Much of the change in a tomato's flavor through a season has to due with Brix or sugar content driven by sunlight and heat. I've tasted the same phenomenon as Catherine Vinson described. As far as my tomato plants' size and fruit size, much of that is due to the use of mycorrhizal fungi and well developed organic soil, at least it was in Texas. I grew a Striped German in a 10-gallon container that took the biggest tomato at Dan Loep's Harris County tomato contest at Covington Gardens. The fruit was 29 ounces. I can't believe how much more productive everything is here in Illinois. My garden soil is much worse than what I left behind in Texas--little organic content, globs of black clay. But with mycorrhizae, a thick layer of straw and the wonderful climate, the plants are climbing to the sky. Does anyone have a good way to add support to 10 ft. tomato plants that are trellised on Gardener's Supply's tomato ladders? I've been using string to tie up the errant suckers, but the height has become a real problem.
