When the bright blossoms of summer are faded and leggy, your window box doesn’t have to sit empty and forgotten. Plant a fall window box to add seasonal color to your home. Choose hardy flowers or even vegetables, or add non-living decorations. First, remove summer’s faded flowers and loosen up the soil. Wash the outside of the window box or repaint for a fresh look. Then transform that window box into a fall accent.
Purple asters, golden, bronze and maroon chrysanthemums and purple, blue and yellow pansies add bright color to window boxes. These flowers thrive in cooler temperatures and will survive the first frosts. An early snow my wilt the blossoms, but if temperatures warm again, blossoms will return. Feed with a mild fertilizer to keep them blooming.
Hardy green plants such as English ivy will provide good contrast for the fall flowers in your box. Or skip the flowers altogether and choose plants that provide the color and texture of flowers. Flowering Cabbage and Kale in shades of green, white and purple add a surprising punch of color. These ornamental vegetables intensify in color after the first frosts and will last well into winter.
If you live in a part of the country where snow arrives in October, consider “planting” evergreen boughs in your window boxes. Cut the tips of branches from pine, balsam fir or cedar and anchor the boughs in the window box with garden staples. Add ribbons and other decorations for an attractive window box arrangement you can leave out until spring.
Instead of flowers, fill your window box with pumpkins, gourds, Indian corn and other signs of the season. Prop a stuffed scarecrow in your box, or a Halloween witch.
