Giant Winter was bred specifically for autumn, winter, and early spring harvests. It is the most cold hardy spinach, and will thrive in a winter greenhouse or polytunnel, our outdoors under a layer of mulch. Or direct sow in October and November for a very early crop from February through April. This old heirloom grows to the size of Swiss chard leaves. Its leaves are dark green and slightly savoyed, and vaguely triangular in shape.
Latin
Spinacia oleracea
Family: Amaranthaceae
Difficulty
Easy
Season & Zone
Season: Cool season
Exposure: Full sun to partial shade
Timing
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
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
From direct sowing.
Matures in 45 days
Growing
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
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.
Seed Info
In optimal conditions at least 65% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 400 seeds, per acre: 174M seeds.
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.
