Philodendron Gigas – Rare Plant

Philodendron Gigas is a spectacular climbing aroid admired for its enormous, velvety, deep-green leaves that develop bronze and copper undertones as they mature. Native to the rainforests of Panama, this plant grows up tall trees, producing massive foliage that can reach impressive sizes in ideal conditions. Because of its luxurious texture, rapid growth, and rarity, Philodendron Gigas is considered a prized collectible for aroid lovers. With the right environment, it grows vigorously and becomes a true statement piece in any indoor or shaded outdoor space. Here is a complete care guide to help your Philodendron Gigas thrive.

Philodendron Gigas – Rare Plant Care Guide:

Light Requirements

Philodendron Gigas prefers bright, indirect light. In the wild, it grows under the canopy of large trees, receiving dappled sunlight. Indoors, place it near a bright window with filtered light. Avoid harsh afternoon sun as it can burn the delicate velvety leaves and fade their bronze tones. If natural light is insufficient, use a grow light for 6–8 hours daily. Proper lighting encourages larger leaves, faster climbing, and deeper coloration.

Temperature

This tropical species thrives in warm climates. The ideal temperature range is 20–30°C. It does not tolerate cold conditions below 15°C. Avoid placing the plant near cold drafts, air conditioners, or direct heat from appliances. Consistent temperatures help maintain steady growth and prevent leaf damage or root stress. If grown outdoors in tropical regions, keep it in deep shade or filtered sunlight.

Humidity

Humidity is a key factor for healthy Philodendron Gigas growth. Aim for 60–90% humidity. High humidity enhances leaf size, velvet texture, and overall appearance. To maintain ideal humidity indoors, you can:

• Use a cool-mist humidifier

• Keep a pebble tray under the pot

• Place the plant in a greenhouse cabinet

• Group it with other humidity-loving plants

Misting is optional but avoid excessive moisture on leaves, as it can encourage fungal issues.

Watering

Philodendron Gigas prefers evenly moist soil, but not waterlogged conditions. Water when the top 2–3 cm of soil feels dry. Overwatering leads to yellowing leaves and root rot, while underwatering causes droopy or curled leaves. During the active growing season (March–October), water more frequently. In winter, reduce watering slightly but never allow the plant to dry out completely. Always ensure the pot has drainage holes and discard standing water after each watering.

Soil Mix

A well-aerated, chunky soil mix is essential. Gigas has thick roots that need good airflow. Use the following mix:

• 40% cocopeat or peat moss

• 30% perlite or pumice

• 20% orchid bark

• 10% activated charcoal or compost

This combination mimics its natural habitat and prevents root rot by ensuring fast drainage while retaining enough moisture.

Fertilization

Feed Philodendron Gigas every 2–3 weeks during the growing season with a balanced liquid fertilizer (such as 20-20-20). Dilute it to half strength to avoid root burn. Slow-release fertilizer granules can be added every 3–4 months. Avoid fertilizing heavily during winter when growth naturally slows down.

Support & Growth Pattern

Philodendron Gigas is a true climber. To unlock its full growth potential, provide a moss pole or coco pole. As the plant climbs, it produces increasingly larger leaves with more bronze and velvety tones. Tie the stems gently to the pole to guide upward growth. Without support, it will trail and produce smaller leaves.

Repotting

Repot the plant every 1–2 years, preferably at the start of the growing season. Choose a pot just one size larger. Oversized pots retain excess moisture, increasing the risk of rot. During repotting, check for damaged or decaying roots and trim them cleanly.

Pest and Disease Control

Common pests include:

• Spider mites

• Mealybugs

• Aphids

• Fungus gnats

Treat infestations with neem oil or insecticidal soap. Ensure good airflow to prevent fungal infections. Avoid water sitting on the leaves for too long, as velvety surfaces can develop spots if moisture remains trapped.

Propagation

Philodendron Gigas can be easily propagated through stem cuttings. Select a healthy segment with at least one node and an aerial root. Root cuttings in moist moss, water, or a well-aerated soil blend. Maintain high humidity for faster rooting.

Conclusion

Philodendron Gigas is a rare tropical gem that rewards growers with dramatic, velvety foliage and fast climbing growth. With proper care—bright indirect light, high humidity, warm temperatures, and an airy soil mix—it grows into a breathtaking display plant. Whether you’re a beginner or a seasoned collector, this luxurious aroid is a standout addition to any plant collection.
