Robellini Palms Near Pool Declining: Chemical Exposure or Root Stress?

Two pygmy date palms (Robellini) at pool entry droopy, yellow; others fine. Dog enters/exits there. Pool low chlorine + cartridge chemicals. White granular on fronds = normal (tomentum).

Likely Causes

• Chemical splash/drift from pool—chlorine, algaecides, pH adjusters.
• Dog urine (you ruled out feces).
• Root zone contamination from deck runoff.

Action Plan

1. Block dog access permanently.
2. Test soil for salts/chemicals (Extension lab).
3. If contaminated: replace soil in planters and repot palms.
4. If not: verify care history—palm fertilizer 3×/year? Copper spray quarterly? Freeze protection?

Fertilizer Note

Don't just add soil on top. Must replace root zone. Large palms = big job. Pro may be needed.
