A Guide to Watering Philodendron Plants

Philodendrons are immensely popular indoor houseplants that are known for their lush green leaves and easy to care for. One most important aspects of their care is a proper watering routine. Knowing the right frequency of watering your Philodendron plants is critical for maintaining their well-being and promoting their healthy growth.

How Often to Water Philodendrons?

The frequency of watering philodendron plants largely depends on various factors, including environmental conditions, potting mix, pot size, and plant maturity. It is important to note that there is no one-size-fits-all approach to watering philodendrons, as each plant and its surroundings are unique. However, certain guidelines can help you develop an effective watering schedule.

Factors to Consider for Watering

Several factors influence the watering needs of philodendron plants. The key factors to consider are:

Environmental Conditions

The temperature, humidity, and air circulation in your home impact how quickly the potting mix dries out. Higher temperatures and low humidity levels lead to faster evaporation and, consequently, more frequent watering.

Soil Mix and Pot Size

The potting mix’s composition is important and plays crucial role in water retention. Well-draining soil with a mix of organic matter, such as peat moss or coconut coir, and perlite or vermiculite allows excess water to drain away, preventing root rot. Larger pots generally retain more moisture, so the watering frequency may be lower compared to smaller pots.

Plant age

Younger philodendrons typically have smaller root systems and, consequently, require less water. As the plant grows and develops a more extensive root network, its water requirements increase.

Seasons

For Philodendrons, you have to make different watering routines in different seasons. From spring to late summer philodendron is in a growing stage so it’s required frequent watering when the plant is actively generating fresh leaves. In contrast, during fall and winter it’s in the dormancy stage so less watering is required.

How Much to Water Your Philodendrons?

Determining the right amount of water to give your philodendrons is equally important as watering frequency. Overwatering or underwatering can both have adverse effects on the plant’s health.

When watering your philodendrons, the goal is to moisten the entire root ball without leaving it soggy. For proper plant watering, aim to water the plant until water seeps from the drainage holes, ensuring the roots receive enough moisture. Nevertheless, refrain from letting the pot immerse in standing water, as doing so can trigger root rot.

Determining the necessary amount of water to give to a plant relies on various aspects including the size of the pot and the plant as well as the environmental conditions. To ensure that your plant is receiving the appropriate amount of moisture, it’s essential to assess the soil moisture level by inserting your finger about an inch into the potting mix. If you sense dryness at that depth, it’s time to water. In contrast, if it feels wet, it’s best to wait for a little while longer before watering it again.

Types of Water

The type of water you use can also impact the health of your philodendrons. Here are three common types of water and their suitability for watering philodendron plants:

Tap Water:

Tap water is generally safe for philodendrons unless it is excessively hard or contains high levels of chlorine or fluoride.
