When to Use a Plant Moisture Meter

So why would a plant moisture meter help you care for your plants properly? The thing is, some plants really suffer from overwatering. A way of gauging the dampness of the soil accurately just takes the guesswork away.   

A moisture meter is like a soil probe for indoor plants that can measure the liquid levels in the pot. That means you can give plants more water only when they need it. No more soggy soil or yucky root rot whatsoever!

If you don’t think your plants are looking their best, then getting hold of the best moisture meter for plants could make all the difference. Prevention is also better than cure. Why guess when to water your precious plants when you could be certain that’s what they need?

Can You Use the Moisture Meter on Any Plant?

Yes! A plant moisture meter can be used on any kind of plant and soil. It only measures the amount of moisture in the soil, and doesn’t harm the plant in any way.

Essentially, I tend to use the moisture meter on plants that are harder to care for and those that need more water than others. Plants that don’t need much water, like cacti and succulents, don’t really need to have their water levels monitored.

A moisture meter is especially useful for plants like Ficus Tineke, which can be prone to root rot when watered too often.

How to Use a Soil Moisture Meter

Using plant water meter is so simple anyone can do it. Simply place the metallic probe into the soil where your plant is growing in, and pull it out when you have a reading. It usually takes a minute or two for a soil moisture meter to get a reading.

After you pull out the probe, remember to wipe off the moisture with a serviette or paper towel to make sure your next reading is accurate. It’s super easy to keep a plant water meter clean. I place my soil moisture meter on my living room plant shelves together with my watering can and spray can.

How to Choose the Best Moisture Meter for Your Plants

This was the first thing I thought about when buying the best plant water meter I could lay my mitts on. Are all moisture meters the same? 

Essentially every device like this will indicate the soil’s level of dampness. The main difference is in how this is displayed. Some meters have a simple ‘swingometer’ with a spectrum that runs from dry through moist to wet. 

Other meters may have a digital display that gives an accurate reading. This may also indicate the soil temperature and pH. Some even tell you about the humidity level and how much sunlight your plant is getting!

Here are some factors to look out for when you’re choosing between the top house plant moisture meters.

What to Look For in the Best Soil Moisture Meter

Analog or digital

So as mentioned above you can pick between a simple analog display or go for a digital one. An electronic one is more sophisticated. This type can measure other factors like ph, humidity, temperature and sunlight levels, and is ideal for indoor gardening.  

An analog one is more straightforward, and may be all you need. This uncomplicated type might be best if you ever want to use it outdoors. It’s less likely to be affected by the elements, which could cause glitches with a digital display. 

An electronic display is going to require battery power to work. Purchasing an analog one normally means no batteries are needed. A digital display is easier to read though. 

Temperature, pH, humidity, light & more

For those fussier plants, it may be worth paying extra for a more sophisticated meter. Some gadgets can also tell you about the temperature and pH of the soil. They might also measure the sunlight and humidity levels. 

Again this takes the guesswork out of houseplant care. So it can be well worth forking out a few extra dollars for! One option I’ve listed can even tell you the total dissolved solids and how much electrical conductivity is present – ideal for science fans and gadget devotees. 

Length

The length of the probe you need will depend on the size of your plants and pots. Don’t forget that they may become a lot bigger as they grow! It’s easy to measure from the top level of soil down to where the roots will be to see how long a probe you’ll need.  The best moisture meter for plants is usually just a few inches long.

Best Moisture Meter for Plants FAQs

Are moisture meters for plants accurate?

A good quality moisture meter should be accurate and you can rely on one to help you judge the moisture level of the soil. It’s a far better guide to whether your plant needs more water than simply looking at it or feeling the top level of soil with your finger. This is because it reaches down to the roots. 

What type of moisture meter is most accurate?

A digital moisture meter will give you the most clear answer. However this type is also more likely to be affected by external factors such as humidity and temperature. The likelihood of those aspects fluctuating increases outdoors or in an environment like a greenhouse.
