My cucumber leaves have started to get brown spots -- worsening in some areas. What is this? What (if anything) should I do?
I have one cucumber that looks just fine, one that is partially grown (not pollinated enough?), a bunch that I didn't realize needed pollination assistance (so they probably won't grow at this point?), and perhaps a few more to come, so I don't know that this is damaging the veggies (is it!?).
is it on the leaf or is the leaf shrunk in and like paper in those spots? I had something very similar happen to quite a few of my plants this year and what it was was that my b\f was going out at about 1 in the afternoon and watering while it was about 95degrees outside and the sun was blasting on it and the plant sunburned in the spots where the water droplets sat. so that's a possibility, I don't what your temps and conditions are like up there.
I think it's more like the shrunk in/like paper in those spots -- it's not like a fungus growing on it. I wasn't watering during the day, but I wonder if given how the leaves are one on top of the other (give how it's staked in the windowbox), if maybe morning dewdrops would cause that? It was pretty hot during the day in the summer here.
