Our Poor Tomato Plant

This little tomato plant was given to Kathy by someone she knew, and we were going to transplant it to the garden by the driveway.  We did keep it watered during the heat and I did add a bit of plant fertilizer, but it sat and sat, and some of the tiny tomatoes have ripened.  I wonder if it is too late to save this?  We need to get it transplanted and if we do I will report back to you.
