If your CP's are not doing well, despite following all the expert's care directions, try live moss as a last ditch effort.
I was growing VFT (typical), sarracenia, and Austrailian drosera since last Spring. *They were doing well in the summer but, through only a few days of neglect during a hot summer, they weakened and started to die (sarracenia got burned in the sun, VFT's became overfed with garden insects outdoors and weakened, mold, etc.).
They have had a rough Autumn. *I tried doing everything recommended by the experts. *The only thing that has brought them back from the brink of death is live moss.
I don't even use moss native to the plant; although that would be ideal. *I live in the Pacific Northwest (not the most ideal conditions for CP) and just used moss growing in a shaded area on my lawn. * As scandalous as that may seem to experienced CP growers, it has worked and worked very well. *In fact, I'll go as far as to say that is the only thing that has worked to strengthen the plant. *The sundews are growing offshoots like weeds, and I just noticed a teeny new stalk starting to grow from the lone surviving VFT bulb that I wrote off for dead. *Not bad for winter time when they are supposed to be in dormancy!
I'm still uncertain about my sarracenia which started to wilt and molt when I tried to induce dormancy by storing it in a ziploc bag in the fridge as recommended by one CP site. *What a crock! *It got moldy instead. *I sprinkled it with garden sulphur and replanted it in live moss (rather than dried spaghnum/perlite). *I also had to cut off all the leaves that were molding, or getting slimy. *Currently, they have stopped wilting. *The mold is gone, and it's maintaining a brick color; don't know whether that's good or bad. * Well, at least it's better than going black and wilting.
I believe live moss has properties that help the plant where dried moss cannot. * Dried moss/perlite is too inert of a growing medium in my opinion.
In addition, I believe the CP's gain valuable nutrients through the live moss which dried moss/perlite/sand is unable to provide. *Experts seem to suggest that the plant gets enough nutrients from photosynthesis, and bugs, and that the growing medium should stay nutrient poor for best growth. *However, I think this is a misconception.
I am even giving my plants straight tap water (gasp!) and they are still flourishing while they are in the live moss. *Perhaps, the live moss helps neutralize, or filter the harsh tap water? *I don't know.
Live moss is much better than dried and will do wonders for a weakened CP. *It even helps deter the growth of mold compared to dried moss/perlite. Give it a try. *
The only downside is that the moss will grow tall over time and you'll have to trim it.
