Thanks to our 2 years worth of experience growing squash in Oregon, we recognized and addressed the powdery mildew on our patty pan plants immediately! Whew – that crisis averted! Now there’s the blossom end rot nonsense to worry about.. It looks like we’ll basically lose all of the first fruit from our roma plant and some from the heirloom plant as a result. Apparently it was caused by abnormally cool temps that hit right when the plant was starting to fruit and there’s really nothing to be done about it. We have more, healthy fruit coming along – sad to see how much we would have had..
