Dendrobium 'Pravit' (Likely Praneet) Black Spots: Rest Period and Fungus

Name Clarification

No registered 'Pravit'. Likely Dendrobium 'Praneet' (common label error).

Core Issue: Missing Rest Period

Dendrobiums need a dry winter rest after blooming. Continuous watering/feeding forces weak, spotted growth and root rot (drooping old canes). Black spots = fungal infection from overwatering.

Recovery Plan

  1. Repot in fresh bark (small clay pot).
  2. Remove all mushy roots.
  3. Withhold water—only morning misting—for rest period.
  4. Treat black spots: Copper fungicide spray or remove affected growth.
  5. Stake securely (rhizome clips/bamboo).
  6. Resume heavy water/feed only when new growth emerges on its own.
  7. Warm grower: Keep >60°F.

Flowering

Proper rest triggers bloom. Patience—may take a cycle.
