When you pick tomatoes choose various stages of ripeness so that you don't end up with more ripe tomatoes than you can use in a given time frame. However, this doesn't always work if you have planted tons of tomatoes. Good luck, I have been there with making every tomato recipe I could find, giving them away to the point where friends and family said they couldn't use anymore!
Keep the basil flowers deadheaded or the plant will go into decline. I cut quite a bit today and I can't use it right away, so it becomes a decorative arrangement plunged into a pitcher of water. It will hold for a couple of days until I can make my pesto recipe. This is a recipe given to me by my daughter-in-law because the children would not eat my pesto but went back for seconds with hers. Mine was the James Beard adult recipe, a little too strong not only for children but for some adults.
