Hello Brian!
One of the resons why people fail with venus flytraps is because they use tap water. DO NOT use tap water, it kills the venus flytraps. Use either rain water or disstilled water. These plants are fond of sun, east facing windowsills are the best. If you do not have a east facing windowsill, try a south facing or west facing windowsill. DO NOT put them on north facing windowsills.
These plants like to be on a tray watering system, put them in a tray of rain or disstilled water only. DO NOT use tap water!! Wait untill the water in the tray evaporates completely, then wait about 1 day before adding more. They do not appreciate being constantley waterlogged.
Dormacy:
This is why most people fail with venus flytraps.
A dormacy lasts for about 3 months, and the plants have to be kept colder and slightly drier(DO NOT let them dry out, just reduce watering)
Less sun is also good when in dormacy. DO NOT let the plants freeze.
A good place for a dormacy is an UN-HEATED garage. The plants may die down to their roots(their will be no foliage) If this happens, UNDER NO CIRCUMSTANCES thorow it away. Some leaves will turn black. As soon as they do this, imediatley cut them off. This will reduce the risk of botris. And believe me, you do not want to get botris(the fluffy grey mould, it can kill plants) Oh yeah, NO DORMACY MEANS DEATH.
Cutting off dead leaves applies all year round.
Hope this helps,
Dino
