To much or to little?

Why are lower leaves on tomatoes plants turning yellow. If I water less the so. Ca. Heat kills them.

Probably early blight. Does the yellowing start at the bottom and slowly works its way up the plant? If so it has nothing to do with the amount of water. It is a soil fungus that is spread by water splashing soil on the leaves and by leaves touching the soil. You can really slow it down by sprinkling whole ground cornmeal all around the plant before the yellowing begins.

The bottom leaves were pruned shortly after planting. Very careful when watering and plant is about 3'.

Lower leaves were trimmed shortly after planting and very careful when watering. Plant is 3' and blooms dry up and fall off.

If blooms dry and fall off it is because the nighttime LOW temperatures are not correct. I too have early blight problems but I remove ALL of the limbs, not the suckers, from the plant up to about 1 foot. I can just about guarantee you that early blight is causing the yellowing and the reason for bloom drop is either too warm or too cool for fruit setting. Early blight usually does not affect fruit set. The OPTIMUM temperature for tomato fruit set is about 64F - to about 70F NIGHT TIME LOW TEMPERATURES. Anything above or below these temps will cause blossom drop, except for cherry type tomatoes.

Sounds like You are on to something Chuck. Thanks for the advice. The nights are getting warmer now so that should help. Can I remove yellow limbs?

Yes, you can remove the yellow stuff. Get it out of your garden

Time to clean shears and get to it. Thanks again.

Make sure you clean your shears after doing this with alcohol or bleach or something similar or the next time you cut something you will spread the fungal spores.

Good advice.
