Pothos, also known as devil’s ivy, is a popular houseplant that is easy to care for. Knowing when to water your pothos is important for its growth and health. In this article, we will explore the best watering practices for your pothos plant.

Understanding Pothos Plant Watering Needs

Watering Frequency

Pothos plants thrive when their top 2-3 inches of soil dry out between waterings. To maintain the ideal moisture level, it’s crucial to check the soil twice a week and water the plant accordingly. During warmer months, you may need to water pothos 2-3 times more frequently than during their dormancy period1.

Signs of Overwatering and Underwatering

Overwatering can contribute to root rot issues in pothos plants. Here are some signs of overwatering:

  • Yellow leaves
  • Wilting despite moist soil
  • Root rot

To avoid overwatering, always empty the tray underneath the plant and ensure it doesn’t sit in water for too long.

Underwatering, on the other hand, can also cause problems for pothos plants. Some common underwatering symptoms include:

  • Yellow leaves
  • Wilting with dry soil
  • Brown leaf edges

An easy method to determine if your plant needs water is by using the “finger check” method. Simply insert your finger about an inch into the soil, and if it feels dry, it’s time to water your pothos. If the soil is moist, wait a few days before rechecking.

Another useful tool to monitor your pothos plant’s moisture level is a moisture meter. Insert the probes of the moisture meter into the soil near your plant, ensuring they are in contact with the root zone. After a few minutes, the moisture meter will provide a reading, helping you identify whether it’s time to water your pothos.

By understanding how often and when to water your pothos plant, you can ensure its optimal growth and maintain its overall health.

Using Moisture Meters for Pothos

Benefits of Moisture Meters

Using moisture meters for pothos plants offers several advantages:

  • Accurate measurement: A moisture meter provides precise readings of the soil’s moisture level, ensuring that the plant is watered properly and preventing over- or underwatering.
  • Consistency: By regularly monitoring the soil moisture using a moisture meter, you can maintain a consistent watering schedule that caters to the needs of your pothos plant.
  • Adaptability: Environmental factors like humidity and light levels can impact the watering frequency. A moisture meter helps you adjust the watering schedule based on the specific conditions in your home.

Selecting the Right Moisture Meter

To successfully use a moisture meter for your pothos plant, you need to select the right one. Keep these features in mind while selecting a moisture meter:

  • Ease of use: Ensure that the moisture meter is user-friendly, with clear and easy-to-read measurements.
  • Durability: Choose a moisture meter that is built to last, as it will be exposed to water and soil on a regular basis.
  • Probe length: The probe should be long enough to reach the plant’s root zone, providing accurate readings of the soil’s moisture level.

When using a moisture meter, insert the probes into the soil near your pothos plant, ensuring that they make contact with the root zone. Wait a few minutes for the meter to take a reading. Look for a reading of 2-3 on the moisture meter to indicate that your pothos is ready for watering. By maintaining the soil moisture within the ideal range using a moisture meter, you can ensure that your pothos plant stays healthy and thrives.

How to Use a Moisture Meter

Proper Insertion and Reading

When using a moisture meter to determine the watering needs of your pothos plant, begin by inserting the probes of the meter into the soil near the base of the plant. Ensure the probes are deep enough to reach the root zone of the plant, which is essential for accurate moisture measurement. Once the probes are in place, wait for a few minutes so the moisture meter can take a reading.

Interpreting Results for Pothos Watering

Interpreting the results from the moisture meter involves understanding the readings for optimal pothos watering. A moisture level reading of 2-3 on the meter is an ideal indicator that your pothos is ready for watering. This typically corresponds to the top 1-2 inches of soil feeling dry to the touch. To maintain a healthy pothos plant, aim to water it once every week during the summer months when sunlight absorption is higher, requiring more frequent watering.

Keep in mind that moisture meters measure the conductivity of the soil using electrical resistance—higher electrical currents indicate moist soil, while lower currents suggest drier soil conditions. By regularly monitoring the moisture levels in the soil using a moisture meter, you can ensure that your pothos plant receives the necessary care and watering for optimal growth and health.

Tips for Pothos Watering Success

Watering Techniques

To ensure your pothos plants stay healthy, pay close attention to their watering needs. Generally, it is best to allow the soil to dry slightly between waterings in order to avoid overwatering. A good rule of thumb is to check if the top 1-2 inches of soil feels dry, and if so, it’s time to water your pothos. Using a moisture meter can also help with this task—when the reading is around 2-3, it indicates that your pothos is ready for a drink.

When watering pothos, it’s best to avoid getting the leaves wet, as this can lead to various problems. Instead, use a long-spouted watering can or a drip system to water the plant from below. This way, you ensure the roots receive adequate moisture without causing leaf damage.

Indoor and Outdoor Pothos Care

Both indoor and outdoor pothos plants require similar care, but there are a few key differences. Indoor pothos typically require less frequent watering than their outdoor counterparts due to the lower levels of light and temperature fluctuation. Watering every 1-2 weeks should suffice, adjusting according to the light conditions—more frequent watering for bright light and less frequent for low light situations.

Outdoor pothos may require more frequent watering, especially during the summer months when the sun absorbs a significant amount of moisture. Be sure to monitor the moisture level in the soil and adjust your watering schedule accordingly.

During the winter months, it is important to cut back on watering for both indoor and outdoor pothos plants. The soil should be allowed to dry out more than usual before re-watering. As temperatures drop and sunlight decreases, the plant’s growth rate slows, leading to a reduced need for hydration.

Following these tips and adjusting your watering techniques based on the specific needs of your indoor or outdoor pothos plant will help ensure their growth and overall health.
