We spent several hours searching the internet for best moisture meter for plants, reading reviews, and drawing on our own personal experiences to compile our list of the top 13 best moisture meter for plants now available on the market.


Overview

Providing the right amount of water to your plants is essential to their health, but it can be difficult to do so. It's easy for beginners to make mistakes like overwatering or underwatering their plants, but even seasoned gardeners can make mistakes. Gardeners can use soil moisture meters to measure the amount of moisture in the soil. To see if they live up to the hype, we put the most popular ones to the test to see if they are as accurate as they claim to be.

Different types of soil moisture meters were tested in a variety of growing mediums to see how well they could detect moisture differences. We ran the meters through their paces on bone-dry soil before adding water to see how well they responded to the new moisture.

Moisture levels can also be helpful in determining if the soil is draining properly or if it is retaining too much water. If the soil is dry after a rainstorm, for example, it may be draining excessively. This can help gardeners avoid some of the guesswork by giving them an accurate reading of soil moisture levels.

Here, we've put together a list of the best soil moisture meters currently available, so keep reading to learn more about what to look for when purchasing one.

Electronic vs. Manual

Analog and digital displays are both available on moisture meters. Analog displays transmit data manually, whereas digital displays do so via electronics. Electronics, by their very nature, increases the risk of malfunction. As a result, in harsh, outdoor environments, we almost always opt for a manual tool. There are fewer components in analog moisture meters that can be damaged by the weather or other environmental factors, making them more resistant to wear and tear.

As long as you don't plan on monitoring your plant's well-being via a computer, this rule doesn't apply. It's possible to get useful information about your plant's long-term water and sunlight consumption from smart moisture meters. The more you know about your growing conditions, the better prepared you'll be to plant a garden in a new location or in an unfamiliar part of your yard or home.

Scope Length

From a few inches to more than two feet long, moisture meter scopes are available. Your plants, growing conditions, and budget all play a role in determining how big you need your greenhouse to be.

If you're trying to accurately measure the moisture levels of large plants, you'll need a longer probe than you would for smaller plants. If you're growing plants in the ground or in large containers, a longer probe will give you a better sense of the overall moisture levels in your soil. Investing in a long-probe moisture meter is an investment that is best left to those who really need it. If not, allocate some of your resources toward purchasing a second moisture meter with a medium or long probe.

Extra Features

More than just soil moisture can be measured by some moisture meters. They can also monitor fertilization, pH levels, or sunlight. Plants thrive in an environment that includes all of these factors. Keeping track of things like which plants are getting enough sunlight and whether or not your soil's pH needs to be adjusted with additives can be extremely beneficial to your plants' health. If you want a moisture meter with these additional features, you'll have to pay a little more money. An investment that pays off!

Indoor vs. Outdoor Use

When it comes to growing any type of plant, a soil moisture sensor is an essential piece of equipment. A few features to keep in mind when purchasing soil moisture meters for indoor and outdoor use. When choosing a moisture meter for an indoor or outdoor garden, the length of the probe, which can range from 6 to 15 inches, is an important consideration.

Most houseplants are smaller and have looser soil than their outdoor counterparts. It may be possible to use a moisture meter with a short probe for indoor potted plants, which are typically shallow. When used indoors, shorter probes are more convenient to store and less likely to break.

The ability to withstand the elements is an important consideration for outdoor plants. A probe at least 14 inch thick or a stainless steel housing instead of plastic should be more resistant to bending, so look for a strong meter. The longer the probe, the better it is for outdoor use, such as checking a pile of compost. The diameter of the probes on a compost moisture meter is typically about 5/16 of an inch.

Analog vs. Digital

Analog and digital soil moisture meters are both available. The average gardener can save money by using an analog meter. The moisture readings on these meters are usually displayed on a 1 to 10 scale, with the numbers colored to make it easier to see. There are no batteries required for analog meters, so they can be used right out of the box.

 

They can include many useful features, but they also come at an expensive price. Compared to a simple analog meter, these can be more accurate, easier to read, and have remote or smart connective capabilities, all at a higher cost than the analog model. Batteries or USB charging are required for digital soil moisture meters.

Clear and easy-to-read displays are helpful regardless of the type of moisture meter. The top of some meters have an angled display to make it easier to see the readings while they are buried.

