Q

I planted my tomatoes last Thursday, May 22. It was just before all this rain and colder air came in. Now all the plants leaves are turning yellow/cream color, except for the veins are staying green. Some neighbors said they might have had too much water, I have never had tomatoes do this before.

Answer(s)

A

The bleached foliage on your vegetables maybe a result of cold weather.  Cold injury is successively worse with cooler temperatues and/or longer exposure.  Some of the most susceptible plants (peppers, cucumbers, squash, etc.) can become permanently affected, not dying, but growing more slowly than those not affected. Your pale leaves, could also have been the result of overwatering or a combination of the two.

As the weather warms, your vegetables should send out new sets of greener leaves.  Make sure that you don't over-water them.  The yellow leaves at the bottom of the plant will probably drop off.
