Carpinus Betulus - Seeds and Germination
Carpinus Betulus seeds can be sown without any previous treatment only when they have just been collected. But if you have to storage them, like us, you will have to treat them.
We have to put the seeds in a pot with sand. We have to put the pot under 15ºC for 1-2 month and 4ºC for 4-6 month after that.
We have to be aware of them along that time, because the seeds can sprout at any time. If one of them sprout we can sow the rest of them.
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 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 around 16-20ºC.
