Wow, nice job! That is a pretty impressive garden. I know what you are saying about the Zucchini. I had to manually pollinate my plants and almost overnight I suddenly had a couple of huge zucchini laying on the ground. It was crazy. My tomatoes are producing a lot, but the leaves are all turning brown and dying. I am not sure how much longer they will be able to hold out.
We have a few zucchini plants close together, so maybe the insects pollinated for us. Hope you get some tomatoes. I need to check on ours today.
