It’s eating all the leaves of my morning glory and I can’t stop it. I’ve soaked the whole plant in neem oil and it isn’t helping. Amy ideas on how to make it go away?
I cannot find that species on any of your native caterpillar charts or lists. I am not sure, exactly, which that is.
The absolute best way will be to use biological means. The bacteria Bacillus thuringiensis will make short work of the caterpillars. It is harmless to mammals.

You could try Diatomaceous Earth, as well. It is just crushed up fossilized aquatic plants. It works wonders to shred the bodies of caterpillars as they walk over your plants.

In the Toronto area in the last five years or so we have noticed a pronounced lack of Heavenly Blue morning glory seeds for sale. Is this the case in other North American areas? If so, why so?
Morning glory is one of those plants that people hate or love. Some consider it very invasive.
I did an internet search for Heavenly Blue and it was available from reputable, well known seed catalogs. We don't make product or vendor recommendations, but it is for sale online.
I am in Columbus Oh. Plant did quite well this summer. I didn't have a proper trellis. Do I need one in the spring?
If you would like them to trellis upwards, then it would be a good idea. Otherwise, they are highly invasive and will gladly trail along the ground, too!

The pot sits in back garden where it gets the afternoon sun only. Do I move it to side door where it will get morning sun only?
Since they are only open in the morning, the eastern exposure might be best.

I grew morning lory from seed in a seed tray and planted seedlings out in a pot. They have flourished - leaves scrambling all over trellis - but have not produced a single flower. I've grown them before in a pot though in a different garden but this is a new problem. It is a sunny garden especially in the morning, and sheltered, but this pot is against a north facing fence.
This sounds like an issue with soil that is too fertile. These plants become invasive in minimally disturbed areas, and poor soil. It may be that you will have to try again next season, or plant something that saps nitrogen fairly quickly. Mulch is another good way to leech nitrogen, as the mulch removes it as it breaks down.

I would like to dig up morning glories in my backyard and grow some them inside during the winter. Will they grow inside?
They will. Being an invasive species they will propagate, readily. This can be done by digging them up, but they root easily from cutting and seed.
As far as growing indoors- This will require very little care from you. Keep them in as much sunlight as possible, and treat them as you would most houseplants.

I was moving a potted morning glory plant and damaged its roots (the trellis came away from the pot and tore it out). I re-potted it and gave it a little sugar water. What else can I do? It is starting to droop. Would adding root hormone to its water help?
There is nothing that you can do to fix the damage. Just let it recover, as doing too much will cause more damage. Luckily in this situation, most morning glories are incredibly invasive. It will likely recover just fine.
