Spinacia oleracea Partial Shade Soil pH: 6.0- 7.5
Spinach seeds should be sown about 1/2 inch in depth and spaced 2 inches apart in either beds or rows. Under normal temperate conditions the seeds will germinate in 5 to 9 days, although this varies slightly from cultivar to cultivar. Spinach will produce well in cool fall weather, but it's seed to germination in hot conditions of late summer hamper germination and reduce the survival rate of sprouts. Sow seed heavily, because the germination rate drops drastically in warm weather, and water the seed beds frequently, even twice daily in warm weather, watering helps to cool the soil, a light mulch is also advisable. Cover the plants with shade cloth or a Floating row cover if the temperature goes above 80F.
Spinach, when properly grown produces large yields of vitamin-rich, dark green leaves that are excellent for salads and cooking.
Spinach plants form a hefty central taproot, so be sure to loosen the soil to at least a foot in depth prior to planting. Spinach also requires moisture, not excessive, but ample moisture. As with all plants grown for their foliage, a nitrogen-rich soil is also essential.
Sow spinach seed early, as early as 5 weeks before the last frost date or as soon as you can work the soil. If you prepare the soil the previous autumn, you can place the seeds in the thawing ground. In areas with a extended cool spring, make plantings at weekly intervals until mid-May.
In warm climates, spinach should be planted in a shaded area, behind a tall crop such as corn is a good idea. Using cold frames or heavyweight row covers, you can sometimes grow spinach all winter long.
