“Location, location, location”: one of the most well known concepts when it comes to real estate. The same concept can be applied to planting new trees. Not all trees are suitable for a particular site. Many trees need ample space to grow both in crown mass and root stock. Other trees create fruit or flowers that can be a messy nuisance when those fruiting bodies fall from the tree. Still other trees do well in wet environments as others do well in dry environments. This can be a challenge when it comes to selecting the right tree for the right location.
One of the most common problems when it comes to tree selection is planting near concrete, primarily sidewalks and driveways. Some trees have very aggressive roots that are very damaging to concrete. Sweet gums, Sycamores, Poplars, and Cottonwoods are typical culprits when it comes to busted or raised sidewalks and driveways. Many municipalities post approved trees for planting trees along streets, primarily in planter strips, where sidewalks are an issue. Some lists categorize the trees into different groups based on the size planting strip available, anywhere from 3 feet to 8 foot strips. Typically, the smaller the strip the smaller the tree that can be planted.
Very few trees will do well in a 3 foot strip. This is usually only suitable for small ornamental trees like Flowering Pear, Dogwood, some Maples, and Katsura. In a 4 foot strip species like Eastern Redbud, Russian Olive, Japanese Snowbell, select Cherry, Crabapple, and Pear, and Serviceberry do well. When planting in larger strips of 6 to 8 feet, there are trees that will do well and can grow quite large at a mature age. Trees such as Oaks, Elms, Lindens, Beech, Tulip, and Zelkova can grow well in such areas. However, even with this space, concrete damage can occur with very mature trees.
The key is to give the trees ample growing space for their roots. When restricted, aggressive trees will seek out the very small space between the concrete and compacted gravel where there is water and oxygen available. The roots grow into this space and begin to expand in diameter, pushing the concrete up causing breakage and uplifting of a sidewalk or driveway. If the tree has plenty of space for growing it roots, concrete damage can be minimized.
Visit your local nursery and speak to your certified arborist ,Northwest Tree Specialists, about tree selection when is comes to planting new trees. They should have a good idea what is available and most appropriate for your specific site.



An arborist is someone who is trained in the art and science of planting, caring for and maintaining trees. ISA certification is a voluntary process where individuals can document their base of knowledge in the industry. This certification is testimony to the individual’s knowledge and ability to provide proper tree care to the customer. Acquiring this certification requires learning through experience and bookwork to be able to pass a comprehensive exam that has been developed by some of the nations leading experts in tree care. In order to maintain their certification, arborists are required to continue their education. Therefore, they are more likely to be up to date on the latest techniques in arboriculture.
