To grow spinach in your garden, you need to prepare the soil for planting the seeds. Soil should be moist, preferably around 40 degrees F, and well-drained. Spinach is best suited for partial shade. For best results, sow the seeds a couple of weeks before the last frost. You can plant the seeds directly in the soil, or start them in starter pots. If you choose to plant them in a starter pot, make sure that the soil is well-prepared and that it has no debris or mold. In a shallow drill, cover the seeds with a quarter inch of finely-sifted soil. If you are planting spinach in a starter pot, add one or two cups of well-drained organic fertilizer to the soil before you plant the seeds.
You can plant spinach seeds anywhere between mid-April and early-July, but cold weather is ideal. Spinach is a cold-hardy crop and can survive overwintering in sub-zero temperatures. Plant seeds directly into the garden between March and April. During the growing season, spinach can be harvested every two weeks or more, and you can harvest the leaves before they bolt, so you'll have more than enough spinach to eat throughout the winter.
You can start spinach seeds indoors, but transplanting seedlings is a hassle. In cooler climates, spinach seeds can be started indoors but the young plants will not survive the transplant. For northern regions, harvest spinach in early spring. If you want to prolong your harvest, cover the plants with a thick layer of mulch and a cold frame. You should also remove the young spinach plants from the soil when temperatures reach 40 degrees F.
The seeds of spinach are a highly nutritious crop. They are a valuable source of nutrients and are grown for both fresh market and freezing. As a result, it grows rapidly in your garden. In general, you can harvest the leaves in just six weeks. For optimum harvest, use the older leaves in stir-fries and soups. If you want to grow spinach, make sure to plant seeds in the springtime. Remember, it takes 45 days for spinach to mature fully.
You can plant spinach seeds in containers, but they don't require an overly demanding soil. However, spinach can benefit from an organic nitrogen-based fertilizer at planting time. It can also be helped by compost. While spinach plants do not usually suffer from major problems, it should be spaced out appropriately to allow proper air circulation. To prevent mildew, space the seeds at least eight inches apart. Downy mildew spores will stay in the soil and infect the spinach again.
