We bought a house that has quaking aspens around the perimeter of the yard. About half of them are dying or are already dead. What can we do to prevent the rest of them from dying, and what should we do with the dead trees?

Aspen are highly subject to a variety of pests including the bronze birch borer, and to a variety of pathogens. They are also not very long-lived, and are thin barked, so are subject to physical damage from lawnmowers and weed trimmers. For these reasons they simply do not make the best yard or street trees. Depending on the situation and the homeowners preferences, I often encourage them to consider planting more appropriate species, and we have a few tools such as the Tree Browser CD to help them in making that decision.
That said, there are a few ways to successfully manage aspen in a suburban setting. They can be sprayed for the above mentioned pests, but need it yearly and still have the weaknesses mentioned, so I don't often encourage that. In some settings, if a specific portion of the yard is given over to growing aspen on a rotational sort of basis it can work. Aspen sprouts vegetatively, so when older trees dye, or just wherever there is full sunlight on the ground nearby, young trees will be coming up on their own. If left alone they will generally do well.
I have a few in a garden in my back yard and if I didn't mow the area near that garden they would take it over. So by having a garden area where they can successfully send up their 'suckers' they will constantly replace themselves over the years. As old ones dye-out they can be removed, taking care to protect the young ones coming up in the process.

- I have an 8 year old Norway Spruce. It has a section at the base where the needle grow is restricted and the stems look whitish. The rest of the tree has green plush growth and it is about 12 ft high now. It had this problem when I brought it home from the nursery but I thought it would snap out of it. What is this and is there anything I can do?
- My petunias are horribly sticky - I assume thrips are in control although I have tried to keep them washed off (insecticidal soap) and sprayed with a systemic (orthonex). Is there anything else I might try? Would a dormant oil spray work, and if so when would I use it? Also, there are small worms that are probably chomping the blossoms. What would work to prevent or kill them? How do worms can get into my flower boxes, that are at least 6 feet off the ground?
- I have just moved into this new house and I have all these raspberry bushes. They have produced a crop of fruit and I went out and picked lots of berries. The berries themselves look very nice but they are a little small. When I brought them in the house I noticed a couple different kind of pests on them. A black little beetle looking bug and a little tiny bug that resembled the hair on the raspberry. I washed them off, cleaned them and ate them. Now I am all panicked that I will get sick. They tasted good but I have myself all freaked out not knowing if all the bugs got off. Will they hurt me? I want to make raspberry jam with all the berries I have. Is that safe?
- I have a peach tree with lots of little branches that look burnt at the ends. The rest of the tree looks healthy, but the ends of the branches keep turning black and dying.
- I'm planning on using Imidan on my fruit trees. I would like to use a sprayer, but all the application information I've found is in lbs per acre. How much Imidan should I use per gallon.
