January and February
Mulch to keep moisture even and weeds away.
Prune non-flowering evergreens shrubs.
Winter (up until the end of May) is a good time to re-do foundation plantings. This allows plants to get roots set in without a lot of watering.
Treat boxwoods for leaf miners that hatch in spring.
The best time to do severe shrub rejuvenation pruning. This takes advantage of the spring growth spurt to fill plants leaves back out.
The best time to start a perennial garden because many of the evergreen flowering perennials, like Creeping Phlox, Candytuff and Dianthus, are only available in March into early April.
