Planting spinach

How it is worked out

• In a raised bed, spinach stand 4 in apart each way, which is 9 to the square foot. Every plant is within reach of the bed’s edge, so no room is kept for paths.
• In the ground, they stand 4 in apart in rows 12 in apart, with room to walk and hoe between the rows.
• Plants are kept half a spacing in from the bed’s edge, and the rows are centred in the bed.
• Each plant is drawn at the size it grows to, 7 in tall and 8 in wide, so you can see how the bed fills in.
• Spinach bolts in heat, so it is sown in early spring and again in fall.
• A raised bed’s soil is its length times its width times the height of its frame. The frame is counted in 2×6 boards, one course round the bed for every 5½ in of height.
• Mulch for a bed in the ground is its area times the depth you choose.
• Row spacing and planting depth follow the home garden guides of Clemson and the University of Florida extension services. Raised bed spacing follows Virginia Cooperative Extension’s intensive spacing.

We set out and count the plants and spacing you pick, close enough to plan a weekend and a trip to the nursery. The plant’s tag and the place you live settle how far apart it wants to be.
