I'm setting up a planted terrarium for the first time. I'm using NeHerp's temperate substrate, and I chose to use Phyla nodiflora since this is native to the snake's habitat (Cali Red-Sided). I have two plants, which I placed in the terrarium on Wednesday. I know that I can expect some minor die back as the plants acclimate to the terrarium, however as I've never done this before, I was hoping for some advice.

Here's how things currently look:



So, you can see that the rear plant has a couple bright green shoots, with a few that aren't looking so hot. The front plant looks more like the "bad" parts of the other plant, tho there's some bright green in there. Should I be trimming away those drier bits so the plant can better establish itself? Or should I give it time to come around on its own?
