Whether you’re a new or seasoned plant parent, trying to keep up with the watering schedule of all the plants in your home can be a headache.

So, in this post, we’ll cover the 5 best soil moisture meters for houseplants so you can stop guessing if your plant needs water.

Start knowing exactly how much water to give your plants, keeping them alive longer.

What Is A Soil Moisture Meter?

Before we dive into our top soil moisture meters for indoor plants, it’s important to understand what is a soil moisture meter.

A soil moisture meter is a tool used to measure the moisture content in the soil of your plants.

You can use a soil moisture meter to determine if your plants need water or if they have been given too much water.

Moisture soil meters are excellent for testing the moisture level of your plant’s soil right down to the root area where you can’t always reach by hand.

5 Benefits Of Using A Soil Moisture Meter For Indoor Plants

  • Know when to water your plants
  • Measure moisture content at the root level
  • Won’t damage plant’s roots
  • Makes caring for indoor plants easier
  • Saves money in the long run (not replacing overwatered plants)

Know when to water your plants: Soil moisture meters take the guesswork out of knowing when to water your plants.

Measure moisture content at the root level: It’s important to know how much water is actually getting to the root level.

Some soil may be retaining too much water, while other soil types may be preventing water from soaking all the way through.

A soil moisture meter will help you determine if the water is getting to the bottom root level or if too much is staying at the top.

This will also help you know if your soil needs adjusted.

Won’t damage the plant’s roots: Many plants have fragile roots.

You want to do your best not to damage your plant’s roots which can happen when you poke and prod your finger around trying to determine if the soil under the top layer is wet.

If you hear a ripping sound when poking around, you are most likely breaking that plant’s roots.

If too many of the roots get damaged, especially on a plant that hasn’t matured yet, your plant may die.

A soil moisture meter has a thin probe.

Once it’s inserted into the soil we recommend leaving it there, allowing the roots to grow around it.

Makes caring for indoor plants easier: As mentioned earlier, one of the most common causes of death in houseplants is over-watering or under-watering.

You may be tempted to water your plants if the top feels dry but this could end up having an adverse effect if the bottom of the pot is still heavily soaked.

By placing a moisture soil meter in your plant’s soil, you’ll be able to better monitor the soil content from day to day making it easier to care for your plants, knowing when they need to be watered.

Saves money in the long run: Plants can be expensive and it’s super disappointing when your new plant dies within weeks of bringing it home.

Knowing when and how much water to give your plants will help keep your plants alive longer, saving you from spending money to constantly replace your plants.

Purchasing a soil moisture meter for plants has made caring for plants much easier, especially for new plant owners.
