The Q&A Archives: Tomato plants turning yellow

Question: The leaves on my tomato plants are turning yellow. They are blooming but I need to what to do.

Answer: The lower leaves on tomato plants naturally turn yellow and die off during the season. If the yellowing is on all the leaves, you are overwatering. Tomatoes like a consistent moisture level in the soil, but too much water can actually suffocate the roots. So, try watering less frequently, allowing the top half inch of soil to dry out between waterings. You should see an improvement when you water less frequently. Best wishes with your tomato plants!
