I got a starter Passiflora manta about two weeks ago. It had two healthy leaves on it. It came in a two inch pot, so after I'd had it one week, I repotted it into a 4 inch pot with orchid mix (soil and bark, not just bark) and perlite. I kept it out of the sun for two weeks, then introduced afternoon, dappled sun, not direct sun. Well, one of the leaves started to yellow, and then fell off yesterday. So it's left with one leaf. Is it going to lose that leaf too, and die? I've done all I can--I kept the leaf positioned over a pebble tray for humidity, mist it daily, and I keep the soil evenly moist, but not wet. It's fast draining. Any suggestions? I've wanted a manta forever and I fear losing this cutie.
