I have a friend with a lot of blue spruce, cedar and other pine trees that I
don't recognize. He is getting ready to lose a lot of them if we don't do
something soon. Most of them are mature trees, but he has about 30 that are
less than 5 years old and has ordered another 50.

How often should they be watered? What kind of fertilizer do we need to
use. The pH here is usually 7.5 to 8.5. How often and what do we need to
add to keep it down around 6.0?

Thanks. Dwayne
