Hello everyone! It's my first year gardening in a raised garden bed. Currently I have cucumbers, tomato's, bell peppers, and yellow squash. Everything but the squash was producing well, but when the squash began to produce, the cucumbers began to get brown spots on the leaves, but not on the fruit. The leaves then began to die, and spread to the other vines. Now the tomato is also starting to die. The bell peppers are unaffected. I know this season is coming to a close but is this something I need to worry about for next season? Thank you everyone!

Greg
