Propagating Stunning Philodendron Pastazanum Houseplants

An Introduction to Philodendron pastazanum

Philodendron pastazanum, commonly known as Pastaza Philodendron, is a unique and exotic looking houseplant. This Philodendron species is originally from Ecuador and gets its name from the Pastaza region where it was first discovered. With its showy white stems and deep green leaves, Philodendron pastazanum stands out from other more common Philodendrons.

Key Features of Philodendron pastazanum

Philodendron pastazanum is an evergreen perennial plant that can grow quite large when mature. Some key features of this Philodendron species include:

• White stems that can grow up to around 20 ft long
• Oval-shaped dark green leaves measuring around 8 inches long
• A climbing growth habit, using aerial roots to attach itself to trees
• Large showy leaves that give it a tropical look

The striking white stems contrast beautifully against the lush dark foliage. With the right care and environment, Philodendron pastazanum can grow into an impressive statement plant in any indoor space.

Propagating Philodendron Pastazanum

Propagating Philodendron pastazanum is a great way to create new plants from an existing plant. This Philodendron species propagates easily both through stem cuttings and by air layering.

Stem Cutting Propagation

Stem cuttings involve taking a cutting from the plant and rooting it in water or soil. Here is a step-by-step guide to propagating P. pastazanum by stem cuttings:

1. Select a healthy stem that has at least 3 leaves on it and cut it off near the base of the mother plant.
2. Trim off the lowest leaf then place the cutting in a jar of water with the cut end fully submerged.
3. Place the jar in a bright location out of direct sunlight. Change the water weekly to prevent rotting.
4. Roots will begin emerging in 3-8 weeks. Once roots are 1-2 inches long, pot up the new plantlet in a well-draining potting mix.
5. Keep the newly potted cutting humid and shaded as it establishes over the next few weeks.

Air Layering Propagation

Air layering, also called air propagation, is another propagation method that works well for Philodendron pastazanum. It involves encouraging roots to form right on the stem while the stem is still attached to the mother plant. Here is how to air layer this Philodendron species:

1. Select a section of stem that has one or more leaf nodes and trim off some leaves to expose about 2 inches of bare stem.
2. Wrap a handful of sphagnum moss around the area then wrap it fully with plastic wrap to enclose the moss.
3. Once new white roots are visible emerging through the plastic in 4-8 weeks, cut off the newly rooted plantlet right below the plastic wrapped area.
4. Pot up the newly rooted Philodendron pastazanum plantlet and care for it like a new plant.

Caring for Propagated Philodendron Pastazanum

Caring for newly propagated Philodendron Pastazanum plantlets takes patience and attention until they are well established. Here are some tips for getting your propagations off to a strong start:

• Pot in an airy aroid potting mix amended with perlite or orchid bark
• Water whenever the top inch of soil is dry
• Keep humidity high by misting often or using a pebble tray
• Keep out of direct sun until plant is larger and more mature
• Stake or trellis upright as needed while plant establishes
• Resume fertilizing monthly in spring and summer when plant shows new growth

With the right care, your propagated Philodendron pastazanum will grow into an impressive specimen plant adding a unique tropical look to your home.

Troubleshooting Propagation Problems

While Philodendron pastazanum propagates readily, issues can sometimes pop up and prevent success. Here are some troubleshooting tips for common propagation problems with this Philodendron species:

• Rotting cuttings - Use sterile tools, change water frequently, reduce watering amount after potting up
• Few roots forming - Increase ambient humidity and warmth around cuttings
• Leaf yellowing - Move to brighter location, avoid overwatering
• Dropping leaves - Reduce watering frequency, give more gradual transitions when moving plant

Catching issues early allows you to take corrective care measures before losing your new plantlet. With the right adjustments to care, struggling propagations can rebound.

Interesting Varieties of Philodendron Pastazanum

While the classic Philodendron pastazanum has showy white stems and deep green leaves, there are some interesting cultivated varieties to look out for as well.

Conclusion

With its large tropical foliage and contrasting white stems, Philodendron pastazanum has captivated plant lovers around the world. This exotic aroid species propagates readily through stem cuttings and air layering. Caring for the new propagations takes some attention at first but the end reward is more of these fabulous plants. Seek out both the classic species form along with special cultivated varieties for the most diversity in leaf shapes, sizes and stem colors.

FAQs

How big does Philodendron pastazanum grow?

Philodendron pastazanum is a vining plant that can grow quite large and tall in its native tropical habitat. Indoors, grow lights and proper staking/support should allow it to reach heights of 6-10 feet or more over time.

What are the optimal light levels for this Philodendron?

Philodendron pastazanum does best in bright, indirect light. Some early morning or late day direct sun is tolerated. Low light will result in sparse, leggy growth.

What temperature range does this plant require?

Daytime temperatures of 70-85°F and 60-75°F at night suit this Philodendron species best. Keep away from cold drafts. It enjoys the average household temperature range.

Should I mist my P. pastazanum?

Misting your Philodendron pastazanum regularly is great for humidity and mimics its preferred tropical environment. Just be cautious of getting water trapped between thick leaves as that moisture staying put can lead to fungal issues.
