There's a garden radio program hosted by a local nurseryman and landscaper that I listen to each Saturday morning. You can listen online between 8-10 each Saturday morning. The link is provided. Archive programs may also be available. The broadcast is generated from Bakersfield, California which is zone 8-9. They provide an 800 number if you would like to call in a question for them to address. They sometimes have "give aways".
Hope this is helpful.
