When we got back home form our trip, I was pleasantly surprised to see my tomato plants had taken off. They're growing much better than expected!
When you look at the grid below, count 1-4 in the first row, 5-8 in the second, etc. until you get to 16 in the bottom right corner. My tomatoes are in square 7 and 10. When we left, they looked smaller than squares 6 or 11. And look at them now!
