How many times should you water a plant a day?

When it comes to watering houseplants, there is no one-size-fits-all answer. How often you need to water a plant depends on several factors, including the type of plant, its size and container, the climate, time of year, and more. While some general guidelines can help point you in the right direction, closely observing your individual plants and adjusting as needed is key to keeping them happy and healthy.

Quick Answers

As a quick reference, here are some general guidelines for how often to water common houseplants:

  • Succulents: Allow soil to fully dry out between waterings, about once every 1-2 weeks.
  • Cacti: Water every 2-3 weeks, allowing soil to fully dry out in between.
  • Pothos: Water when top inch of soil feels dry, about once a week.
  • Peace lily: Water when top of soil is dry to the touch, about once a week.
  • Chinese evergreen: Water when top inch of soil feels slightly dry, about once a week.
  • Snake plant: Allow soil to dry out some between waterings, about once every 1-2 weeks.
  • Orchids: Water once a week, allowing potting mix to almost dry out between waterings.
  • African violet: Water when top of soil feels dry to the touch, about once or twice a week.

However, these are simply guidelines. Make sure to assess each individual plant’s needs, adjusting your watering schedule accordingly.

Factors That Influence Watering Frequency

There are several key factors that affect how often you should water a houseplant:

Type of Plant

Some types of plants have naturally different watering needs:

  • Succulents and cacti: These plants store water in their leaves, stems, and roots. They prefer staying on the dry side, and can go longer between thorough waterings.
  • Tropical plants: Plants like orchids, peace lilies, and anthurium originate in tropical climates with high humidity. While they don’t like soggy soil, they tend to prefer more frequent watering than succulents and cacti.
  • Ferns and palms: These plants enjoy moist (but not soggy) soil, and appreciate frequent watering.

Pot Size

Plants in smaller pots will need to be watered more often than plants in larger pots. This is because a small volume of soil dries out faster than a large volume of soil.

Type of Pot

Plants in porous, clay pots tend to lose moisture faster than those in plastic or glazed ceramic pots. Consider watering plants in breathable clay pots more frequently.

Plant Size

Larger, more established plants need more water than smaller, younger plants. Prioritize watering your larger plants when their soil dries out before smaller plants.

Time of Year

In warmer months or climates, plants need more frequent watering to make up for moisture lost through transpiration. You may need to water twice as often during summer for some plants.

Sun Exposure & Humidity

Plants in hot, dry, sunny areas or climates will require more frequent watering than plants in cooler, humid, shaded areas where soil retains moisture better.

Soil Composition

Some potting mixes retain water better than others. Soilless potting mixes often contain peat moss or coconut coir to help hold onto moisture. Heavier garden soils drain more slowly. Very quick-draining cactus mixes will require more frequent watering for non-succulents.

Container Drainage

Always make sure your plant’s container has adequate drainage holes. Plants sitting in saucers filled with water will become oversaturated. Prioritize watering plants without saucers more frequently.

Evaporation

While indoor plants won’t dry out as quickly as outdoor plants, you may need to water them more often if you have heating or cooling vents nearby that speed up evaporation.

Plant Health & Growth

Plants that are rapidly growing, or stressed plants making a comeback, might need more frequent hydration to fuel their growth. Established, dormant or semi-dormant plants need less water.

How to Tell When Your Plant Needs Water

While the above guidelines can help point you in the right direction, the best way to know if your specific plant needs water is to check its soil moisture and observe the plant’s appearance.

Check Soil Moisture

Stick your finger into the top inch or two of soil and feel for moisture. You can also use a moisture meter for a more precise reading.

  • If soil is dry and crumbly, it’s time to water.
  • If soil feels slightly dry but still clumps together, you can wait a day or two.
  • If soil feels soggy or wet, hold off on watering.

Look for Visual Cues

In addition to feeling the soil, observe the plant’s appearance for signs of thirst:

  • Wilting or drooping – The plant needs water ASAP.
  • Leaves curling inward – This can indicate underwatering.
  • Brown leaf tips – A sign of mild drought stress.
  • Less glossy or vibrant leaves – Leaves may appear dull when thirsty.
  • Slowed growth – Dry soil can limit a plant’s growth.

Plants with plump, perky leaves are typically hydrated. But the best indicator is checking soil moisture directly.

Learn Your Plant’s Cues

Pay attention to how your individual plant signals when it needs to be watered. With time, you’ll learn to read its specific signs of thirst.

Tips for Watering Houseplants

Follow these tips to hydrate your houseplants properly:

  • Water plants thoroughly until water drains from the bottom of the pot. This ensures water reaches the entire root zone.
  • Pour water directly onto the potting mix. Avoid getting water on leaves, which can promote disease.
  • Use room temperature water – cold water can shock a plant’s roots.
  • Always empty any water from the plant’s saucer after 30 minutes.
  • Consider grouping plants with similar needs to streamline watering.
  • Establish a consistent watering schedule based on each plant’s needs.
  • Adjust your schedule for seasonal changes or growth periods.
  • Avoid overwatering – only water when soil is somewhat dry.

Signs You’re Overwatering

It’s important to not overdo it when watering houseplants. Too much moisture can be just as damaging as too little. Watch for these signs of overwatering:

  • Spots or patches of yellow, brown, or black on leaves
  • Soft, mushy leaves or stems
  • Wilting leaves, even with moist soil
  • Excess algae or mold on soil surface or pot
  • Foul odor from potting mix
  • Slow plant growth
  • Leaves falling off
  • Roots rotting – turn brown/mushy

If you suspect you’re overwatering, cut back on frequency and ensure pots have drainage. Add amendments like perlite to improve drainage for chronic overwatering issues.

Conclusion

There are many factors to consider when deciding how often to water houseplants. While general rules can provide a helpful starting point, pay close attention to each individual plant’s needs and cues. With experience, you’ll learn to read your plants and recognize when they need to be quenched. Aim for a thorough soak whenever the top inch of soil dries out, then allow time for excess moisture to drain away before the next watering. Adjust frequency based on season, growth rate, plant type, pot size, and your environment. Consistency is key – set up a schedule tailored to each plant. With proper hydration, your houseplants will thrive indoors!