Soil Type and Texture

The type and texture of the soil can have an impact on the soil moisture meter that is best suited for your needs. With heavier clay soils, you'll want to use an instrument with an extremely durable probe in order to get accurate readings. A meter's probe can bend or dent in hard soil even if it's made out of aluminum or steel. These soils require a probe that is at least 14 inch thick.

When it comes to outdoor plants, it's more important to have a soil moisture meter that can handle looser potting soil. Regardless of the type of meter, it's best not to use excessive force when inserting it into the ground. Any soil type or texture that exhibits high resistance should be avoided at all costs.

A soil salinity test may also be useful if your plants aren't thriving because high levels of sodium in the soil can cause inaccurate readings. In salt-affected soils, a soil moisture meter may show a higher moisture content than it actually is. It can be helpful in these situations to physically examine and test the soil.

Accuracy

A moisture meter's accuracy is obviously important. Consider using a digital moisture meter to get the most accurate reading. For example, soil moisture levels can be measured to the decimal point or percentage in some digital meters, making them more accurate than analog meters.

Accuracy can also be improved by features such as calibration. Adjusting the calibration for different conditions, such as gardening or composting, humidity levels or the specific moisture requirements of specific plants is possible with a meter that is user-calibrated.

Consider the appropriate length of the probe for the intended application. Moisture meters for plants and compost are very different in length. Because moisture sensors are typically located at the end of the probe rather than throughout the entire length of the meter, the correct length is critical for an accurate reading." The length of the probe must be sufficient to reach the area to be analyzed. From a few inches to up to 24 inches, probes can be made.

Ease of Use

It's not difficult to use the majority of soil moisture meters. It's so simple, isn't it? Put the meter in the ground and you're done. That's not going to happen. You must be careful not to break the probes when putting them in the ground. The Gain Express, for example, has a longer lifespan and is therefore simpler to operate. If the soil is dry or rocky, buyers should look for more durable meters. In contrast, the iPower Soil pH Meter tells you that the ground must be wet in order for it to work properly.

A soil moisture meter's ability to read and switch between different readings is critical if you're looking at a multifunction meter. Users will appreciate models with a switch because they can choose which reading they want to see.

Price

As with most things, you get what you pay for when it comes to soil moisture meters. There are meters that can do more than just measure soil moisture, but if you don't want to take out a second loan, you can still find meters that aren't prohibitively expensive. Be aware that you may end up with more headaches in the form of inaccurate readings and broken meters by purchasing a less expensive moisture meter.

FAQS

How do you read a plant moisture meter?

Usually from 1 to 10, analog moisture meters are displayed on a scale. The amount of moisture in the soil is indicated by the movement of a needle. Moisture meters with a numerical rating are common in digital devices. Depending on the digital moisture meter, it may be displayed as a percentage or as a number from 1 to 10.

Color-coded dials on plant moisture meters indicate whether the soil is too wet (red), too dry (green), or somewhere in between (blue). Plant moisture meters are much easier to read with this method.

How accurate are the readings on plant moisture meters?

Smaller intervals on a moisture meter scale are more accurate than larger intervals. Using longer probes, especially in areas with deep-rooted plants or deep soil, can also improve accuracy. A double-probe moisture meter is generally more accurate, especially if it is used to measure a variety of different variables. In order to get the most accurate reading, it is best to use separate sensors for pH and moisture.

Calibration options are available on some moisture meters, which allow you to set the scale to a specific neutral reading that the meter will then use as a basis for all future readings. It is possible to set a smart moisture meter to a specific plant and get readings based on the ideal growing conditions for that species.

What should your soil moisture be?

Depending on the type of plant being grown, the ideal soil moisture level will be different. There are some plants that can thrive with very little water (as low as 1 or 2 on a 10-point scale), while there are others that prefer very wet soil (8 or higher).

Can I leave my moisture meter in the soil?

Most meters on the market should not be left in the ground, depending on the model. Water meters can withstand some wear and tear but leaving them in the ground can lead to corrosion and degradation. Clean and store the moisture meter after each use unless otherwise stated. If you want it to stay in place in your garden, look for a type that is specifically made for that purpose.

Conclusion

Nielsen points out that soil moisture meters aren't always accurate, but it's never a bad idea to have more information about your watering schedule! It's a good idea to use this if you're trying to keep your garden or houseplants well-watered. The only thing that compares to the human touch is your own hands.
