Tomato plants dying
I have four tomato plants in a 2 sq.yd. container on the third floor balcony of my apartment complex in Minnesota. The container is partially shaded so the plants receive around 6 hours of sunlight each day. In the past week, I've gone from four healthy plants to three plants that are all but dead, and the fourth one - which has always been the biggest - is showing stunting in the new growth, as seen in the attached photo. Additional symptoms: I noticed one of the dead plants had no roots left when I pulled it - they were completely absent; and before each plant died, they started leaning badly, as if wind sheared. Is it possible that I am overwatering or perhaps overfertilized the plants? I initially suspected herbicide damage but don't see how it could have drifted up to the third floor. Perhaps some kind of wilt or rot? Is there anything I can do to save my remaining plant?
I'm sorry your tomato plants aren't doing well! This sounds like a classic case of root rot, usually caused by overwatering. You can possibly save your last plant by following the steps in this article:
