Creating Winter Window Boxes
The first thing to remember when creating winter window boxes is that some plants will keep producing and even perform better after a frost. Swiss chard, kale, parsley, and mint will all thrive through a frosty autumn. You can plant them in late summer when hotter weather plants start dying. Alternatively, if you plant everything in grow bags, you can start them indoors earlier and switch them out to your urban window box gardens when the temperatures start to drop.
Window Flower Boxes in Winter
If you want plants that will truly last the winter, try growing winter-blooming plants. There are actually many to choose from like hellebore, winter jasmine, and daphne to name a few. Likewise, you can plant miniature evergreens in grow bags, switching them outside when everything else has died. If you don’t want to plant anything, of course, or if you don’t have grow bags, you can always decorate your winter flower boxes to look like they’re full of life and be very festive about it. Cut some evergreen shoots and holly boughs with berries on them. Tuck the ends into the soil– this should help to keep them looking fresh for a month or two. If they start to fade, simply switch them out for new branches. The snowfall won’t hurt them, and they might even look better for it.
