Philodendron Atabapoense: The Exotic Climbing Aroid

Introduction:

The Philodendron Atabapoense is a rare, climbing aroid with elongated, spear-shaped leaves. The deep green upper surface of the leaves contrasts beautifully with the reddish-purple undersides, creating a dramatic look. As a climbing plant, it grows well when provided with support, such as a moss pole or trellis, which allows its leaves to grow larger and more defined.

History:

Native to the tropical rainforests of South America, particularly around the Atabapo River, this philodendron thrives in humid, warm environments where it climbs trees to reach sunlight. It has recently gained popularity in the houseplant community due to its rare and unique appearance, particularly the contrast between its dark green upper leaves and reddish undersides.

Care Outline:

• Light: Philodendron Atabapoense thrives in bright, indirect light. It can tolerate lower light conditions but will grow more vigorously and produce larger leaves with better color contrast in bright, filtered light. Avoid direct sunlight, which can scorch its delicate leaves.

• Water: Water when the top 2–3 inches of soil are dry. This philodendron prefers evenly moist soil but is susceptible to root rot if left in soggy conditions. Ensure that the pot has good drainage to allow excess water to escape.

• Humidity: Philodendron Atabapoense enjoys high humidity, ideally around 60%–80%. If grown indoors in a dry environment, a humidifier or regular misting will help maintain optimal moisture levels.

• Temperature: This plant prefers warm temperatures between 65°F to 80°F (18°C to 27°C). It should be kept away from cold drafts and protected from temperatures below 50°F (10°C), as it is sensitive to cold.

• Soil: Use a well-draining aroid mix composed of orchid bark, perlite, and peat moss or coconut coir. This will mimic its natural environment and ensure proper drainage while retaining some moisture for the roots.

• Fertilizer: Feed the plant every 4–6 weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer. Reduce feeding during the fall and winter months when the plant’s growth slows.

• Climbing Support: Since Philodendron Atabapoense is a climbing plant, it will benefit from a moss pole or trellis, which helps it grow upward and develop larger, more mature leaves.

Light Requirements:

Philodendron Atabapoense thrives in bright, indirect light for optimal growth. If grown in lower light conditions, the plant may grow slower, and the reddish coloration on the leaf undersides may not be as vibrant.

• Natural Light: Place the plant near an east-facing or north-facing window where it will receive bright, filtered light without being exposed to direct sunlight.
• Artificial Light: If natural light is limited, use grow lights to supplement, providing 12–14 hours of light per day to maintain healthy growth.

Propagation:

1. Stem Cuttings:

• Best Time: Spring or early summer, during the growing season.
• Steps:
  1. Take a cutting that includes at least one node and a healthy leaf.
  2. Place the cutting in water or plant it directly into moist, well-draining soil.
  3. Keep the cutting in a warm, bright area with high humidity.
  4. Roots should form in a few weeks, and once established, the cutting can be transferred to a larger pot.

Soil for Philodendron Atabapoense:

A well-draining, airy soil mix is essential to keep the plant’s roots healthy. A good aroid mix for Philodendron Atabapoense includes:

• Orchid bark to improve aeration and support.
• Perlite to ensure proper drainage.
• Peat moss or coconut coir to retain moisture while avoiding waterlogging.

This mixture mimics the plant’s natural growing environment and supports healthy root growth.

Fertilizing:

• Fertilize every 4–6 weeks during the active growing season with a balanced, water-soluble fertilizer.
• Reduce fertilizing during fall and winter when growth slows.
• Avoid over-fertilizing, as it can lead to nutrient burn and harm the plant.

Repotting:

• When to Repot: Repot every 1–2 years, or when the plant outgrows its pot.
• Best Time: Spring is the best time to repot, just before the growing season starts.
• Steps:
  1. Carefully remove the plant from its pot and check the roots.
  2. Repot into a slightly larger pot with fresh, well-draining soil.
  3. Water thoroughly after repotting and place the plant in bright, indirect light to adjust.

Pests and Diseases:

Like most houseplants, Philodendron Atabapoense is prone to pests such as spider mites, mealybugs, and scale. Regularly inspect the leaves for any signs of infestation and treat with insecticidal soap or neem oil if necessary. Proper watering practices will prevent root rot and other fungal issues.
