There’s two schools of thought with North-South rows: one says the seedlings that are doing better should go at the back (North) because they need less help, other says the seedlings that are doing better should go at the front (South) so that they do even better, and devil take the hindmost.

Plan now and maybe start some rough works if needed then start sowing and planting come spring
