On top of the seed, lay down two more sheets of filter paper. Wet the sandwich of filter paper and seed with distilled water. Use just enough water to soak the paper but not enough to produce standing puddles. Place the petri dish in a well lit area but out of direct sunlight. Many seeds need light to germinate.
Room temperature is good for germination of most prairie seed.
Avoid hot spots such as radiators or heat ducts. Likewise, a cold drafty windowsill may be too cool to allow germination. Keep the filter paper well moistened. Initially it is a good idea to check the moisture level a couple times a day until you know how quickly it is drying out and needs watering. It is this event which defines germination.
