Off to a bad start, apparently.
I noticed tiny spiderwebs in my new u.humboldtii pot today - all over the surface of the soil. Without a magnifying glass, I don't think I'd have been able to see them. I moved some parts of the plant to a completely new pot of sphagnum after submerging them in water for about 30 minutes. With any luck they won't be bothered by being uprooted so soon.
