Roma Tomato Brown Rot

Question

I’m growing roma tomatoes. In the last week I noticed a brownish section at the bottom of some of the unripened fruit. Is it a disease or a result of watering in the evening vs. morning watering?

Answer 1

That is blossom end rot. It is actually a nutrient deficiency that is normally brought on from rapid growth on the plant or too much water. This article will tell you more about it and how to deal with it: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-blossom-rot.htm
