How do you know if your sago palm is dead?

To determine if your sago palm is dead, check for signs like a completely brown and mushy trunk or fronds that have turned dry and brittle. Gently scratch the bark; if the tissue underneath is brown and dry, the plant is likely dead. Additionally, inspect the root system; if the roots are black and slimy, they may indicate rot. If you see no new growth after a season, it may be time to consider replacing the plant.
