At Canopy Solutions LLC, we believe in nurturing tree health from the ground up. This begins in your soil. Mulching is one of the simplest yet most impactful practices in an arborist’s toolkit—and the benefits speak for themselves.
Why Mulch Around Trees?
1. Retain Soil Moisture & Reduce Water Needs
A 2–4 inch layer of organic mulch can significantly reduce moisture loss, helping trees thrive during dry periods and lowering irrigation needs.
2. Suppress Weeds & Eliminate Competition
By blocking sunlight, mulch limits weed germination and reduces root competition, allowing trees to access more water and nutrients.
3. Regulate Soil Temperature Year‑Round
Mulch acts as natural insulation—keeping soil cooler in summer, warmer in winter, and stabilizing conditions for healthy root growth.
4. Improve Soil Structure & Nutrient Cycling
As mulch decomposes, it adds organic matter to the soil, enhancing texture, microbial activity, and nutrient availability over time.
5. Shield Roots & Trunks from Damage
Mulch zones protect tree bases from lawnmower and foot traffic damage, helping prevent bark injury and root compaction.
Mulch Done Right: Best Practices
- Depth: Apply mulch 2–4 inches deep. Too little offers limited benefit, too much can cause root issues.
- Keep it away from the trunk: Always leave a few inches of clear space at the base of the trunk to prevent rot or pests.
- Extend coverage to the dripline: Ideally, mulch should reach out to the canopy’s edge to fully support the root zone.
- Use organic materials: Natural wood chips, shredded bark, or compost provide long-term soil health benefits.
- Replenish as needed: As mulch breaks down, check annually and top up as necessary to maintain coverage and effectiveness.
Avoiding Common Mulching Mistakes
- Volcano mulching (piling mulch high against the trunk) traps moisture and invites decay. Our team ensures mulch is applied with a proper taper, never against the bark.
- Over-mulching can smother roots and cause oxygen deprivation. We apply mulch at the right depth based on tree species, site conditions, and root zone health.
- Inorganic mulches or dyed materials may look nice short-term but often provide little to no benefit—and can even harm soil health.
Pairing Mulch with AirSpade & Root Zone Treatments
Mulch is even more effective when paired with deeper soil care. AirSpade treatments (such as root collar excavation or soil decompaction) can be combined with mulch installation to stabilize the soil and extend the health benefits. This combination gives trees the best chance at long-term vitality, especially in compacted, urban, or stressed environments.
