Watering and Humidity

This plant species has specific watering and humidity requirements to ensure its health and growth. Here are some guidelines to follow:


  1. Soil Moisture: Philodendron giganteum prefers slightly moist but well-draining soil. Allow the top inch or so of the soil to dry out between waterings, but avoid letting it completely dry or become overly saturated.
  2. Watering Frequency: Water the plant thoroughly when the top inch of the soil feels dry to the touch. Ensure that water drains freely from the pot to prevent waterlogging.
  3. Avoid Overwatering: Overwatering can lead to root rot and other issues. Always check the soil’s moisture level before watering to prevent excessive moisture retention.


  1. Moderate to High Humidity: This big-leaved plant appreciates moderate to high humidity levels, mimicking its natural rainforest habitat. Ideally, aim for a humidity level of 60% or higher.
  2. Humidity-Boosting Methods: You can increase humidity by misting the leaves with water, placing a humidifier nearby, using a pebble tray filled with water under the plant, or grouping plants to create a microclimate.
  3. Avoid Low Humidity: Dry air can lead to brown leaf tips or edges. If your indoor environment has low humidity, it’s beneficial to implement measures to raise the humidity level around the plant.

It’s important to note that while Philodendron giganteum appreciates higher humidity, it is also relatively tolerant of average household humidity levels. It should thrive by providing regular watering and maintaining a moderately humid environment.

Observing the plant’s response and adjusting water requirements and humidity practices can help ensure the best conditions for your Giganteum.


Fertile soil is an essential aspect of its care to promote healthy growth and vibrant foliage.

Here are some guidelines for fertilizing this plant:

  1. Frequency: During the growing season, which typically spans spring and summer, you can fertilize Philodendron giganteum every 2-4 weeks. This helps provide a steady supply of nutrients to support its growth.
  2. Dilution: Use a balanced, water-soluble fertilizer- specifically houseplant fertilizer. Follow the instructions on the fertilizer package for the appropriate dilution ratio. It’s generally recommended to use a slightly weaker concentration than what is specified on the package to avoid over-fertilizing. You can also use organic fertilizers such as worm castings.
  3. Application Method: Apply the diluted fertilizer directly to the soil around the base of the plant, avoiding direct contact with the leaves. This helps prevent potential leaf burn and allows the roots to absorb the nutrients. Improper care could lead to burn or even death.
  4. Watering: After fertilizing, water the plant thoroughly to ensure the fertilizer is evenly distributed and to prevent the buildup of salts in the soil.
  5. Winter Rest Period: During the winter months, Philodendron giganteum enters a period of slower growth. Therefore, reducing or suspending fertilization during this time is generally best to align with the plant’s natural growth cycle.

Tip: Always monitor the plant’s response to fertilization and adjust accordingly. If you notice signs of over-fertilization, such as salt buildup or leaf burn, flush the soil with plain water to help leach out any excess salts.


While attractive, Philodendron giganteum, like many other plants in the Philodendron genus, is considered toxic to humans and pets if ingested. Here’s some information regarding its toxicity:

Philodendron giganteum contains calcium oxalate crystals in the plant’s leaves, stems, and sap. When these crystals come into contact with mucous membranes or are ingested, they can cause irritation and discomfort.

Symptoms of toxicity may include oral irritation, lips, tongue, or throat swelling, difficulty swallowing, and stomach upset.

Precautions: If you have Philodendron giganteum in your home or garden, it’s essential to take precautions to prevent accidental ingestion or contact, especially if you have children or pets.

Here are a few guidelines to follow:

  1. Keep out of reach: Place the plant in an inaccessible area to children and pets, or consider hanging it from a ceiling hook or placing it on high shelves.
  2. Education: Teach children and other family members about the potential toxicity of the plant and the importance of not touching or ingesting any part of it.
  3. Pet safety: Be mindful of pets’ curiosity and tendency to chew on plants. Keep Philodendron giganteum out of their reach, and if you notice any signs of ingestion, contact a veterinarian immediately.
  4. Handling precautions: When handling the plant, wearing gloves is advisable to avoid direct contact with the sap or any broken parts. If you come into contact with the sap, wash the affected area thoroughly with soap and water.

While Philodendron giganteum’s toxicity should be taken seriously, it’s worth noting that severe reactions are rare, and most incidents result in minor discomfort.

However, if any symptoms of ingestion or irritation occur, it’s essential to seek medical attention or consult with a healthcare professional.

Growth Rate

The growth rate of Philodendron giganteum can vary depending on various factors such as environmental conditions, care provided, and individual plant characteristics.

Generally, Giganteum Philodendron is known for its vigorous growth and can develop into a plant of massive size in a bit of time. However, it’s important to note that the growth rate may differ from plant to plant.

Under optimal conditions, it typically produces new leaves regularly and can develop a substantial size within a few years.

However, patience’s essential as the growth rate may slow down in less-than-ideal conditions or during the winter months when the plant is dormant.

Factors influencing the plant’s growth rate include ample sunlight, proper amounts of water, balanced fertilization, suitable temperatures, average humidity levels, and good airflow.

Propagation of Philodendron Giganteum

Philodendron GiganteumPropagating my Philodendron Giganteum has been a fun and rewarding experience for me.

Philodendron giganteum typically grows from a single stem and does not naturally have multiple stems or branches. As the plant matures, it may produce new stems and leaves from the center of the plant, gradually creating a fuller and more bushy appearance. This can last a very long time, so you may have to be extremely patient.

Selecting a healthy stem with several nodes when propagating Philodendron giganteum through stem cuttings is vital. By taking a central stem cutting from the main plant and providing the right conditions, new aerial roots can develop from the cutting, eventually growing into a new individual plant.

Here are the methods I have used to propagate this plant:

Stem Cutting

One way to propagate Philodendron Giganteum is through stem cuttings. I have found that stem cuttings work best when they are taken in the spring or summer. Here are the steps I follow:

  1. Choose a healthy stem with at least two leaves.
  2. Cut the stem just below the lowest leaf node.
  3. Remove the lower leaves to expose the node.
  4. Dip the cut end of the stem in the rooting hormone.
  5. Plant the stem in moist soil, covering the node.
  6. Keep the soil moist and place the cutting in a bright, indirect light.

Within a few weeks, root development should start to form, and new growth should emerge.


Another way to propagate Philodendron Giganteum is through division. This method works best in the spring or summer. Here are the steps I follow:

  1. Carefully remove the plant from its pot.
  2. Gently separate the root ball into two or three sections.
  3. Plant each section in a separate pot with fresh soil.
  4. Water the newly potted sections and place them in a bright, indirect light.

Within a few weeks, new growth should emerge from each section.

Propagation is a great way to share your love of Philodendron Giganteum with others. Whether you propagate through stem cuttings or division, it is a fun and rewarding experience that can lead to beautiful new plants.
