Spinach is most productive in cool weather. Grow in cool spring conditions and sow again in late summer for a productive fall crop. After seedlings reach 2 to 3 inches tall, thin out every other plant (and enjoy in early salads) and keep thinning in this fashion until plants are spaced 5 or 6 inches apart.
HARVEST AND USE
Either harvest individual outside leaves from well-established plants and let regrow, or harvest entire plants. Keep spinach plants well watered and weeded and fertilize these heavy feeders several times as they leaf out and especially after harvesting outside leaves. Combine well-washed and dried leaves with your favorite garlicky salad dressing; spinach pairs well with hearty dressings like the traditional hot bacon dressing. Good spinach salad additions include thinly sliced sweet red onions, sliced radishes, thin wedges of red apple or orange segments, toasted nutmeats, chopped scallions, crispy bacon bits, hard-cooked egg quarters and finely grated hard cheese.
