I have 2 red tipped photinas in my front yard against the house (south facing). They were great for the first 3 years, but now, for the last 2 winters the leaves have dried out and dropped in the spring. I thought it was a lack of water over the winter, so I tried to help out, but that didnt help. Should I prune them back in the fall or is there anything I can do to help them so this doesn't happen next winter?

Many things can cause the symptoms you describe. I'm not sure where in Utah you live, but red-tipped photinias, with a cold hardiness rating of zone 6, are only marginally cold-hardy along the Wasatch Front. (Salt Lake is zone 5 -- annual minimum temperatures lower than zone 6). Our last two winters were colder than normal, so the low temperatures may have damaged the broadleaf evergreen leaves of your plants.
Red-tip photinias are also susceptible to a number of diseases, including leaf spot and fireblight. You should take samples of leaves with and without symptoms to your local county Extension office where they may be able to help diagnose your problem, or they may instruct you how to send your samples to the Utah Plant Pest Diagnostic Lab on the campus of Utah State University.

- I have been told by a tree care company that my ash trees are infected with bores. They can be treated, and the trees should survive. Though my internet research I found ample information on emerald ash bore, however, that the research was largely on trees in Michigan. Would I have emerald ash bores, or do another type of bore exist in Utah? The tree care company suggested treatment in the spring, and another in the summer. Does that sound appropriate?

- I live out on the western edge of South Jordan. The home I just bought has very sandy/rocky soil. The lawn is an inch to inch and one half depth. I have decided to add at least four inches of topsoil to my back yard this fall and re-seed. The front yard is still worth saving. I have three questions. What is the best Ph level for my soil in this area and what type of seed will work best in high sun location such as the one I live in and last should I consider some type of organic treatment to my front yard to strengthen it and promote growth?
