Summer is the season of stress for both plants and landscapers. High temperatures, dry conditions, and intense sun can damage even the most well-designed landscapes. Fortunately, there’s one simple and effective strategy to protect your investment: mulching.
This post covers essential summer mulching tips to help preserve moisture, control weeds, and reduce soil temperature. Whether you manage commercial properties or oversee large residential developments, smart mulching will save time, water, and money.
Why Mulch Is Essential During Summer
Mulch is more than a finishing touch. During summer, it acts as a barrier between the soil and harsh environmental conditions. Here’s why mulching is especially important this time of year:
-
Reduces moisture evaporation caused by direct sunlight
-
Stabilizes soil temperatures to protect roots from heat
-
Suppresses weeds that compete for water and nutrients
-
Minimizes crusting and runoff after summer rain
-
Adds organic matter to the soil as it decomposes
According to Colorado State University Extension, mulching can reduce moisture evaporation from soil by up to 70 percent, depending on the mulch type and how thickly it’s applied. That’s a major benefit during dry summer months or when watering restrictions are in place.
Choosing the Right Type of Mulch for Summer
Not all mulch performs the same in summer heat. The type of mulch you choose should align with your project goals, whether it’s moisture retention, soil improvement, or visual appeal.
Recommended Bulk Mulch Types:
-
Natural Hardwood Mulch – A durable, classic choice that holds up well in sun and rain. It also provides excellent weed control and long-lasting coverage.
-
Compost Mulch – A blend of partially decomposed organic material that improves soil health while regulating temperature and moisture.
-
Pine Bark Mulch – Works well for acid-loving plants and decomposes more slowly than other types. Suitable for large decorative beds.
-
Shredded Mulch – Offers better coverage and stays in place during wind and rain. Ideal for slopes or exposed areas.
Avoid using rock or rubber mulch in hot climates. These materials trap heat and do not contribute to soil health.
When Should You Apply Mulch in Summer?
The best time to mulch is in late spring or early summer before the hottest weather begins. However, if it’s already mid-summer, it’s still worth applying mulch to protect your landscape.
Here are a few tips for mid-season mulching:
-
Water the soil thoroughly before applying mulch
-
Never mulch over dry soil since this can trap dryness in
-
Apply mulch after a rain or early in the day for better soil contact
Working in the early morning or late evening is safer and more effective when applying mulch during peak summer temperatures.
How Much Mulch to Apply
For most landscaping applications, a depth of 2 to 3 inches is ideal. Less than that won’t provide enough insulation, while too much mulch can prevent water and air from reaching plant roots.
Coverage guidelines:
-
2 inches covers about 162 square feet per cubic yard
-
3 inches covers about 108 square feet per cubic yard
To estimate how much mulch you need, use this formula:
Square footage × depth (in inches) ÷ 324 = cubic yards needed

Common Mulching Mistakes in Summer
Avoid these common errors when mulching during hot weather:
-
Piling mulch around tree trunks (also called “mulch volcanoes”)
-
Using raw mulch that hasn’t decomposed properly
-
Applying mulch over dry or compacted soil
-
Ignoring weather forecasts before scheduling delivery
-
Over-mulching, which can suffocate plants or attract pests
If you’re unsure which mulch is right for your site, your supplier can help guide the decision based on your goals and environment.
