Hibiscus and rain

[Aforek]

Hello

I have a hibiscus of about 2 meters, a lot of red flowers; it is at the bottom of my garden, not far from a paddy field; now, the rice field, because of the rains, is a huge basin, and the water arrives in my garden and the hibiscus already has its feet in the water I fear he drowned; it is too big for me to put it in a pot; I have already had a magnificent Chinese magniolia which stayed two weeks with its feet in the water, and it ended up dying (all its leaves turned yellow and it ended up having none at all); what can I do for my hibiscus?

this year, it's raining very much and we are only at the beginning of September, it's not finished

thank you

Take some cuttings. They can grow to 2 metres in about 2 years. Then you have spares.
