Not sure why the mineral content of tap water would kill them. Logically you would think it would just make them grow bigger and better. But apparently this is not so. Matter of fact, I have tried to grow venus fly trap and sundew seeds in regular soil, just for the heck of it, and have yet to have any seeds produce seedlings. None. So apparently they need the poor nutrient soil type too.

But yeah, I've heard of a lot of people killing off venus fly traps by using tap water on them. Seems like everything I have ever read about them expresses this warning, but I guess many people just don't believe it. Even had a local nursery around here who set up a little bog area with venus fly traps, sundews, and pitcher plants, but they put it on the regular watering system that went to the rest of their plants. I told them they needed to use distilled water or rain water, but the guy acted like he doubted such a thing. Well, within a year, they lost all those insectivorous plants.

So no, DON'T USE TAP WATER!
