watering

Watering American aspen (Populus tremuloides) is most effective when done 1 to 2 times a week. Each session should involve thoroughly soaking the soil around the tree to a depth of 6 inches, making sure to guarantee sufficient moisture for the roots. If the soil in the tree's area appears dry, increase watering frequency. During hot, dry spells, it is best to provide more frequent, shallow watering around the base of the tree. This method allows for a larger amount of roots to be reached and ensures that the tree gets the water it needs.

sunlight

American Aspen trees (Populus tremuloides) thrive in full sunlight. They require a minimum of 6 to 7 hours of sunlight each day in order to grow and thrive. During the fall and winter months, sunlight exposure may be reduced to as little as 4 hours due to the shorter daylight hours. During the spring and summer months, however, American Aspens should receive at least 8 to 9 hours of sunlight to ensure proper growth. Additionally, American Aspens require full sun during the growing season to produce optimal growth.

pruning

For American aspen, pruning should be done once per year, preferably in late spring after the leaves have fully developed. Pruning should be done to remove branches that are dead, diseased, or damaged, as well as to thin out overcrowded growth and shape the canopy into an aesthetically pleasing form. When pruning, the lower branches should be maintained as much as possible. Cut only branches that are at least 2/3s of their diameter diameter. Keep the shape of the canopy as natural as possible, taking care not to create a dome-shaped crown or ‘lion's tail’. Excessive pruning can create instability in the tree and should be avoided.
