Welcome
heatherdawn1009!! You will love it here
I see you have four vines on the list Cantaloupe, Cucumbers, Squash, and Watermelon. I am assuming you are planning these for the trellis. I have grown cucumbers on a trellis and it works great! The melons will work too, but you will need to make a sling for the fruit. That can be fun!
I don't grow many veggies. But I do know Broccoli is a cool weather crop. So either spring for fall is best for that.
My mom used to do square foot gardening quite a bit. I will call her over to see what recommendations she has.
@abhege what say you?
