Hi I'm Jarrett of Stone Soup Farm in Belchertown and this is how to grow spinach. Spinach is a cold loving crop and it is best to plant in the Spring or the Fall when it will likely experience freezing or near freezing temperatures. To plant spinach first prepare a well groomed seed bed like this that has plenty of soil fluff and is damp. The easiest way to plant spinach is to have a common garden seeder like this where you can put the spinach seed in the hopper and you just go ahead on a well prepared surface and the seeder will automatically dump seeds at the right spacing right in a row like this and you could do several rows at about one foot spacing, make sure to water that in and keep it weed free throughout the season and the spinach should come up and be ready to harvest in about six weeks. If you do it in the Fall spinach is one of the only common garden vegetables that is Winter hardy in Northern areas and if you do it in the Fall you can get a good harvest off of it and if you keep it nice and weed free you can over Winter it so that next Spring it will be one of the first things to come up out of the ground, you won't have to replant it, it will be really good, especially good the next Spring so I highly recommend trying that too. I'm Jarrett of Stone Soup Farm and that's how you grow spinach.
