I live in a cold climate, so my own personal December to-do list for the yard isn't very long. There will be some stray fallen leaves left that I may get around to picking up (assuming it hasn't snowed yet by then). Maybe I'll also take advantage of my plants' dormancy to do some transplanting that I didn't dare try earlier. Early in the month I'll protect some plants from wind damage, while the weather's still hospitable enough that yours truly won't be suffering any damage on his own part from stepping outside.
But if you live in a warmer climate, you may wish to check out Marie Iannotti's list to see what you should be doing next month. While I'm far from being a workaholic, I must admit that I envy you!
For the rest of us, December is all about planning ahead, making plant selections for next year's landscaping. There's a lot to be said for the joys of anticipation. I do take my garden somewhat for granted during the summer, when stepping outside and enjoying blossoms like those on candytuft (picture) is a daily occurrence. Absence makes the heart grow fonder, and I can assure you that I take nothing about spring for granted!
