I've recently joined up with a couple of different forums with the aim to learn more and be stretched with new ideas and information about gardening. Forums seem like they've been somewhat superseded by blogging but I can assure you this is not the case.

Most gardeners don't blog for various reasons, the main one being they like to garden but aren't interested in keeping a web presence. Many of these non-blogging gardeners have a wealth of information that they're happy to share in a forum setting that only requires the setup of a login and password. They don't need to plan a blog, concern themselves with design and then worry if people don't like what they say.

I would personally recommend that every garden blogger also avails themselves of such a rich information source and actively dialogues with other gardeners whether they be Master Gardeners or complete novices. There is too much to know about gardening and this is a great way to keep learning and helping others to do the same.

Some great forums that I participate in are GardenWeb's forums and also Homestead's Garden forums. If you're after more, or even localised forums just run a search query through your preferred search engine.
