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.

Please, guys! I don't want to lose this plant. I'm afraid the remaining leaf will turn yellow and fall off, and I doubt a bare stem will survive, will it?

I can't really address growing this specific plant, but when repotting and changing the growing conditions (light, temperature, humidity and all that stuff) it's not uncommon for a plants' old growth leaves to yellow and fall off. A healthy stem with healthy roots is quite capable of generating new leaves and growth from the stem. So even if the remaining leaf does fall off, you shouldn't give up as long as the stem stays green and flexible.

Thank you! So far, the remaining leaf is not yellowing. Yes, it did have to go through a lot of changes in a short period of time. And even if I lose the leaf, I know to not give up as long as the stem still shows life. Thank you again!
