In some cases, the cause of tomato plants turning yellow and dying can be 100 percent normal.
Why would a tomato plant suddenly start dying in the middle of summer? Because it could be a decisive tomato!
Tomato is either determinate, or indeterminate. Indeterminate tomatoes will grow and produce until a frost or freeze occurs.
But certain tomato varieties have a specific lifespan. They produce their entire crop within three to four weeks and then die quickly.
A great example is the Roma tomato. The Roma tomato is quite popular among home gardeners.
