The tree is brown on most of it. Is there anything I can get to save it or is it too late to save? My other trees are fine.

Since Bayer have monopolized the market, they have stopped producing concentrated multi-rose concentrate 1 in 3 and sell it by diluted 1 litre bottles. We normally use 4 litres on our blue spruce. Is there any way around this blatant exploitation for poor pensioners like myself?
Perhaps you could directly contact the manufacturer to inquire about purchasing different quantities of their product.
Here is a link that may offer you some alternatives to rid the spider mites.
Our blue spruce has about three tips. Why is this and is there anything we need to do to make it a single tip? The tree is healthy otherwise, but we need to find out if we need to cut or clip one or two of the tips. We don't want it turning into a short shrub. Thank you in advance.
Here is a link that recommends choosing one leader and removing the others.
I have a very tall Blue Spruce that is losing it's bottom branches. What can I do? The tree is very tall...I'm guessing 30 ft and it looks beautiful from about 4 ft up, but the bottom branches are bare and it's getting worse and going farther up.
If the upper branches provide too much shade, the lower branches naturally die off.
On a more serious note: It could be Cytospora Canker, Rhizosphaera Needle Cast, or Stigminia Needle Cast, which are all discussed in detail on the following website:
It could also be the handiwork of a spruce spider mite:
I recently moved into my house which faces the south. So far I have had to pull out 5 medium sized shrubs because they died. My blue spruce is turning brown as is another evergreen. In another area in the front of the house, the hydrangeas are dying. If I walk around the property, I see at least 4 more dead or dying bushes. Some hostas on the side of the house are dying. I live on Long Island and we had a wet spring. I have been watering regularly. We did find a bird house behind a bush that had some bugs on it (grub-like). My lawn is also getting brown spots. Any ideas?
It may be that the plants are getting too much water. outdoor plants only need about 2-4" of water a week, including rainfall, during the spring and summer. If they are getting more than that and the ground is not draining, the roots could be rotting. You need to make sure that the plants are only getting the amount of water they need and that they are not in standing water.
Another possibility is that there are grubs. The ground may have grubs that are attacking the grass and the root of the shrubs. This article will help you with that:
Will blue spruce live in northern Louisiana?
I would not recommend it. Zone 7 is as far south as it will grow and then it's stressed from the summer heat. However, you may want to check out the Arizona cypress. This would be a better choice and great substitute.
I have two small blue spruce trees (18" high) planted in large pots, which have been outside framing the front door(faces southwest) since spring. Will I need to winter these inside or in an unheated garage or what would be the best choice? Some winters we can get as cold as -20.
You will not need to winter the trees inside.
The are winter hardy to zone 3.
Continue to water the trees into the dormancy and add a small amount of water a few times throughout the winter.
