Wipe your pruning shears with alcohol. Fresh pruning cuts are susceptible to fungi and other pathogens in the area or on the blades of the shears themselves.
Prune any dead, brown, dry palm leaves at their point of origin. Chamaedorea radicalis is susceptible to one or two diseases such as gliocladium stem blight, which may kill individual fronds. If fungicide or improved cultural conditions do not control the disease, prune only once an individual leaf is clearly brown and dead.
Remove any pruned palm fronds from the area. Discard or compost them.
