Snarky Gardening Tip #471: March is about MUD. That is, when outrageous lows don’t freeze it solid. So let’s start again. April is about MUD, or at least it will be.

Leave your mud alone and put those twitching fingers to work sharpening your tools, building sheds and composting all those pots you thought would be okay outside this winter.
