I've been watching
OneYardRevolution Frugal & Sustainable Organic Gardening lately over on youtube. They do a lot of very precise how-to regarding gardening, and I find it quite soothing to have running in the background, not to mention informative! They focus on things such as what to grow when, how exactly to keep your plants happy, how to build things for the garden, and tend to also mention how to adapt their recommendations for different climates.
