Q.tomato branches are drying out and dying
Planted tomatoes last week but now lower branches of the plant are drying out and dying. What am I doing wrong? First four days after transplanting seedlings, the weather was cold and windy. Peppers planted right next to the tomatoes in the same raised bed look absolutely fine.
The first days can be tough on those young plants. Wind can dry out the leaves, which may be the cause of the stress.
Water the plants well, tomatoes are thirsty plants. As they become established and grow you can snip off the damaged leaves.
Here are a couple of links for you with more information.
