Noble Giant spinach grows best in cooler weather between 45°F-75°F. They do great in containers and small gardens. Bank on Seeds recommends direct seeding.
If Direct Seeding
- Direct seed outside 2 weeks before last frost date; or
- Direct seed into a container 8-10 inches deep and wide anytime of the year. It can be placed outside when the temperature is between 50°F-75°F; or
Begin the growing season early and start the spinach seeds indoors in trays or pods 6 weeks before the last frost date. Germination is best and fastest between 55°F-65°F. It can be transplanted outside 8 weeks later.
Sow spinach seeds ½ inch deep and 2 inches apart with rows spaced 12-18 inches apart. Germination will take 4-9 days.
Noble Giant likes well-draining soil with lots of organic matter. They also like partial sun but can tolerate full sun if not too hot. Water regularly to keep the soil evenly moist and do not let it dry out fully. Check the top 2-3 inches of soil and if it is dry, then water it.
Apply mulch to the top of soil to retain moisture, regulate temperature and deter weeds. Fertilizer is not required but if necessary, use aged compost, manure or 5-10-10 fertilizer every 6-8 weeks.
Noble Giant spinach is full grown in 46 days. Snip the outer leaves as you need for salads and garnishes or wait until full maturity to cut the whole plant for cooking.
