Re: Clematis & Rocks

The gravel in question is quite thin. The best the folks at the University could come up with on the problem was that it was probably a response to some environmental stress that resolved before the plant was killed.

Cathy, IMO, the deeper the layer of gravel, the cooler and moister

doesn't do a whole lot; it's better than bare soil but not by much.
A thicker layer of gravel acts like a large rock in keeping
underlying soil cooler - keeping it shaded from the sun.

I don't know but I use a 2" pea gravel mulch in my herb bed because

it

does NOT hold moisture and it gets warm, but that's what the

xeriscape

stuff (lavender, rosemary, thyme, artemisia and ornamental sage)

loves!

Maybe stone is different?

Wish the Bermuda didn't like it as well, but it's less invasive

there than the regular beds...

Could be true. Most examples of rock mulch I have seen were

nowhere

near 2" in depth. Guess I'd need to see a controlled study of some

sort.
