Seashells safe to use as groundcover?

Hi,
I have a small area, about 4 feet by 4 feet. I'd like to put a couple of small ornamental grasses there and to cover the soil with seashells, such as big clam shells and other smaller shells.
Do you think the seashells will cause any problems in the soil, such as leaching out too much salt? Should I put wood mulch down, then cover with shells?
Thanks, Libby |

| Should be perfectly safe. The shells do not contain salt but calcium. Over many years, they will degrade and slowly leach calcium which may make the soil slightly alkilin, but no cause for alarm. |

| Libby, I have a small area of seashell mulch. I'd suggest you put some sort of barrier down before applying the shells. They are a pain to weed between. |

| Even with the barrier, there will be weeds. The leaf litter and dust will eventually create soil suitable for some weed or another. |
