How to Water a Monstera: Complete Watering Guide

Wondering how often to water your monstera? The answer isn't as simple as "once a week"—your monstera's watering needs change with seasons, pot size, humidity, and light levels. Getting the watering schedule right is the difference between a thriving plant with gorgeous fenestrated leaves and one struggling with yellow leaves or root rot.

How Often to Water Your Monstera

The golden rule for watering your monstera 🌿Monstera deliciosa (mon-STER-ah de-lis-ee-OH-sah) is water when the top 1-2 inches (3-5 cm) of soil feels dry to the touch. This typically translates to:

Growing Season (Spring-Summer):

• Every 7-10 days for most indoor conditions

• Every 5-7 days in very bright, warm locations

• Every 10-14 days in lower light or cooler rooms

Dormant Season (Fall-Winter):

• Every 2-3 weeks for most indoor conditions

• Every 3-4 weeks in cool, low-light conditions

• Monthly for plants near heating vents or in dry air

The key is checking soil moisture rather than following a rigid schedule. Your monstera's needs vary based on several factors:

Factors Affecting Watering Frequency:

• Pot size: Larger pots hold moisture longer; smaller pots dry faster

• Soil type: Well-draining mixes dry quicker than heavy potting soil

• Light levels: Brighter light increases water consumption through transpiration

• Temperature: Warmer conditions accelerate soil drying

• Humidity: Lower humidity increases plant water needs

• Season: Active growth periods require more frequent watering

• Plant size: Larger plants with more leaves use water faster

I learned this the hard way when I first got my monstera—I stuck to a weekly schedule and nearly killed it with root rot during winter when it needed water every three weeks, not seven days.

Signs Your Monstera Needs Water

Learning to read your monstera's signals is more reliable than any schedule. Here's what to watch for:

Visual Signs It's Time to Water:

• Top 1-2 inches (3-5 cm) of soil feels dry when you stick your finger down

• Potting mix pulls away from pot edges slightly

• Leaves begin to droop subtly (not dramatically—that's underwatering damage)

• Older bottom leaves start looking slightly less perky

• Soil feels light when you lift the pot (compared to after watering)

• Moisture meter reads 2-3 on a 10-point scale

Early Warning Signs (Act Soon):

• Newest leaves appear slightly less glossy than usual

• Leaf edges feel less firm to touch

• Aerial roots look slightly shriveled at tips

• Growth slows noticeably during active season

Never Wait for These Emergency Signs:

• Leaves curling inward (plant is already stressed)

• Dramatic drooping throughout the plant

• Lower leaves yellowing rapidly

• Soil shrinking significantly from pot walls

• Pot feels very light compared to normal weight

The best approach? Check your monstera every 3-4 days by inserting your finger into the soil. You'll quickly learn what "ready for watering" feels like for your specific plant and conditions.

Proper Watering Technique

How you water matters as much as when you water. Follow this step-by-step process:

Step 1: Pre-Water Check

• Remove decorative cache pot if using one

• Check that drainage holes aren't blocked

• Empty any standing water from saucer

• Prepare lukewarm water (room temperature or slightly warm)

Step 2: Deep Watering Method

• Water slowly and evenly across soil surface

• Continue until water runs freely from drainage holes

• Wait 2-3 minutes, then water again if soil absorbed quickly

• Stop when water flows consistently from bottom

Step 3: Post-Watering Care

• Let excess water drain for 15-30 minutes

• Empty saucer completely—never let plant sit in standing water

• Replace in decorative pot if using one

• Note the date for future reference

Volume Guidelines: -
Small plants (under 2 feet/60 cm): 1-2 cups water typically sufficient -
Medium plants (2-4 feet/60-120 cm): 2-4 cups depending on pot size -
Large plants (4+ feet/120+ cm): 4-8 cups or more until drainage occurs

The amount varies significantly based on pot size and soil type. Focus on watering until drainage occurs rather than measuring specific volumes.

Bottom-Up Watering Method (Alternative): Some plant parents prefer bottom watering for monsteras:

• Place pot in tray filled with 1-2 inches (3-5 cm) of water

• Let plant soak for 30-60 minutes until top soil feels moist

• Remove from water tray and let excess drain

• Empty tray completely

Bottom watering works well for preventing fungal issues and ensures even soil saturation, though it takes longer than top watering.

Water Quality and Temperature

Your monstera cares about water quality more than you might think. Here's what to use:

Best Water Choices:

• Filtered water: Removes chlorine, fluoride, and heavy minerals

• Distilled water: Pure but lacks beneficial minerals (okay occasionally)

• Rainwater: Ideal if collected safely and stored properly

• Tap water left out 24+ hours: Allows chlorine to evaporate naturally

Water to Avoid:

• Fresh tap water: Chlorine and fluoride can damage roots over time

• Softened water: High sodium content harms tropical plants

• Very hard water: Mineral buildup affects soil pH and nutrient uptake

• Cold water: Can shock tropical plant roots

Temperature Matters: Use lukewarm water (65-75°F/18-24°C) to avoid shocking the root system. Cold water can slow nutrient uptake and stress tropical plants adapted to warm soil temperatures.

If your tap water is heavily chlorinated or fluorinated, invest in a simple water filter. Your monstera will show improved growth and fewer brown leaf tips with better water quality.

