Organic Salad Tomato - Scotland Yellow

I got several ripe & more to come but this really isn't suited for outdoor planting as advertised. I started my tomatoes in February inside & planted out in April. The tomatoes I put into upside down bags in my polytunnel have done the best. Those outside have only flowered & no fruit. I've also had a lot of trouble with the tomatoes rotting on the vine but I suspect that is from the unusually humid weather we've had this year.
