Subsequently, question is, what do you put under decomposed granite? First, the area where the DG paving will be laid will be excavated. Then, a weed barrier, such as landscaping fabric, should be laid down and landscape edging should be installed around the perimeter. Next, the DG will be placed and compacted. At this point, your patio, walkway or driveway is ready to be used.
Is crushed granite the same as decomposed granite?
Also Know, can I plant in decomposed granite?
I am guessing that the looseness of the material is allowing weed seeds to imbed themselves in the DG. At this point, spraying the weeds or pulling them out seems to be the more practical options. The firmer types of decomposed granite, such as with the resin or stabilizers, probably make it more difficult for this to happen. Perhaps this is what is in Paris. or as you guessed, they may have workers just pulling them out all the time!
It reminds me of when I went to England, and the roses at Hidcote (famous English garden) had no blackspot whatsoever. Caretakers can make plants and paving materials look perfect!
Comments for grass and weeds on my decomposed granite
I have used a product called Preen in my planting beds, which is a pre-emergent weed killer. It prevents them from growing. You might try this. it really works.
Thanks for taking the time to consider my question?any insights are much appreciated.
I just now noticed weeds coming in through the DG that is supposedly packed down.
Pacific Palisades contractor Joan Booke has put many of her paths and patios where Bermuda grass lawns used to be, including her own. She doesn’t even bother to kill the lawn with herbicides (though the very cautious might first kill the Bermuda with an herbicide named Roundup), but removes all the turf with about four inches of soil and thatch and replaces it with three inches of D.G. This usually brings the thatch-fattened soil profile back down to where it ought to be. Collins points out another plus: “It’s considerably cheaper than concrete, or just about anything else.” Another contractor suggested that it is three to four times cheaper than concrete.
She likes it so much she used it in her own garden, a ringing endorsement. The natural looking paths wind their way through the garden giving her easy access to all the flowering perennials she grows.
Booke has used it in elegant Brentwood gardens, on Silver Lake terraces and for driveways in Topanga (for driveways, it must be thicker).
There are other colors. In the Central Valley, they use a Sierra gray granite and there is a redder color that comes from Arizona, but in the L.A. area, most of the D.G. is an earthy yellow ocher, the color of our hills.
Booke used Stabilizer on the Topanga Canyon driveway because it wasn’t level. In her own garden, she used plain D.G. brought in by the wheelbarrow load.
