Maybe the combination of the METAL trellis and the heat is frying them,and i don't think the fishing line is helping either.

I think if i were you i'd go buy a spool of that green tying stuff at the garden center or walmart.I'd also get rid of the metal trellis,and use wood,bamboo etc.JMO

As for the soil,did you look at the roots b4 you transplanted it??? Were they all curled around in a circle.If so,you should have loosened them,and added some new soil to the new hole.I always use Miracle grow potting soil when transplanting things.

Do you have a picture???

Something to try when you have compacted soil -- which it sounds like you have and I think this is causing the problems -- you can take a screwdriver or other pointed instrument and push it into the soil all around the top of the container, naturally avoiding the stem areas. Then water well. Some say this will simply compact the soil more, but that hasn't been my experience. I don't think untwisting the vines would do what you're describing.

Thank you Kathi and posiegirl.

It never even OCCURRED to me that the metal trellis would fry my poor plant. And the fishing line even - oy! I feel like a brute.

I'll do as you suggest, Kathi, though I've been looking everywhere for a pretty, curvy 6' trellis and this metal one is the only one i've seen. Any suggested sources for a pretty 6' non-metal trellis? Would plastic also get too hot?

posiegirl, I'm afraid more water isn't what it needs - the soil is pretty moist already. do you have any suggestions for how to amend the soil without causing further harm to my poor benighted MG?

I don't think it's the trellis either. These are from a couple of years ago when I had them on a wire trellis. This was just the beginning of the blooming period.

wow, those are beautiful! That's what I'm aiming for. Mine don't have those luscious heart-shaped leaves, though -my leaves are smaller and 3-lobed.

I'll try to take & post a close-up photo of the dying vine tips to aid in diagnosis.

If you were trying to "comb" out a relatively fully grown morning glory vine there is a big possibility that you broke some of the vines in the process. I'm surprised Home Depot sells morning glories in 5 gallon containers. You might have been better off to leave the bamboo trellis and train the new growth onto the new trellis. Morning glories are almost impossible to kill and can tolerate the harshest of soils and they're excellent climbers. If you like morning glories next year buy seeds and start them. Once they get going you'll never have to buy seeds again. I still buy the Heavenly Blue seeds every year to make sure I have enough blue ones. The pink and purple ones seem to become dominant.

Those are beautiful MGs. I think you're right about having broken some of the vines. I also think it was rootbound so, despite all the warnings, I did move it into a slightly bigger pot this evening, just before dark, and then gave it a good soaking. We'll see if that either finishes it off or gives it a second lease on life.
