The Fern spores I planted last year have sprouted. Oddity is that I planted two pots, one container was kept outside. It was prepared about a month or more before second container, which is the pot that seems to be sprouting on hormones. Instructions called for using a sealed container like Tupperware to keep the humidity high. As far as I can remember, when the sprouts emerge, that's the time to begin a regiment of spritzing and watering. Good we're getting rain I can collect for watering purposes. I don't have to purify water.
