So, can I cover my white stone with Pine Straws or Pine Barks and would they prevent any weeds growing? What's the difference between 14" and 9" pine straws? What would be the best option to prevent weeds if not pine barks/straws? My neighbor installed artificial turf but I really don't like anything artificial and I think they are much more costly..

Cheers!

The reason (IMHO) you have weeds in the stone is all of the dust, dirt, etc, has settled between the stones and provides a place for weeds to go. We have stone also, and when i hand pick the weeds they are definitely ABOVE the "weed barrier". So, what we have done is invest in one of the battery powered weed control sprayers, and I spot weed as necessary, takes about 10 to 15 minutes for all of our garden area, and I refill the battery powered container as necessary.
Also, when we had pine bark, it was 3 to 4 inches, the same for the pine straw. We removed the pine bark as it was dirty as it decomposed, the pine straw seems to be much cleaner.
I actually saw an article within the last 6 months that made a very good case for not using a weed barrier at all.
In any case I would not place either of these items over the rock, O would remove the rock and then install.
Hope this helps.
