When to water monstera in winter is a question that comes up for almost every plant parent when the days get shorter and the temperatures drop.
The short, honest answer is that you should water your monstera in winter much less frequently than you do in summer, usually every two to three weeks, but the real key is to check the soil first.
If you’ve been wondering when to water monstera in winter, you already know that these gorgeous tropical plants slow down their growth as the light fades.
That slower growth means they drink less water, so your usual watering schedule from the warmer months will likely lead to overwatering and root rot.
In this post, we’ll walk through the exact signs that tell you when to water monstera in winter, how to adjust your care routine, and the mistakes to avoid so your plant stays healthy until spring.
Let’s dive in.
When to Water Monstera in Winter: The Timing Basics
The best way to figure out when to water monstera in winter is to stop watching the calendar and start watching your plant.
Your monstera doesn’t care what day it is, it only cares about how much moisture is left in its soil.
That said, having a general timeline helps you know what to expect, so you don’t panic.
1. The Two-to-Three Week Rule
As a general guideline, you’ll likely water your monstera every 14 to 21 days during the winter months.
This is a significant shift from the weekly watering you might do in summer.
The reduced daylight and cooler indoor temperatures slow down the photosynthesis process, meaning your plant simply doesn’t need as much water to stay happy.
So, if you’ve been watering weekly, it’s time to stretch those intervals out.
2. Light Conditions Play a Huge Role
The amount of natural light your monstera receives in winter heavily influences when to water monstera in winter.
If your plant sits by a bright south-facing window, it might still dry out fairly quickly and could need watering closer to every two weeks.
But if your monstera is in a darker corner, it will stay moist for much longer, sometimes even up to four weeks.
You have to adjust based on your specific home environment.
3. Indoor Humidity and Heating Effects
Winter heating can dry out the air in your home, which actually pulls moisture away from the soil faster than you might think.
If you run a wood stove or forced-air heating, your monstera’s soil could dry out quicker than in a home with a humidifier running.
Check the top inch of soil more often to see whether your heating habits are making the soil dry faster.
How to Tell It’s Time to Water Your Monstera in Winter
Since timing varies so much, it’s better to rely on physical cues from the plant itself to know when to water monstera in winter.
Here are the most reliable signs that your monstera is thirsty.
1. The Finger Test on the Top Inch of Soil
Stick your finger about one to two inches into the soil.
If the soil feels completely dry at that depth, it’s time to water your monstera.
If it feels even slightly damp, wait a few more days and check again.
This simple test is the most accurate way to know when to water monstera in winter because it removes all guesswork.
2. Drooping or Curling Leaves
Monstera leaves are usually large, flat, and perky.
When the plant is thirsty, the leaves might start to droop slightly or the edges may curl inward a bit.
This is a last-resort sign that the plant is really dry, so if you catch it early, you’ll know it’s definitely time to water your monstera.
3. The Pot Feels Noticeably Lighter
Pick up your monstera pot after watering and get a feel for its weight.
Then pick it up again after two weeks.
When the soil is dry, the pot will feel significantly lighter.
This trick takes a bit of practice, but once you get the hang of it, you’ll know exactly when to water monstera in winter just by lifting the pot.
4. A Moisture Meter for Precision
If you want zero guesswork, grab a cheap moisture meter from any garden store.
Insert it into the soil and check the reading.
When the meter shows the soil is dry in the root zone, that’s your clear signal for when to water monstera in winter.
Best Practices for Watering Your Monstera in Winter
Knowing when to water monstera in winter is half the battle, but how you water matters just as much.
The following tips will keep your monstera thriving even in the coldest months.
1. Always Water Deeply and Thoroughly
When you finally decide it’s time to water your monstera, don’t just give it a tiny sip.
Water it slowly and deeply until water runs out of the drainage holes at the bottom of the pot.
This ensures the entire root ball gets moisture, not just the top layer.
Then, let the pot drain completely before placing it back in its saucer.
2. Use Room Temperature Water
Cold tap water can shock the roots of your tropical monstera, especially in winter.
Let the water sit out for 24 hours to reach room temperature and allow any chlorine to evaporate.
This small step makes a big difference in preventing stress.
3. Skip the Fertilizer
When you water your monstera in winter, resist the urge to add liquid fertilizer.
Your plant isn’t actively growing during this time, so extra nutrients will just sit in the soil and potentially burn the roots.
Wait until early spring to resume feeding.
4. Consider the Potting Mix
A well-draining potting mix is essential for monstera care year-round.
If your soil stays soggy for more than a week after watering, the mix might be too heavy.
Consider adding perlite or orchid bark to improve aeration and drainage.
Common Winter Watering Mistakes to Avoid
Even experienced plant parents slip up when it comes to deciding when to water monstera in winter.
Here are the most common pitfalls and how to steer clear of them.
1. Overwatering Out of Habit
The biggest mistake is sticking to your summer schedule.
If you water monstera in winter as often as you did in July, you’re almost guaranteed to drown the roots.
Always check the soil first before pouring any water.
2. Watering on a Fixed Day
Don’t mark “Water Monstera” on your calendar for every Monday.
Your plant’s needs change week to week based on temperature, humidity, and light.
Instead, let the condition of the soil dictate when to water monstera in winter.
3. Ignoring Root Rot Symptoms
If the leaves turn yellow and mushy, and the soil smells sour, you’ve likely been watering too much.
Root rot can happen fast in winter because the soil stays wet longer.
If you suspect it, remove the plant from the pot, trim away mushy roots, and repot in fresh dry soil.
So, When to Water Monstera in Winter?
When to water monstera in winter comes down to a simple principle: only water when the top two inches of soil are completely dry.
That usually translates to every two to three weeks, but it varies with your home’s light and humidity.
Watch your plant for drooping leaves, check the pot weight, and use your finger or a moisture meter to guide you.
Water deeply with room temperature water, always let the pot drain fully, and skip the fertilizer until spring.
By tuning into your monstera’s needs instead of a rigid schedule, you’ll keep it happy and hydrated through even the darkest winter months.
Your monstera doesn’t need much from you in winter, just a little patience and a lot of observation.
Once spring arrives and the light returns, you can go back to your more frequent watering routine.
But for now, when in doubt, wait a few more days.
Your monstera will thank you for it.
