canna seed germinating
I have started germinating several canna seeds.I'm new at this. Nicked seed, soaked, placed them in styrofoam cups with holes in bottom and filled cup with good potting soil. (not seed starting medium.) Placed saran wrap with rubber bands on tops of cups. Placed cups in greenhouse in sun where it is very warm as our temps have been extremely hot. Some (not very many) have sprouted. The ones that haven't sprouted, i loosened soil to expose the seed and it had what looked like little bluish-gray speckels on them Could this be some sort of mold? Maybe got too hot in greenhouse.I then moved them outside in semi-shade. What's up with my method and is there anything I can do to save any of these seeds?
