The only thing you have to think about with growing cucumbers after peas is the timing. I tried it last year and didn't like it. I direct seeded the cukes after I cut down the peas and the cukes didn't start producing until late in the summer. If you direct seed the cukes while the peas are just slowing down in production it might be better.

On a different subject, you have to be careful with lemon balm. It's in the mint family and will spread.
