Eucalyptus trees are popular for their stunning visual appeal and distinctive aroma. However, it can be alarming to see your eucalyptus drooping, which might indicate a problem with its health. In this article, we will explore the potential causes of drooping eucalyptus leaves and provide guidance on how to address these issues effectively.

From watering habits to disease, there are many factors that can contribute to a drooping eucalyptus. As you read on, you will gain a better understanding of the conditions necessary for a thriving eucalyptus tree and the steps you can take to keep it healthy and vibrant. Dive into this informative guide and start learning about the solutions to reviving your charming eucalyptus tree today.

Causes of Eucalyptus Drooping


One reason for a drooping eucalyptus plant could be overwatering. Eucalyptus trees prefer well-draining soil and an appropriate watering schedule to thrive. Overwatering can lead to root rot, which in turn may cause the leaves to droop and yellow. To prevent this issue, be mindful of the plant’s watering needs.


Conversely, underwatering can also cause eucalyptus drooping. These trees need sufficient water, particularly during hotter months when they may require daily watering. Soil should be thoroughly damp after watering to ensure adequate hydration.

Nutrient Deficiencies

Eucalyptus plants may droop if they lack essential nutrients. Yellowing leaves can be a sign of a nutrient deficiency. To address this issue, consider adding a balanced fertilizer to replenish the soil’s nutrients and improve the plant’s overall health.


Diseases like canker, caused by a type of fungus, can make a eucalyptus tree droop. Symptoms include infected bark, yellowing leaves, and eventual branch drop as the disease progresses source. Early detection and treatment can help control the spread of the disease and may save the tree.


Lastly, pests can contribute to a drooping eucalyptus tree. Insects like aphids, borers, or scale insects can weaken the tree’s overall health, leading to drooping leaves and branches. Inspect the tree regularly for signs of infestation and treat it accordingly to protect its vitality.

Eucalyptus Care Tips


Proper watering is crucial for a healthy eucalyptus plant. Ensure that the soil is consistently moist but not soggy. To achieve this, water the plant thoroughly, then wait for the top few inches of soil to dry before watering again. Check the moisture level regularly to avoid over or under-watering.


Select a well-draining soil mix for your eucalyptus plant. A good choice is a mix of equal parts potting soil, peat moss or coco coir, and perlite or sand. This combination will promote moisture retention while providing adequate drainage, minimizing the risk of root rot.


Feed your eucalyptus plant with a balanced, water-soluble fertilizer every four to six weeks during the growing season. Using a 20-20-20 formula or similar product will provide vital nutrients to help the plant grow and thrive. Be sure to follow the manufacturer’s instructions for proper dilution and application.


Eucalyptus plants require plenty of sunlight to grow well. Position your plant in a location that receives at least 6 hours of direct sunlight per day. If natural sunlight is insufficient, supplement with artificial light from a grow light to ensure the plant’s light requirements are met.


To maintain a healthy eucalyptus plant, it is important to prune regularly. Remove any dead, damaged, or crowded branches, and trim back the tips of the plant to encourage bushy growth. Regular pruning will also help to maintain the desired shape and size of the plant and stimulate new growth.

Identifying and Treating Common Diseases

Eucalyptus trees are prone to certain diseases that may cause drooping. Two of the most common diseases affecting eucalyptus trees are canker and Phytophthora. Being able to identify and treat these diseases is essential to maintaining the health of your eucalyptus tree.

Canker: This disease, caused by a type of fungus, infects the bark of the tree and proceeds to its interior. Leaves may turn yellow and drop, and branches may also be dropped as the disease takes hold[source]. To treat canker, it is important to prune away infected branches and dispose of them properly. Applying an appropriate fungicide to the pruned areas can help prevent the spread of the disease.

Phytophthora: Phytophthora, a fungal disease that affects numerous woody plants, including eucalyptus trees (according to the source), is often referred to as root, crown, foot, or collar rot. The symptoms include wilted, yellowing leaves, stunted growth, and cankers on the trunk and stem. Proper identification and treatment are essential for the tree’s survival. Here are some measures to assist in controlling and preventing Phytophthora:

  • Improve drainage in the area to prevent waterlogging.
  • Remove any infected plant material and sterilize the tools used.
  • Apply a suitable fungicide as directed by its label.
  • Avoid overwatering and maintain a proper watering schedule.

Early intervention is key in treating any disease affecting your eucalyptus tree. By properly identifying and addressing these common issues, you can help ensure that your eucalyptus tree remains healthy and vibrant.

Controlling Pests

One potential cause of your eucalyptus drooping is due to pests infesting the plant. Some common insects such as aphids, mealybugs, and spider mites can lead to drooping as they consume the sap of the eucalyptus leaves. Before taking any measures, check for signs of pest infestations like small bugs, webbing, or discolored leaves.

There are several approaches to controlling pests on your eucalyptus plants:

  • Manual Removal: For small infestations, you can try removing insects by hand, using a soft brush or cloth to gently dislodge them from the leaves.
  • Water Spray: A strong spray of water can help remove pests like aphids and spider mites from your eucalyptus plant. Make sure to target the undersides of the leaves where pests often hide.
  • Neem Oil: Neem oil is a natural insecticide that can help control pests. Mix with water according to the package instructions and spray your eucalyptus plant thoroughly, making sure to cover all leaf surfaces. Repeat treatments as necessary.
  • Predatory Insects: Introducing beneficial insects such as ladybugs and lacewings can help reduce pest populations. These insects feed on common eucalyptus pests and can be an effective, natural solution.

Make sure to monitor your eucalyptus plant regularly for signs of pests and take action when needed. By addressing pest issues promptly, you can help prevent more severe infestations and avoid further damage to your plant that may cause it to droop.

When to Seek Professional Help

While some drooping in eucalyptus plants can be addressed with simple adjustments in care, there are times when it is best to seek professional help. In certain scenarios, the issue may be beyond the expertise or ability of a typical gardener. Below, we outline some situations where professional assistance may be necessary:

  • Severe infestations: In cases where your eucalyptus plant is dealing with a heavy pest infestation, a professional can provide targeted treatments, such as insecticides, to effectively eliminate the problem. They’ll also help with prevention measures moving forward.
  • Disease diagnosis: Not all plant diseases are easy to identify. If you suspect your eucalyptus may have a disease but are unsure of the cause, a professional can provide an accurate diagnosis and tailored treatment plan. A timely intervention could save your drooping eucalyptus.
  • Advanced Pruning: If your eucalyptus requires advanced pruning techniques like pollarding, it may be best to leave it to the experts (RHS Gardening). Professionals have the proper tools, knowledge, and experience to safely and effectively maintain your eucalyptus structure and overall health.
  • Structural problems: In some cases, drooping could be a symptom of a larger structural issue with the plant itself. A professional arborist can assess the situation and propose the best course of action to address the problem while minimizing potential damage to the eucalyptus.

Don’t hesitate to reach out to a local horticulturist or arborist if you’re uncertain about your eucalyptus plant’s needs. Their expertise can make a significant difference in ensuring the health and longevity of your tree.
