Yes, and you must water daily since potted soil dries a lot faster than in the ground. Any hosta planted in the sun needs daily watering.
Feed it with high nitrogen.
I have not found anything that I cannot grow in a pot and a lot of times better. Every hosta I get I start them in pots in the sun to get better growth. I lost a few so I started laying them on their side in the winter and that worked. Are you sure you can not just lay it on its side? There is no lifting involved just pushing.
Maybe it is why I have good success with growing plants in pots I never use small pots. I love huge pots I can plant up like a garden.
Do you get a lot of thaw and rain in the winter then freezes? That is my problem of hosta deaths. I get a lot of rain and then we freeze so it kills the crown. If you cannot turn it over can you go out after everything freezes and put some leaves in a pot and turn it over the crown of the Hosta put a brick or something heavy on top of the pot so it does not blow off? If you do not have a brick maybe take one of those dry cleaner hangers open it up and make like a dome over the pot to keep it from blowing away.
It was the crown that was rotted after the winter is what killed my Hosta in the pots.
