Adding Appeal to the Winter Landscape

Ensure your yard has winter pizzazz. Bring color, texture, structure and movement with the right plants.

When you look out your kitchen window or pull into the driveway this winter and cringe at the lack of appeal, you need to add some winter interest to your landscape.

 

Evergreens, fruit, seed heads, and bark will add color and texture to an otherwise monotonous garden bed. Shades of greens, blues and purples will pop against a white canvas with evergreens. There are some great dwarf selections like 'Acrocona Pusch' spruce or 'Minuta' eastern white pine that will fit nicely into front foundation plantings. Also bring a bit of red, orange, or blue/black into the color palette with fruit from shrubs. Look to winterberries, snowberries, viburnums, and many crabapple varieties for their winter fruit display.

 

Don't forget that several tree varieties maintain intriguing bark. We're aware of the birch species with its exfoliating bark, but also look at amur chokecherry or shagbark hickory.

 

Incorporate perennials and ornamental grasses for their seed heads. Sedum, coneflower, and black-eyed Susan are always popular, but add blue false indigo or globe thistle for a twist. The fluffy seed heads of clematis had texture too. Switchgrasses, feather reed grasses, Miscanthus spp., and prairie dropseed will bring structure, movement, and texture to winter beds.

 

Even a plant's branching structure can bring a bit of interest to an otherwise dull landscape. The horizontal branching of pagoda dogwood or honeylocust captures snow. The twisting and curling branches of Harry Lauder's Walking Stick (Corylus avellana 'Contorta') is quirky. Consider adding weeping forms of trees and evergreens such as 'Louisa' or 'Ruby Tears' crabapples or 'Formanek' spruce or white weeping pine.

 

And just when you think you can't handle more snow shoveling, you'll notice the early spring bulbs trying to peek out.

What's Blooming? Birches

Besides a stunning fall look, 'Prairie Dream' birch adds a lot of winter interest.

Look to birch trees to add seasonal interest during winter.

 

Paper birch, Betula papyrifera, will grow to a height of 50-75 feet and 35-40 feet in width either as a single stem or clump. The best place to plant paper birch is on moist, fertile, cool sites, otherwise it is likely to be killed by the bronze birch borer. The site can't be wet as it is flood intolerant. Paper birch has a yellow fall color.

 

Check out your local nursery for 'Prairie Dream' paper birch. This selection has the snow-white exfoliating bark and gold fall color. It's more adaptable and stress-tolerant than the species and less susceptible to birch borer attack. 'Prairie Dream' is a great accent tree, and one of the best for winter value.

 

River birch, Betula nigra, develops a gorgeous cinnamon-brown peeling bark as it ages which adds significant winter interest. This single stem or clump tree is adaptable to a wide range of soils, but prefers acidic soils. It will likely suffer from chlorosis in alkaline soils. River birch will grow to 50-75 feet tall with a spread of 45 feet.

 

'Fox Valley' river birch is a great compact river birch for use in smaller garden spaces. 'Fox Valley' is a dense multi-stemmed deciduous tree that will act as a large shrub than a tree.

To Do List for November

Get rid of the thick layer of leaves to protect the lawn.

1. Remove leaves from lawn. Rake or do a quick bag mow to remove leaves. A thick layer will block out sunlight and may smother the grass.

 

2. Mow grass to a height of 2 to 2.5 inches. Grass has stopped growing, but should be mowed down to reduce the chance of snow mold.

 

3. Continue watering. Water trees and evergreens until the ground is frozen.

 

4. Apply late season nitrogen fertilizer application. It will be absorbed now and accessed next spring. Then water 1/4 to 1/2 inch to move it into the soil. Never apply fertilizer to frozen ground. You want about 2 to 3 weeks of unfrozen ground to allow for root uptake of nutrients.
