I have done a search today for gardening blogs and have added some interesting ones to the links list on the right.
Musings from a Stonehead: an interesting blog on maintaining a traditional lifestyle and making minimal impact on the environment. It has some very informative "musings" with good pictures and many helpful links.
Welsh Girls Allotment details a quest for an allotment, its cultivation and crops. It also plays music whilst you read!
Happy Hobby Habit is a blog by someone who simply loves to see things grow!
Alan Titchmarsh has a website which I have included simply because it contains a wealth of information and advice in friendly understandable language that even gardening novices like me can understand.
