Sprinkle evenly on a pot of soil. Use a soil mix of 50% peat moss and 50% perlite. Make sure the soil is completely moist. Use a 4-inch pot if you are sowing a small pinch of these seeds. Sprinkle your seeds evenly over the soil and very gently tap them down. It's a lot easier to sow your seeds in one pot and separate them later after they germinate.
Fungal and mold spores grow in damp conditions, the very conditions necessary to germinate your seeds. To prevent mold and fungus, spray your seeds with Neem oil or a sulfur-based fungicide. Throughout the germination period, watch for mold and fungus and treat accordingly.
Keep your pot in standing water. Use a tray or a bowl to set your pot in, and fill it up with water. Keep the water line no more than halfway up the pot. Use low mineral water. Keep the temperature at 75° for optimal germination. (Unlike other US-native carnivorous plants, flytrap seeds do not require stratification.)
Your seeds will germinate within four to eight weeks, depending on temperature. Look for tiny versions of the adult plant. As soon as you see signs of germination, make sure your seedlings are getting lots of bright sunlight. Place your seedlings on a brightly lit windowsill or grow them under strong fluorescent lights.
