Plymouth spinach is an incredibly uniform hybrid type with regular stems that is easy to harvest and would be excellent for bunching for market. The growth is upright, and leaves are rounded when young and become more arrow-shaped at maturity. Plymouth is fast growing, slow to bolt, and is strongly disease resistant. The dark green leaves have a succulent texture and mild flavour, making it an all around great choice.

We Recommend
We Recommend: Monstrueux de Viroflay (SP713). Most of the spinach varieties we offer are hybrids that mature early and resist bolting. For growers, these may make the better choice. But we also love the open pollinated heirloom Viroflay, which stands apart from the rest for its sheer size. And the leaves stay tender and delicious even when the plant is fully mature. This is a very nice spinach for the home garden.
For Urban Gardeners: Try Space (SP704) in containers or even window boxes. Space is very compact and upright, holding its leaves skyward for easy harvesting. Plus it’s super fast growing and very tasty.

Spinach does best in cool weather. Direct sow in the period four weeks before, and three weeks after the last frost date. Spinach will bolt once days get long and hot. Some varieties grow enough to harvest before they bolt. For continuous supply, plant every 3 weeks.
Sow again in the middle two weeks of August for a fall crop that, if cut at the soil level, will come back early the following spring where winters are mild. Shade summer-sown seed beds, keep very well watered, and sow more seeds than you need, as warm soil will reduce germination rates marginally. Thin seedlings, and use cloche protection as cold weather approaches. Late sowings like this can be harvested into December – in mild winters if cloche protection is provided.
Optimal soil temperature: 5-20°C (45-70°F). Seeds should sprout in 7-14 days.
Starting
Starting
Sow seeds 1cm (1/2″) deep, 10 seeds per 30cm (12″), in rows 30-45cm (12-18″) apart. Thin to at least 5-8cm (2-3″) between plants, or further if you want larger leaves.
Days to Maturity
Days to Maturity: From direct sowing.

Ideal pH: 6.0-6.5. This heavy feeder requires rich soil. Dig in ¼-½ cup balanced organic fertilizer beneath every 1m (3′) of row. Overwintering spinach requires well drained soil.
Harvest
Harvest
For baby greens, pick when the leaves are 7-10cm (3-4″) long. Individual leaves can be picked at anytime, until the plant has started to bolt. Cut the whole spinach plant just above soil level.

Diseases & Pests
Diseases & Pests
Pale, soft tunnels on leaves are probably leaf miner damage. Prevent by covering with floating row cover. You can kill the little insect causing the damage by pinching it inside the leaf. Destroy any affected leaves. Downy mildew is a fungal disease that causes greyish mould on the leaves. To avoid it, provide ample ventilation and avoid overhead watering.
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.
