I would call Bedford. They are great.
I agree with Dee Felt! I usually ask them at Bedford, Lowes, or Google it.
I really don't know. Whenever I have a gardening question I go to Bedford and ask the people there. They always are very helpful and are very knowledgeable about gardening, plants and even the soil conditions in this area. I would trust them over any of the big box stores garden centers.
