Here in Bay Country, we have an abundance of evergreen plants to choose from. Many — but not all — narrowleaf greens will hold their needles if you treat them right, while adding beauty and aroma to your home. 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. Japanese hollies are plentiful, but their foliage does not stay as attractive for as long as the other varieties.
A few species don’t retain their needles and should be avoided, among them hemlock, Norway spruce, Cryptomeria, red cedar and Japanese privet.
You need not worry about damaging your ornamentals by pruning them this time of year, when the plants are dormant. If you limit your pruning to stems one inch or less in diameter you will not stimulate them into growth or make them more susceptible to winter injury.
Boxwoods, another long-lasting holiday green, take another pruning approach, borrowed from Colonial times: breaking off branches for making decorations. In cold weather, boxwood branches become very brittle and can easily be broken from the main stems. This may seem crude, but it is a very effective method of pruning boxwood and making maximum use of the prunings.
Boxwood branches have many decorating uses, such as in making wreaths, sprays, kissing balls and centerpieces. To increase their longevity in the home, carry along a pail of hot water, about 100 degrees, and immediately place the broken end of the branches in the water. The cold stems will absorb the hot water readily.
By breaking branches 12 to 14 inches long, you punch holes through the boxwood canopy, allowing light to penetrate into the center of the plant. Breaks made when temperatures are low are clean and will heal quickly come spring.
Another advantage to pruning boxwoods by breaking branches during winter months is you have more time, so you can do a better job. Winter pruning also gives you a head start on spring pruning.
Still another advantage of breaking branches is that you reduce the chance of spreading canker diseases from plant to plant. Pruning boxwoods during summer months with hedge or pruning shears increases your odds of spreading these diseases from plant to plant with the tools.
Increase the life of decorative greens by cutting one to two inches from the base of the stem as soon as you bring them indoors and immersing them in 100-degree water. Change the water at least every other day.
Spraying the foliage with Plant Shine after it has been in warm water for about an hour will improve the appearance and help reduce the need for water. Plant Shine is just as effective but less messy than Wilt-Pruf or Vapor Gard.
