I always gey my seeds to germ within 48 hrs. Shallow dish with some water in it. Seed wrapped in paper towel. Put in a dark warm place. I always put mine on the top shelf of a cabinet in the kitchen. Keep paper towel moist at all times. Never fails.
Put your baby seedling about a quarter of an inch into the soil and cover it back up. Water slightly, and you're good to go.. just like any other plant.
It's a weed. It can handle some dirt. Even special plants and flowers handle dirt from day 1 just fine.
That's just my thoughts though, but I am sure there are some professional growers that may have different suggestions like drop it in a cup till it sinks, stick it in a pot with 100% humidity, blah blah blah...
Regardless, I'm sure you'll get something to pop no matter what method you to decide to go with.. within reason of course.
