What has been your experience purchasing plants from the big box stores - Lowes, Home Depot, Fred Meyer, etc. For the most part, I steer clear of these, thinking they may be full of bugs or not watered regularly (some certainly look pretty scrappy). I don't, however, want to become a plant snob, so am wondering if my fears are founded or not. I presume their prices are less than a nursery. I have to actually drive to get to a big box (and gas becomes an issue), so I rarely frequent them. I also don't do well in big stores - Costco is not even remotely in my universe. Reactions?
