Spinach seeds are great to grow in your garden or allotment as its a superfood that is full of vitamins and nutrients. Spinach can be eaten raw when freshly picked, or it can be sautéed and cooked in with many different dishes. Spinach seeds can be sown direct to the planting site from May to October, and should be ready to harvest from March to September the following year. Ensure that they are well watered, especially during the hotter weather, as this will prevent the crops from bolting. Spinach is one of the easiest types of vegetable seeds to grow, so great for beginner gardeners and the more experienced.
