When it comes to adding new trees to your landscape, including those with an abundance of shade is a great decision. These trees not only shield the sun from us while we’re outside, but also shade and cool our homes. This natural air conditioning system can cut down on cooling costs during particularly warm months. These large trees can also act as a wind barrier, cutting down on heating costs. The soil in cities such as Orono, Minnesota is ideal for planting trees, especially shade trees. Below are some of the more popular shade trees that will take well to Minnesota soil.
Out of the many types of oak trees available, Bur, Pin, Red, Swamp White, and White are the most highly recommended for Minnesota and can range in heights between 30-80 feet. Their fall leaves cover a rich palette of orange, brown, and red. These are tolerant of a wide range of soil types, though changes in the soil level can affect the roots. Red Oaks are more susceptible to oak wilt than white oaks, so be sure to avoid pruning these during April, May, and June, when they are most vulnerable.
Maple trees come in a variety of sizes, so it’s important to know which will grow to a substantial size, providing an optimal amount of shade. Norway, Red, Silver, and Sugar grow 50-80 feet. There are a variety of maples that are unique and add vibrant colors to your landscape. Silver Maples are most commonly planted because of their ability to block the sun and wind and withstand our harsh winters. Young maple trees are prone to sunscald, so be sure to wrap their trunks each fall.
There are three types of Linden: American (or Basswood), Greenspire (or Little Leaf), and Redmond. They grow between 40-80 feet and vary in leaf-type and care. The fullness of the tree depends on the space they are given to grow. Lindens in densely wooded areas are slender, whereas Lindens grown in open areas are full and rounded. The American Linden is an animated choice, producing small, white flowers in late June and a yellow leaf pattern in the fall.
Elm Trees are a desirable tree choice when picking a shade tree for your yard, but it is important to make sure you are planting one of the many Dutch Elm resistant varieties. Two varieties we recommend are the Valley Forge Elm and the Princeton Elm.
It is fine to plant deciduous trees to overhang above another object, such as a sidewalk or driveway, but avoid planting so close to the object that it might obstruct the tree’s growth. Keep the adult tree height in mind when planting near power lines, as this could create a safety hazard to your community and your tree. Be sure to leave ample room for the roots to grow.
