42 days. Open-pollinated. The standard crinkled-leaf spinach. Very good cold soil emergence. Much better as a fall crop than in spring when it bolts in the heat. Spinach is a cool-weather crop. Plant seeds directly into the garden, four to six weeks before the last spring frost. To get better and quicker germination, soak the seeds for several hours before planting. Spinach grows well in soil that is near neutral in pH between 6.5 and 7.5. It is not a heavy feeder, but performs best in soil that is rich in organic matter. Spinach is rarely troubled by disease problems or pests.
Harvest spinach as you would lettuce. Either cut off all the leaves about an inch or so above the soil level and let the whole plant grow back (this technique will usually produce two or three crops), or simply harvest the largest leaves as you need them.
