Is the top of the drawing against a wall, or is it open space? You need room to get in and harvest, and 1 foot isn't much space. Corn will get tall, so should be north of the other vegetables. What zone do you live in? I see some vegetables that wouldn't be grown in the same season in my zone, but might work well for you. For example - broccoli is a cool season veg. and zucchini is a warm season veg.

Agree with lgteacher. And spinach is a cool season veggie and tomatoes are a warm season veggie. etc.

Top of the drawing is open space and there's actually several feet not represented. Alot of things im planning on planting later on summer for fall. I'm in zone 7 (Philadelphia)

I would stake the cucumber. I've even seen video of people pruning and single stalking their cucumbers to keep them within a square.
