Strelitzia Nicolai - Seeds and Germination

Strelitzia Nicolai seeds have a hard skin. 
That's the reason why the seeds take so long to absorb the water needed by the embryo.

Previous treatments:
 To soften this cover soak the seeds for two days at room temperature.
After that, warm some water to about 50 ° C and immerse the seeds into it for half an hour.

The ideal substrate is a mixture of sand and black  peat in equal parts. 
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.

The seeds may take a month or a month and a half to germinate under perfect conditions.
But this time could be over than a year if the environment is not suitable.
For all that time we have to keep constant moisture and temperature.
In order to improve germination, the temperature should be around 25ºC.
