For instance:

  • It is possible to use a basic potter’s mix that has peat moss to aid in drainage.
  • It is also possible to use the cactus mix and perlite to aid in drainage and retention of moisture.

Philodendron Giganteum Light Requirement

Philodendron giganteum is a simple plant to cultivate and thrives in indirect sunlight. It is actually one of the plants that can thrive in shade since it is able to photosynthesis even at extremely low levels of light.

However, philodendron giganteum require a lot of indirect sunlight. If they are exposed to too much light, the leaves will change to into a lighter shade of green or the leaves could burn. Don’t place it in a place that receives the sun’s direct beams.

  2. Cut off dead or damaged stems, leaves, or roots. Use an oblique, tidy garden shears or a pair of scissors.
  3. Release the root ball beginning from the bottom and work upwards. It is essential to do this prior to placing your plant into the new container, since once it’s in the container, it is difficult to remove without harming the root system or leaves of the philodendron giganteum plant.
  4. Apply an even layer of potting soil on the bottom of the container. It should be moist but not wet.
  5. Plant your philodendron giganteum in its new container and plant it in soil. The soil could also be damp.


The ideal season to propagate Philodendron is in the summer and spring months however, you can also propagate them at almost anytime.

The process of propagating a philodendron is simple and you can turn one plant into several. Philodendrons are able to grow from stems So all you require is an incredibly sharp knife, some rooting hormoneand pot dirt or even water.

Propagating Philodendrons Giganteum

Begin the propagation process with the water or in a well-drained soil. Here’s how:

Things you’ll need

  • Philodendron cutting
  • Sharp knife
  • Rooting hormone
  • Potting soil or jars of water
  1. Cut a piece of the stem of the mature Philodendron giganteum parent plant. It is possible to do this by cutting off a healthy limb using the help of two to three leaves at approximately 10-centimeters (4 inches) long.
  2. Make use of sharp garden shears or scissors for this step. Be sure to remove all leaves from the lower portion of the stem to ensure that you don’t harm the parts of the stem in soil or water at following steps.
  3. Place your cut in the water with glass jars, with enough space for the roots to develop. Replace the water every second day.
  4. If you are planning for your new plant to be planted into soil, choose an potting mix that is well drained. Keep the cut in a cool area and away from direct sunlight for about 4-6 weeks.

The cutting will root and then begin to produce new growth. When you notice the new growth, you can relocate your plant into a more bright spot, but keep it away from direct sunlight.


The plant is able to be cut back at any point of the year without any fuss. However, it is best to wait until the new growth begins to appear prior to trimming the philodendron, so you know the areas where it will grow branches.

Here’s how to trim your plant:

  1. The philodendron should be watered thoroughly to ease cutting, then trim the large leaves using sharp pruning shears or scissors. Cut the stem of the leaf 2 inches (5.08 cm) lower than the base of the leaf. Leave the smaller leaves uncut to ensure that your philodendron doesn’t get top heavy with excessive foliage. It could topple over.
  2. Cut off dead branches and stems as close as you can to the point of their beginning without cutting into living tissue. This will stimulate your philodendron to grow from this region while keeping its original shape.

If you’re cutting back a plant that is overgrown remove one-third of the stems that were once used cutting each one just above the leaf node (the point at which a leaf joins the stem).

Common Problems With Philodendron Giganteum

Philodendron giganteum can be affected by a variety of bugs and issues.

They include:

  • The leaves are turning yellow due to the water submerging
  • The root rot is caused by excessive watering
  • Pests like mealybugs, spider mites and Fungus Insects such as gnats

Here’s how to recognize these issues so that you can take action when they occur.

Yellow or Brown Leaves

The most frequent reason for brown or yellow leaves on a philodendron is a lack of water. The plant is likely to lose the lower leaf first, and if the issue is not addressed promptly, it could cause the plant to die.

Examine the soil’s moisture then allow the upper layer to dry out after watering, if this happens. If the soil is still soggy then repot it with a new potting mix.

Root rot is a different problem where the stems turn dull and yellow with water-soaked, soft spots that become into a mushy black color as the plant begins to rot.

One method of detecting root rot is to observe that the roots change dark brown and slimy. If this occurs you should cut them off using an sterile knife or cutting board prior to planting them again.


The result of underwatering is crisp or brown tips on the leaves. It is typically caused by dry air or the absence of water.

To solve the issue to solve the issue, you can increase the humidity by placing a humidifier close to the plant, spraying the plant every day, or placing the plant in a pebble tray filled with water.

Not Enough Sunlight

Philodendron giganteum is best when it is in bright, but in indirect lightor shade.

The direct sunlight can burn the leaves, making them brown and crisp.

The foliage will change color and turn dry.

Treatment: Spray with insecticidal soap or water to control spider mites.


Mealybugs are tiny, white insects that feed on sap from plants.

They attack a variety of plants. They usually appear as a white fluffy bunch on the stems or the undersides of leaves.

Mealybugs can weaken a plant leading to a decrease in growth.

Treatment: Remove infested plants , and apply the neem oil or other horticultural oil sprays in accordance with the instructions of the manufacturer for controlling pests.

Fungus Gnats

The flying bugs feed off hairs of the root and can cause root rot if not taken care of.

Make sure to water less often or at the base of the plant instead of using overhead watering. The yellow trap can assist in catching them prior to laying eggs. It will also provide an early warning that you might be suffering from an infestation.

Treatment: Separate the plants that are infested from healthy plants immediately you spot symptoms of infestation, to ensure the pests do not spread.
