Carnivorous Plants/Dormancy


Hello guys

Im from Puerto Rico and I got this sarracenia purpurea and darlingtonia "cobra plant" and they are growing very good so ....we are in december should I pit in my refrigerator to dormancy or what ?  Should I leave it in the pot ? And I got this other ginormous fly trap really big and still growing what should I do ?  It doesnt matters if they are growing to put them hobernate now ? This plants gets 16hours of light t5ho

Hi Gabriel,

What I would do with your plants right now is drop your photoperiod down to the equivalent of here on the mainland.  This site will be helpful:  It will be more effective if you do it somewhat gradually over the month until you get it to what you see on this page.  If it's possible to keep the plants cooler that will help.  Once you have the plants at that 9-10 hour day, it would be helpful if you put the flytrap and Darlingtonia in the refrigerator at night.  That would probably be enough, and it is similar enough to what would happen in nature.  The S. purpurea should be fine without doing that.  Clip off leaves that brown up, which should happen with the shorter days.

I don't have as much direct experience with inducing the dormancy period in the tropics, but we've talked to friends in Hawaii, and they say Sarracenia do fine since Hawaii does experience a change in daylight hours.  Venus flytraps slow down and die if they don't get a dormancy, and I don't know anyone there that has tried Darlingtonia.  They're hard enough to keep alive here.  Here's a resource that should be helpful.

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?
