Landcsaping in crisis. Need a "Landscaping board" site.

HELP !!!

I have an elderly father-in-law with a house that he had professionally landscaped about 16 years ago. He has not really trusted anyone to help maintain his bushes, trees, etc. for years, with the consequence that much of what he has is terribly overgrown.

I have knowledge regarding some of what he is growing, but other stuff - no idea. I need to be able to ID what he has growing so that I can prune it properly, at the proper time of year.

I know there are many gardening forums out there. I am looking for a community (like orchidboard) where there are members that will be able to offer sound advice. Whether in the open forum, or by private message, I would appreciate some advice on groups to seek out. If there are specific members on a forum who are particularly knowledgeable (especially with southeastern USA landscapes; I am in USDA hardiness zone 7b, FWIW), feel free to pass on usernames (private message is fine if you prefer).
