richness for lemon balm

Not that the plant needs it (I don't think it's a heavy feeder), but I'm short on potting soil so I mixed some old tired soil from an empty planter with fresh, heavy vermicompost from the bin (worms are still migrating, but few enough in there now that I can start sifting them out). Rubbed between my palms until the moist clumps of compost worked into the dry, finer old soil becoming a nice-feeling crumbly mix.

I only found two worms in the compost when I first lifted handfuls from the old bin, and one more when I was mixing the soil. Used it for this bit of lemon balm that's been growing in the nearly-empty oregano planter (I'm not sure how the lemon balm got in there) and looking surprisingly healthy. I levered it out with an old butter knife that is one of my gardening tools, and put it into a pot with the new-mixed bit of soil and compost.
