🪵 Organic Wood Mulch
Shredded Hardwood Bark
The most popular landscape mulch — shredded bark from hardwood trees that knits together and stays in place. $30–$45/cubic yard. Dark brown to black color. Stays put on slopes because shredded fibers interlock. Decomposes over 2–3 years, adding organic matter to soil. Apply 3 in deep. The workhorse mulch for garden beds.
Arborist Wood Chips (Free)
Fresh wood chips from local tree services — often available for free via ChipDrop.com or calling arborists directly. $0 (free). Mixed species, mixed chip sizes, may include leaves. Excellent for paths, around trees, and in naturalistic gardens. Break down over 1–2 years, feeding soil biology. The best free mulch available anywhere.
Cedar Mulch
Shredded or chipped cedar with natural oils that resist insects and decay. $35–$55/cubic yard. Reddish-brown color that fades to silver-gray. Natural insect-repellent properties from cedar oil. Lasts 3–4 years before needing refresh. Pleasant cedar fragrance. Best for foundation beds and areas near the house.
Pine Bark Mini Nuggets
Small pine bark pieces (1–2 in) for a uniform, neat look in formal garden beds. $35–$50/cubic yard. Stays on top of soil without breaking down quickly. Slightly acidic — good for azaleas, rhododendrons, and blueberries. Light reddish-brown color. More formal than shredded bark. Floats in heavy rain — not ideal for slopes.
Pine Straw
Dried pine needles — the traditional mulch of the American South. $4–$7/bale (covers ~50 sq ft). Lightweight, easy to spread, stays in place on slopes. Mildly acidic. Extremely popular in the Southeast US where pine trees are abundant. Natural, informal look. Excellent for paths through woodland gardens.
Leaf Mulch (Shredded Leaves)
Autumn leaves shredded with a mower and spread 3–4 in deep as garden mulch. $0 (free from your own yard). The best free mulch for building soil health — shredded leaves decompose in one season, adding humus and feeding soil organisms. Shred before applying — whole leaves mat and smother. Every gardener's secret weapon.
🪨 Rock & Stone Mulch
River Rock Mulch
Smooth, rounded river rocks (1–3 in) in beds for a permanent, no-decompose mulch. $40–$80/cubic yard. Never needs replacing. Does not add nutrients to soil (use landscape fabric below). Excellent for drainage areas, around foundations, and in xeriscape designs. Gray, tan, or mixed natural tones.
Pea Gravel Mulch
Small, rounded gravel pieces (3/8 in) for a clean, modern look. $30–$50/cubic yard. Works as both mulch and a walking surface. Extremely low maintenance. Popular in Mediterranean, modern, and Japanese garden styles. Plant through it in pockets. The most versatile rock mulch.
Decomposed Granite (DG)
Crushed granite that compacts into a firm surface — mulch and pathway material combined. $30–$50/cubic yard. Gold, tan, gray, or red tones depending on granite source. Compacts firm when stabilized. Excellent for paths, under gravel gardens, and as a lawn replacement. Apply 2–3 in over landscape fabric.
Lava Rock Mulch
Lightweight volcanic rock in red or black for a dramatic garden mulch. $35–$60/cubic yard. Excellent drainage properties. Does not decompose or fade. Very lightweight — won't compact soil. Red lava rock is striking in desert and modern gardens. Black lava rock creates dramatic contrast with green plants.
White Marble Chip Mulch
Bright white marble chips for a formal, elegant landscape mulch. $45–$75/cubic yard. Reflects light and brightens shady areas. Can raise soil pH — avoid around acid-loving plants. Very formal appearance. Popular in Mediterranean and coastal gardens. Glaring in full sun in hot climates — use where it won't create heat reflection.
Slate Chip Mulch
Flat, angular slate pieces in blue-gray or black for a sleek, contemporary mulch. $50–$80/cubic yard. The most sophisticated-looking rock mulch. Flat pieces stack and stay in place on slopes. Blue-gray color coordinates with modern and industrial gardens. Does not fade. Expensive but permanent.
🌱 Living & Green Mulch
Creeping Thyme Mulch
Low-growing thyme groundcover that forms a living mulch carpet between plants and along paths. $2–$4/plant. Fragrant when walked on. Tolerates foot traffic. Purple flowers in summer attract pollinators. Excellent between stepping stones and as lawn edge replacement. Suppresses weeds while adding beauty and scent.
White Clover Living Mulch
Dutch white clover seeded between crops or landscape plants as a living, nitrogen-fixing mulch. $5–$15/lb of seed. Fixes atmospheric nitrogen into soil — free fertilizer. Stays under 6 in tall. Suppresses weeds, retains moisture, feeds pollinators. Increasingly popular as a lawn alternative and garden mulch.
Sedum Groundcover Mulch
Low-growing stonecrop sedum planted as a living mulch that suppresses weeds and tolerates drought. $2–$3/plant. Nearly maintenance-free. Spreads to fill gaps. Tolerates poor soil, full sun, and complete drought. Turns red and orange in fall. The most forgiving living mulch for hot, dry conditions.
