Treating Mold and Yellowing on a Sago Palm

Yellow/brown lower fronds in spring are normal shedding. White mold on soil indicates overwatering. Remove moldy top soil, replace with fresh mix. Prune dead fronds. If trunks are mushy, remove them—they're rotted. Reduce watering; sago palms need little water.
