I discovered on my peach tree there is a white larvae that has burrowed into the base of the trunk and a sticky peach colored substance is there. The rest of the tree looks healthy, but I only have about five peaches that made it this year. This is the third year for this tree, and when it was only a year oldit produced 35 peaches. Also, there are these black bugs with red heads on the tree that I have never seen before. HELP! I really want to save this tree!

It sounds like your peach tree has greater Peachtree borer. The larva can be killed by inserting a knife or wire into the empty holes. I have included a link to a fact sheet that has more information on this insect as well as recommendations for control and management.
I have also included a link to the sign up page for the Tree Fruit IPM Advisory. This is a newsletter that is sent out with up to date information on pests and diseases happening in our area as well as recommendations. These newsletters have a great deal of valuable information and can be a great help in your home orchard.
As far as the insect goes, it is difficult for me to say for certain what type it is without actually seeing it. If you could bring a sample into our office at 2001 S. State Street #S2100 we can help you identify it.

- We have 2 honeylocust trees in our yard. I would guess "Imperial honeylocust". They seem to be about 15 years old or so. They are spaced about 20 feet apart. This spring one has leafed out and the other is still not budding or leafing out. Over the winter, the one that is not budding turned bright red on the trunk, which we have never seen before. The tree is getting a very few buds and leaves on some main branches (like suckers) but no buds or leaves on the outer limbs. Is there anything we can do to save this tree?
- We have a flowering Japanese Cherry tree that has bloomed beautiful pink flowers until last spring and this spring. Half of it is white flowers and half is very small pink buds. What has happened? It is about 15 years old.
- I have space for 2 fruit trees in my yard. I would like to plant an apple (red delicious) and a peach (red Haven). Are these the best varieties for my area, and how about cross pollination. My neighbor across the fence has a peach tree and I have a crab apple near by.
- I have a small backyard that has a house on the west and north side, a cinder block wall on the east side and a large tree shading a portion on the south side. Due to the high sides of our yard, we tried some part shade/part sun plants last year. But they got blasted in the heat. Our yard doesn't get 10 hours of sunlight but it gets very hot. Can I sucessfully grow a vegetable garden in part of it up against the houses and plant something along the cinder block wall - preferably grapes or raspberries, or other covering plants (can be non-fruit). Can you recommend a plant we can grow along the wall, both in the shaded and sunny parts? Any recomendations for better use of the space?
- I have an older crab apple tree that is focal point of my small yard. About 3 years ago the leaves became infected with powdery mildew. I have been told to not do anything with this, as it will eventually go away and the tree will fine - but over the years it has gotten much worse each spring. There are only about 60% of the leaves that are starting to look healthy by mid-June. Over all, the leaves are withered and this year we have very few blossoms. Another problem: The tree also has four large limbs that come out of the trunk. I noticed that there seemed to be wood pulp inside a place where a branch was cut off years ago. I scooped out the pulp and found that some bug or other creature has created a cavity that goes 6” into the 10-12” diameter limb and a large man’s fist could easily fit into the hole that has been created. While inspecting the hole I discovered a ¼” or so hole in the very back of the cavity, but no sign of the culprit. The limb seems to be doing fine, as the leaves on the branches from this limb are in no better or worse shape than the rest of the tree. I had my tree pruned by a highly recommended person this spring, in hopes that this would help with my powdery mildew problem. I love my tree, what should I do next about my perpetual powdery mildew problem and the unknown culprit who is dinning on my tree limb?
- I live in East Murray, West Holaday, Salt Lake County. We have a large pine tree and want to plant some flowers under/near it. The plants would be along a fence that runs to the east of the tree. Some, very little west sun in the evening. Any suggestions? I would love some long lasting flowers.
- I have a flame amur maple approx 5 feet high and has been planted since spring of '07. It has turned a very pale yellow color and has several branches where the leaves look like they have been burned. It is getting sufficient water. I've noticed that other flame maples stay green and I have read that it should. I don't know what is wrong with it. Help. It also did this last summer. I have applied some iron and it did green it up a little more but not much.
- I would like to plant trees in my park strip, but have a gas line running through the middle. If I hand dig, is it ok to plant trees over the top of the line? What is the depth of gas lines?
