This little Oerstedella has been fighting a long, hard battle against scale. Eventually, I put this little plant in a ziplock bag, added some Bio Kill, and shook it around until the entire plant was wet with insecticide. This seems to be a pretty effective small-scale way of applying pesticides, and is particularly nice as you don't get any overspray - particularly handy for indoor growers with no garden (like us here at OOAB) to use for a quick spray. After that, I potted it up in some Hydroton (LECA). This seems to have finally knocked out the scale, and the plant has responded with some pretty little flowers.
I hope it will now decide to start thriving a little more now that its energy isn't continually sapped by vicious little bugs!
