Question: 

When should I prepare my hybrid tea roses for winter?

Answer: 

Prepare hybrid tea, grandiflora, and floribunda roses for winter after the plants have been hardened by exposure to several nights of temperatures in the low to mid-twenties.  Normally, this is early November in northern Iowa, mid-November in central areas, and late November in southern counties.
