Why Do My Tomatoes Develop Large Cracks On The Skin?

Question

All of my tomatoes develop big cracks on the outside skin as they are getting ripe. I water them twice a day. What am I doing wrong?

Answer 1

It's usually a watering and temperature issue. Mulching the plants well and watering deeply once or twice a week should help. If your tomatoes are in containers you need more frequent watering, but once a day should be ample. These articles should help:
