Q: You mentioned controlling borers with chemicals, but can borers in trees be controlled without using chemicals?
Two major problems occurred to landscape plants and fruit trees these past few weeks during the summer. First was the heat. They were stressed. High temperatures seemed to linger longer than normal. In addition, minimum nighttime temperatures stayed elevated well into the 90s for more days than I remember in the past.
Recyclables are not the kind of trash that’s taken to the dump. Instead, these are materials that can be returned to their original, raw form before shipment to other facilities to be recycled into usable resources.
Q: I have a Mexican bird of paradise that was planted five years ago that suddenly died. It had flourished until now. I pulled out the plant and sent you some pictures of the dead plant, girdling or circling roots and borers that I found in the center of the stem that probably killed it.
Henderson may not be Vegas bright or Sedona red, but Nevada’s No. 2 city makes up for that with a sense of community that supports fitness goals, artistic endeavors and adventure seeking.
Q: I have two paloverde trees in front of my house. One seems to be fine while the other has struggled for four years. I am told the tree is healthy, but every summer it leaks white, sticky foam from the trunk. This foam attracts bees and beetles. The tree has received professional borer treatments twice a year, but it’s still bad.
This is the time of year when borer damage in trees and shrubs is most obvious. Limbs are dying. Their damage can be seen from a distance now, but they’ve been working hard feeding on the inside of trees and shrubs for months.
Q: In my morning walk around the garden, I found an unusual pattern on the leaves of my Arabian jasmine. Do you have any thoughts on what might have caused this?
Q: The leaves on my fig tree appear burned after this rain. I foliar sprayed it with neem oil and soap and fish protein isolate. These trees were planted last fall and mulched with 1 foot of woodchips and looked amazing until now. They are watered three times each week in the summer.
Q: We’ve noticed leaf damage this year on our rose bushes and apple and pear trees. More than previous years. But, peach, apricot and pomegranate seem unaffected. Some of our roses were decimated. Any idea what pest causes this and how to control it?
