How to Grow and Care for Philodendron Houseplants

Updated: 19 Sep, 2023


The Philodendron genus encompasses a diverse array of stunning foliage plants, boasting leaves that are characteristically large, vibrant green, and luxuriantly glossy. These botanical marvels effortlessly infuse a touch of their native tropical splendor into any household. Renowned for their undemanding nature, philodendrons offer two distinct categories: vining and non-climbing.

Vining varieties extend gracefully, often necessitating sturdy supports like trellises or hanging baskets. On the other hand, non-climbing counterparts grow upright, making them splendid container plants with their captivating foliage. In terms of growth, philodendrons are notably swift in their development.

Beyond their aesthetic appeal, these plants serve as exceptional air purifiers, enhancing the quality of your indoor environment. While spring is the optimal season for planting, houseplant enthusiasts can embark on this journey with success at virtually any time of the year. It’s important to note, however, that philodendrons are potentially harmful if ingested by pets or humans, owing to their toxic properties.

What Is a Philodendron?

Within the Araceae family, philodendrons stand as one of the most extensive genera. Their physical attributes exhibit a wide spectrum of variations from one species to another, encompassing distinctions in leaf morphology, size, mature dimensions, growth pattern, and foliage hue.

Shared characteristics often include impressive, frequently lobed leaves, lengthy aerial roots, parallel leaf veins, and a consistent progression of leaf transformations throughout their growth stages.

As seedlings emerge, their leaves typically adopt a heart-shaped configuration. With maturation, these leaves transition into an array of shapes, ranging from expansive hearts, resembling lily pads, to pointed arrowheads, and even intricately lobed structures or leaves adorned with perforations and slits.

The etymology of the term “philodendron” traces back to Greek origins: “philo” denoting love and affection, and “dendron” signifying tree. This nomenclature fittingly encapsulates the nature of the majority of species within the genus, as they exhibit a penchant for climbing or trailing, displaying a fondness for growing on or ascending trees.

Common Problems With Philodendron

Philodendrons are remarkably adaptable to indoor environments and are known for their ease of propagation. However, they can experience some health issues if their water, sunlight, and soil requirements are not met. Here are indicators to watch for and steps to address them:

Yellowing Leaves: Yellowing leaves can result from factors like using excessively cold water, insufficient sunlight, or excessive exposure to bright light. Older leaves may yellow due to under-watering, while younger bottom leaves may signal overwatering. Adjust these factors to revive your plant.

When fertilizing your philodendron, take care to water the soil first, apply a diluted fertilizer solution, and then water again. This precaution prevents potential root damage from fertilizer chemicals, which can lead to yellowing.

Yellowing with a Rotting Odor: Sudden yellowing of leaves may indicate root rot. Swift action may save the plant. Check the soil for a foul odor and inspect the roots. Trim away black, decaying sections, and replant healthy portions in fresh soil.

Browning Leaves: Edges browning on the leaves may be a result of using overly cold water. If leaves turn brown and mushy, it’s likely due to overwatering. Curled, brown edges signal the need for more water and less sunlight. Adjust watering and lighting accordingly.

Brown tips with yellow halos suggest a need for higher humidity. Mist the leaves or place the plant container on a tray of water-filled pebbles to elevate humidity. Avoid submerging the base; keep it above the waterline.

Potting and Repotting Philodendrons

To transplant a philodendron, opt for a container slightly larger than its root ball, ensuring it has sufficient drainage holes. Once roots begin protruding from the soil and drainage holes, it’s time for repotting, ideally in late spring or early summer. Choose a pot one size larger. Carefully extract the plant from its current pot, nestling it into the new one with fresh soil at the base and around the edges. Finally, thoroughly water the plant.

Propagating Philodendrons

Propagating philodendrons is an exciting way to expand your plant collection. There are several methods to do so, and here are three common ones:

1. Stem Cuttings:

  • Step 1: Select a healthy parent plant with strong stems and vibrant leaves.

  • Step 2: Using a clean, sharp knife or scissors, take a cutting that is around 4-6 inches in length. Ensure it has at least one or two nodes (small bumps where leaves and roots grow from) on it.

  • Step 3: Remove the leaves from the lower portion of the cutting, leaving only a few at the top.

  • Step 4: Allow the cutting to callus over for a few hours. This helps prevent rotting when it’s placed in soil or water.

  • Step 5: Plant the cutting in a well-draining potting mix or place it in water. If using soil, water lightly.

  • Step 6: Keep the cutting in a warm, indirect light location. If in water, change the water every few days to prevent stagnation.

  • Step 7: Roots should develop within a few weeks. Once they’re well established, transplant the cutting into a larger container or the desired planting location.

2. Air Layering:

  • Step 1: Identify a healthy, mature stem on the parent plant.

  • Step 2: About 12-18 inches from the tip of the stem, make a diagonal cut through the bark, about one-third of the way around the stem.

  • Step 3: Apply a rooting hormone to the cut area (optional, but it can encourage faster root development).

  • Step 4: Wrap the cut section with moist sphagnum moss or a similar rooting medium, and cover it with plastic wrap. Secure the ends to create an airtight seal.

  • Step 5: Wait for roots to form inside the moss, which can take several weeks to a few months.

  • Step 6: Once roots are well established, carefully cut the stem just below the rooted area and plant it in its own pot.

3. Division:

  • Step 1: Choose a mature philodendron with multiple stems or growth points.

  • Step 2: Gently remove the plant from its pot, being careful not to damage the roots.

  • Step 3: Inspect the roots and identify natural separation points or gently pull apart sections.

  • Step 4: Plant each divided section into its own pot with fresh soil.

  • Step 5: Water thoroughly and care for each new plant as usual.
