Leaves on my flowering cherry tree are turning brown

Q: The leaves on my flowering cherry tree are turning brown on the tips and the it is not as green as it was earlier this year, I sprayed it with a fungicide but it did not help, what can I do?

A: First let me say that this is not a plant that I recommend for this part of Texas, it grows better in areas with colder winters and milder summers. That said what you are describing is more likely heat or drought stress. Any time the browning begins on the tip of the leaf and works its way down that is stress from lack of water, heat or chemicals in the water or lack of tolerance for the alkaline soils. Be sure to keep it well watered in the summer, depending on how fast your soil drains it may need a good soaking with water 2 or 3 times a week in summer, mulch around the roots to help keep them as cool as possible and feed with a basic water soluble plant food or an organic product such as liquid seaweed and fish emulsion. It may also benefit from some form of iron or soil acidification treatment.
