Spinach is a garden vegetable that requires cool temperatures to germinate and grow. Many gardeners plant spinach in the early spring for one of the first vegetables to harvest from the garden in late spring. Wise gardeners who enjoy fresh spinach will also plant spinach in the late summer for one of the last vegetables to harvest from the garden in the fall.
Prepare the planting area in the late summer or early autumn. Work the soil with the garden spade down to a depth of approximately 6 inches. Add 1 or 2 inches of compost to the top of the soil and work the compost in with the garden spade. Rake the soil smooth to finish preparing the area.
Make rows for the spinach with the trowel that are 1 foot apart.
Plant approximately 12 spinach seeds along every foot of garden row. Cover the spinach seeds with ½ inch of garden soil.
Water the spinach seeds lightly immediately after planting. Keep the soil evenly moist during germination.
Thin the spinach seeds when they are 1 inch high. Pull weaker spinach plants so that the strongest spinach seedlings are approximately 4 inches apart.
Harvest the spinach plants when they are about 4 inches long and 3 inches wide. Smaller spinach leaves will be more flavorful than large spinach leaves.
Cut the spinach plants down to the soil level before they flower because the leaves that remain on the plants if the plants bloom will be bitter.
