How to divide a bed 13' x 10'?

I thought all flower beds were random except council planting in public spaces.

My flower borders are random, though a few years ago I did try to link it together with repeating plants throughout some.

The dahlias for cutting didn't work when planted randomly through borders. Staking was a pain, and it takes twice as long trying to pick things.... and other flowers can get damaged trying to do it.

The white/mauve flowers are Radish, Yellow are land cress and kale and the cream & brown are rocket. You know what the orange ones are (I hope).
