It's All About the Oaks!
When it comes to enhancing your landscape or windbreak with trees that remain interesting even in the winter, the oak family (Quercus) should be at the top of your list! Here's why:
Adaptable to Zone 4 growing
Oaks are not only beautiful but also adaptable to grow in Zone 4. If your soil naturally drains well, you're in luck! However, if you have heavy clay or soil that stays soggy, consider finding a better location for planting an oak tree.
Winter Interest
One of the standout features of some oak varieties is their ability to hold onto their dry foliage throughout most of the winter- a quality known as marcescence. If you enjoy leaving your perennial grasses in place all winter, you'll appreciate the similar effect of oak tree leaves. Plus, there's no need to remove the leaves in spring—Mother Nature takes care of it! As new buds begin to swell and sap starts moving, the trees will gradually shed their winter attire.

Ecological function
By planting oaks, you not only enhance your landscape with year-round beauty but also invest in strong, steady growth for the future. Our tree canopy is continuously changing and adapting to the drought, wind, cold, and heat conditions throughout our region. Oaks play a crucial role in their ecosystems. They provide habitat and food for a wide variety of wildlife. Many bird species, including woodpeckers, jays, and owls, rely on oak trees for nesting sites and acorns as a food source. Mammals such as squirrels and deer also depend on acorns for sustenance. The dense canopy of oak trees offers shelter and protection for many other creatures. Additionally, oak leaves decompose slowly, enriching the soil with organic matter and nutrients, promoting healthy soil structure.
