We have thousands of little green worms/caterpillars hanging from webs in our trees, eating the leaves til they are bare. What can we do to get rid of them?

I cannot positively identify which caterpillar you are asking about, because I don't have enough information. But I suspect you are asking about the oak cankerworm, which is a looper type of caterpillar that hangs from silken threads and eats gambel oak.
Read about this insect and how to control it in the USU Extension publication on Gambel Oak, at http://extension.usu.edu/files/publications/publication/HG-514.pdf
There are other caterpillars that feed and nest in trees. You can read about them at the Colorado State University website:

- I have read that one should water infrequently and then water to penetrate 6 to 10 inches especially if one has necrotic ring spot. I live in Sandy where the top soil is only four inches and then sand and rock. Does it make sense to water 6 to 8 inches? Also does necrotic ring spot live in sandy rocky soil? Is it possible to control or eliminate the necrotic ring spot by using a service or must I excavate and if so to what extent?
