If Popeye, the spinach-loving cartoon hero, somehow contacted GardenZeus for garden advice, we would not hesitate to suggest that he plant a large portion of his garden in spinach to ensure the supply he needs to prevail against Bluto, his spinach-deficient archenemy.
Where do you fall on the Popeye-Bluto spinach scale? For occasional eaters of spinach toward the Bluto end of the scale, a few plants per person may be sufficient. For those in the middle of the Popeye-Bluto scale, regular eaters of spinach or seasonal afficionados who go through bouts of spinach enthusiasm that may last days or weeks at a time, 10 to 15 plants per person with successive planting every 3 or 4 weeks during your growing season should be sufficient. For true spinach lovers who join Popeye at the spinach-addict end of the spectrum, 20 or more plants per person with successive planting at least every 2 to 3 weeks may be necessary to maintain an ample supply.
