Will hostas thrive in a big pot?

They should do well there. They like the shade, plus being on a patio the slugs should leave them alone.

Hostas like a permanent spot. If your pots are huge enough to support their root systems over the winter (and the winter is not too severe) you should have a crack at them thriving. Personally, I wouldn’t bet the farm on it.

Central Ohio. I have had hostas that did great in the ground at another place. It’s the pot I am wondering about.

I was thinking put them against your house foundation and mulch them well before winter hits.

They will do fine. You might have to take them in if it gets below freezing in the winter.

Make sure the pot is big enough. The variety of hosta that it is will determine the size. Water every day when it’s hot and fertilize occasionally because watering leaches out the nutrients. Hostas are very easy to grow. If it gets too big for your container you can divide it easily and put it into 2 pots.

Here’s an interesting site that describes how to grow hostas in pots. It is labor-intensive because, apparently, you cannot leave them out during the winter.

“Like all hostas, container hostas need to go through dormancy in the winter. Containers cannot be left outdoors for the winter or the plants will rot. In winter the containers should be placed in a location away from overhead moisture. An unheated garage or porch is ideal.

When plants begin to grow in the spring, they should not be placed outside until danger of frost has passed. You can put them outside during the day, or when temperatures are above freezing, but the plants should be brought in if frost is forecast. Remember, water expands as it freezes which can cause pots to break or hostas to heave from the soil.”
