Experts and BHG readers answer.
What gardening region am I in?
According to the Oklahoma County Extension Service, you are in US Dept. of Agriculture gardening zone 6b. The USDA determines gardening zones based on how cold it can get in the winter. Check with the county extension service to be sure you are using landscape plants that will survive the cold winters in your zone. Thank you for your suggestion on having a zip code/gardening zone service on the BH&G site. I will pass it along to the site designers.--Stephanie Hainsfurther, Albuquerque, New Mexico
