My front yard has large patches of dead grass. Originally I thought it might be a result of grubs, but dug down and didn't see any larvae or grub worms. The condition is worsening and now I've noticed pencil-eraser size holes throughout the dry areas. Do you know what this is and how to prevent or stop it?

I suspect the holes you see in the dry areas may be made by emerging lawn pests, such as billbug, but I'm not sure. The holes may also be from bird beaks as they forage for insects (yay, birds!) Here are some hints on how to scout and diagnose for billbugs and other lawn pests: Dig up a 6 by 6 inch square of your turfgrass, including 2 inches of soil, put it in a bucket and pull it apart, looking for any insects or larvae. Collect any/all you find. Identify the insects by referring to these USU Extension Fact Sheets:
White grubs, at
Sod webworm, at
Cranberry girdler, at
There's only one generation of billbug per year, they may be emerging as adults about now. Most of the damage is already done for the year, so if you don't find any pests in the turf sample, wait until next May to treat for the pests. Once summer cools off (highs in the 80's), you should fertilize the affected areas to promote new growth and vigor, to repair the damage. Also, be sure to check the thickness of the thatch layer in your turf. If it's thicker than one-half inch, plan to have your lawn core aerated in early fall. Aeration helps promote thatch decomposition. Thatch is a protective habitat for the billbug, so it's best to minimize it.

Could you give me a recommendation on what to do to cut down on the weeds? Should I switch to a different company or do you recommend fertilizing myself? Thanks, Ryan

- I have 2 cottonless cottonwoods in my back yard. They are both about 7 years old. I noticed this spring that the trees have really grown tall but on the main limbs in the middle of the trees there are no limbs coming from them. I also find little pieces of new branches all over my lawn like they have come off right at the base where they connect to the tree. There are also at those points little scabs of some kind right where the branch has broken off. What is wrong and can I save these trees? I grew this kind of tree because they are fast growing trees and I wanted to enjoy some shade while I was still around to enjoy it. I am so afraid that there is something seriously wrong and those years will be lost. Can you help me with the info I have given you? I would appreciate it so much if you have an idea of what is wrong and what I can do to fix it.
