Monstera Watering 101: A Simple Guide for Healthy, Happy Plants

Proper monstera watering involves letting the top 2 to 3 inches of soil dry completely between waterings, typically every 1 to 2 weeks for most varieties. Adjust frequency based on light, temperature, and pot drainage to avoid root rot, and always empty excess water from saucers to prevent soggy soil.

How Often to Water Monstera Plants

Water most monstera varieties every 1 to 2 weeks, adjusting based on light, temperature, and pot drainage. Let the top 2 to 3 inches of soil dry out completely between waterings to prevent root rot. Misting is not a replacement for deep watering, as monstera roots absorb most moisture from soil.

Watering frequency adjustments by season

• Spring and summer: When growth is active, you may need to water every 7 to 10 days, especially if your plant is in bright indirect light.
• Fall and winter: Growth slows significantly, so reduce frequency to every 2 to 3 weeks, as cooler temperatures and lower light slow soil evaporation.
• Avoid following a rigid schedule without testing soil first, as conditions vary widely between homes.

How to test soil dryness before watering

• Stick your index finger 2 to 3 inches into the soil. If the soil feels completely dry at that depth, it is time to water. If any moisture remains, wait 2 to 3 days and test again.
• Lift the pot to gauge weight: A pot with dry soil will feel significantly lighter than one that has been recently watered.
• For large potted plants where finger testing is difficult, use a cheap moisture meter to get an accurate reading of moisture levels deeper in the root ball.

Monstera Deliciosa Watering Specifics

Monstera deliciosa requires slightly less frequent watering than smaller monstera cultivars, typically every 10 to 14 days in indirect medium light. Their large root systems are prone to rot if left sitting in standing water, so always empty excess water from saucers 30 minutes after watering. Consistent monstera deliciosa watering that avoids soggy soil will support the plant’s large, iconic split leaves and steady growth.

Signs your monstera deliciosa needs water

• The top 2 to 3 inches of soil are completely dry, even in the root zone around the plant’s central stem.
• The pot feels noticeably lighter than it did a week prior.
• Leaves curl slightly inward at the edges, or the entire plant looks droopy despite consistent light conditions.
• Soil pulls away from the inner edges of the pot, indicating it has dried out completely.

How much water to give a mature monstera deliciosa

For a mature monstera deliciosa in a 10 to 12 inch pot, water until you see excess water drain out the bottom of the pot, usually about 2 to 3 cups of water per watering. For larger plants in 14 to 16 inch pots, you may need 4 to 6 cups of water to fully saturate the root ball. Never add small, frequent sips of water, as this can lead to shallow root growth and dry soil deeper in the pot.

Can You Use Tap Water on Monstera?

You can use tap water on monstera if it has low chlorine and mineral content, but avoid heavily chlorinated or softened water, which can cause brown leaf tips. If tap water is high in minerals, let it sit out for 24 hours before use, or use filtered or rainwater for best results. Most municipal tap water is safe for use, but monitor your plant for signs of stress after switching to a new water source.

Signs your water is harming your monstera

• Brown, crispy tips on otherwise healthy green leaves, with no signs of underwatering or pest damage.
• White, crusty mineral deposits on the top of the soil or around the edges of the pot.
• Stunted new growth despite consistent light, temperature, and proper monstera watering practices.
• If you notice these signs, switch to filtered or rainwater for 1 to 2 months to see if the issue resolves.

Alternatives to tap water for sensitive plants

• Rainwater, collected in a clean barrel, is ideal as it is naturally low in minerals and chlorine.
• Filtered water, from a standard household carbon filter, removes most chlorine and excess minerals that can harm monstera leaves.
• Distilled water is also safe, though it lacks small amounts of beneficial minerals that are present in tap or rainwater.
• If you use tap water, avoid water that has been run through a home water softener, as it contains high levels of sodium that can damage roots over time.

How to Tell If Your Monstera Needs Water

Clear signs a monstera needs water include dry top 2 to 3 inches of soil, a lightweight pot, drooping or curling leaves, and soil that pulls away from the edges of the pot. Yellow or mushy leaves are signs of overwatering, not underwatering, so always test soil before adding more water. If you are unsure about your plant’s moisture needs, log your observations in a care tracker to spot patterns over time.

Common underwatering vs overwatering mistakes

• Underwatering signs: Crispy brown leaf edges, curling leaves, slow new growth, and soil that pulls away from pot edges. Fix by giving the plant a deep, thorough watering, and adjust your schedule to test soil more frequently.
• Overwatering signs: Yellow mushy leaves, soft brown stems, a foul smell from the soil, and visible root rot. Fix by letting the soil dry completely, and repot into fresh, well-draining soil if root rot has set in. Overwatering is the most common cause of death for indoor monstera plants.
• If you see small flying pests around your plant, you may have fungus gnats, which thrive in soggy soil. Learn how to identify common houseplant pests to address the issue early.

How to use the Sproutly app to track watering reminders

The Sproutly app lets you log your plant’s specific variety, light conditions, and pot size to generate customized watering reminders tailored to your home environment. You can also upload photos of your plant to track growth and spot early signs of overwatering or underwatering before they cause permanent damage.

Watering Tips to Avoid Common Monstera Problems

Consistent, deep watering that fully saturates the root ball prevents most common monstera issues like yellow leaves, root rot, and crispy leaf edges. Always use a pot with drainage holes, and never let your monstera sit in standing water for more than 30 minutes. These simple steps eliminate 90% of the most common care issues new growers face with monstera plants.

How to adjust watering for low light vs bright light conditions

• Bright indirect light: Plants in this condition will need water every 7 to 10 days, as soil dries out faster in higher light. Test soil every 7 days to avoid overwatering during weeks with less sun than usual.
• Low light: Plants in low light may only need water every 2 to 3 weeks, as photosynthesis slows and the plant uses less moisture. Avoid placing monstera in direct full sun, as this can scorch leaves and cause soil to dry out too quickly between waterings.

Watering best practices for potted vs staked monstera

• Potted, unstaked monstera: These plants have shallower root systems, so water evenly across the top of the soil to ensure all roots get moisture. Avoid pouring water directly on the central stem to prevent stem rot.
• Staked monstera: As monstera grow up a moss pole, they develop aerial roots that absorb small amounts of moisture from the air and the pole. Mist the moss pole once every 1 to 2 weeks to support aerial root growth, but continue to water the soil as normal for the main root system. If you care for other high-humidity houseplants, our Calathea Watering & Repotting: No-Fuss Care Guide for Healthy Patterned Foliage shares similar tips for supporting aerial root growth.
• Monstera are toxic to cats and dogs if ingested, so place them out of reach of pets. If you are looking for non-toxic alternatives, browse our pet-safe houseplant list for options that work for your home.

Frequently Asked Questions

Does monstera deliciosa need more water than other monstera varieties?

No, monstera deliciosa typically needs slightly less frequent watering than smaller monstera cultivars, as its large root system stores more moisture. Always test the top 2 to 3 inches of soil for dryness before watering to avoid overwatering.

How does sunlight affect monstera watering frequency?

Monstera in bright indirect light will need water every 7 to 10 days, while plants in low light may only need water every 2 to 3 weeks. Higher light levels cause soil to dry out faster, so test soil dryness more often during sunny summer months.

Should I adjust my monstera watering routine in winter?

Yes, reduce watering frequency in winter when monstera growth slows. Most monstera only need water every 2 to 3 weeks in cold months, as lower light and cooler temperatures slow soil evaporation and root moisture uptake.
