When it comes to trees, not all species are created equal. While some trees can add beauty and value to your property, others can be a nuisance and even a danger. In Colorado, there are a few species of trees that are particularly problematic. These include the tree of heaven, Russian Olive, and Alder Maple.

  1. Tree of Heaven: The tree of heaven, also known as ailanthus, is a fast-growing tree that can reach up to 80 feet in height. While it may seem like a good option for quick shade, it is an invasive species that can outcompete native plants and cause problems for property owners. Its shallow roots can damage sidewalks and foundations, and it is known to produce a foul-smelling odor. It also has a tendency to be short lived, and it can be a problem because it is not a long lasting tree.

  2. Russian Olive: Russian olive is another invasive species that is commonly found in Colorado. This tree can grow up to 30 feet tall and has a distinctive silver-green foliage. While it may be attractive, it can be a nuisance as it produces a large amount of fruit, which attracts birds and wildlife. This can cause damage to property and create a mess. Additionally, it is known to outcompete native plants, and it can be difficult to remove once it is established.

  3. Alder Maple: The Alder Maple is a tree that is known for its shallow roots and susceptibility to disease. It is a tree that is prone to disease, and it can be a problem for property owners. Its shallow roots can damage sidewalks and foundations, and it is known to produce a foul-smelling odor.

Should everyone of these trees be removed if they are in your yard? The answer is actually no, sometime the wrong tree was planted in the right spot and you as the home owner like the tree and the utility it provides, and we get that.
