Okay. I'll use the long fibered sphagnum I have.
One reason I was concerned about water is that it hasn't been raining for sometimes 2 weeks at a time this summer. It's crazy.
I also thought I would put several drain holes about 3 inches below the plant's roots for those horrible downpours we've been getting -- You know the kind that fill a plastic wastebasket in 1/2 hour and leave the soil almost bone dry because it just rain right off and didn't soak in.
I don't want the plant to DROWN or to DRY out.
