What is a Split Leaf Philodendron?

The term split leaf philodendron often causes confusion, as it’s used for several similarly dramatic leafy plants. True split leaf philodendrons belong to the Philodendron bipinnatifidum species, but the name is commonly (and incorrectly) applied to Monstera deliciosa as well. Both have large, fenestrated (split and perforated) leaves, but they differ in growth habit, origin, and care. For most houseplant enthusiasts, the differences aren’t as crucial as giving these lush plants the environment they need to thrive.

• Philodendron bipinnatifidum: Also called Tree Philodendron or Lacy Tree Philodendron. True split leaf philodendron, with deeply lobed leaves.
• Monstera deliciosa: Popular for its Swiss-cheese-like split and perforated foliage; often mislabeled as split leaf philodendron.

Plant Characteristics and Origins

Split leaf philodendrons are native to the rainforests of Central and South America. These plants are renowned for their robust, glossy green leaves with dramatic splits and lobes. They can grow impressively large indoors, bringing a lush, jungle-like aesthetic to any space.

• Growth Habit: Upright, bushy or tree-like with age.
• Leaf Size: Leaves can reach 3 feet or more in length in mature specimens.
• Life Span: Long-lived and forgiving with proper care.
• Height Indoors: Up to 6 feet or more with enough space.

Indoor vs Outdoor Growing

Split leaf philodendrons are adaptable, able to thrive both indoors and, in warm climates, outdoors. When grown outside, they make lush, bold landscape specimens. Indoors, they serve as showpiece houseplants.

• Outdoors: Suitable in USDA Zones 9–11. Protect from frost and extreme heat. Plant in filtered sun or dappled shade for best foliage.
• Indoors: Place in a bright room near a window, out of direct sunlight. Rotate for even growth and to prevent legginess.

Ideal Light and Location

Lighting is crucial for healthy, vibrant growth. Split leaf philodendrons prefer bright, indirect light but can tolerate some early morning sun—too much direct sunlight will scorch their leaves.

• Bright, indirect light is ideal. An east or south-facing window with sheer curtains works well.
• They can survive in lower light, but growth may slow and leaves can look sparse or smaller.
• Yellowing leaves may indicate excessive sunlight exposure.

Turn the plant periodically to encourage balanced leaf development and to prevent it from leaning towards the light source.

Watering and Humidity

Proper watering keeps your split leaf philodendron vigorous and resilient. Like most tropicals, it enjoys evenly moist—but not soggy—soil.

• Allow the top inch of soil to dry before watering again.
• Water thoroughly, letting excess drain away. Never let roots sit in water, as this causes rot.
• During spring and summer (active growing season), water more often. In fall and winter, reduce watering frequency.
• High humidity encourages luxuriant foliage. Mist the leaves regularly or use a humidifier nearby, especially in arid indoor climates.

Wilting and yellowing may signal overwatering, while crispy edges suggest underwatering or low humidity.

Soil and Potting Mix

Split leaf philodendron flourishes in loose, well-draining soil rich in organic matter. A quality aroid mix or standard indoor potting mix with added perlite, orchid bark, or compost is suitable.

• Repot every 1–2 years or when roots circle the pot bottom, preferably in spring.
• Choose a pot with drainage holes to avoid waterlogging.
• Amend the mix for extra drainage, especially in humid climates.

Fertilizing Your Split Leaf Philodendron

Lush new leaves demand nutrients. Feed your plant regularly during the growing season and sparingly otherwise.

• Use a balanced, water-soluble houseplant fertilizer (such as 20-20-20) every 4–6 weeks from spring through summer.
• Reduce fertilization in fall and winter, as growth naturally slows.
• Flush soil with plain water every few months to prevent salt buildup.

Pruning, Repotting & Propagation

Keeping your plant healthy and well-shaped is easy with a bit of routine care.

Pruning

• Remove yellowing, damaged, or old leaves at the base with sterile shears.
• Cut back leggy stems to encourage bushier growth.
• Prune to maintain size, especially in small spaces.

Repotting

• Repot every 1–2 years or when the plant outgrows its pot.
• Choose a container just one size larger.

Propagation

• Best propagated by stem cuttings. Use cuttings with a node and preferably an aerial root.
• Root in water or moist soil; transplant once roots are well formed.

Common Problems & Solutions

Regular inspection and prompt intervention keep your plant healthy and thriving.

Toxicity and Safety

Split leaf philodendrons, including both Philodendron bipinnatifidum and Monstera deliciosa, are toxic to pets and humans if ingested. All parts contain calcium oxalate crystals, which can cause oral irritation, vomiting, and swelling.

• Keep out of reach of cats, dogs, and small children.
• Wear gloves when pruning or propagating to prevent skin irritation.

Serious effects from casual contact are rare, but caution is advised.

Frequently Asked Questions (FAQs)

Q: Why are the leaves on my split leaf philodendron turning yellow?

A: Yellow leaves often indicate too much water or excessive sunlight. Let the soil dry slightly between waterings and avoid direct midday sun.

Q: Can split leaf philodendrons tolerate low light?

A: While they can survive in lower light, growth will be slower and may become leggy. Bright, indirect light is strongly recommended for vigorous growth.

Q: How often should I water my split leaf philodendron?

A: Water when the top inch of soil is dry to the touch. Adjust frequency for seasonal changes — more in summer, less in winter.

Q: Is split leaf philodendron the same as monstera?

A: No, but the names are often used interchangeably. True split leaf philodendron is Philodendron bipinnatifidum. Monstera deliciosa is a different but similarly leafy plant, often called Swiss Cheese Plant.

Q: What’s the easiest way to propagate a split leaf philodendron?

A: Take a stem cutting with at least one node and (if possible) an aerial root. Root in water or moist potting mix until established, then transplant to a larger container.

Final Thoughts

Split leaf philodendrons are forgiving, bold, and endlessly rewarding—making them perfect for beginners and experienced growers alike. By providing the right light, humidity, and the occasional pruning, these tropical giants will be a lush focal point for years to come. Remember to keep them out of reach of curious pets and children, and you’ll enjoy their vibrant greenery with minimal fuss. Happy gardening!
