Plants With Winter Interest

    The winter garden has a quiet beauty. No longer overwhelmed by the lush foliage and exuberant colors of the summer and fall garden, subtle changes in texture and hue are readily appreciated. The varied structures of deciduous trees and shrubs become fascinating. Bark intrigues.

    Stand at the curb and take a look at your home. Stroll through your yard. If quiet beauty, appreciation, intrigue and fascination are not words you would choose to describe your landscape, consider adding some of the plants listed below.   

    Use a backdrop of evergreens to contrast texture and highlight the bark color of deciduous shrubs. Position a fuzzy looking needled plant next to a shiny broadleaf evergreen to make both look more interesting. Contorted branches add drama. Berries, flowers, and bark add pops of color. Several spring bloomers have the bonus of a sweet fragrance.

Walking Stick in FlowerWalking Stick
Corylus avellana 'Contorta'

    Comon names: Harry Lauder's Walking Stick, Hazelnut, Devil’s Walking Stick, European Filbert.
    Planted in well drained soil, in sun to partial shade, this deciduous, twisted stemmed shrub usually grows to 8-10 foot tall with a similar spread. The flowers appear in early to middle spring are yellowish-brown "catkins”. However, this shrub is not grown primarily for its blooms but for its unusual branching adding winter interest to a garden.

Red Heleborus in flowerHellebore
Helleborus

Distinctive, long-lived evergreen plants, ranging from 18 to 36 inches, blooming for several months in winter and spring. Plant this perennial in good amended soil in partial or full shade with regular to moderate water. The Lenten Rose is the easiest of the Helleborus to grow

Another year has begun.  Resolutions have been made (some already broken). 
Maybe this year will be the year to start a vegetable garden or a new flowerbed. 

TREES, SHRUBS & ORNAMENTALS

  • Cold, dry winter winds can remove moisture from the soil and from plant tissues very quickly. Don't forget to water newly planted trees and shrubs if it has been more than a week without rain or if the soil is dry around the plant.
  • Protect plants from weather extremes. Wide swings in climate – balmy breezes one day, arctic blast the next – can be really hard on plants.  https://www.ces.ncsu.edu/depts/hort/hil/hil-604.html
  • Remember: Watering just before a cold snap can help plants survive bitter temperatures!Bagworms on Leyland Cypress
  • Check bare shrubs for insects – They often overwinter or lay their eggs on the twigs of plants (ie. bagworms).  Remove and destroy them before they hatch in the spring. 
  • While looking for insects examine plants for Dead, Damaged, or Diseased limbs that should be pruned out.  Also look for crossing limbs that may rub against one another and prune one of them away as well.
  • Red Amaryllis in vaseCheck holiday plants  and gift plants for insects before locating them near your other plants.
  • Enjoy winter-blooming perennials such as Rosemary, Erysimum (wallflower), and Hellebores. Evergreen ornamentals and shrubs, especially those with berries, add color to the winter landscape.
  • Amaryllis  blooms best in tight quarters. Use a pot that provides only about an inch of space from the bulb to the sides of the container.  https://www.ces.ncsu.edu/depts/hort/hil/hil-8529.html
  • Enjoy those catalogs – but beware glowing claims of "blooms all summer," especially from companies based in northern states. Some of those plants really are great, but some are not well adapted to our growing conditions! Look for key words like "heat resistant" or "tolerates humidity." Talk to Master Gardener Volunteers for information on plants that are well adapted to our area.
  • Trees and shrubs infested with scale or spider mites can be treated with a horticultural oil which works by smothering pest eggs, larvae, and adults.
  • Clean up fallen leaves and build a compost pile. Do not include leaves from diseased plants.
  • Thinking about growing plants indoors under fluorescent lights?  Four-foot tubes are generally the cheapest; mix cool white tubes with warm white ones to provide a wider light spectrum.
  • Divide perennials like daylily , shasta daisy and peony  when the ground is dry enough toOrange daylilly clip art work.
  • Prune broadleaf evergreen shrubs such as holly and boxwood.
  • Deciduouse shrubs that bloom on new growth may be pruned now.  Examples include vitex, Rose of Sharon, and butterfly bush.
  • Winter-blooming camellias (Camellia japonica) should really start to show off this month, but after the show, rake up and dispose of fallen flowers to help discourage camellia petal blight.
EDIBLES
  • Beets, carrots, peas, lettuce, mustard, radish, spinach, irish potatoes, and turnips can be sown outside as early as the beginning of February.
  • Leaves of chard on tableGrow cold-tolerant leafy vegetables such as lettuce, spinach, and collards . Some may be killed by frost, but it's worth it to have fresh greens for salads. Try planting greens in with your pansies for a pretty and useful winter garden.
  • Don't forget to ventilate cold frames on warm sunny days.
  • Mulch strawberry beds for winter protection with a layer of wheat straw or pine needles 2-3" thick. Pull the mulch back when blooms appear.
  • Asparagus crowns can be planted now through March.
  • Order seed catalogs, and plan your garden.  Choose disease resistant varieties.
HOUSEPLANTS
  • Let your houseplants rest. The four major causes of houseplant deaths during the winter A red Christmas Cactusmonths are over-fertilizing, over-watering, under-watering, and improper light. Most houseplants are semi-dormant in the short days of winter, so do not fertilize them. Your plants will rest and be ready for vigorous growth in the spring.
  • Keep an eye out for indoor insect pests; most can be controlled easily with insecticidal soap.
  • Check stored bulbs, tubers, and corms such as dahlia, caladium, and gladiolus. Soft rotting tubers indicate too much moisture; discard any that are soft, and move the healthy ones to a drier place. Shriveling roots and tubers indicate that the tubers are too dry, so slightly moisten the material in which they are stored.
