Leaves Drying and Falling Off

I have several crepe myrtle bushes and one tree. The tree is blooming beautifully with deep green leaves. The bushes are only blooming partially and the leaves are turning yellow and falling off. It has been VERY hot with little or no rain, but we do have a sprinkler system that runs several times a week. Do not see any bugs. Can it be the heat that is bothering them? The tree is next to the house and better protected.

Yes, it is likely heat/drought stress. It would be better to water the plants via a soaker hose or drip irrigation rather than a sprinkler system, as the latter will not penetrate the ground like the other two methods. In fact, more water is actually lost through evaporation and/or run-off with overhead sprinklers. If you can up the water, this should help.

Why Crepe Myrtle Leaves Turning Yellow?

Newly planted crepe myrtle is flowering but lower leaves are turning yellow. Is this due to water needed or too much water? Or is it typical of this time of year?

Your tree is probably just experiencing shock from planting and is normal. Newly planted trees need lots of water for the roots to establish. These articles should help: http://www.gardeningknowhow.com/ornamental/trees/tgen/watering-newly-planted-tree.htm

Our Crepe Myrtle Bark Is Whitish Spots, Losing Leaves and Dropping Sap.

For 15+ years, our two crepe myrtles by the driveway have been just gorgeous, but a couple of months ago, I noticed some whitish spots all over the bark. Then, we began noticing the stickiness on the driveway. The leaves are few and it looks like BOTH trees are dying. I don’t notice the whitish spots as much now. We live in DFW, Texas, so it IS hot! We would certainly appreciate ANY ideas as to what you think might be wrong with them.

It sounds like you have aphids. Treat the tree with a pesticide. I personally like neem oil because it is systemic, so you don't have to get every nook and cranny of the tree for it to kill all the aphids on the tree.

Crepe Myrtle Leaves

The leaves on our crepe myrtle is turning light green and yellow. It is not blooming either. The other two trees in the same area seem okay for now. What do we need to do to save this tree?

ANSWERS

The tree may be suffering from an iron deficiency. This normally happens either when the plant is watered too much and the nutrients get leeched away or if the pH is too high. Test the soil and correct and nutrient and pH issues found when testing. Also, make sure that the soil is not too porous and is letting the water run away too quickly.
