One of my plants has a few minorly catfaced tomatoes. Just the area around the blossom end is affected, about 1/4" in diameter. I don't intend to remove these from the plant as they should be edible as long as I cut that end off.
At what point do you know if the tomatoes have a catface problem? Can you tell very early on, and if so, how severe the catface damage will be? What should you do if the catfacing is or will be severe? Should you remove the tomatoes early so the plant can use its resources elsewhere?
