Which Tree Should I Choose?
The key to a healthy tree starts with selecting the right tree for the site conditions. For each of the trees in our free tree program, we describe its preferred light and soil conditions. You also want to make sure that as the tree grows its canopy and roots won't cause trouble to buildings, infrastructure, or below-ground utilities.
Aesthetics & Function
Do you want a tree to perform a specific function?
- Evergreen trees provide privacy, wind break, and shading all year round.
- Deciduous trees can provide shade in the summer and let through the winter sun when they lose their leaves.
- Evergreen trees are green and full all year round.
- Deciduous trees can provide interesting fall colors, or seasonal flowers.
Size and Form
- Choose a size and shape that makes sense for the location.
- Make sure the tree's mature height and canopy spread will not interfere with the surrounding buildings, power lines, fences, etc., as shown in the diagram above.
- The roots will grow at least as wide as the canopy, and remain close to the surface, so avoid planting close to pavement and building foundations.
Light
Here are the different classifications of light requirements for trees:
 |
Full sun means 6 or more hours of direct sun. Usually this describes a south or southwesterly site with little to no shade at any time of the day from either trees or a structure. |
 |
Part sun means four to six hours of direct sun per day, not necessarily consecutive hours. It will generally do better with more afternoon sun, especially if its a flowering tree. |
 |
Part shade also means four to six hours of direct sun per day but most of that sunlight should come in the morning hours, when the sun’s intensity is lower. |
 |
Full shade means less than four hours of direct sun per day. It can also mean dappled light below a larger tree. |
Soil & Moisture
Your tree will do best if the soil type and moisture level is compatible with what it likes. Some trees like dry well-drained soil and some prefer moist water-retaining soil. Some trees are flexible and can tolerate a wide range. Our tree catalog provides this information on each tree.
