I was the lucky recipient of a Venus Fly Trap and Sarracenia for my birthday last October. My VFT is thriving and getting on perfectly well but my Sarracenia doesn't look happy and nothing I've tried seems to reverse the decline (see pic). I've zero experience with these plant so I'm hoping some knowledgeable folk on here maybe able to help.
The information I've read seems to suggest that the problem may be a lack of water or humidity which I don't think it could be either. I've always kept it wet (but not too wet) and there is plenty of moisture in the air at this time of year. It's on my north facing kitchen window sill and that room is not heated so I don't think it can be too warm or getting too much sun either.
I've always used rain water except once when I had run out and it hadn't rained for ages. I used boiled water from the kettle as I was told this would be ok but I don't think it liked it at all so I got rid of it and fortunately it rained a few days later. Could it be that?
Or, is this just natural winter die back and it will spring back in the spring?
Any advice would be greatly appreciated, thank you.
