Echinocactus Grusonii - Seeds and Germination
Echinocactus Grusonii Seeds
Echinocactus Grusonii seeds have a growth inhibitor which we have to remove before starting this cultivo.
We have to put the seeds in boiled water and let them get cold for 1-2 hours.
The ideal substrate is a mixture of sand and black peat in a 1/3.
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.
It's recommended to sterilize the soil, by using fungicide, boiling the soil or even using the microwave (you can put the soil into the microwave for half minute)
Put the seeds on the substrate, leaving two cm between them.
Cover with a layer of soil equal to the thickness of the seed.
Echinocactus Grusonii seeds need 1-10 weeks to sprout.
We have to keep the soil wet and the temperature around 20-30ºC for all that time.
