|My neighbor grows tomatoes in containers in her enclosed patio. She has great success with cherry tomatoes, but the larger varieties are watery. What is she doing wrong?
|Sounds like a cultural problem, similar to soft-rot. If there are no wounds or insect tunnels, and no visible mold on the fruit, I expect that the tomatoes are being overwatered. Soft-rot occurs in fields of tomatoes subjected to heavy rains. In the containers, allow the top inch of soil to really dry out before applying water to the tomatoes. Toward the end of the season withhold even more water to force the plants to ripen the fruit. (In commercial fields tomato plants are not watered after mid-August.)
