    Know what's happening below the surface! Soil probes are excellent tools to understand the condition of your soil and when it is time to water. Overwatering is the most common reason plants perish, especially in planters without drainage holes. The soil probe not only allows you to check the soil moisture at the root zone level, but can also act as a tool to aerate the roots -- the best way to save an overwatered plant before it is too late. 

    For more information, see our How To Use A Soil Probe guide. 
    • Anti-microbial brass prevents transmission of pests and pathogens
    • Aerates the soil so plants can breathe
    • Designed by professional horticulturists
    • Manufactured in China


    Brass will tarnish. To keep the soil probe looking its brightest, rub down with brass polish periodically.

Great idea with some small flaws

It's nearly impossible to find decent soil probes for houseplants so I was excited to find this beautiful piece. It looks amazing and does it's job well. I only wish the notches on the probe were slightly larger/smoother. As they are now it's difficult to dislodge the soil samples from the probe. They're cut very precisely and are pretty sharp. Be careful!

Before buying the monitor brass soil probe, I was the type to always over-water my plants. I felt like if I wasn’t watering them, then I wasn’t doing anything for them. With the brass probe I am able to test the soil as often as I want - so that while I am not over-watering the plants, I still feel like I get to check on them. Since I began using the probe, I find that I am checking the soil less because I have grown to appreciate the time in between watering. It is a great tool for beginners like myself!

Awesome tool

Great tool for checking soil dryness
