Sarracenia winter conditions


Recommended Posts

Hi!

I`m Nepenthes and Sarraenia grover and i live in Finland and my problem is what i do to my sarras when winter comes? Does sarras need little colder on winter, or can i putt more light? All my plants is indoor and this is tricky problem. I have putt some extra light to my cacti and they seems to like it. Can i do same to sarras? Many has said, that they have to keep on basement little colder, butt i have no basement. Any ideas?

Yes, sarracenia need a dormancy period over winter. Over the last few winters here in the UK we've had temperatures down to -10C or -15C and most plants have survived outside in a greenhouse. I'm not sure of the maximum winter temperature they can tolerate but would guess about 5 to 10C would be the highest. If you don't give them dormancy they will get weaker and weaker and may eventually die. I imagine your temperatures are too low for them to survive outside so you'll have to come up with another solution. Maybe a room you don't heat or a garage? Another alternative would be to keep them in a fridge for a few months.

Ok, thanks! This helped me a lot! I have to think that fridge system. My collection is little and they dont need much space, so that fridge would be good for a while... My greenhouse is too cold, even i have heater there. I have to think!

Sarracenia purpurea ssp. purpurea can probably be left outdoors in the Finnish winter. Mine has survived outdoors here during the past two winters in a pot, protected only by a layer of snow.

I think it might be worth trying to put at least one of your Sarracenia on a cool, north-facing windowsill through the winter. Natural Sarracenia habitats can be surprisingly warm in winter, so the reduced photo period may be enough to make them go dormant.

For example, look at the winter temperatures in Wilmington, North Carolina. In November the average high is 21 degrees Celsius, average low 7 degrees, with a mean temperature of 14 degrees. Yet, presumably the native Venus flytraps and pitcher plants are going dormant by then.

It's possible to program some electric heaters to maintain a lower temperature during night, e.g. 8 degrees. I guess you can probably also get a similar effect by programming a timer so that the heater is on maybe half the time during the night. Doing that would make the room temperature a little more like that of North Carolina, and you'd save electricity.

I keep my Venus flytrap and Sarracenia outdoors as long as I can in autumn, putting them indoors in case of heavy night frosts so that they will go dormant naturally before I put them on the (4-10 degrees Celsius) windowsill for the winter.
