The darker gray and black tones of the home are softened by the shade and texture of the DG used. 

2-5. Cohesive co-existence

For a makeshift patio, you can set a DG space at the center and enclose it with stone edging. Around it, spread mulch to layer the terrain. The use of river rocks and stone pavers to make it a highlighted spot is also a fine touch like this one.

Speaking of geometric lines, you can also infuse this with slabs of grass in a pattern that resonates concrete walkway slabs. For the ground cover, which gives the grass a standout look, you should use lighter toned DG. 


For more handy information about how to work with decomposed granite in landscaping, here are some FAQs that you should know of. 

What is decomposed granite?

This material is often confused for gravel, but it is finer in texture and is generally more stable than gravel. It is derived when rocks such as granite or igneous rocks reach their weathering point. They come in green, red, black, white, and gray colors.

How long does it take for decomposed granite to harden?

It takes 3-4 days for decomposed granite to harden. As such, the whole installation process could take more than a week from preparation to pouring. 

How much is decomposed granite? 

On an average, using decomposed granite would cost you at just $40-50 per cubic yard. This is the reason why it is usually used as edging for more expensive concrete pavers and for large ground covers. 

Does decomposed granite get muddy?

While it is the least expensive flooring for patios and more, it could get muddy and mushy when moisture penetrates the surface. As such, it needs to be reinforced during the rainy season and during winter. 

Will weeds grow through decomposed granite?

Yes. It is not a perfect material for a wide range of natural elements. Rain, sun, and other natural forces could still encourage weed growth. 


Decomposed granite, without doubt, is one of the best gravel and dirt alternatives for landscaping at the moment. Aside from the glaring cost-efficiency, it is also versatile for any landscape design, lasts long and is fairly low maintenance.
