Mulch vs. River Rock: Best Ground Cover Choices for Strata & Commercial Landscaping in BC

For property and facility managers, the choice of mulch vs. river rock for strata and commercial landscaping in BC goes far beyond aesthetics. This decision directly impacts budgets, maintenance schedules, and long-term property value.

While most people know the basic differences between mulch vs river rock, this article focuses on how property and facility managers in Metro Vancouver and the Lower Mainland can make the right choice. Factors like long-term maintenance costs, management efficiency, site conditions such as slopes or sun exposure, and overall plant health all play a role in deciding whether mulch or river rock is the better fit.

Costs & Maintenance: Finding the Right Balance in BC Landscaping

Every landscaping choice has a lifecycle cost, and the best option depends on the unique conditions of each property—there’s no one-size-fits-all solution.

Bark Mulch

  • Low upfront cost, ideal for large, open planting beds.
  • Needs replenishment every 1–3 years as it decomposes and fades.
  • Predictable recurring expense that supports soil health but requires ongoing labour.

River Rock

  • Higher initial cost due to material and installation.
  • Extremely durable, rarely needs replacement.
  • Best for small, high-visibility areas where permanence outweighs upfront expense.

Time & Flexibility: Managing Strata & Commercial Landscapes Efficiently

In commercial and strata landscaping, time is money. Choosing the right ground cover can significantly reduce how often landscapers need to return for maintenance.
Bark Mulch

  • Flexible to move, replace, or refresh as plants mature or designs change.
  • Suppresses weeds initially and enriches the soil as it decomposes, increasing nitrogen levels for healthier plants.
  • Requires periodic upkeep as it breaks down, meaning more frequent maintenance visits.

River Rock

  • Excellent weed suppression when installed with landscape fabric.
  • Minimal upkeep once installed.
  • Less flexible—replanting or redesigning requires more labour.

Case Example: Telus Garden Rooftop Planters

At Telus Garden’s 49th & 50th floor rooftops, the edge planters were originally filled with shrubs that required costly, high-risk maintenance with fall protection.

Our team replaced the plants with landscape fabric and river rock, creating a clean, durable, and low-maintenance solution—perfect for hard-to-access high-rise landscapes.

Site-Specific Risks in BC Landscaping

Drainage & Erosion

Both bark mulch and river rock help manage water flow, but each performs differently:

  • Bark mulch binds together when wet, making it less likely to wash away, especially on slopes or in heavy rainfall areas.
  • River rock allows for more efficient water drainage but is less useful on steep slopes

On steep or erosion-prone areas, a hybrid solution often works best: bark mulch around trees and plant groupings to protect soil, with river rock on exposed edges for stability and aesthetic appeal.

Sun Exposure

  • Bark mulch is ideal for full-sun beds, keeping soil cool and retaining moisture to protect plant roots.
  • River rock can absorb and radiate heat, which may damage plants in hot, exposed areas.

The Hybrid Approach: Best of Both Worlds

The most cost-effective and practical solution for commercial landscaping in BC is often to combine both bark mulch and river rock strategically.

  • River rock works best in high-traffic or hard-to-reach areas, such as parking lot edges, building entrances, rooftop planters, or drainage zones where stability and low maintenance are priorities.
  • Bark mulch is ideal for wide ornamental beds, full-sun planting areas, and zones that require flexibility for seasonal or frequent plant changes, where soil health and plant vitality matter most.

This hybrid strategy delivers the right balance of durability, drainage, erosion control, plant health, and long-term cost efficiency—tailored to the unique landscaping conditions of Metro Vancouver and Lower Mainland.
