When the temperature gets warm enough, regardless of month or our readiness, bugs and fungus wake up. First is Pinon Needle Scale, a moisture sucking bug presenting as little black dots on the inner needles of your Pinon tree. They like cool, not cold or hot, weather. They are VERY active in February and March. By April, it is too warm for them. They nest on your trees in a white cotton or dryer lint type mass. You see that on the undergrowth and the crotches of the tree (wherever the rain does not hit). If you see little black dots, it isn’t the end of the world. This bug is not a killer, it just thins out your tree as it kills the inner growth before the growth would naturally fall off. I like to say that it is okay to have the scale come to your tree. They are bugs and we need them for the circle of life. It is NOT okay for them to invite friends and family and throw a rager at the expense of your tree. What should you do?
• The easiest control is to simply hose off the dryer lint with a hard spray of water. This should be done about every 2 weeks in February and March.
•
Dormant Oil* acts as a suffocant and can be used as often as you want. Once we get into April, you are wasting your time and energy with dormant oil for this bug.
• Chemical treatment can be used, but chemical for a bug as benign as scale is a gateway drug for killing all bugs in your yard. We need bugs so we can have lizards, and roadrunners, and somewhere down the line we get to eat chicken.
You will NEVER get rid of this bug. You can only control it. It travels in the wind. It is also worse in areas where Pinons are in abundance in the neighborhood. It’s like trying to keep your child healthy in daycare.
Fungus requires cool and moist conditions to grow. We rarely have these conditions but when we do, it is in March and during our monsoon for a day or two. That’s all it takes for fungus to grow. We see fungus on Euonymus, Boxwoods, Photinia, Roses, and Blue Spruce primarily, especially those on the north side of the house.
You can mitigate this issue by trimming up your shrubs and Blue Spruce, so they are at least a foot off the ground. Shrubs and trees that touch the ground have the tendency to trap moisture, thus creating a habitat for fungus. Clean up all leaves under the shrubs so as not to trap moisture or spread an existing fungus. You can also spray Dormant Oil on your shrubs,
not on the Spruce. Oil discolors them.
Finally,
we are currently scheduling for treatments in March and April. If we already have a proposal on file for you, simply call the office and I will get you scheduled. If we do not, call the office for a consultation. We are still short staffed in our Spray Division. All treatments will be scheduled on a first-come-first-served basis.
*My Dormant Oil Recipe
In a one-gallon sprayer of water, add
• 1 cup vegetable oil
• 1 teaspoon dish soap
Spraying should be done when temperatures are above 40° (below this temperature oil gels) and below 80° (above this temperature oil fries).
Thank you for your ongoing patronage.
We are a family-owned business whose clients are like family to us.
