How to Choose the Right Landscaping Rock

Think About What You Need

The first step is knowing what you want the rocks to do in your yard.

• For paths and walkways: Pea gravel or crushed granite work best because they pack down well.
• For water drainage areas: River rock is perfect as water flows through it easily.
• For stopping weeds: Lava rock or slate chips block light from reaching weeds.
• For pretty spots: Mexican beach pebbles give a nice look.
• For dry areas: Lava rock and decomposed granite help save water.

Size Matters for Rocks

The size of rocks you pick makes a big difference:

• Small rocks(⅜ inch): Good for paths, like pea gravel
• Medium rocks(1-2 inches): Perfect for water drainage and plant beds, like river rock
• Big rocks(3+ inches): Great as steps or focal points, like flagstone or boulders

Think About Cost

Not all rocks cost the same:

• Best value: Crushed granite and pea gravel cost less, great for big areas
• Save money: Rocks from your area cost less than ones shipped from far away
• Long-term savings: Stone lasts for decades, while wood mulch needs replacing often

Important Things to Think About Before Buying

Stop the Weeds

Always put landscape fabric under rocks. This black cloth stops weeds but lets water through. Without it, weeds will grow through your rocks.

How Deep to Put Rocks

• For ground cover: 2-4 inches deep
• For water drainage: 4-6 inches deep
• For paths: 2-3 inches deep

The right depth keeps rocks from mixing with dirt below.

Think About Cost

• Rocks near you cost less (less shipping)
• Buy in bulk to save money
• Big, heavy rocks cost more to move

Heat and Color

Dark rocks get hot in sun. This can:

• Hurt plants nearby
• Make your yard hotter in summer
• Effect how comfortable your space feels
