent issues with mildew forming on the leaves.
Harvest
Harvest
Begin harvesting the tasty leaves once plants reach 15cm (6″) tall. About 12 weeks after sprouting the seed heads begin to form. When the first seeds have turned brown, cut the whole head and hang it upside down for the drying seeds to fall out into trays or paper bags. Dill leaf loses most of its flavour when dried, so freeze it in ice cube trays filled with water for use all winter.

Companion Planting
Companion Planting
Dill improves the health of cabbages and other Brassicas, and is a very good companion for corn, cucumbers, lettuce, and onions. Dill attracts ladybugs, lacewings, and the parasitoid wasps that feed on garden caterpillars. At the same time it repels aphids and spider mites. Avoid planting near carrots and tomatoes.

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.
We’re 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 don’t 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 we’ve learned with others.
Gardens don’t 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 — 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 earth’s stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
