I have a tropical Hibiscus that I tried to save during the cold
winter, but it did not fare too well. The bush is about 3 feet high
and most of its foliage is brown or gone - probably all dead.
However, I do have some small green 'sprouts' showing on the lower
parts of the 'limbs'. I am feeding it Miracle Grow to try to help it.

My question is - should I let it go? Should I prune it? If so, how
much?

Thanks
