| Several of my twisted juniper (Hollywood Juniper) plants are turning from green to brown. My area is high desert with temperatures in the 90's to 100's. They have been planted several years, are on automatic drip watering systems, and the soil is sandy. I found only one dead beetle on one plant and no other signs of insects. Thanks For Your Help Terry Adams |
| Juniper can develop a fungal disease called twig-blight, and a root rot if soil doesn't drain well or is kept overly wet. Root rot is a more common problem, but you may be dealing with twig-blight. Phomopsis is the fungus, and with a magnifying glass you should be able to see tiny black fruiting bodies on infected leaves and stems. Infected stems do not die back to the soil line, as they will if root rot is involved. Probably the best course of action at this point is for you to take a sample of the problem to your local Cooperative Extension office. Knowledgeable folks there can diagnose the problem and suggest control measures. Phone 323-838-8330. Good luck with your plants! |
