Dragon Tree (Dracaena marginata) Yellow Spots: Not Spider Mites

Ruling Out Spider Mites

Since you've inspected with a magnifier and found no mites or webbing—and the nearby Majesty palm has them—your Dracaena's issue is likely root-related, not mites.

Probable Cause: Root Rot

Dracaena marginata is prone to sudden decline from root rot, often due to overwatering or poor drainage.

Diagnostic Questions

  • Which leaves are affected—all, lower, or upper?
  • How do you determine when to water? (Frequency? Method?)
  • When was it last repotted?
