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.

- Is it good to cut the lawn shorter right before winter? I normally cut my lawn quite high, but it seems like I heard that it is good to cut it shorter for winter. Thanks.
- My backyard has far too much grass. I'd like to turn a fairly large portion of the lawn into waterwise beds and also expand my backyard vegetable garden. Two years ago, I made some beds by removing the turf. However, it is not only very hard work but it also results in a large amount of excess sod, and takes a good amount of topsoil with it. It also seems wasteful to send it to a landfill. Is there a way to kill the grass without herbicides? For example, will covering it with black plastic be an effective way to kill the grass? If so, how long will it be before I can plant in the new beds?
- Will kumquat trees grow in St. George, Utah?
- I recently had a handyman come to adjust the sprinklers at a house we do not live in and are trying to sell, and he unfortunately turned off the sprinklers without us knowing, and the grass went a few weeks without being watered. Since we discovered it, we began watering and I laid down turf builder to see if I could jump start the regrowth. The grass looks brown and dead over much of the lawn, however, since I fertilized, I can see little green spots and individual green shafts here and there. What should I do now? Can I seed over the existing dead lawn? What is the fastest and best way back to green without tearing up the whole yard and starting again? (The backyard sod was new last year)
- I have a young (~3 year old) brown turkey fig. I planted it last fall and it survived! the winter. It is producing small figs now but the leaves have a brownish gray powdery looking substance on them. It doesn't rub off but looks like powdery spots. Any clue what it might be or what I should do? The leaves remain green and look healthy. This appeared after the recent heavy rains.
- Where can I get a chart that tells me when to plant vegetable or plants and also can you tell me how to plant blackberry and raspberry plants?
- What is the best thing to do with seedlings that are too tall for the seed starting kits? I have cauliflower and tomato plants that are 'leggy' and now too tall, but not yet ready to go outside. I received last week an advertisement about that hybrid zoysia grass that needs little watering and little mowing. Is that for real and if so, would it work in our climate? Supposedly it is cold hardy to -30. If I think that I there are gophers in my yard, what is the best way to eradicate them?
- I planted a spanish fir in my yard just two weeks ago. It appears to be dying. How often should I be watering it? And how much water should I be giving it each time that I water?
