Rings on underside of Tomatoes

Question

I have a container garden of tomatoes and all summer long the tomatoes have had this ring around the bottom. We did have an insect problem, but Sevin took care of that. I have to cut off a good 1/4 of the tomatoes when I use them as this is hard and “pithy”. I do have a picture I could send if it will help. Thanks for your help.

Answer 1

These are called concentric rings on tomatoes and are normally the result of environmental changes that are water related. They are similar to tomato cracking. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-cracking.htm
