Podocarpus, often referred to as the “Yellowwood” or “Yew Pine,” is an evergreen conifer native to subtropical and tropical regions. Known for their lush foliage and low maintenance requirements, these trees are popular choices for landscaping and horticultural enthusiasts.
However, one of the lesser-known aspects of Podocarpus is the occasional leaf drop that occurs during the fall season. In this blog post, we will delve into the reasons behind this phenomenon, offer suggestions for prevention, and provide a comprehensive guide to caring for your Podocarpus during this transitional period.

Causes of Podocarpus Leaves Dropping in Fall
- Natural Leaf Drop: Though Podocarpus is an evergreen tree, it’s not uncommon for it to shed some of its leaves during the fall season. As the tree grows, older leaves lose their efficiency and are replaced by new growth. In this case, the leaf drop is a natural part of the tree’s life cycle and shouldn’t be a cause for concern.
- Environmental Stress: Various environmental factors can stress Podocarpus trees and cause them to drop leaves prematurely. These may include sudden changes in temperature, drought, inadequate sunlight, or poor soil conditions. Under stress, the tree may shed leaves to conserve resources and ensure its survival.
- Pests and Diseases: Podocarpus trees can be susceptible to pests and diseases that may lead to leaf drop. Common culprits include scale insects, aphids, and fungal infections. In these instances, the tree sheds its infected leaves in an attempt to combat the issue and prevent further damage.

Prevention and Care
Podocarpus, also known as the yew pine, is an evergreen tree or shrub that belongs to the Podocarpaceae family. Although it is an evergreen plant, it is normal for Podocarpus to shed some of its leaves in the fall season.
This is a natural process, as the plant is shedding its older leaves to make way for new growth. However, if the leaf drop is excessive, it could be a sign of stress or an underlying issue with the plant.
Here are some factors that could cause excessive leaf drop in Podocarpus plants and how to prevent and care for them:
- Watering: Podocarpus plants prefer well-drained soil and can be sensitive to both overwatering and underwatering. Ensure that your plant receives consistent moisture but is not sitting in soggy soil. Allow the top inch of the soil to dry out between waterings.
- Temperature and humidity: Podocarpus plants are sensitive to extreme temperature fluctuations. They prefer temperatures between 60°F to 75°F (15°C to 24°C) and moderate humidity levels. To maintain consistent temperature and humidity, avoid placing the plant near heating vents or in drafty areas.
- Light: These plants require bright, indirect sunlight to thrive. Insufficient light could cause stress, leading to leaf drop. If your plant is indoors, ensure it is placed near a window that receives plenty of natural light. If it is outdoors, plant it in a location that provides dappled sunlight or morning sun and afternoon shade.
- Fertilization: Podocarpus plants require a balanced, slow-release fertilizer to support healthy growth. Over-fertilization can cause leaf burn and leaf drop. Apply fertilizer according to the package instructions, typically once in the spring and again in mid-summer.
- Pests and diseases: Leaf drop can also be caused by pests like aphids, scale insects, or spider mites, as well as fungal diseases like root rot. Inspect the plant regularly for signs of infestation or disease and treat promptly with appropriate measures like insecticidal soap, neem oil, or fungicides.
- Transplant shock: Transplanting a Podocarpus plant can cause stress and lead to leaf drop. To minimize shock, transplant in the early spring or fall, when temperatures are mild, and be gentle with the root system.
By addressing these factors and providing the proper care, you can help prevent excessive leaf drop in your Podocarpus plant and ensure its overall health and well-being.

Q. Why do Podocarpus leaves drop in the fall?
A. Podocarpus leaves can drop in the fall as part of their natural growth cycle. This process, known as leaf abscission, is the plant’s way of conserving resources during the colder months.
Additionally, environmental factors such as temperature, humidity, and watering habits can also contribute to leaf drop.
Q. Is it normal for Podocarpus to lose leaves during the fall season?
A. Yes, it is normal for Podocarpus to lose some leaves during the fall season. This is a natural part of the plant’s growth cycle, which helps it conserve energy and resources in preparation for winter.
However, if you notice an excessive amount of leaf drop, it could be due to factors such as stress or poor care.
Q. How can I prevent excessive leaf drop in my Podocarpus plant during the fall?
A. To prevent excessive leaf drop, ensure your Podocarpus receives proper care, including adequate light, well-draining soil, and consistent watering.
Avoid sudden temperature changes and protect your plant from cold drafts. Regularly inspect your plant for pests and diseases, as these can also cause leaf drop.
Q. How do I know if my Podocarpus plant’s leaf drop is due to natural seasonal change or an underlying issue?
A moderate amount of leaf drop during the fall season is normal for Podocarpus plants. However, if you notice excessive leaf drop or the plant appears unhealthy, consider evaluating its care and environment. Check for signs of pests, diseases, or stress, such as yellowing leaves, wilted stems, or weak growth.
Q. Can I propagate the dropped leaves of my Podocarpus plant during the fall?
A. While Podocarpus plants can be propagated from cuttings, the dropped leaves during fall may not be the best choice.
It’s better to use fresh, healthy cuttings taken during the growing season, preferably spring or early summer, for the highest chance of successful propagation.
