My son wants a large, showy, hibiscus. I bought a large plant in a three gallon pot.

Since he is living in a rental, I suggested to pot it in a much larger pot. Now, how should he safeguard it during the winter?

With hostas, I turn the pit on its side sometime in late November. Please advise how to treat the newly potted hibiscus.

Thank you.

I need your advice. Will a potted hardy hibiscus survive the winter?

well I left one potted last winter and it did ok. The yr before a potted one died. so dunno. I did pile a bunch of mulch up around the pot. Trick is well drained soil-roots do not like to freeze really wet, frozen water over crown area will kill it. Other thing is they do like water so during warmer spells if it is dry out do water some.

We rarely get long freezing periods, but mine have sat outside all winter in trays filled with water. One of mine in the ground stays underwater all winter. Of course most of mine are straight species, not cultivars.

They may live out in the water more-so in zone 9 vs zone 5. We get long frozen periods, maybe that is why. I am sure the species are more hardy they usually are. I did grow a hibiscus in a pond and it did great for me, but pulled out and heeled into dirt/mulch for the winter.
When it was in the pond, it had no soil, just bare roots in water. Used a rock to weigh it down so it wouldn't float around.

Gerry, Hardy Hibiscus go dormant and die back to the ground in winter. It would be best if you can place it in a cold location that does not freeze like a indoors or a garage. It won't need light since it is dormant, just keep it were the temps won't go above mid 60's are freeze. Don't allow it to dry out completely.
