Sometimes I'll have a plant that for whatever reason hasn't developed enough roots and the media looks compacted or heavy. What I'll do is take something - a BBQ shish kabob stick works great, but I've used a sharpened pencil before too - and push it straight down into the soil throughout the pot to create "tunnels" from top to bottom where the o2 can get in and moisture can escape. If the roots are getting saturated and starting to rot, this can help. I figure it also helps create loose areas in the soil so the roots can expand more easily. I suppose it's a bit like aerating a lawn.

The point is that with a sharpened tool like those the roots aren't damaged and the soil isn't just jammed down, but they're carefully moved out of the way. Once the object is all the way down in the soil, I'll gently wiggle/rotate it some to create a slightly larger hole, but only a little; not so much as to damage anything.Â

I actually did this a couple weeks ago with my "standard" flexuosum, which had experienced one too many rain events immediately after being potted up, and it's happy and blooming again. If the soil's draining well I don't think this treatment's needed, but if it's not and the roots are getting unhappy it's another tool in the bag of tricks.
