Did the sprout have any color to it when they first sprouted? I just checked mine and had some that could have had a sprout but I think it was just the hair on the tip ends of the nuts that had matted together from sitting in the damp peat moss. I will be surprised if any of mine sprout. I bought them on ebay and even though after asking the guy told me he had kept them in the fridge in damp peat moss, I sort of doubt it.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
