🌸 Dendrobium Mature Plant Care Guide

Mature Dendrobiums need slightly different care than young plants—especially for flowering.

---

☀️ Light

• Bright, indirect light is essential
• Can tolerate some early morning sunlight
• Insufficient light = no blooms

---

🌡️ Temperature

• Ideal: 18–30°C
• Slight temperature drop at night helps trigger flowering
• Avoid sudden cold drafts

---

💧 Watering

• Water when the medium is almost dry
• Mature plants prefer a wet–dry cycle
• Reduce watering during rest period (especially after flowering)

👉 Overwatering = root rot (very common issue)

---

💨 Humidity

• Ideal: 50–70% humidity
• In Kerala climate, usually sufficient
• Increase airflow to prevent fungal issues

---

🌱 Potting Medium

• Use well-draining mix:
  • Bark chips
  • Charcoal
  • Coco husk
• Repot only when medium breaks down or roots outgrow pot

---

🌿 Fertilizing

• Use balanced orchid fertilizer (e.g., 20-20-20)
• Feed:
  • Once a week (weak dose) during active growth
  • Reduce feeding in dormant phase

---

🌸 Flowering Tips (Very Important)

• Mature canes (pseudobulbs) are key for blooms
• Do NOT cut old canes—they store nutrients
• Provide:
  • Bright light
  • Slightly cooler nights
  • Reduced watering before bloom season

---

✂️ Pruning

• Remove only:
  • Dead roots
  • Completely dried canes
• Healthy old canes can rebloom

---

⚠️ Common Problems

• No flowers → Not enough light
• Wrinkled canes → Underwatering
• Yellow leaves → Overwatering or root damage
• Black spots → Fungal infection (improve airflow)

🌼 Pro Tip for Alans Garden

In Kerala’s humid climate:

• Focus more on air circulation than humidity
• Mounting Dendrobiums on wood/logs works very well for mature plants
