Decomposed granite, usually shortened to DG, is granite rock that has weathered and broken down over time into a blend of small gravel and fine, sand-like particles. Think of it as a natural crushed material that packs into a firm, earthy-looking surface you can walk on. It is one of the most common materials for garden paths, casual patios, and low-water landscapes in California.
What decomposed granite actually is
Granite is a hard rock, but exposed to weather over a long time it crumbles. What is left is a mix of tiny stones and gritty fines in the same color family as the parent rock. The most common landscape grade is called 1/4-inch minus, which means the largest pieces are about a quarter inch and everything down to fine dust is included. Those fines are what let DG compact and lock together instead of staying loose like round pea gravel.
Because it is a natural product, no two yards of DG look exactly alike. Color, grit size, and how tightly it packs all depend on the source quarry.
Where people use it
DG is flexible, which is why you see it almost everywhere outdoors. Common uses include:
- Garden and walking paths
- Casual patios and seating areas
- Joint filler between flagstone, pavers, or steppers
- Dog runs and play areas
- Xeriscape and drought-tolerant planting beds
- A natural mulch-style topping around plants and trees

The pros and cons
DG earns its popularity, but it is not the right answer for every spot. Here is the honest tradeoff.
| Pros | Cons |
|---|---|
| Natural, earthy look that blends with most homes | Loose DG can track onto shoes and indoors |
| Permeable, so water soaks in instead of running off | Can erode or wash in heavy rain or on slopes |
| Affordable compared with poured concrete or pavers | Needs edging to hold its shape |
| Good fit for drought-friendly, low-water yards | Needs an occasional top-up as it settles or thins |
Loose DG vs stabilized DG
You will buy DG in one of two forms. Loose DG is the natural material, compacted on its own. It is cheaper and works well for casual paths and beds where a little movement is fine.
Stabilized DG has a binder mixed in so the surface sets firmer, sheds less, and tracks less. It costs a bit more and takes more care to install, but it holds up better on main walkways and high-traffic areas. We break down the difference in detail in what is stabilized decomposed granite, and you can browse the binder products in our stabilizers collection.
Colors
DG comes in several color families depending on where it was quarried, from golds and tans to browns, reds, and grays. Keep in mind that DG usually reads lighter when dry and darker when wet, and most colors weather a little lighter over time. The safest way to pick is to look at a physical sample in your own yard light rather than trusting a screen.
How decomposed granite is sold
Most suppliers, including us, offer DG a few ways so you can match the order to the job:
- Samples for choosing a color before you commit. Order samples here.
- Bags for small repairs, touch-ups, and tiny areas.
- By the ton for typical paths, patios, and beds.
- Bulk for large jobs and driveways, with delivery or pickup.

Frequently asked questions
What grade of decomposed granite should I buy?
For most paths, patios, and beds, 1/4-inch minus is the standard choice because the fines let it compact into a firm surface. Larger grades stay looser and do not pack as well.
How deep should decomposed granite be?
A finished depth of about 2 to 3 inches, compacted in layers, works for most walking paths and patios. Run your measurements through the coverage calculator for an exact amount.
Does decomposed granite get muddy?
Because DG is permeable, it drains rather than puddling, but loose fines can soften in heavy rain. Good edging, a proper base, and stabilized DG all reduce that in wetter or higher-traffic spots.
Is decomposed granite the same as crushed granite?
They are close but not identical. Crushed granite is mechanically crushed and tends to be more angular and uniform, while decomposed granite is naturally weathered and includes more fine material that helps it pack.
