What's up (or not) with my clethra?
I planted a few clethra Ruby Spice in a very wet, half shade/half sun garden about two years ago.
They are growing nicely, but two of them are laying flat on the ground. I know one of them got hit with a branch this winter - I had thought it was a goner but it continues to grow, laying on the ground. (I have to keep re-propping it up.) The second one, I found no apparent damage to, but it also is growing wonderfully; its just laying on the ground too.
Are these plants known to be floppy or top-heavy? They don't seem to have more growth on top, at least not enough to make it topple. Is the soil too wet? Not enough sun? All I read on them says they like wet soil and part shade.
I'm stymied, and not sure what to do other than to keep propping them up. Any thoughts?
