The garden is just two years young, and I am doing alot of mulch and cover crop. This year I also got a little bit of biochar to work into a few beds. I decided to sell my rototiller, and start gardening the Ruth Stout no till method (my modification). This year was a good year for rain, so I only watered few times.
Blue barrels around here are up to $27 each. I can also get some of the big plastic cube tanks with the metal frame, but they are pretty pricey too. Guess I will look into some ferrocement/ pond and hope I can get a liner or fish pond on craigslist or freecycle. Maybe an old hottub for a pond.....people give koi away around here.
