Title: Problems with Juniperus ashei in San Antonio
Answered by: Barbara Medford

QUESTION:

I live in San Antonio and have many juniper trees. On inspection I do not see insects or any other form of damage, but my trees are turning brown and dying. I have already had to cut one down. When I look around my area I notice other Juniper trees that look the same. Please tell me what is going on and how can I save my trees?

ANSWER:

We are getting all kinds of correspondence from all over, not just Central Texas, about browning or even yellowing of the foliage of various members of the Juniperus genus, including Juniperus ashei (Ashe juniper).

Please read this previous Mr. Smarty Plants answer, which has all sorts of suggestions about the cause. We have even been in e-mail correspondence with a number of area forestry experts or landowners with lots of "cedars." Our opinion is that the extreme drought this year has so stressed the junipers that they have become susceptible to mites of various kinds, including the juniper mite. The consensus from all this discussion is that until it rains, the problem is going to persist. We realize that is not much help to you, but the Ashe juniper is a persistent tough native tree, we know it has had problems in the past, but we think, as a species, it will be all right. There will probably be some tree loss, as we are now passing out of May, our traditionally rainy season, but that is always a risk in gardening in what is basically an arid locale. This makes conservation all the more important, and planting trees and other plants that can tolerate low water use, as well as cutting down on thirsty non-native lawns.
