I planted a bunch of bush beans in the places that I pulled my lettuce and spinach. I did this last year and it worked well. As an experiment, I put in some swiss chard, because the package said it could be planted in July. The other posters here seem to plant that in the early spring, so I may be way off base with that one. I'll post a follow up later and let you know how that goes. I have never grown it before. I planted about a week ago and I am going to need to thin soon, because it germinated right away.

I'm in northern IL and just planted more bush beans this morning!

same here! I had some open space so I planted pole beans yesterday and golden beets the day before.
