Calocedrus Decurrens - Seeds and Germination
Germination rathe of Libocedro seeds is usully between 20-80 %
These seeds are really sensitive to fungi.
This specie needs cold stratification. So we have to put the seeds in wet sand under low temperatures, 1.5-4.5ºC for 1-3 months.
The ideal substrate is sandy one. We have to add fungicide.
Mix and water it well. Drain the mixture, pressing to expel all the water.
The soil has to be wet but no waterlogged.
Fill with the soil the container chosen to sow the seeds.
Put the seeds on the substrate, leaving two cm between them.
Cover with a layer of soil equal to the thickness of the seed.
These seeds need deep pots.
The seeds may take two weeks to three months to germinate under perfect conditions.
For all that time we have to keep constant moisture and temperature.
In order to improve germination, the temperature should be over 15ºC
