Planting Details
| Row Spacing | 12" |
|---|---|
| Seed Depth | ½" |
| Seed Spacing | A group of 3 seeds every 6" |
| Thinning | When 2" tall, thin to 1 every 6" |
| Germination | 5–10 days |
| Start Indoors | Not recommended; roots sensitive to disturbance. |
| Direct Sow | RECOMMENDED. 4 to 6 weeks before your average last frost date, and when soil temperature is above 40ºF; ideally 50°–75°F. Successive Sowings: Every 3 weeks until 4 weeks before your average first fall frost date. If mulched, spinach can overwinter in sub–zero temperatures. Soil temperatures above 85ºF halt germination. Mild Climates: Sow in fall for cool-season harvests. |
| Growing & Harvesting | Pick individual leaves from outer edges of plant as they become big enough to use or cut the whole plant 1" above the ground; new leaves will be produced. When picking individual leaves, also removing the leaf stem at the same time is best; this reduces vulnerability to disease during die-back and conserves plant energy. Harvest before the plant sends up a flower stalk (bolting). Just prior to bolting, leaves take on an "arrowhead" shape, adding small keel shapes to the base of the leaf. |
