Lack of sun or light from being in the shed for so long? Then you put it back in full sun, even though it was for only a half a day. Sounds stressed out to me. Sorry I can't offer any healing technique for it. I'm not familiar with that type of Thunbergia. My beautiful marigolds that I have in pots are stressed out from TS Debby dumping 15 inches of rain on us. I hope it regroups for you!

Are you sure the soil is moist? My potting mixture begins to dry out after the bag's been opened. As a consequence, I have to "work" the soil to get it to take the water. Else, water pours through the pot and yet it's still dry as a bone.

Stick your finger in the soil and make sure it's not powdery.

If it's dry, place your repotted plant in a larger container. Add water to that container and let the plant "soak" until the soil takes in the water.

have totally eradicated any blue sky vine in this garden. will take over a whole tree, whole house, whatever. had to use an ax to chop the massive roots out of two locations. never again.....incredible blooms!.....:)

Zackey you might be right hopefully it's just in
shock. Juneroses I did check will a moisture meter and
it seems to be rather moist, I did put a little bit of
water in it today, the last time I watered it was 3 days
ago. Hopefully it'll come back. Thanks for the advice,
I see how it goes the next week, I believe that they
grow real quick, so it shouldn't take long to see what
happens.

Thanks

Thanks for the advice. I've been keeping it somewhat moist, but not wet. This week new growth has began on it,
and it already grew a few inches this week. It should be
growing good soon on the trellis. I'm going to keep it
in a container and trim it back often. It would be great
to have a place in the ground where it could grow crazy
and grow up a house, garage or building, but there isn't that much room in the garden.

I planted one on a 20' long trellis a couple of years ago, with a number of other vines. It has taken over the whole trellis. I don't regret planting it, as it quickly provided privacy, but I do cut back tendrils weekly to keep it out of a neighboring tree it's determined to take over. Planting it in a pot is probably a good idea!

I planted mine in a pot. It grew roots through the bottom of the pot and proceeded on it's quest to swallow the house LOL!!
