Boron Deficiency in Palms
Commonly affects: Various palms (Arecaceae)
New fronds emerge stunted, twisted, or with a distinctive accordion-like pleating, and in severe cases the growing point fails entirely.
Potential Causes
- 1Boron deficiency, relatively uncommon but serious when it occurs, often linked to soil conditions or leaching in heavy rainfall areas
- 2Excessive fertilisation with high-nitrogen products that can worsen an existing marginal boron deficiency
- 3New growth being affected specifically, since boron is critical for proper cell development in expanding tissue
Solution Steps
- 1Apply a boron supplement specifically formulated and dosed for palms, since over-application of boron is toxic and the margin for correct dosing is narrow
- 2Consult a professional or soil test before applying, given how easy it is to over-correct
- 3Address any drainage issues that might be leaching boron from the root zone
- 4Monitor new growth closely for improvement, since correction can take multiple growth cycles to show clearly
Prevention Tip
Boron deficiency correction requires care, since the difference between a corrective dose and a toxic one for palms is narrow â a soil test before treating is worthwhile.
