It's still alive and has pushed these tiny leaves within the last 2-3 weeks.

This got a good spray of Bayer 3-in-1 after the photo was taken to take care of the mealybug(s). Last year the tiny leaves turned black pretty quickly due to fire (or some other) blight, so I'm taking care to keep leaves dry and spraying with copper sulfate occasionally. Other than the morning sun, bright shade, and careful watering, is there much else I can do to get this in a more energy-positive state? This had almost zero roots when collected, so I suppose it's fighting the chicken-and-egg problem of too few roots and too little leaf surface area to gain energy to produce more.
