1. Stem Cuttings
Materials:
- Sharp, sterile pruning shears
- Rooting hormone (optional)
- Potting mix
- Small pots
Steps:
1. Select healthy, non-flowering stems that are 4-6 inches long.
2. Make a clean cut below a leaf node.
3. Remove the bottom leaves, leaving 2-3 pairs of leaves at the top.
4. Dip the cut end into rooting hormone (if desired).
5. Plant the cutting in a small pot filled with well-draining potting mix.
6. Water the cutting and place it in a warm, humid environment.
7. Keep the soil moist and provide indirect sunlight.
8. Roots should develop within 4-6 weeks.
2. Air Layering
Materials:
- Sharp knife
- Rooting hormone
- Sphagnum moss
- Plastic wrap
- Wire or twine
Steps:
1. Choose a healthy branch and make a shallow cut around the stem, about 1-2 inches long.
2. Apply rooting hormone to the cut.
3. Surround the cut with a ball of sphagnum moss and wrap it securely with plastic wrap.
4. Secure the plastic wrap with wire or twine.
5. Keep the moss moist and protect it from direct sunlight.
6. Roots should develop within 6-8 weeks.
7. Once roots have formed, cut the branch below the root ball and plant it in a pot.
3. Seed Propagation
Materials:
- Fresh Osmanthus fragrans seeds
- Seed starting mix
- Seed trays or pots
Steps:
1. Soak the seeds in warm water for 24 hours.
2. Fill seed trays or pots with seed starting mix.
3. Sow the seeds on the surface of the mix and gently press them in.
4. Cover the seeds with a thin layer of sand or vermiculite.
5. Water the seeds and place them in a warm, dark location.
6. Keep the soil moist and provide bottom heat to accelerate germination.
7. Seedlings should emerge within 2-4 weeks.
4. Ground Layering
Materials:
- Healthy branch
- Shovel
- Soil
Steps:
1. Choose a low-growing branch and bend it down to the ground.
2. Dig a shallow trench and bury the branch, leaving the tip exposed.
3. Secure the branch in place with soil or rocks.
4. Keep the soil moist and provide indirect sunlight.
5. Roots should develop along the buried portion of the branch.
6. Once roots have formed, cut the branch from the parent plant and transplant it.
