Seed • Air Layering • Grafting
Longan trees can be propagated in several ways, each with its own advantages and challenges. Choosing the right method depends on whether your goal is home growing, true-to-type fruit, or commercial production.

1. Propagation by Seed
Overview
Growing longan from seed is the most natural and beginner-friendly method, but it comes with uncertainty. Seed-grown trees do not always produce fruit identical to the parent tree.

How It Works
Seeds are extracted from fresh longan fruit and planted while still fresh, as viability drops quickly after drying.

Basic Steps
Remove seed from fresh fruit and rinse clean
Allow seed to dry for 24 hours (not longer)
Plant 1–2 inches deep in well-draining soil
Keep soil warm and consistently moist
Germination usually occurs in 10–21 days

Pros
Easy and inexpensive
Great for learning and experimentation
Produces strong root systems

Cons
Long juvenile period (6–10 years to fruit)
Fruit quality is unpredictable
Not ideal for commercial production
Best For
Hobby growers
Rootstock production

2. Propagation by Air Layering (Marcottage)
Overview
Air layering is one of the most popular methods for longan because it produces a clone of the parent tree and fruits much faster than seed-grown trees.

How It Works
Roots are induced on a branch while it’s still attached to the parent tree, then the branch is cut and planted.

Basic Steps
Select a healthy branch ½–1 inch thick
Remove a 1-inch ring of bark
Apply rooting hormone (optional but helpful)
Wrap moist sphagnum moss around the wound
Cover with plastic and secure tightly
Roots form in 6–10 weeks
Cut below roots and plant immediately

Pros
Produces true-to-type fruit
Fruits in 2–4 years
High success rate

Cons
Weaker root system than seed-grown trees
Requires an existing mature tree
Slightly labor-intensive

Best For
Home gardeners
Small-scale growers

3. Propagation by Grafting
Overview
Grafting is the preferred method for commercial longan production. It combines a high-quality fruiting variety (scion) with a strong seed-grown rootstock.

How It Works
A cutting from a desired variety is attached to a compatible rootstock so they grow as one plant.

Common Grafting Types
Veneer graft
Cleft graft
Whip-and-tongue graft

Basic Steps
Grow seedling rootstock until pencil-thick
Select healthy scion wood from mature tree
Make clean matching cuts
Secure tightly with grafting tape
Keep shaded and humid until union forms

Pros
True-to-type fruit
Strong root system
Earlier fruiting (3–5 years)
Best for orchards

Cons
Requires skill and precision
Lower success rate for beginners
Needs proper timing and care

Best For
Commercial growers
Advanced gardeners
