Dendrobium Burana Fancy Losing Leaves: Fungus or Overwatering?

Your blooming Dendrobium Burana Fancy (Chicago, 65–70°F, weekly water) gets small black spots on leaves, then yellow, then drop. Not sure if evergreen. Roots dense, no sour smell. You ask about misting, repotting in bloom.

Likely Evergreen Type—Leaf Loss Abnormal

Evergreen Dendrobiums shouldn't lose leaves now. Black spots could be fungus (sooty?) or overwatering.

Check for Fungus

• Black sooty at leaf base or crown?
• Misting at night promotes fungus—mist only mornings.

Overwatering Suspect

Dense roots + weekly water + no drying = root zone too wet. Let mix become barely moist between waterings, especially in winter.

Repotting in Bloom Is Okay

Dendrobiums like tight pots. Use slightly larger pot. Handle gently to avoid bloom damage.
