Between the ends placed on the ground, the potatoes put in a glass of water in January and then in hot February, there was no germination or they hardly really started at the end of February with better success in water.
I'm even beginning to doubt that water is necessary, like a potato they must sprout spontaneously. Or can it be placed on warm moist earth?
I bought the tubers in a supermarket that wasn't even organic.
I would be tempted to say:
a) there is enough water in the potato to feed the germs ...
b) the potato is dormant; that seems to me the first factor - being tropical, the cold should not play (or little)
c) the potato is very sensitive to temperature: I think that + 25 ° C optimizes germination
d) no doubt that a little humidity in the environment is another signal that the potato could perceive - I think a very slightly damp soil pot is the easiest way; it is a natural "buffer" ...
I opted for a jar with water placed on the radiator cover it's hotter than last year
