Jeez- I'm sorry about the squirrels vandalizing your tomatoes, Poppy. I can't speak for you, but I think I would rather they just eat a whole tomato or two or three than just damage several. Something similar appeared to be happening to my peaches a month ago, but they've been safe lately.
I wish I had started some marigolds this year. I save seeds each year and I'm sure the seeds are still good, but I just didn't get around to starting any. I don't know if they keep pests away, but they add some color to my garden.
