Mulch Types

1. Organic Mulch

Organic mulch is made from natural materials that break down over time, enriching the soil. Common options include:

• Bark mulch – Long-lasting and attractive, ideal for flower beds and borders.

• Shredded wood – Great for moisture retention and weed suppression.

• Compost mulch – Adds nutrients quickly, perfect for gardens.

Pros: Improves soil health, natural appearance

Cons: Needs periodic replenishing

2. Inorganic Mulch

Inorganic mulch doesn’t decompose and is mainly used for decorative or functional purposes.

• Rock or gravel – Ideal for xeriscaping and low-maintenance areas.

• Rubber mulch – Durable and great for playgrounds.

• Landscape fabric with cover – Prevents weeds and erosion.

Pros: Long-lasting, low maintenance

Cons: Does not enrich soil

3. Bark Mulch in Utah

Bark mulch is especially popular in Utah for its rich color, durability, and weed-suppressing qualities. However, it works best when combined with proper irrigation to prevent drying out in Utah’s hot, dry summers.

Benefits of Mulch

• Moisture Retention – Reduces evaporation, meaning less watering.

• Weed Control – Blocks sunlight to stop weed growth.

• Temperature Regulation – Protects roots from extreme heat and cold.

• Erosion Prevention – Keeps soil in place during wind and rain.

• Visual Appeal – Gives beds a clean, finished look.

How Much Mulch Do You Need?

The general rule:

• 2–3 inches for flower beds and gardens

• 3–4 inches for pathways or heavy weed-prone areas

Measure your bed’s length, width, and desired depth, then use a mulch calculator (like the one on our site) to get the right amount. Ordering too much can waste money—ordering too little leaves gaps.

When to Mulch in Utah

Utah’s dry climate and seasonal extremes mean timing is important:

• Spring: Mulch after soil has warmed to lock in moisture before summer heat.

• Fall: Mulch before the first frost to protect roots during winter.

• Avoid late winter mulching as it can delay soil warming in spring.
