Growing in a Grid (2)

20190511 (6)

Though I have, technically, been attempting grid gardening for two years, it’s been on a more informal basis; a shove it all in and hope it grows basis.  This has worked, but only up to a point.

There are websites and books out there that have already calculated the optimum number of plants that should grow in one-square-foot.

If you want to sow garlic, one square foot (foot-square?) will support nine. Sowing parsnips? You can sow sixteen in one square.  Chard? You can only sow four seeds or seedlings. Potatoes – just one.

If I translate that to a large-scale raised bed, then a way of measuring the area and using the correct spacing is necessary.  I spotted something on the internet a while ago, but it wasn’t too difficult to draw up my own plan, though it doesn’t cover every variation.

InkedSEEDING SQUARE - SQUARE FOOT GARDENING (2)_LI

This is the template my husband used to make my board out of plywood scraps from the shed.

The square is 12 x 12 inches (well it is called square-foot gardening).  I drew diagonal lines corner-to-corner and measured a one-inch border around the outside, then worked out the distances between each set of holes by trial and error – and a pencil and rule(r).

16 holes (green) are 8 centimetres apart, 9 holes (blue), which include the centre are 10 centimetres apart, 4 holes (red) are 14 centimetres apart.

And here is the finished object.

It’s not pretty, but it doesn’t have to be.  It will do the job, and I have a spare. I’ll use a small length of cane as a dibber – to mark the space when planting seedlings, or measure the correct depth when sowing a seed.

I just need to make sure I have a list of how many of which vegetable seed per square.

There may be times when I just make it up!
