Hello,
My S.Judith Hindle and Psittacina have shown some signs of dormancy. Since this is my first time to grow Sarracenia, I am not sure how to help them enter dormancy.
Here the climate is mediterranean-like. In winter, the night-time temp is above 45F, and daytime temp is around 65F. Humidity is from 50%(noon) to 80%(night).
Now I only keep the soil moist, and stop keeping them stay in water. They receive about 2 hours direct sunlight at afternoon. Is it correct and enough for them to enter dormancy? Shall I put them in a shade place?
Thank you.
Zhilin

I don't think this will be necessary. just leave it where it is and keep only damp. Sarracenia will enter dormancy in response to shortened Photo period and lower temps. you don't really need to Do anything. just cut off old pitchers.

Sarracenia will enter dormancy in response to shortened Photo period and lower temps. Has anyone observed if photoperiod or decreased temps has a greater effect over Sarracenia dormancy? Reason I ask is, my University has a little bog garden up in one of the greenhouses, and after talking to the head of the Plant Sciences department, he has sorta given me charge over the thing. Since its in a greenhouse, it wont be getting a drop in temperature, but they will be getting a decreased photoperiod. Is this enough to supply them with a dormancy? After inspecting the crowns, they all appear dormant, and even the venus flytraps are sending out dormancy growth, but is this "dormancy" deep enough? |

You should grow tropicals if the temp dosen't go down.

as far as i am aware, reduced photo period is the main factor influencing Sarracenia Dormancy. this should be adequate dormancy for them in the greenhouse.
This is my opinion.

SHould be ok, but make sure they're not near any walls which will radiate heat outwards at night.

I had this same question a few weeks ago, so I decided to meet up with Tom Dougherty of the SDCPS. As it turns out, winters in San Diego are cold and dark enough to give cp's a dormancy. Oddly enough, he said he's never had any problem with fungus during dormancy.
