NOTE: The terms Quaking aspen and Populus tremuloides are identical in this text; in reality, Populus tremuloides is Quaking aspen’s biological word.
The quaking aspen is a tree in the willow family that has a name that refers to how its leaves tremble at the slightest breeze. The fall color of aspen is referred to as golden aspen, bark color is white aspen, or a favorite habitat is mountain aspen. It’s easy to identify it by its smooth, light-colored bark, which is interrupted at intervals by darker knots and horizontal scars.
It has a flattened leafstalks, which cause the leaves to “quake” when the wind blows. The leaves are 3 inches across and rounded. A catkin is the flower/seedhead. If you want to grow quaking aspen, the best time to do so is after the last frost date in your area.

Why are my Quaking aspen leaves turning yellow?
This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some indicators of yellowing on the Populus tremuloides brought on by its numerous flaws:
- Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- A lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my Quaking aspen sunburned?
It is simple to determine whether your Quaking aspen (your Populus tremuloides) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, the leaves of your Quaking aspen can also change color if it receives too much water or insufficient light.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Most of the time, leaves of a Quaking aspen that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Populus tremuloides in direct sunlight?
No! If your Populus tremuloides (or Quaking aspen) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Quaking aspen is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Quaking aspen out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Populus tremuloides leaves drooping or wilting ?
This typically occurs when your Populus tremuloides gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
Whether your Populus tremuloides plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Quaking aspen right after a dry period thinking that it needs a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Populus tremuloides
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Populus tremuloides.
The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.
Always keep temperatures stable
Maintaining a consistent temperature for your Populus tremuloides is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Populus tremuloides close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Quaking aspen Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
For your Quaking aspen, this would be a true descent into hell, and it would also appease the pests.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
