Question
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!
Answer(s)
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.

- 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?

- Last fall I planted a 4-foot tall Arizona cypress (Blue Ice) in my yard. I bought it from a local nursery who assured me it was cold-hardy enough for this area, but by this spring most of the needles on the upper 2/3 of the tree had turned brown. The lower needles that were beneath the snowpack for most of the winter are still green. Is there anything I can do to help this tree recovery (or should I find a different tree that's more cold-hardy)?
- Just moved to where we have a very large backyard. I want to plant a large variety of fruit trees, but I don't know what will grow well in this climate. What types of fruit grow best in the Salt Lake area? (eg peaches, apples, nectarines....?) And which kind of each fruit would you suggest? I'm also new to this, so where should I go to buy the trees and find info on how to grow them correctly?
- Two years ago I moved into a house that has a large apricot tree in the backyard. Last year was our first apricot harvest. The apricots got large a ripe, and looked great. But when I picked one and tasted it, is was VERY mushy and bland. Upon further investigation, all the fruit was this way. Does this mean that the tree is too old or maybe just a bad tree? I don't want to deal with the hassle of a fruit tree if I can't use the fruit.
