Use branches from your home landscape or buy freshly-cut greenery at garden centers or Christmas tree lots.
Use pine, spruce, cedar, fir or juniper branches. If you purchase the branches, re-cut them to allow them to take up more water. Apply a spray such as Wilt Pruf or Wilt Stop to keep them fresh for an extended period. These sprays are also a great help to keep cut Christmas trees, wreaths and garlands from drying out, as well as evergreens in the landscape that get "winter burn."
This burn is the result of the needles drying out. Spray greenery on a relatively warm, still day. One application is sufficient for the season.
It's usually safe to leave glazed ceramic pots outside in winter but terra cotta ones often crack. Empty the terra cotta pots and store them, but other pots may be filled with fresh greenery. Use the soil that's already in them for convenience and keep it moist to keep the boughs fresh. Some people use inexpensive plastic or fiber pots for the greenery arrangement and then insert it in a more decorative pot.
Lights may be added to the greenery or you may also wish to add artificial branches of winter berries and such to add sparkle and color. Natural materials from your garden should also be considered, such as bare willow or red twig dogwood branches or seed heads of ornamental grasses or perennials. Accent your holiday porch pots with bows or bells to your heart's content.
