Congrats on your plant! Hopefully this one should last a bit longer, especially if you follow a few simple guidelines:
First and foremost: DON'T USE TAP WATER!!!!!! This is true of all carnivorous plants. I can't stress how deadly this stuff is to CPs. These plants have evolved to grow in nutrient poor soil (hence the bug catching) and the dissolved salts and minerals in tap water WILL kill them. Use ONLY distilled water or rainwater. Just buy a plastic tray, place the pot in it and maintain an inch of water in the tray (Make sure the bottom of the pot you use has holes in it). The sphagnum moss will absorb the water from teh tray and stay moist. Which bring us to point number two:
You should grow it in a 50/50 mix of Sphagnum moss and sand or perlite. It doesn't matter which. You must use Spagnum moss, though. And Don't use potting soil! AND NEVER FERTILIZE!!!!! EVER!!!!
Just place them outside in full sun for at least 8 hours (Depending on where you live, the sun could be more or less intense during the height of the afternoon). If you keep them outside they should be able to take care of their own food. Don't worry about it if it doesn't catch too many bugs, Venus Flytraps photosynthesize just like normal plants, the bugs are like a bit of a nutrient supplement.
Also, these plants will need to go dormant during the winter. Depending on where you live you could just leave it outside, or, if you live in an area with bitterly cold winters, try removing the plant from its pot (taking care not to disturb the roots) leaving some soil around the roots. Wrap the whole thing in some paper towels, and apply some fungicide to ward off mold. Place this in a plastic baggie and put it in teh refriderator from Thanksgiving until Valentine's Day. Keep it moist during this time, it can never be allowed to dry out. Also, Vfts (Venus Flytraps) actively resent having their roots disturbed during teh growing season, so take care not to disturb them during repotting.
Try not to trigger the leaves too often. We all know how cool it is to watch teh trap close right before your eyes, but the mechanism that controls it is only designed to do it about 3-4 times. After that the leaf wears out and is unable to catch food. Trigger all of the leaves enough and you could kill the plant. Tease with caution.
I hope all of this helps, and hopefully some of my esteemed colleagues can give you some more help. Have Fun!
