Venus fly traps must be watered ONLY with distilled (i.e., deionized)
water.  Do not use tapwater because the chlorine and fluorine will be
destructive.  From November through March reduce the amount of water... do
not let the plants or the medium dry out but do not allow it to get as wet
as the bog.  Also, keep the plants cool in winter.

In Spring, move the plants outdoors in full sun and make sure they have
LOTS of water... as in the bog.  Rainwater is best or you can supplement it
with rainwater you have collected or water from a dehumidifier or deionized
water from your lab or supermarket.

Janice Glime is correct in saying that the red color is produced when the
leaves are mature and in full sun.  There is also a genetic factor... some
leaves tend to be more red than others, even in the same conditions.

DO NOT FEED THE PLANTS GROUND BEEF!  This is too much protein for the plant
and the meat will rot followed by the leaves rotting.  The leaves will
capture enough insects to get the nitrogen they need... another reason for
moving them outdoors in the Spring.  Don't worry about nitrogen level in
winter... if you lower their metabolism as suggested above.

You can find lots of information about these plants (and vendors that sell
them!) on the WWW:

auch in Deutsch. There are more than 500 different species in the world
with various and very interesting catching methods.

        Steve has posted lots of interesting information with links to
other WWW pages.

 Carnivorous Plant Societies

society is the International Carnivorous Plant Society (ICPS). But there
are many others.

Good luck!
