Decomposed Granite Paths

With summer here, lots of do-it-yourselfers will be hunting for info on Decomposed Granite.  I have many posts on ‘how-to’ and ‘how-not-to’, including my eBooklets with complete installation information.  I’ve found a few more photos from previous installations of mine in addition to those already on my website.  First some paths:

I would be amiss if I did not show a photo of how you can mix different fines to achieve different DG colors. Areas of the country have different standard decomposed granite colors.  Here in the San Francisco area, most DG is gold fines, and occasionally like some of the photos above you can find grey.  In the photo below we mixed in some black fines to obtain a darker color.  Elsewhere on my website, I have photos of a rock I used that was more pink.  Rock can be used but it must have fines in it.

  1. Hi Leslie,

    I’ve been perusing your blog and website, and downloaded your Designing Your Garden and Decomposed Granite books. They are really helpful, but I’m still not sure what direction to take, and hope you might be able to advise me.

    I live in southern California, near Santa Monica. About ten years ago a landscape designer redid my front path and back yard using a theme of 18″x18″ bluestone squares set on the diagonal, with about 4” between them.

    All the bluestone squares were set on concrete. For small areas outside my front and back doors, bluestone was cut into a lattice and laid in between the squares. For the rest of the back yard, and the front patio, after concrete was poured in the entire area the contractor went through and cut out channels, so that the net result was 18×18 concrete squares, upon which the bluestone was laid using Thinset.

    The area between the squares was filled with sod. Over time, most of the sod died. The front path is extremely shady, as is much of the back yard. A few years ago, I had someone dig up the sod in the back yard and put in DG. They didn’t use DG with stabilizers, so then I had someone else dig out that DG and put in DG with stabilizers. It still didn’t look very good.

    So last fall my handyman dug up the DG in the back, and planted hernaria between the bluestones. He dug up the remaining sod in the front, and planted dwarf mondo grass. The plants in both areas have been slow to catch on. Two factors haven’t helped: one, raccoons keep showing up to dig up the plantings, and, two, although the handyman claimed he brought the soil up flush, either he didn’t or else a lot of it immediately washed away.

    So I want to address this once again. I started reading your website and books thinking that I would once again try DG, maybe both in the back and in the front. But I see that the distance between my stones is way larger than what you recommend. The other alternatives that I see are: (1) pea gravel; (2) the carex texensis / carex pansa that I saw you recommend.

    I guess I could put mortar between the stones but there is no concrete between them for the mortar to sit on top of. Also, then my whole backyard would be a hardscape.

    One frustration of both the sod and the DG has been that my patio furniture does not move well on it, and I have to be careful that in dragging the furniture I don’t pull up the bluestone.

    Attached are photos of my front walkway and the back patio. Also, just to give you the context I’m including a photo of the small areas outside the front and back doors that are fully covered in bluestone.

    Do you have any suggestions?

    Thank you so much.

    -Karen

    (Actually I can’t seem to attach the photos so I am going to email them to you along with this message.)

    • Hi Karen, I see your conundrum.

      There is a lot to address here. You’ve tried a lot too.

      If I understand you correctly, the areas that have soil in-between the pavers actually have concrete underneath? Does that concrete include where the soil is, or just what the paver are laid down on? This is critical for me to understand in order to advise you properly.

  2. Some of your decomposed granite is a really nice gold like at the Getty museum. I just bought some gold decomposed granite and it looks dull brown like mud. Mind you it’s still wet but the dry areas look like dry mud. What’s the story?

    • Depending upon where you live, DG comes in a variety of color choices. In Northern CA bay area, three colors are readily available — gold like the CA hills in summer, gray, or your brown. Did you order it? Or did the landscaper? Sounds like you didn’t make yourself clear on what you wanted. Find out if that yard has other colors available and see if they can swap it out.

  3. I just purchased and read your “Decomposed Granite..:” ebook in anticipation of interviewing landscape contractors to do some work in my backyard. I am in a bit of a quandary with regard to the best solution to pursue and would like your advice. A bit of a background:

    The work will be done on the back 1/4 of my half acre lot, which is in Las Vegas. Currently the back is a mish mash of mature desert trees (I’ve already gotten rid of the incongruous Mexican fan palms) and shrubs interspersed with some ground cover in a number of “beds”. In between all this is a meandering paver path and two patios (of sorts), all constructed of pavers. In fact, aside from multiple islands of vegetation, the yard all hardscape. I recognize that it must have been an expensive undertaking on the part of the previous owner, but it makes for quite the heat sink in the heart of the summer.

