Carnivorous Plants/Rainwater


Dear Jeff and Jacob,

 I have a cape sundew collection coming and I have collected rain water.
However, the rain water is yellow . Is this water safe to use and do you know why it's yellow?


There are many reasons why water is yellow, but without knowing anything about your environment and collection system, I can't speculate what is causing it.  It's best to be safe than sorry, so avoid using the water at this time.  Clean out the barrel or bucket.  Use a mild sanitizer and rinse thoroughly.  If you're collecting rainwater from your roof and gutters, you may need to use a different system of collection since the roof and gutters may be adding contaminants to your water.

Good growing!

  • Why is my sundew not producing dew?
  • Is now a good time to divide my Sarracenia?
  • Why are the traps turning black?
  • What's a good substitute for perlite?
  • Why didn't my seeds germinate?
  • How do you deal with pests?
  • Can you identify this carnivorous plant for me?
