Mulch: Nature’s Blanket for a Healthier Garden

Why Mulch Matters

Mulch suppresses weeds by blocking light, conserves soil moisture, prevents crusting, moderates temperature, and feeds soil life. Earthworms and microbes break it down into rich humus.

How to Mulch Correctly

1. Apply 3–5 inches (more for coarse materials).
2. Keep mulch away from plant crowns/stems to prevent rot.
3. Water the mulch after spreading.
4. For trees/shrubs, keep mulch 5–10 inches from the trunk.

Organic Mulch Options

• Shredded bark, leaves, straw, grass clippings, pine needles.
• Wood chips/sawdust—add nitrogen first to offset temporary nitrogen draw.
• Cocoa hulls, rice husks, peanut shells, seaweed, corn cobs.
• Compost (the gold standard) mixed with coarse material = “living mulch.”
• Well-rotted manure blended with straw/clippings.

Inorganic & Synthetic Mulches

• Black plastic: excellent weed/moisture control. Cut X-slits for planting; add side slits for air/water drainage.
• Gravel/stone: permanent, good for paths and xeric beds.

Mulch-Mowing: Free Mulch from Leaves

Run a mulching mower over fallen leaves weekly. The shredded mix feeds the lawn, reduces street litter, and builds soil organic matter effortlessly.

Bottom Line

Mulch prepares your garden for drought, flood, freeze, and nutrient gaps. It’s the single most impactful practice for resilient, low-maintenance beds.
