Troubleshooting
Florida Silver Palm problems — and how to fix them
Florida Silver Palm (Coccothrinax argentata) 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.
Lethal yellowing
Phytoplasma disease causing progressive frond yellowing; preventive antibiotic trunk injections are the only intervention before symptoms become severe.
Manganese deficiency
'Frizzle top' — new growth emerges stunted and necrotic; treat with soil-applied manganese sulfate in the root zone.
Root rot in clay soils
This palm is intolerant of poor drainage; plant only in sandy, well-draining soils or raised beds.
Scale insects
Treat with horticultural oil; inspect both frond surfaces and trunk closely.
Slow growth frustration
Growth is inherently slow — do not overfertilise in an attempt to speed it up, as excess salts damage roots.
