Q.Can You Put Real Seashells On Top Of Plant Soil?
dad recently came back from Thailand with lots of amazing seashells I want to put on top of the soil of my houseplants as some sort of decorations, I was curious if the seashells could become damaged because of this because of the water of the soil and how its typically moist, they are seashells like conch, calico scallop, stuff like that. They are currently soaking in hot water and I’m going to be cleaning them thoroughly.

If your soils are, already, moist then I would not put any mulch at all. This will provide breeding grounds for plant pathogens. Instead, I would opt for plants that thrive in moist areas, and leave the soil bare.
Lining the border with them would not be a bad idea, but they will, certainly be damaged by weathering over time.
