Quaking Aspen: pruning, storm risk and removal
Populus tremuloides. Also called Trembling aspen, Golden aspen, Popple.
Plain-English notes for homeowners, plus field notes for tree crews. General guidance only: for one specific tree, have a local insured pro look at it.
Quaking Aspen at a glance
| Height | 40-60 ft |
|---|---|
| Spread | 20-30 ft |
| Growth rate | Fast |
| USDA zones | 1-6 |
| Lifespan | typically 40-80 years for a single trunk, though the root system of a colony can be much older |
| Type | Deciduous |
| Native range | The most widely spread native tree in North America. It grows in cool northern forests and in the mountains of the West, from Alaska and Canada to the Rockies and Southwest highlands. |
| Roots | Shallow and wide-spreading. It sends up many root suckers, so one tree becomes a group of stems that share a root system. |
| Wood | Soft, light and low in strength. It is used for pulp, pallets and strand board. As firewood it gives low to moderate heat and burns quickly. |
| Storm risk | mediumThe wood is soft and weak. Trunks are short-lived and often decayed inside, so branches and whole stems can break in wind or snow. |
Typical ranges, not guarantees. Soil, water, space and care change how a tree grows. Storm risk is our general rating for the species, not an inspection.
For homeowners
Caring for a quaking aspen
Best time to prune
Prune in late winter or in summer, and keep cuts small. Remove dead, diseased or rubbing branches. Cut suckers off where they are not wanted.
Avoid pruning
Avoid large cuts and wounding the bark, which opens the way to canker fungi and decay. Avoid pruning during wet spring weather.
More on timing: when to prune trees.
- Aspen sends up suckers in the lawn, sometimes many feet from the trunk. Plan for this before you plant.
- Keep it away from septic lines, pipes and pavement because of its spreading shallow roots.
- Dark, sunken patches or oozing on the trunk are typically signs of canker disease.
- Aspen does poorly in hot, dry places at low elevations. Dieback is common there.
Safety first
Do not climb a tree or use a chainsaw on storm-loaded or broken wood. If a tree or limb is touching power lines, stay away and call the utility. If someone is in danger, call 911. For anything big, hire a local insured pro: read how to hire a tree service and is my tree dangerous?

For tree crews
Field notes: working on quaking aspen
- 1Soft wood and common internal decay mean you should assess stems carefully before climbing.
- 2Stump grinding alone often does not stop suckers. Tell the customer to expect regrowth.
- 3Chip and haul volume is high because stems are multiple. Quote for the full clump.
- 4Bark wounds from equipment heal slowly. Protect trees that stay.
Removal notes
Cutting down one stem often sends up a thicket of suckers. Stump treatment by a licensed pro may be needed to stop regrowth. Old stems are often hollow or soft inside, so check before climbing or rigging.
Wood
Soft, light and low in strength. It is used for pulp, pallets and strand board. As firewood it gives low to moderate heat and burns quickly.

Quaking Aspen: common questions
Why does my aspen keep sending up new trees?
Aspen spreads by root suckers. When a stem is cut or damaged, the roots send up many new shoots. This is how aspen colonies grow. Removing the whole tree may not end it.
Why are the leaves on an aspen always moving?
The leaf stems are flat and long, so the leaves flutter in even a light breeze. That is where the name quaking comes from.
How can I stop aspen suckers?
Mowing or cutting the shoots repeatedly can wear the root system down over time. For heavy infestations, ask a licensed pro about stump and sucker treatments. Follow local rules and label directions.
Why is my aspen dying back?
Common causes are drought stress, canker diseases, borers and root problems. Aspen outside its cool mountain or northern range often struggles in heat. A certified arborist can check the cause.
Is aspen a good tree for a yard?
It gives fast shade and nice fall color, but it is short-lived, drops limbs and suckers heavily. Many homeowners prefer longer-lived trees near houses.
Is aspen good firewood?
It is fair at best. It burns quickly and gives less heat than oak or hickory. It is easy to split and dries fast.
