I have a healthy looking aspen tree whose leaves turn brown and fall off in early September without ever turning colors. I live in Midway and Aspens do well here. Do you know the cause and can it be corrected?

Do you notice any leaf spots or "weeping" holes on the trunk? Are the leaves on the tree very dark brown/almost black?
How old is the tree? Aspens typically live about 15-25 years in the landscape. (In nature, succors are constantly springing up to replace older trees.)
The easiest way for me to diagnose the problem is if you send clear digital pictures of the leaves, any holes or drainage spots on the trunk, whole tree, and any other distinguishing characteristics.
Here is a good link about aspen trees from Colorado State University. http://www.ext.colostate.edu/Ptlk/1701.html

- 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?
- 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?
- I have mexican fruit flies that lay eggs and hatch larve in my apples and cherries. They are larger than reqular fruit flies and have black and white striped wings. When should I spray? What should I spray with?
- We would like to plant a pasture (about 2 acres). We would like one that creates sod, like a lawn, rather than a bunch grass. It will be used to hold a hillside and eventually to graze a few animals. We could cut it for grass hay also. What would be the best varieties of seed to use for a pasture like this?
- 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?
- We moved into our 2-story home in Lehi 1 year ago. The tree out front (which I planned to have my husband cut donw) has doubled in height since then. I don't know what kind of tree it is...medium size, darkish leaves. How do we (and when should we) cut it down to prevent it from sending up suckers?
- We live in a suburb near the mountains and have a lot of deer wandering through our neighborhood eating our flowers and vegetable gardens. They are not afraid of people and walk through our backyard any time of day. What can we spray on the garden plants to stop them from eating them?
