FlytrapCare Carnivorous Plant Forums

I have an indoor bog garden. It's a plastic window box, about 24" by 10". My plans for it are sarracenias, if I can keep them happy, and definitely some VFTs. Maybe some sundews. The substrate is LFSM with a decent bit of orchid bark and perlite mixed into the lower areas. It needs a mulch, though, it's drying out a bit thanks to indoor humidity lack.
Pine needles are the best mulch for bog gardens, right?
Can I use green pine needles, or do they have to be pre-dried? I don't need an entire bale of them, so I figure the best route to take is just to gather a gallon bag or two and rinse 'em real well to remove any potential nutrients and/or bugs.
