You didn't say where you live, but the Mexican fruit fly would be a rarity if ever found here in Utah. It normally is in Central America, Mexico, Southern Texas and southern Florida.. It can be identified by the long ovipositor on the female. Look on Google images to see one. The Western Cherry fruit fly is common around here and lays eggs on the cherries when they turn straw yellow. They also have bands on the wings. They don't, however, lay eggs on the apples. The wormy apples are caused by a coddling moth that lays its eggs on the fruit. The coddling moth needs to be sprayed frequently, usually every seven days, depending on the insecticide. Spraying should continue through the first week in September. The spray for the cherries begins when the cherries turn a straw yellow, some with a touch of pink beneath, (salmon colored). It should continue up to harvest. The frequency depends on the spray used. If you have further questions, call us at 851-8462 Pat Fugal, master gardener

- Our golden delicious apple tree drops fruit through the entire season. What are we doing wrong? It is located in our garden area and gets plenty of water. Thank you for your help.
- I have much vinca minor (dwarf periwinkle) planted about 20 years ago as ground cover in my yard. Some is in full sun, some is in part sun/part shade. Some small areas of the vinca (3-4 feet in diameter) in several places in the yard have begun the most recent two Springs looking yellow/pale green, not deep green like the rest of the gardens. Neither have they flowered. A couple of the small yellow/pale green areas e thinned, and some of the plants died. The veins in the leaves of the unhealthy plants are green, but the leaves are yellow/pale green. They have remained thus all summer. They don't turn brown and dry and die. I have treated with fertilizer and snail bait, but neither has had any effect on the unhealthy looking plants. Are these plants deficient in some nutrient? Healthy plants I planted in the bare areas had a hard time establishing but did eventually and have not paled. What should I do? I don't want the problem to spread. The periwinkle has added a great texture to the yard.

- 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.

- 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?
- My greenhouse made of visqueen does not allow the sun to hit soil, causing the growth of algae on the surface. What must be done?
- 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?
