When seeing tree leaves curling up on the trees around your property, these plants are likely experiencing environmental stresses. Our experts for tree services in Fortuna, CA, can do an inspection to determine exactly what problems are occurring. Learn more about diagnosing this issue and what steps can alleviate it.

Too Much or Too Little Water Can Cause Curled Leaves
Drought stress is a common reason why you see leaves curling. When your property goes for a long time without rain, you might need to perform deep watering for the trees to combat the drought. Leaf brittleness or wrinkling can be another sign of a lack of water.
During extremely rainy weather, you might also see leaf curling. The entire tree might look like it’s drooping when the soil has too much water.
Our arborists can visit your property and do tests to determine whether either of these problems is occurring.
Environmental Issues Place Stress on Trees
Trees shedding leaves is normal during the dormant season. However, with tree leaves curling up or dropping well before the plant goes into dormancy, you may have environmental issues occurring. Such items could include:
- Heat stress in summer
- Nutrient deficiency
- Lack of sunlight
- Poor air movement
- Extremely dusty conditions
If you have a lot of trees planted in the same area, for example, the other canopies might block airflow and sunlight. The tree with problems with leaf curling might benefit from trimming the larger, overgrown trees that block air and sun. An assessment from our arborists can determine the safest way to maintain the health of each tree during trimming.
Insects and Fungal Infections Can Harm Leaf Health
A fungal infection is dangerous for the health of trees, leading to multiple issues, including leaf curls. If you also see other signs of disease, such as rust spots or oozing growths on branches, contact us for treatment.
An aphid infestation could be the cause of the curling you’re seeing. As the insects feed on the nutrients meant for the leaves, they may end up curling and suffering damage. Generally, letting our experts safely eliminate the insects as soon as you notice them allows the plant to eventually return to health.
Over-Spraying of Herbicides is Dangerous
Herbicide damage is a common reason for leaf curling on your trees. If you are spraying for weeds in a nearby area on a windy day, the liquid herbicide can settle on the leaves. The chemicals can damage the health of the tree without immediate intervention from our professionals.
