Another Pea Gravel Potty Question
We are having a landscape company re-grade and sod our small yard, and I'm going to have them put in a circular pea gravel area for the dog potty just off the driveway. My breeder has an awesome large gravel area off her deck for her dogs, but we don't have that much space, it'll be maybe 6 feet in diameter. They used a few inches of larger rocks as a base (egg to tennis ball sized) and then about 3 inches of round, smooth pea gravel on top, no landscape fabric underneath.
The guy who was out her for an estimate yesterday said that pea gravel does get mushy underfoot if it's too deep, but he didn't think the larger rocks underneath were necessary, that just a few inches of pea gavel and some porous landscape fabric underneath would do it. As far as I know, I'll have just one dog using it (and probably a few squirrels), but it seems like good drainage is still important.
For those of you that have used gravel, what depth did you put the gravel to, is it a firm enough surface, and do you think digging down deeper and using the larger rocks below is necessary for stability and drainage? It seems to me like that would firm up the base and the pea gravel would kind of lock in between.
Also, what type of product do you use on it to clean it, if anything? I'm thinking some sort of enzyme in the warmer months.
If the gravel doesn't work out for any reason, we'll try some fake turf in there.
