The Complete Guide to Watering Houseplants
Watering seems simple, but it's the most common area where plant parents go wrong. Learn the right techniques and your plants will thrive.
Watering Fundamentals
Check before you water
Never water on a schedule alone. Always check soil moisture first. The top 1-2 inches should be dry for most plants.
Pro tip: Stick your finger in the soil to the second knuckle. If it feels dry, water. If moist, wait.
Water thoroughly
When you water, soak the soil until water drains from the bottom. This ensures roots at all levels get moisture.
Pro tip: Light, frequent watering encourages shallow roots. Deep, less frequent watering builds strong root systems.
Empty saucers
Don't let plants sit in standing water. Empty saucers 30 minutes after watering to prevent root rot.
Pro tip: Use a turkey baster to remove water from hard-to-reach saucers.
Use room temperature water
Cold water can shock roots. Let tap water sit for an hour or use room temperature water.
Pro tip: Bonus: letting water sit allows chlorine to evaporate, which some plants prefer.
Watering Methods
Different methods work better for different plants and situations.
Top Watering
Pour water on the soil surface until it drains from the bottom. The most common method.
Pros
- Easy and quick
- Flushes salt buildup
- Works for all plants
Cons
- Can wet foliage accidentally
- May compact soil over time
Best for: Most houseplants, especially those that tolerate wet leaves
Bottom Watering
Place pot in a dish of water and let soil absorb moisture from below for 30-45 minutes.
Pros
- Avoids wet foliage
- Encourages deeper roots
- Great for sensitive plants
Cons
- Doesn't flush salts
- Takes more time
Best for: African violets, cyclamen, plants prone to crown rot
Self-Watering Pots
Reservoir systems that wick water to roots as needed.
Pros
- Consistent moisture
- Good for frequent travelers
- Reduces watering frequency
Cons
- Not for drought-loving plants
- Initial cost
Best for: Moisture-loving plants, busy plant parents
Soaking
Submerge entire pot in water for 15-30 minutes, let drain completely.
Pros
- Thoroughly hydrates dry soil
- Good for very dry rootballs
Cons
- Can be messy
- Not for regular use
Best for: Rescuing severely dried out plants, some epiphytes
Watering by Plant Type
Tropical Foliage
Monstera, Pothos, Philodendron
When top 1-2 inches dry
Prefer consistent moisture but not soggy. Yellow leaves often mean overwatering.
Succulents & Cacti
Echeveria, Jade, most cacti
When soil is completely dry
Water deeply but infrequently. Err on the side of underwatering.
Ferns
Boston Fern, Maidenhair
Keep consistently moist
Never let dry out completely. Humidity is as important as watering.
Peace Lily, Calathea
Moisture-lovers
When top inch is slightly dry
Sensitive to tap water chemicals. Use filtered or distilled water.
Snake Plant, ZZ Plant
Drought-tolerant
When soil is mostly dry
Very forgiving of underwatering. Root rot from overwatering is the main killer.
Seasonal Watering Adjustments
Spring
Gradually increase watering
Plants exit dormancy and begin active growth, using more water.
Summer
Water more frequently
Heat and longer days mean faster evaporation and more water use.
Fall
Gradually decrease watering
Growth slows as days shorten. Plants need less water.
Winter
Water sparingly
Most plants are dormant. Overwatering in winter is very common.
Signs of Watering Problems
Overwatering Signs
- Yellowing leaves, especially lower ones
- Soil stays wet for many days
- Musty smell from soil
- Soft, mushy stems
- Fungus gnats flying around
- Wilting despite wet soil
Underwatering Signs
- Crispy, brown leaf edges
- Wilting, droopy leaves that perk up after watering
- Soil pulling away from pot edges
- Very lightweight pot
- Leaves curling inward
- Slow growth or no new leaves
Frequently Asked Questions
How often should I water my houseplants?
There's no universal schedule—it depends on the plant, pot size, soil type, humidity, temperature, and season. Most houseplants need watering every 1-2 weeks, but always check soil moisture rather than following a fixed schedule.
Is it better to underwater or overwater?
Underwatering is usually easier to fix. Most plants recover quickly from drought but struggle to recover from root rot caused by overwatering. When in doubt, wait another day before watering.
Should I mist my plants instead of watering?
Misting increases humidity but doesn't water roots—they serve different purposes. You still need to water the soil. Misting can help humidity-loving plants but may promote fungal issues if leaves stay wet.
What's the best water for houseplants?
Room temperature tap water works for most plants. However, some plants (Calathea, Dracaena, Spider Plant) are sensitive to chlorine and fluoride. For these, use filtered water, rainwater, or let tap water sit overnight.
