I built an exceptionally productive keyhole garden using cedar fence boards and pipe strapping. Total build cost was around $200 and the results were amazing. Here's complete instructions on how to do it.
While most of the rest of the garden is hunkering down for winter, a couple of the roses are kicking out one more set of blooms. This one is "Peppermint Twist." I think you can tell how it got its name.
Added 8 more ounces of hot peppers and 1/2 TSP of salt. No additional water. Will probably have just one more addition because the weather cold nights are knocking off the pepper plants.
