Can Ground Up Corks Be Used As Mulch In A Flower Garden?

Question

My nephew works in Ag (at a winery) and he has bags of used corks. We thought they might make a good mulch if they were ground up before spreading them out on the rose garden.

Answer 1

I did a little research and wine corks can be composted, so I would think you could add it directly onto the soil as mulch (if it doesn't blow away). That is, if it is natural cork and not plastic made to look like cork. Plastic corks can be recycled.
