Welcome, Tammy (
@dreemesicl ) !
I'm way farther north than you are and I grow all sorts of tomatoes (and definitely get more than 1 tomato from them before the end of the growing season
). I plant mine out around the beginning of June, so I would think you can probably plant out now, or even earlier in May, in Cincinnati.
A couple of smaller-fruited ones that we always grow are Juliet and Fourth of July. For larger tomatoes, Celebrity is very popular (although it didn't do the best for me; but that may have been because we had particularly cool weather the summer I tried it). If you know someone nearby that grows tomatoes you could ask them what kinds they like to grow, or ask at the garden center where you go to buy your plants. Others that I really like are Country Taste, Viva Italia, and Pruden's Purple -- but I don't know if those are commonly available for sale, I've been starting my own plants from seed for a long time. I hope you have a great garden season!
