The Bay Gardener’s Guide to Evergreen Holidays

Buy a Fresh, Safe Christmas Tree
    For the freshest Christmas trees, buy locally from a Christmas tree grower’s lot or cut your own. Otherwise, you could be buying an imported tree cut in late October or early November.
    Fresh-cut Douglas fir, Scots pine and blue spruce are the most fire-safe Christmas tree species, ranked by the State Fire Marshal based on research conducted by the Bay Gardener in cooperation with the Maryland Christmas Tree Growers.
    Fraser firs are not fire safe. Do not buy them.
    Once you bring the tree home, cut an inch from the bottom of the trunk and place in a bucket of 100-degree water. Keep the tree and bucket in the shade until you are ready to bring it indoors. When you bring it in, cut another inch from the trunk and immediately place it in water. Make certain there is always water in its stand. A good Christmas tree stand should hold at least one gallon of water.

Wreaths and Roping, Too
    Most of the Christmas wreaths and roping sold in big-box stores, grocery stores and many garden centers are made in New Mexico, North Carolina, New Jersey, the West Coast and Canada starting in October. Few of these facilities have climate-controlled cold storage for keeping greens fresh prior to shipping. Most are stored on the floor in sheds and barns and sprinkled with water when they appear to be drying. By the time they reach Maryland, they have already lost a high percentage of their moisture.
    At Upakrik Farm, I wait to make wreaths and roping until Thanksgiving week to assure freshness. I store them on the barn floor in stacks no greater than 10 deep to prevent compression and to assure adequate moisture. I sprinkle the wreaths and roping daily to keep them moist and cool to maintain freshness. Because I sell only freshly made wreaths and roping, I have many repeat customers at the Riva Road Farmers Market. There is no substitute for freshness.

Gather Greens in Your Garden
    For long-lasting holiday greens, gather arborvitae, Canaan fir, Douglas fir, junipers, Nordman red cedar, red pine, Scots pine and white pine. Many broadleaf evergreens will also hold up throughout the holidays. Choose from American holly, cherry laurel, Chinese holly, English holly, English ivy, mountain laurel, pachysandra, periwinkle, rhododendron and southern magnolia.
    Increase the life of greens by cutting one to two inches from the base of the stem as soon as you bring them indoors and immerse them in 100-degree water. Change the water at least every other day.

If You’ve Got Winterberry Holly, Bring It In
    Winterberry shows at its best this season, inviting you to cut it for Christmas decorating. The native deciduous forms of holly grow as shrubs six to eight feet tall. At this time of year, the ends of the branches are filled with clusters of bright red berries.
    Use extreme care when cutting the stems to minimize shedding berries from the stem. Once they are cut, do not put them in water. Since the berries shrink very slowly, they will remain attractive for a month or more indoors. Thus, they’re ideal for making dry arrangements or for decorating the Christmas tree.
    Holly berries are not poisonous, though neither do they taste good.

Keep Poinsettias Pretty
    The brightly colored bracts and dark green leaves of poinsettias make them the ideal Christmas plants. Varieties are better now than ever before. Now available in many shades of red, white, pink and speckled, they retain their bracts and leaves longer with minimal care.
    And no, they are not poisonous.
    Keep your poinsettia fresh looking by careful watering. Check the growing medium daily for adequate moisture by pressing your finger into the medium halfway between the stem of the plant and the wall of the pot. If the medium feels cool and moist, there is adequate moisture. If the medium feels warm and dry, water thoroughly.
    Add water until it flows through the bottom of the pot. If water flows immediately through, the medium is too dry to absorb water. Soak the pot in a basin or pail of warm water for 30 minutes to an hour. Drain the plant before returning it to its place.
    Avoid overwatering. Poinsettia roots are very susceptible to rot.
