I do think the heavy rain either contributed to the problem or caused it. Some of the tomatoes split on the tops which Google told me was caused by uneven watering which I interpreted as heavy downpours vs regular watering. They suggested mulching around the plants for that but I'm finding that our plant skills are woefully inadequate and we didn't even attempt that.
The containers do have drainage holes but with all the rain, I'm not sure they were adequate either.
Thanks, everyone for your input. At least I don't feel like our attempt failed or that it was something that we did and we did get some very good tomatoes. I'm not sure gardening will ever be on any of our resumes though. LOL
I'm guessing that we shouldn't use bleach solution on any split tomatoes?
