I planted two Japanese Skimmia (one male, one female) in my backyard, about 4-5 ft from each other, last summer. Although the female is thriving, the leaves of the male plant began turning yellow several wks ago. Now, the plant has lots 4/5 of its foliage.
What may be causing this, and what treatments should I follow?
|Based on your description I am not certain what is happening to your plant. Since one is fine, your care must be good. It might be a problem with poor rooting, such as a large rock underground or encircling roots, it might be a problem with a disease such as verticillium wilt, or it might be something else such as accidental herbicide damage or a blockage in the watering system (if you use one.) Since the problem began just as the heat of summer picked up I would suspect a root problem, but it is impossible to diagnose this kind of symptom long distance. I would suggest you work with your county extension and/or professional certified nurseryman to obtain a specific diagnosis of the problem and then work from there. I hope it can be saved, losing so much foliage is a sign of a serious problem.|
