What size is the pot? I don't grow in containers, but those who do might want that information.

The pot is not that large, about 16 in. in diameter or about 7 1/2 gallons of soil. To the side or front of the Dr. slightly, there is also a heuchera that's returned nicely, although it seemed to never leave with bigger leaves, and a smaller tiarella cordifolia that's also up and coming. Attached is a photo. The damage seems to have gotten worse today. My baby is hurt'n it seems, but I don't think it's dying. You'll see in the photos a small white caladium bud to the bottom right. That's where I squeezed it in. On the old wood are some buds you may or may not see - no activity thus far. Things seem crowded but I was told the Dr. does actually well in pots, and given the results last year, that seems to be the case. I wish I had photos of it last year though. Right now, I'm awaiting an order of moopoo tea bags. I had great results with it last year. Perhaps this may help. I just can't believe it's dying. I just think it's hurt from the disturbance and needs time, but I'm just not sure either.

Oh... I should add that the 2nd photo is a pic of where the new growth came in and is now dying off. It started at the crown or the base of that old stem and now has just completely flopped. Like I said it looks worse today.

Cut the stem back and hope for the best. I find when growing clems in containers that adding other plants does crowd them a bit. Even clematis vines that don't produce huge top growth develop large root systems and they do resent any disturbance. If I was going to add any other plants, it would be some sort of very shallow rooted groundcover. Nothing larger like the heuchs or caladium tuber. And nothing that needs to be dug up and removed. You want to avoid any root disturbance.

Is it planted deep enough?

Many thanks. And, yes I agree. Looking at the heuch has me wondering about space limitation and I'm definitely lamenting the caladium as an addition. The Dr. was planted so that the crown was at least 2 - 3 inches below the soil line for winter protection. I just can't get over the fact that the new growth that peaked its head from that crown just flopped so quickly and I have no idea why the other buds on the old wood have failed to respond to the warmer weather. I just can't give up hope, even if it looks bad. I've had good results from moo poo or alfalfa tea bags when dealing with roses on their last leg. Perhaps it'll help heal the damage I may have caused. But if by the end of June there's no significant change, I'm afraid that may be it. Given that it is in a container and the fact that we had a harsh winter in DC, I'm wondering if the below freezing temps may have weakened it. If this doesn't work out and I'm really hoping it does, I refuse to give up on the Dr. b/c it's just such a beautiful clem and will plant another one in a container all on its own. Perhaps I'll do that next to this one just to offset what I've lost.
