DEFINrnON OF GROWING SEASON 



1989 MANUAL: 



Used growing season zones mapped in broad bands across the country according 

 to soil temperature regimes. 



PROPOSED REVISED MANUAL: 



Growing season is based on local weather data, and will be from 3 weeks before 

 the last killing frost in the Spring to 3 weeks after the first killing fi-ost in the 

 Fall, except for areas that experience freezing temperatures throughout the year, 

 where appropriate local growing seasons will be applied. The local weather data 

 will be available on a local level, e.g. the county level.
