How to grow spinach

Spinach (Spinacia oleracea), a member of the goosefoot family, grows as a low, dense rosette of dark green leaves emerging from a central crown, reaching roughly 8 to 12 inches in height. Home gardeners prize it as one of the most productive leafy crops that can fill a bed in spring and fall, occupying ground that would otherwise sit idle while the soil is too cold for most warm-season vegetables. A fall planting commonly returns better-tasting leaves than a spring planting, because the transition from warm to cool temperatures is more predictable and slower to trigger the plant's reproductive response.

The hardest part of growing spinach is accepting how narrow its productive window actually is. Bolting is driven by both rising temperature and lengthening daylength, and a spring planting delayed by even a week or two can leave the plant rushing to flower before a worthwhile harvest is taken. Leaf quality deteriorates as soon as seed-stalk formation begins. Dry, moisture-stressed soil compounds this further: spinach in poor growing conditions bolts faster and produces bitter, tough growth. The second-year gardener who treats the timing as flexible often ends up with seed stalks where dinner should have been.
