Sharing is caring!

During the hot summer months, caring for your peace lily plant requires a bit more attention, especially when it comes to watering. As temperatures rise and humidity fluctuates, you need to ensure your peace lily gets just the right amount of water to thrive. Peace lilies are lovely houseplants known for their lush foliage and striking white blooms, making them an attractive addition to any indoor space. In this article, we’ll discuss how often to water your peace lily in the summer.

To maintain a healthy peace lily during the summer season, you should aim to water it about once a week. However, various factors such as the size of the plant, the soil mix, temperature, and humidity can affect how often you need to water your peace lily source. Always check the soil before watering and ensure that the top two inches of soil are dry before giving it a good soak.

Keep in mind that peace lilies should receive around one inch of water, and the top layer of soil should always remain moist source. To check if your peace lily needs watering, perform a simple finger test by pushing your finger about an inch into the soil. If the soil feels dry at the tip of your finger, it’s time to water your plant. Remember that peace lilies prefer being under-watered rather than overwatered, so avoid saturating the soil too much.

Understanding Peace Lily’s Water Needs

Peace lilies are beautiful indoor plants, but it’s crucial for their health to understand their water needs, especially during the summer months. These plants thrive in moist soil, but they prefer to be slightly under-watered rather than over-watered.

During the summer, peace lilies may require more frequent watering as temperatures increase and soil dries out faster. It’s essential to water them when the top inch of soil has dried out, which typically happens once a week. However, you should always perform a finger test to check the soil moisture before watering, as the frequency may vary depending on your individual plant’s environment.

To successfully water your peace lily, make sure to:

  • Allow tap water to sit out for a day or two, allowing harmful chemicals like fluoride to dissipate. This prevents potential damage to your plant (source).
  • Water the plant until the top layer of soil is moist, usually about one inch deep (source).
  • Monitor the plant for signs of thirst, such as droopy leaves (source). Peace lilies usually bounce back quickly once they receive proper hydration.

Observing your peace lily’s environment is vital for maintaining appropriate watering schedules. Factors such as container size, soil drainage, and room humidity can affect how often you need to water your plant. If you notice water running straight through the pot, your peace lily may be root-bound, which indicates that it’s time to repot the plant (source).

In summary, it’s essential to pay attention to your peace lily’s unique needs during the summer months. Regularly checking the soil moisture and giving your plant a proper drink when needed will help it thrive in its environment.

How Often to Water Peace Lily in Summer

Indoor Peace Lilies

During the summer, indoor Peace Lilies typically require watering once a week. Ensure that the top layer of soil remains moist, which can be determined using a simple finger test. It’s important to avoid letting the soil dry out for extended periods, as this can harm your plant. The amount of water needed may vary slightly based on factors like temperature, humidity, and the size of your plant. Providing around one inch of water per week should usually suffice to maintain the plant’s health.

Outdoor Peace Lilies

For outdoor Peace Lilies, the summer heat and dry conditions often require more frequent watering. In particularly hot temperatures, the plant can quickly run out of water, which necessitates more consistent monitoring of the soil’s moisture levels. Watering at least once a week is still a good baseline, but it’s essential to adjust the frequency as needed based on the specific weather conditions and soil conditions.

In conclusion, for both indoor and outdoor Peace Lilies, maintain proper watering habits during the summer to ensure their overall health and growth. Adjust your watering frequency based on factors like temperature, humidity, and the plant’s specific needs, but remember to avoid over-watering, as it can lead to root rot and other issues.

Factors Affecting Watering Frequency

Pot Size and Type

The size and type of pot in which you grow your peace lily can significantly impact how often you need to water the plant. Larger pots retain more moisture, meaning you may need to water less frequently. On the other hand, smaller pots can dry out more quickly, requiring more frequent watering. Additionally, the material of the pot, such as plastic or porous materials like terracotta, can affect water retention and evaporation rates.


Peace lilies thrive in environments with moderate to high humidity levels, ideally around 60% or higher. Low humidity levels can cause the leaves to develop brown tips and curl up. Consequently, it’s essential to maintain the right humidity and adjust your watering frequency accordingly. In drier environments, you might need to water more frequently or use a humidifier to maintain consistent moisture levels.


The frequency of watering your peace lily during the summer can vary depending on the temperature of your location. Warmer temperatures increase the rate of evaporation, which means the soil will dry out faster. In hotter climates or particularly dry environments, you may need to water your peace lily every 1-2 days. Make sure to monitor the soil moisture and adjust your watering schedule according to the specific needs of your plant.

