Overview
What Yellowing Leaves May Mean
Yellowing leaves are often an early sign that a tree or shrub is under stress. Sometimes the issue is temporary and tied to moisture or environmental conditions. In other situations, yellowing can point to nutrient deficiency, root problems, disease, or insect pressure.
Because yellowing can happen for several reasons, it helps to look at where it is occurring, how quickly it is spreading, and whether there are other symptoms present.

Root Cause
Possible Causes
Yellowing leaves may be caused by:
- Drought or heat stress
- Overwatering
- Poor drainage
- Root damage
- Nutrient deficiency
- Chlorosis
- Certain disease issues
- Insect Feeding
Different causes can create similar-looking browning, which is why appearance alone does not always tell the full story.
Plants at Risk
Trees & Shrubs Commonly Affected
Yellowing can appear on a wide range of landscape plants, including maple, oak, crabapple, ornamental trees, evergreens, and foundation shrubs. Some species are especially prone to chlorosis or stress-related yellowing in difficult soil conditions.

Red Flags
When to Be Concerned
A little seasonal yellowing is not always a major problem. But when the symptom becomes widespread, shows up repeatedly, or is paired with stunted growth or canopy thinning, it may signal that the plant’s health is being compromised.
It is smart to act early if multiple plants are showing the same symptom or if a mature tree is losing vigor.

Common Questions
Frequently Asked Questions
Why are my tree leaves turning yellow?
Yellowing leaves can be tied to moisture imbalance, nutrient issues, poor soil conditions, root stress, insects, or disease. The exact cause depends on the plant and the symptom pattern.
Does yellowing always mean a nutrient problem?
No. Nutrient deficiency is one possibility, but yellowing can also be caused by watering issues, root damage, chlorosis, insects, or disease-related stress.
Can yellow leaves turn green again?
Sometimes new growth can improve once the cause is addressed, but leaves that are already heavily yellowed may not fully recover.
What should I do if multiple plants are turning yellow?
When several plants show the same symptom, it may point to a site-wide issue such as drainage, soil conditions, or weather stress. That is a good time to schedule an evaluation.
