Things to Learn About Mulching for Trees

Mulch is a tree's best friend—conserving moisture, suppressing weeds, moderating temperature, and building soil health. Here's what property owners should know.

Types of Mulch

• Organic: Shredded bark, wood chips, compost, manure, pine needles. Decompose, enrich soil.
• Inorganic: Rubber, gravel, lava rock. Long-lasting but don't improve soil.

Benefits

• Weed suppression.
• Moisture retention (critical in drought).
• Water infiltration improvement; reduces runoff.
• Sandy soil water-holding capacity increased.
• Soil temperature stabilization.
• Aesthetic appeal (3–4 inch layer).
• Root zone enrichment as organic mulch decays.
• Protection from mower/trimmer damage.
• Erosion and runoff reduction.
• Disease spore barrier; easier weed removal.

Application Best Practices

• Timing: Mid-spring when soil warms for root growth. Avoid early application (keeps soil cool, delays roots).
• Depth: 2–4 inches over clean, weed-free soil. Never >4 inches.
• Placement: Keep off trunk (prevents rot, rodents). Extend to drip line.
• Texture: Fine mulch—thin layer (compacts, blocks air/water). Medium—2 inches ideal.

Natural Mulch Cycle

Fallen leaves decay into rich, aerated humus—nature's perfect mulch. Most urban soils lack organic matter and suffer temperature/moisture extremes. Mulch bridges this gap.

Mulch correctly, and your trees gain resilience, health, and beauty.