Moss Mulch (Shade Areas)
Encourage moss growth as a living mulch in shaded, moist areas. $0–$50. Transplant moss from other parts of your property. Moss thrives in shade with acidic, compacted soil. Creates a velvet carpet that suppresses weeds and retains moisture. Japanese moss garden aesthetic.
Straw Mulch (Vegetable Gardens)
Clean wheat or oat straw applied 4–6 in deep around vegetable plants. $5–$10/bale. The traditional vegetable garden mulch. Keeps soil cool, retains moisture, suppresses weeds, and keeps fruit off the ground. Use straw (stem), not hay (which contains weed seeds). Remove or till in at end of season.
Compost Top-Dressing
A 1–2 in layer of finished compost applied on top of soil as a mulch and slow-release fertilizer. $30–$50/cubic yard. The most nutritious mulch — feeds plants, improves soil structure, and supports soil biology simultaneously. Best for vegetable gardens and perennial beds. Doesn't look as tidy as bark mulch but grows better plants.
🎨 Colored & Specialty Mulch
Black Dyed Mulch
Hardwood mulch dyed black for a dramatic, high-contrast look against green plants. $35–$55/cubic yard. Most popular dyed mulch color. Creates strong visual contrast. Fades to dark gray over one season. Non-toxic vegetable-based dyes are standard. Apply 3 in deep. Refresh annually for consistent color.
Red Dyed Mulch
Hardwood mulch dyed reddish-brown for a warm, traditional landscape look. $35–$55/cubic yard. The second most popular dyed mulch. Matches brick and terracotta architecture well. Fades faster than black dye. Apply fresh each spring for consistent color. Popular in Southern and traditional landscapes.
Rubber Mulch (Playground)
Recycled tire rubber mulch for playground areas — cushions falls and never decomposes. $80–$120/cubic yard. ASTM-approved playground surface. Cushions falls from up to 12 ft. Does not decompose, attract insects, or need replacing. Heavy — stays in place in rain and wind. Not for garden beds — for play areas only.
Cocoa Shell Mulch
Chocolate-scented cocoa bean hulls as an organic garden mulch. $6–$12/bag. Rich brown color and genuine chocolate aroma. Lightweight. Decomposes quickly (1 season). CAUTION: toxic to dogs if ingested (contains theobromine). Use only in dog-free areas.
Glass Mulch
Tumbled recycled glass in blue, green, amber, or clear as a decorative mulch. $15–$30/bag. A modern art-garden accent mulch. Tumbled smooth — no sharp edges. Reflects light beautifully. Use in small accent areas, containers, or around specimen plants. Not for large-scale beds.
Mushroom Compost Mulch
Spent mushroom farm substrate — a nutrient-rich, dark compost used as mulch. $20–$35/cubic yard. Very high in organic matter and nutrients. May be high in salts — avoid on salt-sensitive plants. Excellent for heavy clay soil improvement. Apply 2–3 in as mulch or mix into soil before planting.

❓ Frequently Asked Questions
How deep should mulch be?
3 inches deep is the standard for most landscape mulch — deep enough to suppress weeds and retain moisture without smothering plant roots. Never exceed 4 inches. Around tree trunks, keep mulch 3–6 inches away from the bark (no volcano mulching). Pull mulch 1 inch away from plant stems to prevent rot.
What is the best low-maintenance mulch?
Rock mulch (river rock, pea gravel, lava rock) is the most maintenance-free — it never decomposes and rarely needs refreshing. Cedar mulch is the best organic option for low maintenance — its natural oils resist decay and insects for 3–4 years. Rubber mulch in play areas lasts indefinitely.
Is dyed mulch bad for plants?
Modern dyed mulch uses vegetable-based dyes (carbon black for black, iron oxide for red) that are non-toxic to plants and soil. The dye itself is safe. However, cheap dyed mulch is sometimes made from recycled CCA-treated lumber, which can contain arsenic. Buy from reputable sources that use untreated wood. Natural mulch avoids this concern entirely.
How much mulch do I need?
To cover 100 sq ft with 3 inches of mulch, you need approximately 1 cubic yard. Formula: (area in sq ft × depth in inches) ÷ 324 = cubic yards needed. A typical front yard foundation bed (200 sq ft) needs about 2 cubic yards. Bulk delivery saves 50–70% vs buying bags — break-even point is usually around 3 cubic yards.
What mulch is best for a vegetable garden?
Straw is the traditional vegetable garden mulch — 4–6 in deep. Compost top-dressing (1–2 in) is the best for soil health. Shredded leaves (free) are excellent and break down quickly. Avoid dyed mulch in vegetable gardens. Never use rubber mulch near edibles. Pine needles work well for strawberries and blueberries.
Should I put landscape fabric under mulch?
Under rock mulch: yes — fabric prevents rocks from sinking into soil. Under organic mulch: no — fabric blocks the beneficial decomposition cycle where organic mulch feeds soil biology. Organic mulch works best when it's in direct contact with soil, decomposing into the surface layer and being replenished on top.
