When you think about mulch or compost, you probably envision healthy gardens, thriving landscapes, and nutrient-rich soil. But behind the scenes, crafting high-quality mulch and compost is a science—and one of the most important (but least visible) parts of that process is temperature control.

At Hansen’s Tree Service, we take this responsibility seriously. That’s why we use advanced temperature monitoring systems that send real-time data directly to our production team, ensuring our mulch and compost reach—and maintain—the critical temperatures needed to eliminate unwanted pests, weed seeds, and harmful pathogens.

Here’s why temperature monitoring isn’t just a good practice—it’s essential.

The Science Behind It: How Heat Cleans Compost and Mulch

Organic materials, whether wood chips, leaves, or green waste, naturally decompose through microbial activity. As bacteria and fungi break down the material, they generate heat. When conditions are right, this microbial activity can drive the internal temperature of a mulch or compost pile into the ideal range for sanitization.

Research shows that to effectively kill most common weed seeds, insects, and plant pathogens, compost piles must maintain internal temperatures of:

• Between 131°F and 170°F (55°C–77°C) for at least three consecutive days, according to the U.S. Composting Council.
• At least 140°F (60°C) for several days to ensure destruction of tougher weed seeds and many soil-borne pathogens.

If piles don’t reach these temperatures—or if hot spots are inconsistent—it leaves an open door for contaminants to survive and end up in the final product, defeating the purpose of using mulch and compost to improve your soil.

Why Real-Time Temperature Monitoring Makes a Difference

Traditional composting often relies on periodic manual checks with a long-stemmed thermometer, but that approach can miss fluctuations between readings. At Hansen’s, we use a temperature monitoring system that delivers real-time data on every batch we produce. Our system alerts our team if temperatures fall outside the target range, allowing immediate adjustments like turning the piles or adjusting moisture levels.

This technology ensures:

• Even Heating: All materials reach pathogen-killing temperatures, not just the center of the pile.
• Consistent Quality: Every batch meets our high standards before it goes out the door.
• Environmental Responsibility: By producing contaminant-free compost and mulch, we help prevent the spread of invasive species and plant diseases into gardens and landscapes.

How This Protects Your Landscape

When you buy mulch or compost from Hansen’s, you’re not just getting a byproduct of tree work—you’re getting a carefully engineered soil amendment that is clean, healthy, and safe. Properly processed mulch helps suppress weeds, retain soil moisture, and slowly feed the earth, all without introducing new problems to your landscape.

Think of it like pasteurizing milk: it’s about making sure the good stays in and the bad is eliminated. Our real-time temperature monitoring is the “pasteurization” step that guarantees a safer, healthier, and more effective product for your plants.

In Short: Heat Matters

The next time you spread a fresh layer of mulch or topdress your garden beds with compost, you can feel confident that Hansen’s has put in the work behind the scenes to protect your soil—and your peace of mind.

Healthy soil starts with healthy practices. And at Hansen’s Tree Service, we’re proud to bring the science of soil care directly to you.
