Nematodes in Houseplants: Rare & Difficult to Treat

Suspected Nematodes? Probably Not.

Root-knot nematodes are uncommon in indoor potted plants and require lab diagnosis. Symptoms mimic other issues (overwatering, root rot).

If Confirmed

• Nematicides are costly, toxic, and only temporarily effective.
• Best option: discard plant and soil; sterilize pot.
• Start fresh with sterile mix.

More Likely Culprits

Fungus gnat larvae, root rot, or fertilizer burn cause similar root symptoms. Address watering and drainage first.
