Troubleshooting
Mexican Blue Palm problems — and how to fix them
Mexican Blue Palm (Brahea armata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and crown rot from overwatering
This desert palm rots quickly in wet or poorly drained soil. Plant in sharply draining ground and water sparingly, especially in cool or wet weather.
Loss of blue colour
In shade or with too much shelter the silver-blue fades and the crown thins. Grow in full, strong sun to keep the powder-blue waxy bloom.
Fungal leaf spot
Humid, wet conditions cause dark frond spotting on this arid-adapted palm. Improve airflow, avoid overhead watering, and remove affected fronds.
Frost damage to fronds
Hard or wet frost can scorch fronds and damage the bud. Keep conditions dry in winter and protect young plants in severe cold.
