I've got a property with a dozen queen palms and sabals in the lawn.

Palm Fertilizer: Use a palm-specific granular fertilizer with an analysis close to 8-2-12-4Mg (N-P-K-Mg) plus micronutrients (Mn, Fe, Zn, Cu, B).

• Why: Palms have high K and Mg demands; turf fertilizers are high-N, low-K/Mg and lack critical micros. Deficiencies (frizzle top, lethal yellowing look-alikes) are expensive to correct.
• Rate: 1.5 lb per 100 ft² of canopy area (≈ 5–8 lb per mature queen/sabal).
• Timing: 3×/yr (Mar, Jun, Sep) in FL; 2×/yr (spring, early summer) farther north. Broadcast under canopy, keep 1 ft off trunk, water in.

Lawn Fertilizer Conflict:

• Yes, it matters. Standard turf programs (e.g., 16-4-8, 29-0-4) push excess N and negligible K/Mg. This induces K/Mg deficiency in nearby palms and can trigger ganoderma butt rot via excessive succulent growth.
• Action: Tell the lawn company “No fertilizer within 25 ft of palm trunks.” Flag the zone. If they must fertilize the grass there, require a palm-safe blend (same 8-2-12-4Mg) at turf rate.

Code/Standard: UF/IFAS SL-279; ANSI A300 Part 2 (soil management). Safety: Wear gloves, dust mask. Keep granules off hardscapes to prevent staining/runoff.

For queen palms (Syagrus romanzoffiana) and sabal palms (Sabal palmetto), use a palm-specific fertilizer with a balanced NPK ratio (e.g., 8-2-12 or 10-5-15) plus essential micronutrients: magnesium (Mg), manganese (Mn), iron (Fe), and boron (B). Look for formulations labeled for palms with controlled-release nitrogen and water-soluble micronutrients (e.g., sulfate or chelated forms). Apply 1.5 lbs of actual nitrogen per 1,000 sq ft of canopy area, 3–4 times per year (spring through early fall), avoiding winter dormancy.

Yes, it matters what the lawn guy is putting on the turf. Many lawn fertilizers are high in nitrogen and low in potassium/micronutrients — exactly what palms don’t need. Excessive turf N can promote weak, leggy palm growth and exacerbate micronutrient deficiencies (especially K and Mg), leading to frizzle top (Mn deficiency) or chlorosis. Avoid "weed and feed" products near palms — herbicides like 2,4-D can harm palms.

Best practice:

• Keep turf fertilization at least 2–3 ft from palm trunks.
• Use separate applications: palm fertilizer under the canopy, turf fertilizer limited to grass areas.
• Test soil every 2–3 years for pH and nutrients (palms prefer pH 6.0–6.5).
• If deficiency symptoms appear (yellowing, frizzled fronds), supplement with manganese sulfate or magnesium sulfate (Epsom salt) as needed.

If unsure, consult a certified arborist or local extension office (UF/IFAS for FL palms). Never guess — palm nutrition is precise. (Reference: UF/IFAS ENH1009, "Fertilization of Palms in the Landscape")