Soil Type

The type of soil you use for your peace lily plays a crucial role in determining the watering frequency. A well-draining soil mix helps retain adequate moisture while preventing overwatering. Consider using a mix of peat moss, perlite, and potting soil for optimal moisture retention without water logging. Check the top inch of soil regularly, and water your peace lily when the surface is dry but the soil underneath remains moist. This approach helps prevent both overwatering and underwatering, ensuring your peace lily remains healthy and vibrant throughout the summer months.

Signs of Over-Watering or Under-Watering

Maintaining the correct watering schedule for your peace lily is crucial, especially in the summer months. Recognizing the signs of over-watering and under-watering can help you adjust your care routine and ensure your peace lily thrives. In this section, we’ll discuss the key symptoms of both over-watering and under-watering.

Over-Watering Signs

With peace lilies, it’s better to err on the side of underwatering than overwatering. However, it’s still important to recognize the signs of over-watering. These include:

  • Browning edges on the leaves: This occurs when excess water causes the veins at the edges of the leaves to burst, resulting in browning.
  • Wilting leaves: Surprisingly, wilting can be a symptom of both over-watering and under-watering. If wilting occurs with other signs of over-watering, it’s likely due to excess moisture.

Under-Watering Signs

On the other hand, under-watering can also lead to issues with your peace lily. To ensure your plant remains healthy, keep an eye out for the following signs:

  • Yellow or brown spots on the leaves: This can indicate dehydration, as the plant is unable to retain sufficient moisture.
  • Wilting leaves: As mentioned earlier, wilting can be a result of both over-watering and under-watering. Check the soil moisture level to determine the cause.
  • Dry, crumbly soil: If the soil around your peace lily feels dry and doesn’t hold together when squeezed, it’s likely under-watered.

To address under-watering, simply water the plant and observe its response over the next 12-24 hours. A properly hydrated peace lily should recover quickly and display healthier foliage. In the summer months, monitor your peace lily’s condition closely, and adjust its watering schedule as necessary to ensure optimal growth and health.

Tips for Proper Watering Techniques

Watering peace lilies properly during the summer months can help them thrive. It’s essential to understand how to water these beautiful plants to ensure their health and growth. Here are some essential tips for proper watering techniques for peace lilies.

One of the primary steps to take when watering peace lilies is to check the soil’s moisture levels. A good rule of thumb is to water the plant only when the top two inches of soil are dry. This practice helps prevent over-watering and root rot. To check the soil moisture, insert your finger into the dirt up to the second knuckle. If it feels dry, it’s time to water.

During the summer, peace lilies generally need to be watered once a week. However, factors like temperature, humidity, and soil type may impact how often you need to water your plant. For instance, hot and dry summers might require more frequent watering to maintain optimal soil moisture levels.

When watering your peace lily, it’s best to use tap water that has been allowed to sit for a day or two. This step helps dissipate any harmful chemicals, such as fluoride, that could potentially harm the plant. Pour the water slowly and evenly around the base of the plant, taking care not to dislodge soil or disturb the roots.

Monitoring your peace lily for signs of dehydration helps determine whether it needs to be watered more frequently. Look for these signs:

  • Leaves starting to sag or droop
  • Soil pulling away from the edge of the pot
  • Brittle or yellowing leaves

To maintain a healthy peace lily during the summer, keep it in a well-draining pot to avoid standing water. If water runs straight through the pot, it may indicate that the plant is badly root bound and needs to be repotted.

By following these tips for proper watering techniques, you can ensure that your peace lily stays healthy and vibrant throughout the summer months.


In conclusion, peace lilies require consistent and attentive care, particularly during the summer months. Their needs vary based on factors such as climate and container size, so understanding how to best provide for them is essential.

An important aspect of peace lily care is to water them once per week, ensuring around one inch of water reaches the roots. Check the top layer of soil for moisture by performing a finger test, and avoid letting it dry out for extended periods.

Another consideration is the difference in hydration necessary for peace lilies during summer weather. As mentioned earlier, the container size and climate greatly determine the watering frequency. Smaller pots may need more frequent waterings, while adjusting for local conditions and monitoring soil moisture is paramount.

Keep in mind that while tap water is generally suitable for peace lilies, you can allow the water to sit for a day or two for harmful chemicals, like fluoride, to dissipate. Make sure the plant isn’t root-bound, as that could cause water to not adequately reach the roots, necessitating repotting.

Remember not to make exaggerated claims regarding your lily’s watering needs. Staying informed and proactive in your approach to care will ensure that your peace lily thrives in summer and throughout the year.
