December through March is when I go through my photos, adding to the database, copying some just for my spring job list, and deleting some I no longer need. While I try not to order bulbs or plants, I generally fail but I'm much improved from years ago. There's always that time in April when box after box of bulbs arrive and it's too much to handle for me now.
Like Deb, I go outside in winter to clip back, double check locations for plants (to see if I have room for more), cut back any clematises I had missed, and add more mulch.We've had mild winters, when I'm outside hours a day, and snowy winters when I can "just look" at caladium, coleus, lilies, and try not to order. Everything looks tempting on dismal days.
