Keeping landscape rock looking new comes down to rinsing off dust, clearing leaves before they stain, pulling weeds early, and topping up thin spots once a year. Rock is low maintenance, not no maintenance, and a few minutes here and there keeps it sharp for a decade or more.
Why rock needs any maintenance at all
Rock does not rot, fade fast, or need water, but it does collect things. Dust dulls the color, leaves break down into organic matter that feeds weeds, and foot traffic thins out paths over time. The good news is every one of these is easy to stay ahead of if you do it on a schedule instead of waiting for the yard to look tired.
The maintenance schedule
| Task | How often |
|---|---|
| Blow or rake off leaves and debris | Every few weeks in fall, monthly otherwise |
| Rinse dust off with a hose | Twice a year, or after dust storms |
| Pull or spot-treat weeds | Monthly in the growing season |
| Check and refresh edging | Twice a year |
| Top up thinned or low areas | Once a year |
| Re-level and recompact DG paths | Once a year, or after heavy use |
| Inspect and patch landscape fabric | Yearly, when you spot weeds pushing through |
How do I get the color back after it goes dull?
Dust is almost always the culprit. Set a hose nozzle to a firm spray and wash the rock down, working from one end to the other. River rock and pebbles brighten the most because their smooth surface holds less grime. For a deep clean on a small area, you can rinse and rake at the same time to bring buried clean stones to the surface.
What is the best way to handle weeds in rock?
Pull them while they are small and the roots come out easily. Weeds in rock usually grow in the organic layer that builds up on top, not in the soil below, so a good blow-out of leaves and debris each fall removes most of their seedbed. Quality landscape fabric under the rock stops the rest. When you see weeds pushing through, that is your sign the fabric needs a patch.
Why do my decomposed granite paths develop low spots?
Foot and wheel traffic pushes DG outward, leaving shallow dips that puddle. Once a year, rake the loose material back into the low spots, dampen it, and tamp it down. If your path was installed with a stabilizer, it holds its shape much longer and needs this far less often. Stabilized DG is worth considering for high-traffic paths.
Tools that make it easier
You do not need much: a leaf blower or stiff rake, a hose with an adjustable nozzle, a hand weeder, and a tamper for DG paths. A bag or two of fresh rock on hand lets you top up thin spots the moment you notice them instead of letting them spread.
Frequently asked questions
How often should I clean landscape rock?
Blow or rake off debris every few weeks in fall and monthly the rest of the year. Rinse dust off with a hose about twice a year, or whenever the color looks dull.
Will pressure washing damage my rock?
A regular hose with a firm nozzle is safer and usually enough. Pressure washers can blast smaller stones out of place and tear landscape fabric, so keep the pressure moderate and the nozzle moving if you use one.
How do I stop weeds from coming back in rock?
Pull weeds while small, clear out the leaf and debris layer they root in, and keep quality landscape fabric intact underneath. Patch the fabric whenever weeds start pushing through.
How much rock do I need to top up a thin area?
Most refreshes only need a bag or two per area. Measure the low spot and use our coverage calculator to estimate, then order a sample or bag size to match your existing color.
