Why do aspens quiver?
The tremble, shimmer, and quake of aspen leaves are the product of how the leaves are structured. The petiole, the stalk which attaches a leaf blade to its stem, is flat on aspen leaves, allowing the petiole to act as a pivot on which the leaves can easily move, in response to even the mildest breeze.
Why do aspen trees tremble?
The leaf stalk is flattened and longer than the leaf blade, and the slightest breeze causes the leaves to flutter.
How do you stop a quaking aspen?
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.
Do aspen trees shake?
The long and very flattened leaf stalks result in the Aspen having a rather unique characteristic: the leaf blades flutter, tremble, shiver and quake in the slightest breeze.
Why do aspen leaves quiver?
In the case of the aspen, the petiole is flat, instead of the usual round. So instead of the flat leaf and stem being in the same plane, the flat petiole is attached at a 90-degree angle to the flat leaf. That causes the leaf’s trembling movement.
Are quaking aspen good trees?
Some gardeners love them, some do not. Aspen trees grow very quickly and are very hardy. That means that you can “furnish” a new backyard in just a few seasons if you plant aspens. Aspens are small and won’t overwhelm your yard, and sometimes they provide nice autumn color.

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.
Do aspen trees have deep roots?
Aspens have shallow roots and they only penetrate the soil up to a distance of 12 inches.
What eats a quaking aspen?

Why do aspen trees bend over?
Tree Damage From Winter Snow and Ice. Branches, both large and small, are naturally flexible, allowing trees and shrubs to bend and move with winter winds and the weight of snow and ice.
How do aspen trees respond to fire?
Although aspen forests do not burn readily, aspen trees are extremely sensitive to fire. A fire intense enough to kill the aspen overstory will stimulate abundant suckering, though some suckers arise after any fire. As many as 50,000 to 100,000 suckers can sprout and grow on a single acre after a fire.
Why do aspens grow after fire?
Following fire, aspen clones (genets) exploit newly available light and nutrient resources to regenerate via vegetative sprouting or “suckering” from lateral roots. The amount of tree (ramet) regeneration depends on several factors including pre-fire stand conditions, fire severity, climate, and post-fire browsing.
Is aspen a climax species?
The aspen, a sub-climax species in our forest on the north rim, is just one of several steps of plant succession in the natural reforestation of burnt over areas in this region.
Are aspen trees connected underground?
From afar, a forest of aspen trees is a wonder to behold. Dig a little deeper, and you’ll find something even more fascinating: Every single one of the aspen trees in a grove is connected as a single living organism. Aspen trees have a complex underground root system from which each individual tree sprouts and grows.
