Advice on Old Woody Hibiscus
Hey all. Forgive me if I come off sounding really ignorant, I'm only just now studying up on Hibiscus and I don't have a lot of personal experience (yet) to work from.
On the border of my property, I have an old Hibiscus, President, as best I can tell. It had to be 5+ years old when I moved in. (all photos were taken this morning, 5/17/13)
Around Sept/Oct I pruned it back some, taking off most in-growing branches, cutting back on the legginess, and trying to promote some additional growth, but I wasn't sure how hard to prune, or how successful I would be, thanks to things like this:
Now spring is in the air, and I came back for a second look, and I don't like what i see.
The old girl still has life in her, but I was hoping for some advice.
- Is it worth hard pruning back to a foot or so in height and starting fresh?
- If so, how do I deal with horizontal stems growing from the ground?
- The bug situation, will it get better or worse if I cut back severely?
- I know it would be easier to start over with a fresh plant, but is there any benefit to trying to salvage this one?
Any help would be greatly appreciated.
