Question 1

How deep should decomposed granite be?

Accepted Answer

•

The depth of your decomposed granite depends on its intended use, but around 3 to 4 inches is the most common depth. Driveways that need to support a lot of weight should be at a depth of no less than 6 inches. Walkways that won’t see a lot of weight but lots of foot traffic should be built at a depth of 3 to 4 inches, and patios should also be between 3 and 4 inches deep.

Question 2

Do you need landscape fabric under rubber mulch?

Accepted Answer

•

Yes, you need to use landscape fabric under your rubber mulch. Rubber mulch doesn’t decompose, so putting landscape fabric down can work as a barrier between your mulch and soil, preventing your mulch from mixing with your soil and leaching chemicals like aluminum, cadmium, and copper into it. Also, since weeds can occasionally get through rubber mulch, using landscape fabric as a second form of protection can increase its effectiveness.

Question 3

How do you calculate the amount of gravel needed for a driveway?

Accepted Answer

•

No one likes running out of materials during a project, so calculating the right amount of gravel needed for your driveway is an absolute must. Multiply your driveway’s length by width by the depth of the gravel (in feet). For gravel depth, convert to a decimal (i.e., 4 inches is 0.33 feet). This will give you the cubic feet of material that you need.

If you’re looking for cubic yards, divide that above number by 27.

Question 4

When should mulch be laid?

Accepted Answer

•

There are two main times of the year to spread mulch—mid-spring and late fall. Spring mulching protects new seedlings as the soil warms up and the rainy season begins. Fall mulching insulates the soil and regulates its temperature as the first frosts arrive.

Question 5

Do weeds grow in decomposed granite?

Accepted Answer

•

Yes, weeds can still grow in decomposed granite. If properly compacted, it can act as a good weed suppressant, meaning you’ll only pull weeds occasionally. But no ground cover is completely weed-proof. To further prevent weeds, you can try spraying your decomposed granite with distilled white vinegar.
