Angular sand. You can put down a hell of alot more than you think without harming the turf. I don't know how large these areas are in which you refer, but don't be surprised if you have to use thousands of pounds. You will need to backlap the McLane a few times after you have started mowing again.

Where can I buy Angular sand? I went to home depot and I can only find allpurpose sand and play sand.

The All purpose sand may work. See if you can look at the grains through the bag or in spilled areas. You want the sand to be pointy and jagged, not round or smooth. Ideally you would want masonry sand. If you have a truck, you will save a lot of money by just having the masonry yard fill the bed instead of buying dozens of bags from a box store.

Use whatever is cheapest. Be prepared for weeds in the new soil. There are too many reasons for this to be blamed on getting bad soil, but you can get bad soil with nutgrass or bermuda in it. I used all purpose sand in bags from HD for a recent brick project. It is 40% cheaper than play sand.

It probably doesn't matter for this question but I always have to ask. Where do you live in SoCal? As you know the growing conditions at Big Bear Lake are much different than that in Palm Springs or Newport Beach.

Thanks for the info,Ill proly get the truck filled with masonry sand. I cut my lawn short yesterday and the low spots are kinda wide 6x6 some bigger some smaller they don't look that deep maybe 1''or2'' at the deepest.I live in Alta loma(Rancho Cucamonga).Again thanks for the info Ill post some pics asap.
