Growing Information:
Spinach
CULTURE: Spinach grows in a wide range of soils if moist and fertile, but is sensitive to acidity. pH should be at least 6.0, preferably 6.5-7.5. SOWING DATES: Spinach germinates best in cool soil. Begin sowing in early spring as soon as the ground is ready. Summer sowing in hot soil-over 85°F (30°C)-risks low or erratic germination! Sow late in July into September for the fall crop. Spinach can also be planted from September until freeze-up for an early harvest the following spring; floating row covers offer effective winter protection. PLANTING And HARVEST: For bunching and full size: Sow about 9-10 seeds/ft., 1/2" deep, rows 12-18" apart. Harvest spinach full size but before bolting, cutting just below root attachment for "rooted spinach," or cut higher for "clipped spinach." For salad mix (small clipped leaves): sow in a 2-4" wide band, 3/4" apart, about 40 seeds/ft. Clip small leaves in 3-5 weeks, depending on time of year and speed of growth. Triple-rinse leaves, sort out cut and broken leaves, and package. For a continuous supply, sow every 7 days. STORAGE: Store at 32°F (0°C) and 95% humidity 10-14 days. AVG. DIRECT SEEDING RATE: For full-size leaves: 220'/oz., 100'/1,000 seeds, 5 oz./1,000', 8.3 lb./acre at 10 seeds/ft. in rows 18" apart. For Salad mix: 50'/oz., 25'/1,000 seeds, 35 lb. (1.2 million seeds)/acre at 40 seeds/ft. in rows 18" apart. GRADED SEEDS: Standard on all varieties except where noted. SEED SPECS: SEEDS/OZ.: (for Size 6-8 seeds, which are usually supplied) 1,550-3,750 (avg. 2200). SEEDS/LB.: 25,000-60,000 (avg. 35,000). PACKET: 5 gm. (approx. 1/6 oz., avg. 385 seeds, sows 35').
