Aspiring gardeners who don't know the difference between a weed and a seed pod will find plenty to dig into on Colorado State University's Master Gardener website. So will those looking for specific information on delightfully dirty subjects like composting and mealworms. The site is an exhaustive font of information for both the seasoned and the stupefied, with tips on everything from lawn care and pest control to plant selection and keeping your window fern alive. Visitors can also ask questions directly of those earthy wizards known as master gardeners. It isn't easy being a green thumb, but CSU's site makes it a little less mind-boggling.
