We have some leaves on certain tomato plants turning yellow (7 plants out of 12 planted). Two plants producing blossom end rot. We want to cut off the affected leaves on mostly healthy plants. Should we pull out the plants giving us blossom end rot?

Some reasons for tomato leaf yellowing can include overwatering or underwatering. Also, it is normal for bottom leaves to yellow and drop as the plant ages. You can remove the yellow leaves. See our vegetable profile for cultural information on tomatoes http://extension.umd.edu/learn/vegetable-profiles-tomatoes

Blossom end rot - Promptly remove any fruits that have blossom-end rot or are badly malformed. This nutritional disorder is caused by a lack of calcium in developing fruits and is brought on by dry conditions and inconsistent watering. Water your plants deeply and regularly and keep them mulched. Tomato plants may need 1-2 gallons of water each at least twice a week during droughty periods. Plants tend to grow out of the problem.
