Seed Pre-Treatment

Hot Water Treatment

Sowing

Seed Pre-Treatment: Nick seed coat. Hot water soak for 48 hrs
Cover seed to a depth one or two times the diameter of the seed.

Watering
 

Germination
 

Germination of pre-treated seed usually occurs within 2-52 weeks.
Germination without pre-treatment of seed may be erratic over 12-24 months. To enhance germination, the following methods have been suggested (combine for best results):
Smoke treatment, soaking in hot water for 24-48 hours, peeling the waxy coat off (first soak seed in cold water overnight, then place between paper towels for 2 days), nicking of seed coat.
Optimum germination temperature 18-22°C. Higher temperatures may inhibit germination.

Pests and Disease
 

Species susceptible to Cinnamon fungus (Phytophthora cinnamomi) dieback
