A clear temperature check for compost piles

The REOTEMP 20 Inch Compost Thermometer gives backyard compost care a simple read on pile temperature. The long stem reaches into the material, and the analog dial shows where the pile sits during a compost check.

That kind of reading is useful when compost is part of the soil-building routine for raised beds, containers, and garden refreshes.

The dial is made for compost decisions

The dial includes compost activity zones, so the reading is easy to understand during a quick garden walk. A gardener can check the pile, then decide whether the next step is turning, adding moisture, adding material, or waiting.

The thermometer does not manage the pile by itself. It simply makes the pile readable.

The 20 inch stem suits backyard bins

The stainless steel stem is long enough for many backyard piles, bins, and tumblers. It helps the gardener reach toward the center of the compost, where the temperature tells a clearer story than the outer surface.

Wipe the probe after use and store it where the stem will stay protected.

Good match

This thermometer fits gardeners who make compost at home and want a straightforward temperature cue for pile activity.

What to know

Use the reading beside the rest of the pile check: moisture, scent, texture, browns, greens, and how recently the pile was turned.
