Title: Yellowing leaves on non-native globe willow in Las Cruces, NM
Answered by: Barbara Medford

QUESTION:

I live in Las Cruces, NM. I have a good size globe willow tree. The leaves are turning yellow and brown dryness at tips and leaves are falling off. Does it just need water?

ANSWER:

The Lady Bird Johnson Wildflower Center is dedicated to the growth, protection and propagation of plants native not only to North America, but to the area in which they are being grown. 

 

Salix matsudana, globe willow, is a native of eastern Asia, and therefore out of or range of expertise. Willows generally are fairly weak, short-lived trees, susceptible to many insects and diseases, as well as dropping a lot of litter. The globe willow is often infected with slime flux, a bacterial disease that is soil-borne. They are frequently found in the Rocky Mountain area, in warm valleys, so while they are not native to North America, they are at least well adapted to the area in which you live. You are in USDA Hardiness Zone 8, so your willow can probably survive, but we would certainly do supplemental watering when the weather is hot and dry. 

For more close to home advice, contact the New Mexico State University Extension Office for Dona Ana County.
