Lack of water causes established trees to die back

Q: Around town and in my neighborhood, many midlife trees are dying. In beautiful large trees, there are dead branches and sometimes just a fully dead tree. Some trees are planted in gravel and some in a yard. Do you notice that also?

Aphids are a huge problem because they reproduce rapidly

Q: I have a small crape myrtle tree with leaves that were constantly wet this year. The ground and plants underneath were always wet. Now that the leaves are gone. I can see the branches are also wet. Another tree I have is perfectly dry and normal. What’s causing this and how can I correct it?

Some trees will grow back after being cut near to ground

I have fruit tree pruning classes at 1 p.m. Fridays and 9 a.m. Saturdays during the month of December at Ahern Orchard in downtown Las Vegas. Class size is limited so you must enroll on Eventbrite or contact me.
