Stressed Plants

What is destroying my Skip Laurels (planted on the North side of the house) and my Crape Myrtle ( on the East side)?

This time of year many woody ornamentals are looking stressed due to drought and possible fungal issues, etc. No controls are recommended as it is late in the season and there should be enough carbohydrates stored in the root system to put out new growth next season. Water during dry periods and make sure mulch is no thicker than several inches and away from the base of the trunks.

Cherry laurel - looks like the foliage has been subject to cherry shot hole, a fungal disease and some minor insect feeding like possible weevils. The leaves have a shot hole pattern that looks like it was caused by an insect. However, this is a foliar fungal disease favored by wet weather. The infected leaf tissue falls out and the holes are left behind. The damage is cosmetic and no chemical controls are recommended. Rake up any fallen foliage. The plant will recover.

If you notice additional symptoms, send us photos so we can see what you are dealing with.

Crape myrtle - possible leaf spot. No control as it is late in the season. Rake up any fallen foliage and discard. Next season as soon as you notice symptoms send us photos so we can see what you are dealing with.
