Top Trees for Winter Landscaping

Many gardeners are proud of their spring, summer and autumn gardens, but they find winter landscape design very difficult.  

There are many trees and shrubs which may add a lot of color with their red or yellow berries, or unusual bark hues.  Others, like evergreen trees, add visual interest in black and white landscape.  Many of those trees attract wild birds providing them with food and shelter. 

When you are looking for your winter trees, choose trees with berries, lovely bark or interesting branch pattern.

The Immortal Evergreen

How are the plants in your yard looking these days? If you live in the North, as I do, your deciduous trees and shrubs are probably looking pretty bare. My sweetgum tree, viburnum shrubs and spirea shrubs were some of the last holdouts. Even my neighbor’s Bradford pear tree, always one of the last to give up the struggle, has shed the remainder of its tardy but oh-so-brilliant fall foliage.

But not all is lost — well, not if you’ve had the foresight to plant evergreen trees, that is. They just keep chugging along, oblivious to the changing seasons. Even that Grim Reaper of the seasons, winter, fails to stifle needled evergreens. Old Man Winter meets his match in this Old Man River of the plant world.

Walnut Tree Thousand Cankers Disease

The spread of this tree diseases continues recently Thousand Cankers Disease was found in Eastern Tennessee.  According to the Tennessee Department of Agriculture,  “the risk represents an estimated value loss of $1.37 billion in black walnuts in Tennessee alone. There are an estimated 26 million black walnut trees on Tennessee public and private timberland potentially valued as high as $1.47 billion.”  This of course doesn’t take into consideration of the additional benefits that these trees are providing for us including cleaner air, stormwater reduction, cleaner water, carbon sequestration…

But this is significant news because Thousand Cankers Disease was originally found in Colorado and is currently in the following nine states Washington, Oregon, California, Neveda, Idaho, Utah, Arizonia, New Mexico, and Colorado.   All of these states, as showcased on the map, are outside of the native black walnut range.  Meaning that the impact of this could be millions of trees as there has been no cure for this disease.
