Short answer
Parlor palms (Chamaedorea elegans) are highly sensitive to 'wet feet' due to their slow growth rate and relatively low water requirements. Root rot is most effectively treated by repotting the plant into a fresh, well-draining potting mix and trimming away any dark, mushy roots.
Root rot in a parlor palm typically manifests as fronds that become dull, yellow, or wilted despite the soil being damp to the touch. Because these palms prefer to dry out slightly between waterings, chronic overwatering quickly overwhelms their root system, making this a serious condition that requires immediate attention to save the plant.
Chamaedorea elegans requires soil that remains lightly moist but never saturated. If the pot lacks sufficient drainage holes or the soil is too dense, water accumulates around the roots, leading to oxygen deprivation and fungal decay.
Check: Gently lift the palm from its pot; healthy roots should be firm and light-colored, while rotted roots will appear dark, mushy, and may have a distinct unpleasant odor.
Fix: Repot the palm into a clean container with drainage holes using a fresh mix of peat-based potting soil amended with perlite or pumice to increase aeration.
Using decorative pots without drainage holes often causes water to pool at the bottom where the palm cannot access it. Even if the topsoil feels dry, the bottom of the root ball can remain waterlogged for weeks, encouraging pathogens.
Check: Check the bottom of the decorative planter for standing water; if water is present, the drainage is insufficient.
Fix: Use a nursery liner pot inside the decorative container and always empty the cachepot or saucer 30 minutes after watering.
Parlor palms grow slowly, especially in low light conditions, and require very little fertilizer. Excess salts from over-fertilizing can burn delicate root tips, weakening the plant and creating an entry point for root rot fungi.
Check: Inspect the surface of the soil for a white, crusty buildup of mineral salts or fertilizer residue.
Fix: Flush the soil with distilled or filtered water to leach out excess salts and discontinue fertilizing until the plant shows signs of active growth.
When to worry
If the base of the stems becomes soft or blackened, the decay has moved from the roots into the crown of the palm, which is often fatal.

Diagnose my Parlor PalmYes, trim away heavily damaged or yellowed fronds so the plant can divert its limited energy toward root recovery rather than trying to support dying foliage.
You can rinse the healthy root system with a diluted solution of one part 3% hydrogen peroxide to three parts water during repotting to help sanitize the roots and provide oxygen, but this will not fix the underlying overwatering issue.
While the fungi involved are typically present in most soil, root rot is generally a result of environmental conditions rather than an airborne contagion. Isolate the plant to ensure you don't accidentally overwater it while it recovers.
