I harvest mine when it looks like spinach! Seriously, I just cut outer leaves, a few from each plant, as soon as it looks big enough to eat. My spinach harvest typically lasts a month or so, depending on the weather. I sometimes (depending on how crazy my life gets) do a second planting in maybe mid July, remembering that spinach likes cold weather best and your second harves will probably be smaller and shorter than the first. When to do a second planting also has to do with your climate. Check with your local cooperative extension office, they should be able to tell you planting times for your area.Anny said:How do you know when to pick your spinach??
If I just pull the leaves off will the plant continue to grow more??
