Question
Hi Sarracenia,
    I have had your "Tropical mix" for about 2 months now, and all the sundews are doing great.  But how often should I change/clean the 2 inches of water I maintain them in?  Are these like aquariums for fish that need frequent water changes, or should I be leaving the whole situation alone and not disturb the plants too much?
    What is the date of your fall  open house this year. I'd love to come.
                         Thanks, Richard Westlund

Answer
Hi Richard,

There's no hard fast rule for this.  It's really more of an aesthetic thing than problem for the plant.  Algae just begins to build up in water trays over time and looks icky.  When you can't stand to look at it anymore give the trays a good rinse.

The next open house is September 13th and 14th.  Go to http://www.cobraplant.com/openhouse to register.

Good Growing!