    In fact much of the yard’s landscaping is evidence of what happens when an owner’s exuberance is allowed to run uncurtailed by good information. Did I mention that he was an interior designer? To his credit, he did try extend his interior design sense to the exterior, but often without success. The thousands of square feet of pavers are compromised because roots of mature trees are now pushing them up, creating a tripping hazard. I suspect inadequate preparation since the concrete pavers were set in DG and not sand. In an attempt to impose topographical diversity on what is a flat lot, he hauled in and poured what must be copious cubic yards of DG burying the collars of many of the mature trees. I only deduced that that was a problem when we lost 2 mature California pepper trees in a rapid decline. I started researching and taking a good look at the trees in the yard and realized that all of them appear to rise from the DG like telephone poles – no gentle slopes at their base. Arggh.. I love the property and want to create, within reason, a landscape that is respectful of environment and is installed with consideration and without landscaping hubris. At the same time I want to reduce the heat sink effect of the pavers. I already have learned my lesson after the aeoniums I transplanted from San Diego succumbed to the heat.

    All this is preface to explaining my plan. I don’t want to have to haul off so much of the DG to a dump so I thought it best to remove all the pavers from the area in question, remove the DG restoring the natural topography of the yard while giving the trees a better chance of survival, and use said DG to make well-planned and constructed pathways and patios. This would amount to about 150 ft of pathway (4 ft wide) and three patios about 120 square feet each. I know you advise against using DG for patios and “Yes”, my reason for using that material is to control costs. I already have the primary material in hand and would now just need to pay for labor and the necessary sub-base material, the cost of which I hope to offset by selling the pavers. Now to my questions:

    1. Would such a project be one that you suspect can be managed and overseen by a homeowner with an engineering background, with the help of some gardeners to do the heavy lifting? I ask because I am constantly surprised at the high quotes I get from contractors (compared to CA where I moved from).
    2. In the event that the DG is not sufficient, would patios of gravel be appropriate? I may have a problem there as I would now need to find gravel to match the Apache gold DG.
    3. Our soil (if you can call it that) in Las Vegas is extremely hard, consisting of layers of caliche cemented together. Does this mean that I can use less material for the sub-base?
    4. Given my predicament is there any other cost-effective solution you would recommend?

    • 1st let me clarify that DG used exclusively for patio material is a great alternative. I just do not like using a paver/DG combo as high heels, chair legs, etc get caught in between the pavers vs. pavers laid on cement.

      That being said, if you have enough DG, then you could get away with using the Strybing method for your patios and walkway. Alternatively, you could do gravel walkways (as described in my booklet) and DG patio. I doubt you’d be happy with a 120 sq. ft gravel patio.

      You say your ‘soil’ is hard as it is caliche, but without seeing it, I wouldn’t know if your entire base consists of that or would there be ‘holes’ that are sandy. If as described you really have a solid base, then probably you could get away with 3″ of baserock. I am not familiar with the qualities of caliche i.e. how porous, so best to get local advice on that from your local yard.

      There is not reason you cannot used unskilled labor for this job with you supervising. Just make sure your drainage is properly done i.e. crown your patios or drain them to one side.

      Too bad about your Pepper Trees. They are a fabulous tree, live a long time, and have beautiful form. Good luck with your project.

  4. Hi Leslie, Thank you for all your information about decomposed granite here. We are installing a path around our grass and have already purchased the TerraKoat as suggested by a neighbor. Great to see you approve of that product as well! I will be downloading your rebook soon.

    We were hoping to install a lighter color dg, the ginger path fines. However, we did not realize that 1. it’s not a dg and have been told it does not stabilize the same as dg,
    and 2. that it’s hard to find in the winter as quarries stop producing it.
    Wondering if you have a preferred material when it comes to using the TerraKoat?
    We would like to use the ginger fines as we like the color better than the very common gold (which looks brown to me).
    Thank you very much for your time!

    • Hi Erin, although I am not familiar with your ginger fines, I have many times alternative colors. As long as the product contains dust and fines it should work. If you look at the photos, you’ll see a mauve path there which was an ‘experiment’ with fines that I liked and it turned out well. I’ve also mixed the gray with some black fines. The gray is DG while I just used some black fines mixed in and there is a photo of that there too. You can use the regular hardeners with that just like you’d use with DG. I’ve had really good luck as long as the rock product, like I said, is fines with fine dust. I’m sure the TerraKoat would work just as well on your alternative mix as well.
