Soil Moisture Meters: A Buyer's Guide
A soil moisture meter is a super tool to use for plant health. It provides you with clear and easy-to-understand information about any patch of soil, helping you make the best decisions for your plants.
What Does a Soil Moisture Meter Do?
As the name implies, a soil moisture meter is a device that measures the moisture levels in the soil. It features a long probe with a dial or display at the top. Once the probe connects with the soil, it detects the moisture levels and shows you how wet the soil is on the dial.
Why Should I Use a Soil Moisture Meter?
So, what’s the point of using a soil moisture meter in the first place? Well, the main reason people use these devices is to help with their gardening to ensure they do not over or under-water their plants.
It’s vital to water potted plants around the home and other plants or crops in gardens, yards, and fields.
However, if you put too much water or not enough, the plants will suffer negative effects and may even die.
By using a soil moisture meter, you can easily find out how moist the soil is and then decide whether or not more water is necessary. In other words, these devices take the guesswork out of watering your plants.
How Do I Use a Soil Moisture Meter?
It’s important to note that soil moisture meters are all unique. They all appear similar and usually operate in the same way, but some have their own unique quirks and features, so it’s always best to read the instructions before you begin to find out more about your specific device.
In general, follow these steps to use your soil moisture meter:
- To begin, gently push the probe into the soil and push it right down until most of it is buried. Try another spot if you encounter any resistance, like rocks or hard patches.
- Once the soil moisture meter probe is in position, wait for about 60 seconds (times vary between models) and then check the dial.
- The dial should show a reading for the soil moisture. Most devices have a little gauge with an arrow pointing to the moisture level.
- Once you have a reading, you’ll be able to decide whether or not more water needs to be added to the soil.
Remember that plants have different moisture needs. The likes of cacti and succulents don’t need a lot of water and cope well in relatively dry soil, but other plants need lots of water. So it’s important to research each type of plant and know how much or little water it requires.