Seasonal Watering Adjustments

Your monstera's water needs change dramatically with seasons. Here's how to adjust:

Spring (March-May): Increasing Water Needs

• Transition from winter schedule gradually

• Watch for new growth—increase watering frequency as leaves emerge

• Begin weekly soil checks instead of bi-weekly

• Resume monthly fertilizing which increases water uptake

Summer (June-August): Peak Water Usage

• Most frequent watering period of the year

• Check soil every 3-4 days in hot weather

• Increase humidity to reduce water stress

• Monitor for faster soil drying near air conditioning vents

Fall (September-November): Gradual Reduction

• Slowly decrease watering frequency as temperatures drop

• Stop fertilizing by October to prepare for dormancy

• Reduce from weekly to bi-weekly checks

• Watch for slower soil drying as light levels decrease

Winter (December-February): Minimal Watering

• Least frequent watering of the year

• Check soil every 10-14 days but expect less frequent watering

• Be especially careful not to overwater—root rot risk is highest

• Plants near heating systems may need slightly more frequent water

Monthly Watering Calendar:

Remember, these are guidelines—always let soil moisture be your primary indicator.

Humidity vs Watering

Many new monstera owners confuse humidity needs with watering needs. Understanding the difference prevents overwatering:

Humidity Requirements: -
Ideal range: 60-70% relative humidity -
Minimum tolerated: 40-50% -
Signs of low humidity: Brown leaf tips, curling edges, slow growth

How to Increase Humidity (NOT More Watering):

• Humidifier: Most effective method, maintains consistent 60-70%

• Pebble tray: Fill saucer with pebbles and water, place pot on top

• Plant grouping: Cluster plants together to create microclimate

• Room placement: Avoid heating vents, place in naturally humid areas like bathrooms

What NOT to Do:

• Don't mist leaves daily: Can promote fungal issues and doesn't significantly increase humidity

• Don't water more frequently: Soil moisture and air humidity are separate needs

• Don't use wet towels around plants: Creates stagnant moisture, not healthy humidity

If you're struggling with low humidity in your home, investing in a quality humidifier makes a bigger difference than adjusting your watering schedule. Check out our Best Humidifiers for Monstera and Tropical Plants for tested recommendations.

Common Watering Mistakes

Avoid these mistakes I've seen (and made) countless times:

Mistake #1: Watering on a Fixed Schedule -
Wrong approach: "I water every Sunday" -
Right approach: "I check soil moisture every few days and water when top 2 inches are dry" -
Why it fails: Plants' needs change with seasons, weather, growth phases

Mistake #2: Not Watering Thoroughly -
Wrong approach: Giving small amounts of water frequently -
Right approach: Deep watering until drainage occurs, then waiting for soil to partially dry -
Why it fails: Shallow watering encourages shallow root growth and doesn't reach bottom roots

Mistake #3: Leaving Water in Saucers -
Wrong approach: Letting plants sit in standing water "for extra moisture" -
Right approach: Empty saucers completely 30 minutes after watering -
Why it fails: Standing water causes root rot, especially in cooler months

Mistake #4: Using Cold Water -
Wrong approach: Watering straight from cold tap -
Right approach: Use room temperature or slightly warm water -
Why it fails: Cold water shocks tropical plant roots, reducing nutrient uptake

Mistake #5: Confusing Humidity with Soil Moisture -
Wrong approach: Watering more frequently when humidity is low -
Right approach: Address humidity separately with humidifier or pebble tray -
Why it fails: Creates overwatered soil while humidity problem persists

Mistake #6: Not Adjusting for Seasons -
Wrong approach: Same watering frequency year-round -
Right approach: Reduce frequency significantly in winter months -
Why it fails: Winter overwatering is the #1 cause of monstera death

Troubleshooting Watering Issues

Problem: Yellow Leaves After Watering

Possible Causes:

• Overwatering (most common)

• Poor drainage

• Wrong water type (chlorinated, softened)

• Cold water shock

Solutions:

• Check soil drainage—should dry in 7-10 days maximum

• Ensure pot has adequate drainage holes

• Switch to filtered or dechlorinated water

• Reduce watering frequency immediately

Problem: Leaves Drooping Despite Moist Soil

Possible Causes:

• Root rot from overwatering

• Compacted soil preventing drainage

• Pot too large for plant size

Solutions:

• Remove plant and inspect roots—trim any brown/mushy areas

• Repot in fresh, well-draining soil mix

• Choose pot only 2-3 inches (5-7 cm) larger than root ball

Problem: Brown Crispy Leaf Tips

Possible Causes:

• Low humidity (not watering issue)

• Chlorinated/fluorinated tap water

• Fertilizer burn from overfeeding

Solutions:

• Increase humidity with humidifier

• Switch to filtered water or let tap water sit 24+ hours

• Flush soil with plain water to remove salt buildup

Problem: Soil Dries Out Too Quickly (Daily)

Possible Causes:

• Pot too small for plant size

• Very chunky, fast-draining soil mix

• Extremely bright/hot location

• Low humidity environment

Solutions:

• Repot into next size up container

• Add some peat moss or coco coir to soil mix for moisture retention

• Move to slightly less bright location

• Increase ambient humidity

Problem: Soil Stays Wet for Weeks

Possible Causes:

• Poor drainage from blocked holes or no holes

• Soil too heavy/dense (regular potting soil instead of aroid mix)

• Pot too large for current root system

• Cool, low-light location slowing transpiration

Solutions:

• Ensure multiple drainage holes are clear

• Repot in chunky, well-draining aroid soil mix

• Move to smaller pot if current one is oversized

• Relocate to brighter, warmer location if possible

When troubleshooting watering issues, always start by examining the roots. Healthy monstera roots should be white to cream colored, firm, and numerous. Brown, mushy, or foul-smelling roots indicate watering problems that need immediate attention.
