Best slicing tomato for Central MD
I have an urban garden in Central Maryland (Baltimore City). It is about 5'x8'. I have never had much luck growing slicing tomatoes. I grew Sungold last year, and a yellow pear the year before, both did amazingly well. I know slicing tomatoes won't have near the yields of the smaller varieties, but I was hoping for a plant that gave me more than 1-2 fruits per month!
Can anyone suggest varieties (preferably heirloom) that do well in Central MD? So far I have tried Early Girl and Better Boy.
