bugs on my tree

I hope you can maybe help me with a situation that we are having. I've been getting the run around from everyone else I've asked. We moved to our current location appox. three years ago. When we bought the house, the flowering crab apple tree in the front yard was beautiful. This year the leaves have been turning yellow right away and have brown spots on them. We also have gotten some of those wormy nests in the tree. We've been trying to kill them as soon as we see them. They're the nests that look like huge spider webs. Now though we have a nest at the very top of the tree which is about 35 feet in the air and we can't reach it. What can we do? Does the tree need to be sprayed throughout the year? If so, with what? Any help you can give with this would be greatly appreciated.

Also, we would like to plant some shrubs/hedges this fall. We have approximately 400 plus feet on the west side of the house. What we are looking for is something that will survive in somewhat sandy soil. It's not all sand, but my husband said it's sandier than normal. We would like something that would provide a good noise break from the highway that's right there and something that would provide a little privacy from the nosy neighbors. Any suggestions?

I really appreciate any assistance you can give me in my two situations.

thank you again.

Jessica,

What you may be experiencing with your crabapple, is a worm type fellow that also gets into cherry trees. The best way to combat this is this fall spray the tree with durispan or malathion into the nest and surrounding branches of the tree. Also, spray the trunk of the tree and the surrounding soil out to the drip line of the tree. This spring you will want to do the same early on just before and just after the first leaves appear on the tree. Almost forgot, you will need to add some kind of surfactant with your spray to extend the effect of the insecticide to produce the desired results. Surfactant is a sticker much like a mild glue that will keep the insecticide on the branches even after a rain. The reason to spray the ground is that it will keep any critters from crawling up the tree. I would say that you may have experienced some stress to the tree, such as drought, that weakened the tree enough to make it more susceptible to insects.

In response to your second question there are a number of shrubs that grow in sandy soil that will produce your desired affect. This will depend on which area of the country that you reside. If you are in zone 5-9 you can use a plant that we sell called fragrant honeysuckle that is a semi-evergreen and will grow to 6 to 8 feet. Look around our site at the various plants descriptions and if you need additional help feel free to call.
