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.

- We live in Perry, Utah. We are getting our yard prepared for sprinklers and grass. We are doing a lot of rock in areas, so we are not watering as much grass etc. We are wondering about the grass itself. At this point we would like to put sod down, but we are wondering what type of grass we should be looking for that is heat and drought tolerant and that will do well all year long in the area where we live. Can you suggest a particular sod or seed, and a place to obtain it, that might work well for us?

- I have a scarlett red maple. It's about 8 years old and last year the leaves didn't get very big. This year, it hasn't even began to bloom yet although, It has tiny buds. I noticed that the bark in some places peels off very easily. Under the bark, it looks like there may be some black flecks (maybe bug feces). I only noticed one little red colored bug under where I peeled the bark. I don't see any other bugs anywhere, even at the base. Do you think it could have a disease or bugs? I am going to put some fertilizer steaks around it and pour some Bayer Advanced tree and shrub insect control around the base of the tree. Is it too late to spary it?
