Grafting of Cinnamomum verum

Grafting is the preferred propagation method for producing uniform, high-quality cinnamon trees—especially for commercial plantations and agroforestry systems.

Why Use Grafting?

  • Ensures true-to-type (consistent flavor & oil quality)
  • Earlier maturity (1–2 years faster than seed-grown)
  • Better bark yield and uniformity
  • Allows selection of elite mother trees

Types of Grafting Used

  1. Cleft Grafting (most common)
  2. Side Veneer Grafting
  3. Approach Grafting (less common, more labor-intensive)

Cleft grafting is the most practical for field nurseries.

Step-by-Step: Cleft Grafting

1. Rootstock Preparation

  • Use 6–12 month-old seedlings
  • Stem diameter: 0.5–1.0 cm
  • Healthy, disease-free, actively growing

2. Scion Selection

  • From elite mother tree
  • Semi-hardwood (not too young or too woody)
  • 8–12 cm length with 2–3 buds
  • Leaves trimmed (reduce transpiration)

3. Making the Graft

  • Cut the rootstock vertically (2–3 cm split)
  • Shape the scion into a wedge
  • Insert scion firmly into the split

4. Securing the Union

  • Wrap tightly using:
    • Grafting tape / polyethylene strip
  • Cover with plastic bag to maintain humidity

5. Aftercare

  • Place under partial shade (50–70%)
  • Maintain high humidity
  • Avoid waterlogging

Healing Timeline

  • 2–3 weeks: Callus formation
  • 3–5 weeks: Bud break (successful graft)
  • 6–8 weeks: Remove wrapping gradually

Success Factors

  • 🌡️ Temperature: 25–30°C
  • 💧 High humidity (critical)
  • ✂️ Clean, sharp tools (avoid infection)
  • ⏰ Perform during active growth season (rainy months in PH)

Common Mistakes to Avoid

  • ❌ Using immature or overly woody scions
  • ❌ Poor cambium alignment
  • ❌ Loose wrapping → air gaps
  • ❌ Direct sunlight exposure after grafting

Nursery Setup Recommendation

For your agroforestry ventures:

  • Mist chamber or simple humidity tent
  • Shaded propagation area (net house)
  • Labeling system for mother tree tracking

Integration Insight (For Your Projects)

You can establish a clonal cinnamon block alongside:

  • Aquilaria malaccensis
  • Other perfumery crops under your COPI / CAPI programs

This ensures:

  • Standardized raw material for essential oil extraction (CESI)
  • Premium-grade bark for export markets
