Did you know that citrus trees may get yellow leaves for different reasons? It might not be getting enough nutrients, too little or too much water, or have diseases.
In this episode, Dr Stephan Verreynne, advisory manager at AECI Plant Health, looks into why citrus leaves may turn yellow and what farmers can do.
Verreynne explains, “There may be several causes of yellow leaves on citrus trees. The most common causes are nutrient deficiencies, soil moisture status, diseases, and other factors such as saline conditions in soil and water, and leaf age.”

Non-nutrient-related causes of leaves turning yellow are also discussed.
“Too little water will rarely cause yellow leaves, but reduced uptake of nutrients may cause deficiencies that will lead to yellow leaves. Too little water may cause little new growth or poor growth. Too much water can be a bigger problem,” he explains.
Furthermore, over-irrigation pushes the oxygen out of the soil profile. Verreynne says without oxygen, root uptake of nutrients is reduced, which may lead to yellow leaves. The oxygen deficiency in the root zone puts trees under stress making them more susceptible to root diseases, like root and collar rot as well as nematodes.
In this episode, he also discusses:
- Trees with phytophthora root rot;
- Extreme saline conditions;
- Citrus leaves lifespan and more.
