If there are any jagged edges on the base of the leaves that you removed, cut them off with a razor blade or a pair of sharp scissors that can make a straight clean cut. Then cleanly cut off the trap and discard it. Insert the base of the leaf into a pot of live sphagnum moss and flatten it down so it is lying face up. One leaf will usually produce one to several plantlets. Young Venus Flytrap seedling.
Seed is best sown in the spring.
Sow them on standard Venus Fly Trap soil that has been flattened down. Place the pot in a sunny position or under artificial lights for around 16 hours a day. Water the seeds with the tray system. Seed is not the best method for this species because the seedlings will usually take around 4 or 5 years to reach maturity. Take a plastic seed tray or box and fill it with the same type of soil that the adult plant is grown in.
