Ponytail Palm Leaves Turning Yellow: 8 Causes & Top Tips

If you’re unsure what to do about ponytail palm leaves turning yellow, this is the guide for you.

Ponytail palm leaves will typically turn yellow due to problems with watering or other issues like a lack of humidity or too much direct sunlight.

In my experience, you must act quickly if several leaves start turning yellow, as it’s a sign that something is wrong with your plant.

Keep reading to learn the eight most common causes of ponytail palm leaves turning yellow, with tips for preventing it in the future.

8 Causes Of Yellow Leaves On Ponytail Palms

Here are the eight most common reasons for yellow leaves on ponytail palms that I’ve noticed over the years.

1. Overwatering

Overwatering is probably the most common reason for ponytail palm leaves turning yellow.

Ponytail palms don’t require a lot of water because they can store so much in their stem, and because of this, they prefer well-draining soil that is moist but not saturated with water.

When the soil is constantly wet, it suffocates the roots and makes it more difficult for moisture and nutrients to reach the leaves, thus turning them yellow.

Overwatered conditions can also quickly lead to root rot, as suffocated roots die, and also due to fungi favored in overwatered conditions.

2. Underwatering

Underwatering can also lead to yellowing leaves, as ponytail palms still require some water.

Underwatered leaves will turn dry and crispy due to a lack of moisture, and during this time, they will turn yellow and brown shortly after.

Brown tips are also a very common symptom.

3. Pests

Pest infestations on ponytail palms can lead to yellowing leaves and many other symptoms – even death in severe cases.

Luckily ponytail palms aren’t prone to lots of insects, but mealybugs or scale can be a problem.

These pests feed on the sap in the leaves, causing severe damage to the leaves and turning them yellow/brown (in patches) in the process.

Both pests should be visible to the eye and are often found on the underside of leaves.

They will also leave behind a honeydew residue, which is another telltale sign that pests are the problem.

4. Diseases

Diseases like root and stem rot can cause your ponytail palm’s leaves to turn yellow.

These types of disease are often caused by overwatering, which leads to root rot and eventually stem rot.

Other diseases like sooty mold and botrytis blight can also affect ponytail palms.

Sooty mold grows on honeydew left behind by pests like mealybugs and scale, and botyris blight is spread through excessive moisture (this is why misting your ponytail palm is a bad idea).

5. Sunlight

Insufficient or excessive sunlight can negatively impact your ponytail palm, causing yellow leaves:

  • Too Much Sunlight – Certain ponytail palms, especially those kept indoors, are sensitive to excessive direct sunlight. It can quickly scorch the leaves, leading to irregular yellow and brown spots on the leaves.
  • Not Enough Sunlight – A lack of sunlight will also hurt your ponytail palm, as it is crucial for photosynthesis. Without enough sunlight, the growth rate will slow down significantly, and the leaves will droop and eventually turn yellow and brown as they die.

Ponytail palms prefer bright, indirect light, so ensure that you position your plant in a suitable location with the right amount of light to support its growth.

6. Humidity

Ponytail Palms can tolerate various humidity levels, but consistently low or high humidity levels can stress the plant, leading to yellow leaves:

  • Low Humidity – If the humidity is very low, it will dry out the leaves, resulting in brown tips and yellowing.
  • High Humidity – High humidity creates an environment prone to pest infestations and diseases. High humidity attracts pests, and excess moisture on the leaves or soil can quickly lead to root rot, stem rot, or other disease.

Humidity around 40-50% is ideal for ponytail palms.

7. Temperature

Ponytail palms are native to southeastern Mexico and therefore adapted to warm conditions.

Temperature fluctuations or exposure to temperatures consistently below 50 degrees Fahrenheit can stress your ponytail palm and result in yellow leaves.

Avoid moving your ponytail palm into a location with drastically different temperatures, and avoid cold temperatures to keep the leaves healthy.

8. Nutrient Deficiencies Or Excess

Yellow leaves can also be a result of a lack of nutrients or an excess:

  • Nutrient Deficiency – Certain nutrients like nitrogen are extremely valuable to leaf development and growth. A lack of nutrients – not only nitrogen but others like phosphorus as well – can lead to yellowing and wilting leaves as well as slow overall growth.
  • Excess Fertilizer (learn more here)- This can scorch the roots, leading to similar symptoms to root rot, including yellow and wilting leaves.

