Answer: If your palms are acting differently than they have in the past, they may need to be fed, or they may need a deeper soaking than they are getting. Periodic deep soakings will also leach salts away from the roots. You might also inspect your palms for spider mites (look for webbing between the leaf fans and the stem). An infestation of spider mites can turn leaves brown prematurely. To avoid the problem, hose the foliage down every few weeks to remove the dust and any spider mites that might have taken up residence. If you want to feed your palms, you can spread several inches of organic matter over the roots so the nutrients released as the organic matter decomposes will trickle down into the soil, or you can broadcast an 8-8-8 complete fertilizer over the root zone. Palms are sensitive to salts, so don't apply any more fertilizer than the label recommends or you'll burn the roots.
Best wishes with your palms!
