Since we're at the end of the month, let's do a comparison to last year's May totals.
The first tomato picked last May was on May 2 while this year the first tomato picked was on May 16. Last year the first tomato picked was SunGold, which also turned out to be the most productive. This year the first tomato picked was Red Currant, which looks like it will be the most productive.
I'd say that most of these differences are negligible with the exception of the last paragraph. This year's crop “feels” like it's about two weeks behind last year's crop. That may not prove to be true in the long run, but we'll see.
Last year, the highest harvest total occurred in mid-July (July 13 and 14, to be exact). In 2006, the heaviest harvest dates were in early July. This year, I'll estimate the heaviest harvest date will be around July 22 or 23 based on what we know so far.
All the plants look healthy, some better than others, but all appear healthy.
