Bittersweet, haha! I never proclaimed to be a math wizzard! It doesn't sound so bad that way.
I've had gardens down here that produced a lot and ones that did absolutely nothing. It is way more difficult here than up north. In Pennsylvania I always had vegetables for the whole year. And I sold a bunch of them too.
We have nematodes in the ground that attack the roots, especially of tomatoes and lots and lots of bugs. I have a family of raccoons who live in a nearby empty wooded area.
We'll see how these plants do. So far the tomatoes I put in haven't perked up yet. Their root ball was practically non-existant and their roots didn't hold onto the soil when I took them out of the little containers. Even watering hasn't helped yet. Maybe when it gets warmer?
It's too bad you didn't put your perennials into pots for later when the workers were done. But maybe they were too big?
