Ring of Fire Philodendron is one of the most spectacular and rare philodendrons available to collectors and plant lovers. Its long, deeply serrated leaves display a fiery blend of orange, red, cream, and green variegation that changes with age and light exposure.
Ring Of Fire Philodendron Care
I love this plant because, despite its rarity, it isn’t too difficult to care for and keep. If you provide the right environment and a little patience, you will have a thriving houseplant.
In this guide, I will provide all the detailed information you need to grow, care for, and propagate this stunning hybrid.
Understanding the Ring of Fire Philodendron
Hybrid Background
Philodendron ‘Ring of Fire’ is believed to be a hybrid between Philodendron wendlandii and Philodendron tortum. This mix gives it its distinctive serrated leaf margins and striking color patterns.
Growth Habit
This is a slow-growing, upright philodendron that develops a bushy structure over time. With adequate light and nutrients, it can reach up to 4 feet in height and width indoors.
Leaf Characteristics
Its most iconic trait is its long, jagged, saw-tooth leaves. New growth often emerges in shades of copper, orange, or even pink and slowly matures to include greens and creams. Each leaf is unique in color, creating a dynamic and ever-changing visual appeal.
Rarity and Cost
Due to its slow growth rate and propagation difficulty, ‘Ring of Fire’ is considered a rare and sometimes expensive plant, especially in mature sizes or with high variegation.
Light Requirements
Ideal Light: Bright, indirect light is essential for encouraging vibrant variegation and healthy growth. Place the plant near a bright window but shield it from direct rays, which can damage the lighter-colored leaf sections.
Too Much Light: Exposure to strong, direct sunlight can bleach the leaves, turning the white or cream sections yellow or brown and causing irreversible sunburn.
Too Little Light: In low light, the plant’s colors will become muted, and growth will slow. The leaves may revert to more green tones, losing their characteristic variegation.
Solutions for Low Light: Consider using a full-spectrum grow light if natural light is insufficient, especially in winter months.
Temperature and Humidity
Aim to keep your Philodendron ‘Ring of Fire’ between 65–85°F (18–29°C) at all times. These temperatures mimic the tropical habitats the plant is adapted to.
The plant is not frost-tolerant and will suffer damage below 55°F (13°C). Cold air can cause leaf curling, blackened edges, and even plant death.
High humidity (60% or more) is ideal. While it can survive in moderate household humidity, low humidity can cause leaf tips to brown and limit variegation.
Use a room humidifier, place the plant on a humidity tray filled with water and pebbles, or cluster it with other tropical plants to create a more humid microclimate.
Soil Requirements
The plant prefers a fast-draining, chunky mix that prevents root rot and mimics the loose, organic matter found in the rainforest floor.
Philodendron Soil Mix recipe:
- 40% Orchid Bark or Pine Bark Fines – Adds texture and prevents compaction
- 25% Coco Coir or Peat Moss – Retains moisture without becoming soggy
- 20% Perlite or Pumice – Enhances drainage and aeration
- 10% Activated Charcoal – Absorbs toxins and improves soil health
- 5% Worm Castings or Compost – Supplies organic nutrients for steady growth
Aim for a slightly acidic to neutral pH (5.5 to 7.0) to ensure proper nutrient absorption.
Watering Routine
Water thoroughly when the top 2–3 inches of soil feel dry to the touch. This typically means every 7–10 days during spring and summer and less frequently in winter.
Avoid overwatering, as it is one of the most common issues with philodendrons. Soggy soil leads to root rot, indicated by mushy roots, foul odors, or blackened stems.
You should also avoid underwatering. If the soil remains dry for too long, the plant may wilt, develop dry or curling leaves, and halt growth.
Watering Tips:
- Use filtered or distilled water to avoid mineral buildup.
- Water deeply until it drains from the bottom of the pot, then allow the soil to dry partially before the next watering.
- Avoid letting the pot sit in standing water.
Fertilizing Your Philodendron
Start feeding in early spring and continue through summer. Pause or reduce frequency during fall and winter when the plant’s growth slows.
