The Q&A Archives: Palm plants

Question: I have some Palm plants which are presently about two feet tall. They are situated where they can get sunlight and I water them about once a week.
The leaves are starting to turn yellow. What so I need to do to bring them back to life?

Answer: Palms may or may not retain their old leaves, so what you've observed may be normal for the plant. The fans can be cut off if they're unattractive to you. It's not unusual for palms to have just one row of leaves at the top of the trunk. 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 the sprinklers are giving them. Periodic deep soakings will also leach salts away from the roots. You may want to inspect the leaves at the top of the palm to inspect the leaves; you may find 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 palm, 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. Your palm may not start growing again until next spring, but if you feed it, and water it regularly, it should perform well.
