Choosing the right tree for your landscape is important in the long term. Specific trees planted in the right location help avoid costly removals in the future. Want to know what to consider when choosing the perfect plants for your yard? Keep reading below for expert advice!
Consider the following when selecting a tree for your yard:
Soil conditions. While the soil varies throughout the city of Edmonton it is primarily silt loam and clay loam in texture. The PH level of the soil on the surface can vary between 6.5 to 6.8 whereas the subsurface soil has a PH of about 7.4 to 7.8.
Exposure (Sun and wind). Alberta in general has lots of days of endless sunshine. In the winter time the prevailing winds can be very cold and relentless. If you decide to plant a sensitive tree, try to plant it in a sheltered spot.
Drainage. The soil in the Edmonton area typically does not drain well especially with our clay subsoil. Pay attention to low spots on your property as water usually drains towards the low spot and becomes stagnant. If drainage is an issue ask the staff at a reputable garden center for a tree that does well in areas of poor drainage.
Space constraints. Before you purchase a tree make sure you understand how big the tree will grow. You can ask the staff at your local garden center for your desired trees “mature height” and “mature spread”. I will include a quick guide of some of my favorite trees to help you determine the right size for your yard.
Hardiness zone. Edmonton is located in zone 3b What that means is that our minimum temperature in the winter is around 37.2 to 34.5C You can use this guide to help determine what trees and plants will grow best in your area. Buying plants with a zone hardiness from 0 to 3 will work well in your yard.
Insect and disease susceptibility. There are many trees with issues associated with each particular species. While it's hard to find a tree that will be completely disease free, however most trees can live a long and happy life while having some minor ailments. I have many clients that are in love with their trees despite requiring regular health check ups. Some trees require more maintenance than others. Again it's good to consult an expert before selecting your new tree.

Consult an expert! If you are unsure of what to plant you are not alone. It is a decision that you will have to live with for a long time. My best recommendation before buying a tree for your yard is to visit a local garden center and ask the experts. Give them as much information about your yard as possible. Whether you want to plant on a slope in poor soil or in an exposed location they can help you decide on the right tree.
