If anyone intends to store Mayan potato seed, you will need to store them in the fridge now as they are already starting to sprout.
I'm such a numpty - I forgot to do that and ate all mine! Totally delicious though. Oh well I'll buy some more this year and try and remember to save some..... :)
I've had no problems with my Mayan Twilight, very firm, no softening whatsoever and only stored at room temperature.
I did let the plant die off for some weeks before digging them up, maybe that's the answer or maybe it's Twighlight only and the others sprout quicker. I did notice Mayan Queen was a bit of a crazy. wild sprouter when it arrived in the spring.
