On of My Favorite Sites!
Dave's Garden, affectionately known as DG to members, originally carried the label "by gardeners, for gardeners". It has a wealth of information about gardening and a host of other topics. Member benefits include: an expansive plant database, insect database, 100's of discussion forums, member led plant purchasing co-ops, plant and seed trading, the Garden Watchdog (member ratings and comments on nurseries and plant suppliers), garden journals, garden blogs, and much, much more. It's a friendly site where members can talk one on one with admins to ask questions and resolve problems. Site members are among the friendliest and most helpful you will find anywhere.
