An unexpected visitor reminded me yesterday that my house is not childproof! An odontoglossum was knocked from the shelf to the floor, cracking its pot when it fell. I figured since the plant had already been disturbed, I might as well switch out the potting mix. Unfortunately, being in the middle of an ice storm, the power went out and my poor plant had to lie naked and exposed on the counter all night. Hopefully my mix of bark, sphagnum and the dregs of a big box mix (mostly perlite and tiny chunks of bark) will suffice, though even the experts occasionally kill an orchid when they repot.
