Hey JerseyJohn61 maybe you could answer MtnClimber’s question, in his post #68, about cross-pollination in heirloom tomatoes.
It has been a cold year so far here at 8,500 ft in the Colorado Rockies! I have to hold back laughter every time my leftist (retired social worker) neighbor complains about the cold weather and blames global warming. On July 4th it struggled all day to break 60F and is into the 40’s most nights. The only veggies really growing well are cold tolerant like potatoes and turnips. varieties that like warmer weather like tomatoes, squash, eggplant and peppers are still growing very slowly. Those 4th of July tomatoes were only about 3 inches tall yesterday. I gave everything a light feeding of 10-10-10 a few days ago so I am hoping that will speed things up a bit.
