Why do you put anything down under the pea gravel. If my dogs dig in it for fun it just fills in the hole? Maybe our dirt is different.

I think the landscape cloth is to keep the weeds down. I'm wondering if the weeds would be able to grow with 4 inches of pea gravel on top.

I have pea gravel at the moment, but my old girls don't like to walk on it so they are peeing on the sidewalk. Yuck! My area is small so I'm considering replacing the pea gravel with the new style artificial turf. I know it's pricey, but again, it's a small area.

If I decide to keep the gravel, has anyone used the Sweet PDZ on gravel? If so, how do you apply?

You're right about weeds but we don't get them. Maybe the dogs and gravel kill the weeds.

I use Sweet PDZ and sprinkle it light in the urine area.
