Terra Cotta Balls?

Friday, April 03, 2009

I paid a visit to SpaceCraft in Williamsburg (more about that later), and out in their back yard they have a little patch of ground that is covered in tiny terra cotta balls. The owners said the balls were there when they got the space and that they weren't sure what they were meant to be used for. Anyone know what these might be? If they are cheap, they could be a neat alternative to gravel in a patio area.

expanded clay! often used to grow orchids due to their ability to hold a ton of moisture and keep lots of air pockets to serve epiphytic root systems. Whoever put them there was being clever aesthetically, but wow, that is an expensive material to use as a mulch.
