Because of a cold wet spring, the tomatoes are just now coming in.

In many of them, the flesh around the stem is yellow/green and hard.
The online plant problem Web sites say this is due to too much sun and
that the remedy is to shade the plants.

However, our neighbor's maples have grown in to the point where we're
only getting 2 to 3 hours of direct sun per day, so I have a hard time
believing that's the problem.

On the other hand, the plants are in a corner formed by two exterior
walls of the house which is like a little solar oven; it gets pretty
warm in there during the period we do get sun.

Could the problem be heat, and not light?

Any other avenues to investigate?
