Why does your Washingtonia filifera have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyWashingtonia filifera is relatively salt-tolerant, but excessive buildup of minerals from tap water or fertilizers can cause necrosis at the leaf margins. This is particularly common when using irrigation water with high sodium or chloride content.
While these palms are drought-tolerant once established, sudden lack of moisture during heatwaves can lead to desiccation of the oldest fronds. This manifests as browning starting at the tips and moving inward.
A lack of potassium can cause chlorosis and subsequent browning of the leaf tips and margins. This is often seen in palms grown in sandy, nutrient-leached soils where frequent irrigation washes away mobile nutrients.
In extremely arid environments or during intense direct sunlight exposure without adequate humidity, the edges of the fan leaflets can dry out and turn brittle. This is essentially physical tissue damage from transpiration exceeding water uptake.
