Looks like it got dried out at some point. Would be a lot easier to manage planted in the ground - except for the rampant growth these tend to produce once established.

You can only hope that's the case. They are horribly invasive garden thugs.

If the plant had lots of roots showing when removed from the original pot, and the whole mass was plunked into a larger container of soil of somewhat different composition and density, any applied water may be coursing through the new soil and going down the sides of the pot. Try to poke around and see if the root area is getting damp.

And have a few weeks' more patience, such a large transplant is bound to complain for a while.

Was the plant growing inside when you purchased it? It looks as if it might be adjusting to outside sun and previous lack of water.
In any case, I doubt you will kill it. It will recover, and if in the ground, ....with a vengeance.

They are horribly invasive garden thugs.

They may be in Mississippi but not here......rampant growth, yes, but that's to be expected from a large vine. They do produce some root shoots when well established and happy but nothing like another vine or two I could name :-))

Not really a great choice of vine for growing in a container or at least for long term container growth. As mentioned, would be much happier in the ground. Just provide a very sturdy support system.

When I bought the plant it was outside in the nursery.

When I repotted, I didn't cover the holes in the pot and had no tray so I remember hearing the water drip down the deck. Maybe that's why it dried up.

I am going to give it a little more time as Larry suggested and if it doesn't improve, I'll put it in the ground. I was originally concerned about it getting out of control (even if in Seattle, didn't want to risk it) but sounds like a non-issue.

Thanks everyone!
