Tomatoe Plants

Asked August 26, 2017, 11:24 AM EDT

Our tomatoes appear ripe on the outside but are very hard. When you cut them the insides are very firm and not ripe. They are unfit to eat. This is the first year we have had this problem. We purchase the plants the same place every year. They are Better Boy or Early Girl variety. I think we got a batch of bad plants.

We would be interested in seeing a photo of the condition you describe in your tomatoes, if you wouldn't might sending one. The firm internal flesh can be due to low potassium levels relative to nitrogen. It could also be due to environmental stress such as high heat and/or water stress, or other factors. Any tomato varieties can be susceptible to this problem. In the future, we would recommend side-dressing the plants when they first start fruiting. Use equal parts nitrogen and potassium.
