How Often to Water a Monstera: A Simple Moisture-Meter Setup Guide
ON THIS PAGE
If you've ever stared at your monstera wondering whether it's thirsty or just fine, you're not alone. The honest answer to "how often to water a monstera" isn't a fixed number of days — it depends on your light, pot, and season. This guide shows you how to use a soil moisture meter so you can read what your plant actually needs instead of guessing.
What You'll Need for Your Monstera
Setting up is quick, and you don't need much. Gather the following:
- A Soil Moisture Meter from RootWise Home
- Your monstera in its current pot
- A watering can or jug of room-temperature water
- A small notebook or your phone to jot down readings
For specifications like probe length or display type, check the product page. The moisture meter is the star here — it takes the mystery out of timing by letting you check moisture at the root zone rather than just the surface.
Setting Up Your Moisture Meter for Monstera Watering
- Read the quick reference on your meter so you know which end of the scale means dry and which means moist (on our meter, 1–3 reads dry, 4–7 moist, 8–10 wet).
- Choose a spot in the pot roughly halfway between the stem and the pot's edge, where most of the active roots sit.
- Insert the probe slowly and steadily into the soil until it reaches near the middle of the root zone, being careful not to force it against a root or the pot base.
- Wait a few moments for the reading to settle, then note where the needle or indicator lands.
- Take a reading in two or three different spots around the pot, since soil moisture can vary from one side to another.
- Record your reading along with the date so you can start to see a pattern over the following weeks.
- Water only when the reading tells you the root zone has dried down toward the lower end of the scale, then wipe the probe clean and store it dry.
By repeating this over a couple of weeks, you'll learn your monstera's natural rhythm — which is far more reliable than a calendar reminder. For the same read-the-soil approach across 15 other common houseplants, see our free printable watering cheat sheet.
Common Mistakes and How to Avoid Them
The biggest slip-up is treating a moisture meter like a strict rulebook. It's a helpful reading tool, not a promise, so pair it with your own observation of the plant and pot. Avoid leaving the probe in the soil permanently; insert it, read it, then remove and clean it.
Don't jam the probe deep against the drainage holes or you may hit the pot base and get an odd reading. Take gentle readings from a few spots for a fuller picture. Finally, remember that light and season change how fast soil dries: a monstera in bright, warm conditions will typically dry faster than one in low light or cooler months. Let the meter reflect those shifts rather than watering on autopilot.

DIY Finger Test vs. a Ready-Made Moisture Meter
There's more than one way to check moisture. Here's an honest comparison so you can pick what suits you:
| Approach | Upside | Watch out for |
|---|---|---|
| Finger-in-the-soil test | Free and always available; quick to learn | Only reaches surface layers; hard to judge deep root-zone moisture |
| Lifting the pot to feel weight | No tools needed; good for spotting big changes | Takes practice; tricky with large or heavy monstera pots |
| Wooden skewer or chopstick | Cheap; shows moisture along its length | Can be messy; readings are subjective |
| Ready-made moisture meter | Reads deeper in the root zone; consistent between checks | Needs correct insertion and cleaning; readings are a guide, not a guarantee |
Many plant parents use a mix: a meter for a clear root-zone reading, plus the pot-lift habit as a quick backup.
FAQ
How often to water monstera adansonii?
Monstera adansonii often dries a little faster than larger varieties because of its trailing habit and smaller pot. Rather than a set schedule, check the root zone with your moisture meter and water once it reads toward the dry end of the scale.
How often to water mini monstera?
The mini monstera (Rhaphidophora tetrasperma) is a vigorous climber that can go through water quickly in bright light. Take a meter reading every few days at first to learn its pace, then water when the soil has dried down appropriately.
How often to water monstera?
There's no universal number — it shifts with light, pot size, and season. Use your moisture meter to read the root zone and water when it trends dry, rather than counting days on a calendar.
How often to water monstera deliciosa?
Deliciosa follows the same factors: warm, bright spots dry faster than cool, dim ones. Check with your meter and water once the reading moves toward dry, adjusting through the seasons.
How often to water monstera plant?
The soil itself gives the best answer. Insert your moisture meter into the root zone, and let a dry reading — not a fixed schedule — be your cue to water again.
