i'll think about my garden when ever i look in the backyard and see the empty raised bed but still way too soon here in CT to do anything but plan. General rule of thumb in my neck of the woods is to not plant anything in the ground before May 15th, although i usually try to start plants inside or on the deck(which can be a pain to bring in and out if a late season freeze comes) in April. I know some people who even start growing plants indoors in March.
On a different note but still related to gardening, I just read an article the other day that in part because of the unusually warm weather in the east and the use of plastic tarps (like a greenhouse) The White House's vegetable garden has been growing cold weather crops all winter, at least according to one of the head chefs. I thought that was pretty cool, i wish i could build some type of greenhouse to grow vegetables all year round!
