First, you should always pay attention to your plant watering schedule. Look out for underwatering symptoms. If you are not providing the proper amount of water to your plant it needs, you will notice its leaves becoming dry & brittle.

This might be because you must identify your plant and whether it is underwatered by checking the soil moisture level. Consider sticking your finger about an inch into the soil. If the ground feels dry, it’s a sign that your plant needs to be watered.

You must regularly provide water to your eucalyptus plant, especially in summer or during hot and dry weather. It would be best to consider watering your plant until its soil becomes moist but not soaking wet. Ensure you use a well-draining potting mix and a pot with drainage holes to prevent Water pooling at the bottom.


Overwatering is another common cause of crispy eucalyptus plants. If you provide excessive water to your plant’s soil, its roots will sit in water too long, causing the eucalyptus leaves to turn yellow or brown.

Thus, it becomes crispy. If you notice any sign of Browning and yellowing of the plant leaves, you should stop watering your plant. You must only Water Your eucalyptus plant when its top inch of soil feels dry.

In addition, if you notice the water is pooling at the bottom of the pot, consider draining it and improving the drainage by adding sand and perlite to the soil mix.

Environmental Factors

Another reason why your plant might not be looking healthy or its leaves are becoming crispy could be environmental factors. Your eucalyptus plants may not receive the proper humidity & adequate temperature level.

Other than that, inadequate lighting or improper placement of the plant where it is receiving nasty light may affect its health & growth. Since you know that Eucalyptus plants thrive in warm temperatures & high humidity, consider taking the necessary action to fulfill this requirement.

Low temperatures or dry air are often responsible for leaves becoming crispy. Similarly, insufficient light can also cause your plant leaves to drop or become brittle.

To learn which type of environmental factor affects your plant, you should first check the temperature and humidity levels in the room where your plant is located. If the temperature is below 60°F or the humidity is below 40%, it’s a sign that the environment is not suitable for growing and keeping eucalyptus plants. If your plant is not receiving enough light, move it to a brighter location or supplement it with artificial light.

Pests and Diseases

Another significant reason your eucalyptus plants become crispy could be pest infestation or diseases. Many common pests may infest your eucalyptus plant if you ignore proper care, maintenance, and hygiene.

Some common problem that usually plagues plants like eucalyptus includes spider mites, mealybugs, and scale insects. Your eucalyptus plant leaves can become dry and crispy if pest infests and suck the SAP from your plant leaves.

On the other hand, many other diseases may also cause your plant leaves to become crispy, like powdery mildew and root rot. I always prefer inspecting my plants for signs of infestation and diseases. Common symptoms of pest infestation and conditions include webbing, sticky substances, spots, or discoloration.

You may also need a magnifying glass to check for tiny insects on your plant’s leaves and stems. If any of those are found, I will advise you to use insecticidal soap or a fungicide, depending on the issue.

You must also remove any dead or damaged leaves. So, never underestimate the importance of sterilizing your pruning tools between uses to prevent the spread of disease. If you don’t want to use insecticidal soap or you don’t have fungicide, you can also go with neem oil or other natural remedies to prevent pests.

Soil Issues

Do you know that soil quality can also affect the health of eucalyptus plants? According to Researchgate, eucalyptus plants prefer slightly acidic soil with a pH between 5.1 and 5.6.

If you’re growing your eucalyptus plant in soil that is too compact or lacks nutrients, your plant will not be able to absorb water & nutrients properly, leading to crispy leaves.

You should get a soil testing kit from a nearby store or online to check whether your plant is suffering from soil issues. After that, check your soil quality. Add organic matter, such as compost or aged manure, to the soil if it needs improvement. You can also use a slow-release fertilizer to give the plant nutrients. I prefer using molasses and honey mix as a sweetener and energy source for my plants during the growing season.
