The Venus fly trap is one of only a very few plants that catches and eats insects. It does so by closing its two trap leaves around any insect which touches the three trip hairs inside the trap leaves. Venus fly trap seeds are usually harvested in May or June, so it's best to purchase seeds in June or July while they are still fresh. There is no need to stratify, or refrigerate Venus fly trap seeds prior to germinating.
Fill a growing tray with a 50/50 mix of sand and peat moss. Dampen the mix with distilled water from a spray bottle. Use only distilled water, never tap water, as the chemicals in tap water can be harmful to the seeds and plants.
Sprinkle the tiny Venus fly trap seeds evenly over the surface of the planting mix. Shred a small amount of peat moss between your fingers and dust the seeds lightly with the moss. Do not bury the seeds because they need light for germination.
Spray the Venus fly trap seeds gently with distilled water, keeping the soil damp but not soggy.
Place the growing tray inside a plastic bag that acts as a small greenhouse. Seal the bag or tuck the opening under the growing tray so the bag will hold in warmth and humidity.
Place the growing tray in a warm room with plenty of indirect light. Do not set the tray in direct sunlight or seeds may bake. Keep the tray consistently warm at 70 to 85 degrees F. Open the bag occasionally for air circulation, and to spray a light misting of distilled water.
Watch for seeds to sprout in 14 to 28 days. Some seeds may take longer. Remove the tray from the plastic bag as soon as seeds sprout, and place the tray in direct sunlight where it can be kept at 70 to 85 degrees F. Do not feed or fertilize your Venus fly trap plants.
Transplant your Venus fly traps into individual pots at six weeks. Pots should be filled with a 50/50 mix of sand and peat moss. Keep the soil damp, but never soggy, by spraying with distilled water only. Keep the plants in a sunny window.
