frost in Mississippi, at Brussel's Nursery #1

At the beginning of December 2006 Bill Nelson and I went to Brussel's Nursery in Mississippi, just south of Memphis, Tennessee.

This is by far the biggest nursery in North America. One must go there, at least once.

Frost is not so common in the South. A real lot of stuff ist stored outside. This can cause a problem when severe frost happens overnight. In Florida it was found out that the orange
trees could be protected by misting them over night with water. The branches would have
ice all over and would be protected from frost. At Brussel's they do the same thing. It looks bizzarre.
