Sometimes they just do not germinate.. not because of you or handling but because of genetics. Not every seed is naturally going to germinate. Only the strongest seeds and the healthiest will germinate.I just had a Barney's farm red cherry berry that didn't germ. I bought 5 femmed, 1 my wife accidentally wiped behind the kitchen counter, another didn't germ. I will probably germ another one soon, but decided to go with another bean at the moment. Weird that the seed didn't pop, because the seed looked very healthy, and my techniques are solid.