Use a balanced liquid fertilizer (such as 20-20-20 or 10-10-10) monthly or a slow-release granular fertilizer every 2–3 months.
Look for formulas that include magnesium, calcium, and iron, which help maintain healthy variegation and chlorophyll production.
Always dilute fertilizers to half strength and apply to moist soil to reduce the risk of root burn.
Potting and Repotting
Repot every 1–2 years or when the plant becomes rootbound. Signs include slowed growth, roots emerging from the drainage holes, or water running straight through the pot.
Choose a pot that is only 1–2 inches larger in diameter to avoid excess soil holding too much water.
Repotting Steps:
- Water the plant the day before to reduce stress.
- Gently remove the plant and examine the root system.
- Trim away any black, mushy, or dead roots with sterilized scissors.
- Add fresh soil to the base of the new pot.
- Center the plant and fill in with your aroid mix.
- Water thoroughly and place in indirect light for recovery.
Pruning and Maintenance
Regularly remove any yellow, dry, or damaged leaves to conserve the plant’s energy and improve airflow.
Prune leggy stems to encourage bushier growth and a more compact shape. Wipe leaves with a soft, damp cloth every few weeks to remove dust that can block light absorption.
As the plant matures, it may benefit from a moss pole or stake to support upright growth and mimic climbing behavior.
Common Problems and Solutions
Pests
Spider Mites: Tiny webbing and speckled leaves indicate infestation. Treat with neem oil or insecticidal soap.
Mealybugs: Cotton-like clusters on leaf joints. Remove with rubbing alcohol and cotton swabs.
Scale: Hard, shell-like insects. Gently scrape off and apply horticultural oil.
Prevention Tips: Quarantine new plants, inspect regularly, and maintain high humidity.
Diseases
Root Rot: Caused by consistently wet soil. Trim rotting roots, treat with fungicide, and repot in fresh soil.
Leaf Spot: Yellow or brown lesions from fungal pathogens. Improve airflow and avoid wetting leaves.
Environmental Stress
- Brown Edges: Often due to low humidity or excess fertilizer salts.
- Curling Leaves: May indicate underwatering or cold drafts.
- Color Fading: If variegation fades, increase light and ensure proper nutrients are provided.
Propagation Methods
1. Stem Cuttings
The best time for stem cutting propagation is Spring or early summer when the plant is actively growing.
Steps:
- Choose a healthy stem with 1–2 nodes and aerial roots if possible.
- Cut below the node using sterilized pruning shears.
- Remove lower leaves to expose the node.
- Place in water or moist soil, ensuring the node is submerged or buried.
- Cover with a humidity dome or plastic bag to retain moisture.
- Roots usually form in 3–6 weeks.
Transplant once the roots are 2–3 inches long, transfer the cutting to a pot with your standard soil mix.
2. Air Layering
Air layering is advantageous in that it allows roots to form while the cutting is still attached to the mother plant.
Steps:
- Select a healthy node and wrap it in moist sphagnum moss.
- Enclose with plastic wrap and secure with twist ties or string.
- Keep the moss moist and check for root growth in 4–8 weeks.
- Once roots are visible, cut below the rooted node and pot as usual.
Toxicity and Safety
The ring of fire philodendron contains toxic components. It contains calcium oxalate crystals that cause irritation if ingested.
If ingested by pets, the common symptoms include drooling, oral swelling, vomiting, and difficulty swallowing.
Keep your plant out of reach of pets and children. Also, always wear gloves when handling or pruning to prevent skin irritation.
Ring Of Fire Philodendron Display and Styling Tips
Container Styling: Use modern ceramic or terracotta pots that contrast with the variegation.
Placement Ideas:
- On shelves or plant stands with ample indirect light
- On a moss pole to create a vertical focal point
- In large floor pots surrounded by other tropicals for a jungle aesthetic
Companion Plants: Pair with Monstera deliciosa, Calathea orbifolia, or Alocasia Polly for a lush, diverse plant collection.
