Soil Moisture Meter Buyer’s Guide
Are your potted plants dropping leaves like no tomorrow? Are your veggies or fruits failing to produce? Do the flowers in your beds keep shriveling up right after you plant them? Despite the fact that you’ve used high-quality soil and fertilizers and you’ve made sure that your plants are receiving the appropriate amount of sun that their particular species requires, if your flowers, veggies, fruits, succulents, or whatever type of plants you’re trying to grow are failing to thrive, there’s a simple – yet vital – part of care that you may be overlooking: moisture.
It’s no secret that all varieties of plants need water, not only to survive, but to thrive. However, different species have different moisture requirements, and trying to determine how much water your plants need – and making sure that you’re meeting those needs – can seem like a difficult task.
Fortunately, there’s a way that you can assess the moisture content in the soil your plants reside in and ensure that they’re receiving the moisture they need in order to thrive. How? – With a moisture meter!
As the name suggests, a soil moisture meter is a specially designed gardening tool that measures the moisture levels in the soil your plants reside in. These tools are really quite simple; all you need to do is probe the soil moisture meter into the soil around the base of your plants and the device will display the level of moisture content around the root system. Based on the information your moisture meter displays, you’ll instantly know whether it’s time to water or if you should hold off for a couple of days.
In other words, a moisture meter can help you avoid over-saturating the soil and potentially drowning your plants, as well as prevent you from holding off on watering too long and completely drying out your plants. Put simply, with very simply, yet very handy tool, you can promote healthier, happier plants.
It’s no secret that plants need adequate moisture in order to thrive; however, it can be difficult to determine how much moisture is in the soil and when it’s time to water. If you wait too long and the soil becomes too dry, the roots can shrivel up, and if you water too soon, the roots can become waterlogged; either way, your plants could die.
A soil moisture meter takes the guess work out of determining the moisture content in your soil so that you know when it’s time to water; in other words, these handy tools can help to ensure that your plants not only survive, but that they thrive.
As you can see from our list of reviews, there are several different types of soil moisture meters currently available on the market. While all of the models we selected are high-quality, you really only need one.
So, how do you narrow down the options and decide which one will best suit your particular needs? – By taking some key factors into consideration. In this section of our guide, we share the most important factors that you should consider when you’re shopping for a soil moisture meter, as doing so will allow you to determine which model will work the best for you and help you maintain the health of your plants.
The Type of Soil Moisture Meter
As you’re shopping, you’re going to find that there are several types of soil moisture meters, so the first thing you’re going to want to do is consider which type will best suit your needs.
Some models features a bunch of bells and whistles, while others are simplistic and are designed to simply measure the moisture content in your soil. For a basic gardener, you really only need something basic; however, if you’re a commercial farmer or you’re planning on using it for other applications, such as measuring the moisture in a compost pile, a more advanced model may be better suited for your particular needs.
Examples of the different types of moisture meters for soil include:
With an analog meter, batteries aren’t required. These tools are quite simple, yet they’re very effective. The majority of analog moisture meters work via conduction of electricity; the naturally-occurring electrical current that’s found in soil.
The tip of the probes on these models feature at least two types of conductive metal, and if any water is in the soil, the electrical current that naturally travels through the soil will be transmitted to the probe.
That’s because water naturally conducts energy. The more water in the soil, the higher the electrical charge the meter produces will be, and the lower the water level, the lower the electrical charge. Typically, these soil moisture readers are highly accurate.
Digital meters are more advanced in design and usually, they feature more features than a standard analog meter. Usually, the probe part of the meter doesn’t corrode and rely on batteries in order to deliver power to the screen on the meter.
Additionally, they often deliver a small electromagnetic pulse that is able to detect moisture. The probes are usually situated on cables instead of being secured directly on the tool itself.
There are basic and hybrid digital soil moisture meters. Some options can be charge using a USB cable, and these models may also be able to display date related to moisture levels to software, such as on your computer, smartphone, or tablet.
The wicking soil moisture meter is the earliest style of moisture readers, but they’re highly accurate and they’re very popular for use with houseplants. This kind of meter absorbs moisture from the part that is placed in the soil and the moisture is then “wicked” (hence the name) upward to a piece of material that changes color if the soil contains moisture. The less color displayed on the fabric, the dryer the soil will be.
Wicking moisture meters are designed to remain in the soil, which is why they’re intended for house plants. With this type of meter in place, you can quickly and easily see when it’s time to water your indoor potted plants.
It should be noted that this style isn’t intended for use outside, as it doesn’t work well in outdoor climates or when exposed to direct sunlight.
This style of soil moisture meter is becoming increasingly popular and will give you the biggest bang for your buck. They aren’t used solely to determine a plant’s hydration needs, either; they may also feature a sensor that reacts to light and can measure sunlight levels, as well as a pH meter that can measure the pH acidity level of your soil.
However, if you’re using this type of meter to measure pH levels, it should be noted that they aren’t always accurate, so you may still need to conduct additional testing; however, the device can at least give you an idea that there’s an issue.
Once you decide what type of soil moisture meter will work best for your specific needs, you should then consider the overall construction of the tool. Since you’re going to be using it on a regular basis and will be pushing it into and pulling it out of soil, it will be exposed to relatively harsh conditions and you want to be sure that it can withstand the general wear and tear. The best soil moisture meters are constructed of high-grade and durable, yet lightweight, corrosion-free metal, such as aluminum. If there are any plastic components, those should also be highly durable to ensure that they don’t break.
It’s also important to consider the display that your soil moisture reader uses. The display is what you will be using to see how much moisture is in your soil, so you want to be sure that it’s clear and easy to read. Most meters feature a scale that ranges from 1 to 10, with 1 being the driest and 10 being the wettest. Be sure to assess the display before you purchase a meter so you can be sure that you’ll be able to easily read it.
Of course, you also want to be sure that the soil moisture meter you choose provides accurate readings. If it doesn’t, it really isn’t going to do you any good, is it? In order to determine the accuracy of a soil moisture meter, read through customer reviews to see if you can find out what other users have had to say about.
