Stevia seeds are so tiny, you have to be extra careful when handling them.
Paper towel method:
Place seeds you want to germinate in to a moist paper towel. You must to keep them in a warm place. Start indoors 8-10 weeks before last anticipated frost. Lightly cover and keep moist.
To retain moisture, simply put your wet paper towel within a ziploc plastic bag at germination, the outside shell of the seed splits and a tiny, white sprout called taproot pops out. When you see those little taproots coming out of the seeds, gently place them(root down) in to the soil Place in a south facing window or under grow lights until seedlings emerge. Seedlings emerge in 7-14 days.
Keep your soil equally moist for the next few weeks. Don't drown them! Over watering presents a big problem Transplant to individual containers when seedlings have at least two pairs of leaves. Be careful not to overwater your stevia. Only give them a drink when you need to prevent wilting. Before transplanting into the garden, but after the last frost, "harden off" plants by setting in a shady location outdoors for one week. After last frost, set plants out in the garden, spacing 18" apart.
