How long do big tooth aspen live?
Bigtooth aspen is a rapidly growing tree. At maturity, it attains heights of 60 to 80 feet (18-24 m) and diameters at breast height of 8 to 10 inches (20-25 cm). Stands begin to deteriorate after 50 to 70 years on good sites, but individuals may live as long as 100 years .
What does a Bigtooth aspen tree look like?

What kills aspen trees?
The right way to remove aspen is to kill the tree and the root system with an herbicide and cut it down after it is dead. To kill aspens apply the herbicide Roundup to the base of the trunk. Drill a series of holes into the trunk at a 45 degree angle and fill the holes with concentrated herbicide.
What is special about Aspen trees?
Aspen is noted for its ability to regenerate vegetatively by shoots and suckers arising along its long lateral roots. Root sprouting results in many genetically identical trees, in aggregate called a “clone”. All the trees in a clone have identical characteristics and share a root structure.
How can you tell if you have a big tooth aspen?
Bigtooth aspen can be distinguished from quaking aspen by the smaller number and the larger size of the teeth on the leaves and from the lighter colored buds. Bigtooth aspen is a short lived (50 years), fast growing, medium sized tree. It seldom exceeds 60 feet in height and 20 inches in diameter.
Why are they called Quaking Aspen?
Quaking aspens, also called trembling aspens, are named for their leaves. Flat leaves attach to branches with lengthy stalks called petioles, which quake or tremble in light breezes. Quaking aspens regularly grow in dense, pure stands, creating a stunning golden vista when their leaves change color in the fall.
What is the difference between birch and aspen trees?

What is the average lifespan of an aspen tree?
The lifespan of quaking aspens is unique. Individual quaking aspen stems usually live for about 50 to 60 years, sometimes up to 150 years in the West. However, in many cases, each tree is actually part of a much larger organism, since multiple stems can sprout from the same root system.
Can you overwater aspen trees?
Aspen aren’t terribly drough-tolerant trees so watering regularly is a must. However, they can be overwatered just like everything else. Also, take a close look at the trunk of the tree from the soil line up past the first several branches.
Is aspen the same as birch?
Although aspen are somewhat similar in appearance to some species of birch, birch trees belong to an entirely different family of trees. Whereas aspen leaves are perfectly flat, birch leaves are slightly “V” shaped and more elongated than Quaking Aspen leaves.
