As temperatures rise during the hot summer months, it’s crucial to pay extra attention to the watering needs of our beloved houseplants. Proper watering is essential for their health and vitality, and neglecting this aspect can lead to wilting, root rot, or even death. In this article, we will explore the best watering practices for houseplants in hot weather. We’ll cover tips and techniques to ensure your houseplants stay hydrated and thrive throughout the summer season. So, let’s dive in!

The short answer is: The best watering practices for houseplants in hot weather include adjusting the watering frequency and checking the soil moisture regularly. Plants may require more frequent watering during the summer to compensate for the higher evaporation rate. It’s important to avoid overwatering and provide the right amount of water based on individual plant needs.

Watering Principles for Houseplants in Hot Weather

To keep your houseplants happy and healthy during hot weather, several key principles apply to watering. These include adjusting the watering frequency, checking soil moisture, using the right type of water, and employing appropriate watering techniques. Let’s explore each principle in detail.

1. Adjusting Watering Frequency

During hot weather, the increased temperature and higher evaporation rate can cause the soil in your houseplant pots to dry out more quickly. It’s essential to adjust your watering frequency accordingly. Keep in mind that different houseplants have varying water requirements, so understanding their needs is crucial. Research your specific plant’s preferences and consider factors such as its size, pot type, and location.

Regularly check the soil moisture by inserting your finger about an inch into the potting mix. If it feels dry at that depth, it’s a signal that your houseplant needs water. However, if the soil still feels slightly moist, it’s best to hold off watering for a bit longer. Overwatering can be just as harmful as underwatering, so finding the right balance is key.

2. Checking Soil Moisture

To get a more accurate gauge of soil moisture, consider using techniques such as the finger test, moisture meters, or moisture indicator strips. The finger test involves inserting your finger into the soil up to the first knuckle. If the soil feels dry, it’s time to water. Moisture meters and indicator strips provide a numerical or visual indication of soil moisture, allowing you to determine if watering is necessary.

Monitoring soil moisture levels is especially important during hot weather when evaporation rates are high. By keeping a close eye on moisture levels, you can make informed decisions about when to water your houseplants.

3. Type of Water to Use

The type of water you use to hydrate your houseplants can also impact their overall health and growth. Rainwater is the ideal choice, as it contains essential nutrients and lacks the chemicals found in tap water. However, if rainwater is not available, tap water can be used after letting it sit for at least 24 hours. This resting period allows chlorine present in the tap water to dissipate, preventing potential harm to the plants.

It’s important to note that if your tap water is softened, it may contain high levels of salt, which can accumulate in the soil over time and harm your plants. Therefore, it’s best to avoid using softened water for watering houseplants.

4. Appropriate Watering Techniques

Choosing the right watering technique is vital for ensuring your houseplants receive the right amount of water and that it reaches their root zones effectively. Some commonly used watering techniques include:

  • Traditional Watering: Use a watering can with a fine nozzle to water the soil around the base of the plants. Water until it starts draining from the pot’s drainage holes and reaches the plant’s roots.
  • Bottom Watering: For plants with sensitive leaves or those prone to fungal diseases, such as African violets, bottom watering is an excellent option. Simply place the pot in a tray of water and allow the plant to soak up the water through the drainage holes until the topsoil feels moist.
  • Soaking: Some plants, such as orchids or bromeliads, benefit from periodic soaking. Submerge the entire pot in a basin or sink filled with water for a few minutes to thoroughly saturate the potting mix. Afterward, allow the excess water to drain before returning the plant to its usual spot.
  • Misting: While misting doesn’t provide direct hydration to the roots, it can help increase humidity levels around houseplants with high moisture requirements. Use a fine mist spray bottle to gently spritz the foliage, taking care not to drench the leaves excessively.

Consider the natural environment and preferences of your houseplants when selecting a watering technique. Some plants, like succulents, may require less frequent watering and prefer dry conditions, while others, such as ferns, thrive in consistently moist environments.

5. Signs of Overwatering and Underwatering

Understanding the signs of overwatering and underwatering is crucial for preventing damage to your houseplants. Here are some common indicators to look out for:

  • Wilting Leaves and Drooping Stems: These are signs that your plants are thirsty and in need of water. However, it’s important to note that wilting can also be a sign of overwatering, so it’s essential to consider other factors, such as soil moisture, before watering.
  • Crispy Brown Leaf Tips: When the leaf tips turn brown and crisp, it may indicate that your plants are thirsty and require water. However, prolonged brown leaf tips can also be a sign of chronic overwatering, causing root rot.

To avoid over or underwatering, regularly assess your houseplants’ condition and adjust your watering routine accordingly. Remember, each plant is unique, and it’s essential to provide individualized care.


To ensure your houseplants thrive during hot weather, implementing the best watering practices is vital. Adjusting the watering frequency, checking soil moisture, using the right type of water, and employing appropriate watering techniques are fundamental principles to keep in mind. Remember to monitor your houseplants closely, observe their responses, and make adjustments as necessary.

By implementing these practices and remaining attentive to the needs of your houseplants, you can create an optimal environment for their growth and well-being throughout the hot summer months.

Remember, in gardening, there are no absolute rules that apply to every plant or every situation. It’s essential to experiment, learn from your experiences, and adapt your practices accordingly. By being attentive and responsive to your houseplants’ needs, you can develop a flourishing indoor garden that brings beauty and joy to your home.
