Will Scotts Turf Builder Weed and Feed 3 recognise Diamondia as a grass or a weed?

I have a patio of irregular flagstones with the ground cover called diamondia filling the cracks. It is very beautiful but it is being invaded with dandelions and some thistles. If I put STB on the diamondia will it see it as a grass (and therefore leave it alone) or as a weed (since it is not a regular grass).

Answer:

Diamondia is a form of groundcover and Scotts Turf Builder Weed and Feed 3 is only for use on turfgrass.  It could injure the groundcover and would be best to avoid any applications to the area and keep a few feet away when applying.  It would be best to handpull weeds from the path area where the Diamonida is growing.
