When do I give up on my hibiscus?
I bought 2 hibiscus last year at Home Depot. One is in twisted tree form and the other is a bush. They are both in BIG pots but have died out over the winter due to 30 & 40* weather. I pulled them in a shed during freezing weather but they are very bare. No new leaves and I've had them outdoors for a couple of months now; feeding and watering them.
When should I give up and just throw them away? Is there a chance that they will come back? Don't want to give up if there is a chance for blooms.
Thanks for your time and have a nice day.
