I have just signed up for a free online gardening course. Here is the link: Log In When you register you have to choose the Master Gardener basic botany, the others cost $20.00 each, which still isn't too bad for a University course. I am still waiting for my registration email to come, I have had to write them once already because it didn't come and they wrote me back right away and seemed very helpful. If anyone joins, please post here and maybe we can share thoughts on what we learned. ;-)
