That entirely depends on your climate.

Tell us your zone so we can give you ideas.

like above depends on where you are located like for here in CA right now the only thing i think you could plant where i am is corn or more tomatoes or squash or pumpkins or water melons mostly anything summer related due to the fact that we will probably see 4 more months of warm dry sunny weather here in the central valley. right now I'm struggling to get my broccoli to finish to harvest since i planted late but there are doing okay and the heads are starting to develop even though we been having some above average temps lately.

In my zone: starting Savoy cabbage next week for winter harvest, mid July: fall carrots, beets, late beans and summer squash, early August: turnips, escaroles, Asian radishes, early Sept, fall/winter lettuces. Still lots of time here for lots of stuff.