Consider using a balanced fertilizer to replenish these nutrients, following the recommended dosage instructions.

Remember not to over-fertilize, as it can cause more harm than good.

How To Prevent Yellow Leaves On Ponytail Palms

There’s no denying that it’s much easier to prevent yellow leaves in the first place, especially since they can be a sign of something much worse, like root rot.

Here are some easy tips for keeping your ponytail palm healthy and happy, based on my years of experience keeping this plant.

Choosing The Right Soil & Use Drainage Holes

Selecting the appropriate soil for your ponytail palm is crucial for its growth and health.

A good soil mix will provide the necessary nutrients for leaf growth and help reduce the likelihood of overwatering.

A well-draining, sandy, and loamy soil is recommended since this plant is native to the desert.

Cactus or succulent potting mixes are ideal for ponytail palms as they drain well but hold on to sufficient moisture.

If you prefer a homemade version, you can use equal parts of potting soil, perlite, and sand.

Don’t forget to have drainage holes as well, which allow excess water to escape through the bottom rather than potentially suffocating the roots.

Proper Watering Techniques

Overwatering will lead to yellowing leaves and, eventually, root rot, so watering your ponytail palm properly is important.

I like to water my palms when the top inch of soil dries out, and this seem to work very well.


If you’re using the right type of soil, it should be packed full of nutrients.

Fertilizing is a great way to boost the nutrient profile and overall health of your ponytail palm, however.

I like to fertilize once per month during spring and summer with a complete liquid fertilizer, and I’ve noticed great growth from this.

Don’t get carried away with fertilizing, though, as you can easily scorch the roots if you use too much.

Pest Management

Pests such as spider mites and mealybugs can cause damage to your ponytail palm, resulting in yellowing leaves.

Regularly inspect your plant for any signs of pest infestation and take immediate action if needed.

If you notice many pests on your ponytail palm leaves, use an insecticide to remove them. Small infestations can be dealt with by rinsing the leaves with water.

Disease Control

Diseases like root rot or stem rot will require reporting, which we will cover shortly.

Other diseases that affect the leaves specifically, like sooty mold, will require pruning of affected leaves, dealing with the root cause (getting rid of the pests), and treating the remaining leaves with fungicide.

What To Do If Several Leaves Start Turning Yellow

If several leaves of your ponytail palm start to turn yellow quickly, you need to take action.

Follow the steps below to get your plant back to health:


The first step is to repot your ponytail palm.

This has several benefits:

  • It lets you inspect the roots for signs of rot or overwatering.
  • Replacing the soil boosts the nutrient content and makes sure it is well-draining.

Carefully remove the palm from its current pot, gently shaking off excess soil from the roots.

Trim any mushy, decaying roots, and treat the rest of the roots with fungicide. When repotting, follow these guidelines:

  • Choose a pot with drainage holes to prevent waterlogging.
  • Use a well-draining potting mix, such as cactus or succulent soil.
  • Select a pot only slightly larger than the previous one to avoid overwatering.

Once you’ve repotted, water the soil so it is moist, and place your plant in an area with bright, indirect sunlight and appropriate temperature/humidity.


After repotting, you can prune any yellow leaves.

Here are a few tips for the process:

  • Cut as close to the trunk as possible without damaging it.
  • Remove only affected leaves, leaving healthy green ones intact.
  • Keep your tools clean to prevent the spreading of diseases or pests.

After repotting and pruning, your ponytail palm may take a while to adjust to its new soil.

Give it a week or two; there should be signs of new leaf growth. If the remaining leaves start to turn yellow, an outside factor is likely to blame, such as sunlight or humidity.

In Summary

Hopefully, this article has covered everything there is to know about ponytail palm leaves turning yellow.

In most cases, yellow leaves are not something to stress about and require optimizing an existing condition, such as sunlight or humidity.

In more severe cases, repotting will be necessary to protect the roots and stem.
