Probably as big a problem is that most varieties will not ripen unless the night-time temperature is below about 70F. I ran into that problem one year when all of August was above 80F and I had huge quantities of huge green tomatoes accumulate and then ripen simultaneously after we got a few cool nights. I got about ten bushels in one picking. Nowadays I just use the farmers markets where I can buy a 1/2 bushel basket for $10 - $12 and 13 ears of corn for $3. Tim in Amish country.
