This prevents the plastic pot from melting. Because I am a little paranoid about the effects of unknown variables, I always use dead grass from areas I know haven't been treated with pesticides or herbicides. I think it may be important to let the seeds sit on a moist soil surface for a week or two before they are fire treated. Germination should follow in a few weeks. Holding the flower petals with thumb just under the mature stamens I briskly rub or flick the anthers a dozen or more times.
