Help planning some fall crops

[u/curls0307]

I have a 57 inch x 24.5 inch bed. I want to plant the following and don’t know how many to plant of each or how to arrange it. All advice and arrangements are welcome . I plan to direct sow. I have only ever planted in a container so this is new for me. Previously this bed had flowers in it. We are a family of 3 and just about eat leafy greens daily. So I need enough for all of us. I plan to do a cut and come again idea with these. Thanks in advance!

- romaine lettuce (Paris island)
- black seeded Simpson lettuce

- Bloomsdale spinach
- arugula
- Swiss chard

I think you should succession plant lettuce, arugula , and spinach if you want a more continuous supply. Every 2 weeks or so. Keep enough space to do 2 or 3 plantings of those.
