Does pine straw help protect against the cold in the winter?
Yes, if you place pine straw around the base of your tree or plants, pine straw works very well at protecting the root system from the cold during the winter months. If you are trying to protect small trees, place the pine straw around the base of the tree with about a two foot diameter. The pine straw will need to be at least three inches thick. If you live in a very cold area, place the straw about six inches deep to help keep the cold out.
