Title: Disease in non-native pittisporum in Central Texas
Answered by: Barbara Medford

QUESTION:

Is there a disease in central Texas (Round Rock) affecting dwarf pittosporum? Specifically, clusters of dead leaves and much leaf drop. Some white, cottony residue on wood but not sure if it is mealybug. Spreading to all pittosporum in my landscape. I have seen similar looking plants in town.

ANSWER:

Pittosporum is native to China and Japan, and therefore out of our range of expertise at the Lady Bird Johnson Wildflower Center. We encourage the usage of plants native to the area in which they are being grown because they are adapted to the soil, water, and environment. We did a little research and found that, indeed, pittosporum is vulnerable to aphids, cottony cushion scale and mealy bugs, which the site we were looking at said could be treated with horticultural oils. We neither recommend for nor against the use of pesticides, and are not familiar with their uses, especially on non-native plants. Therefore, we suggest you contact the Texas A&M AgriLIFE Extension Service of Williamson County for more specific information on what is going on in your area. Contact information and further links to that site are on their home page.
