Likely causes
Overwatering
Most likelyHow to tell: The base of the plant feels soft or mushy, and the soil smells sour or swampy. The fronds may droop or turn yellow quickly.
What to do: Remove the plant from its pot and trim away any mushy, black, or slimy roots. Repot into fresh, well draining soil and wait a week before watering again.
Poor Drainage
PossibleHow to tell: Water sits on top of the soil for a long time after watering. The pot may lack drainage holes or the soil may be too dense.
What to do: Ensure your pot has large drainage holes at the bottom. Use a cactus or palm potting mix that includes perlite to improve drainage.

When to worry
Root rot is a life threatening condition for a Sago Palm. If the base of the trunk is soft, the plant may be too far gone to save.
Stopping it coming back
Always allow the top half of the soil to dry out completely before watering. Never let the pot sit in a saucer of water.
