I have a large mature cherry tree that over the past 3 weeks has had its leaves turn from green to yellow and now die off (July). I have not changed any watering patterns. The trunk "crotch" has debris, and small crawly wormy insects. How can I treat? Is it too late? It's a lovely tree, provides great shade and privacy.

It's difficult to diagnose the problem with your cherry tree and the wormy insects may or may not have anything to do with the leaves yellowing and falling off. As far as treating, first have to make a proper diagnosis. We will have Master Gardeners on Monday August 25 from 1 pm to 4pm at 2001 South State Rm S1008 hold a plant problem diagnostic clinic who may be able to identify the insects if you bring in a fresh sample. Also further questioning by Master Gardeners about other conditions may help figure out what the problem is.
If you can't make the clinic, you can send sample directly to the Utah Plant Pest Diagnostic Laboratory. Follow this link http://utahpests.usu.edu/uppdl/htm/forms to find out more information on submitting samples for proper diagnosis.

- I have some fruit trees in a lawn area that I have been fertilizing with ammonium sulfate, but needed to change to a weed & feed. Is the fruit still safe to eat?
- I am going to overseed my west lawn. Do I need some type of covering (straw, peat, etc.) to help keep the seeds in place?
- Do you have the names of companies or individuals who spray fruit trees in the spring and summer to prevent bugs and disease?
- The leaves of our sweet cherry tree have yellowed and our falling off at an alarming rate. This started two weeks ago and in another week ALL the leaves will have dropped except for a few on the tips of new growth (i.e. water spouts). This happened last year to two of our other sweet cherry trees. They did NOT come back this spring. Dead! The trees are 25 years old and pruned yearly. I've been fairly diligent about spraying (dormant oil, fruit fly, and borer) for the six years I've owned the house. At times they have shown signs of borer (or other insect) damage since there has been gumming spots on the trees. When I bought the house I removed the grass around the trees (not quite to the drip line,but a about four feet from the trunk. The trees get water from the lawn sprinklers, but I regularly (every 2-3 weeks) let a hose run water around the tree and soak in for a couple hours. When I fertilize the garden (commercial IFA garden chemical fertilizer)I toss a couple handfuls at the base of each tree. So some fertilizer about twice a year. The soil around the house is mixed. I would guess that most of it is moderate clay. We live on the edge of the bench not far from the mouth of Hobble Creek Canyon. If I had just walked into the yard, I would guess that the trees were getting too much water (yellowing leaves) instead of not enough water (dry crisping leaves). But I really don't water the trees that much and not at all in the last couple weeks when this yellow & leaf drop started. My only other clue is some leaves have brown spots. About the time we bought the house, a neighbor had a cherry tree drop most of its leaves and they were told (USU ext?) that it was a fungus; they sprayed and saved the tree. They've moved so I can't ask them specifics. I don't remember if the leaves had yellowed and then dropped. Too long ago. Help?
- Why do we rake leaves? What would happen to my lawn and flower garden if I just left them on the ground and let the grass and perennials grow up through them? We currently mulch them with a mower and let most of them stay. Are we raising the elevation of our lawn? Are we doing good or bad to it?
- Last year when I was about to harvest my corn from my yard I found that something got to about half of it before I did. I don't think it was insect because of the nature of the damage; I suspect birds. On the ears in question the husks were literally shredded and each kernel picked out. I know there are blue jays nesting in the area but this was the first time any thing like that happened. I don't think it was a mammal since the stalks were intact and not collapsed from the weight of what got at the ears that were devoured. Do you what causd this to happen? Is there something I can do to prevent that from happening this year? Thanks
- I have a mature elm in my backyard that was probably planted when the house was built in the 70's. We bought it 3 years ago and I have noticed that something is eating away at the bark. There is a reddish-brown streak (almost like what you would see in a human that has blood poisoning) that runs up the bark. I cut off one of the lower limbs that the problem had progressed to. The bark is very "mushy" and looks decayed. Chunks of bark fall off at the affected areas. I cannot see any bugs that may be causing this but I suspect that is the cause. This tree has 2 main branches that extend from the bottom and this is where the main damage seems to be. I am concerned that the tree could "split" at this point if it becomes weakened. I need to know the cause and treatment.
- I have a red photina thats leaves, in part of the bush, seemed like they were burnt. Is it a disease that these bushes can get? If I cut it back all the way, will all of the bush come out of it or should I get rid of the bush? The photina next to it is just fine.
