How to Grow, Plant, and Care for Split Leaf Philodendron

Split leaf philodendrons, prized for their dramatically lobed leaves and lush, tropical vibe, have become a staple in homes and offices worldwide. Whether you know them as Monstera deliciosa or Philodendron selloum (now classified as Thaumatophyllum bipinnatifidum), these striking houseplants stand out for their rapid growth and captivating foliage. In this detailed guide, you’ll discover everything you need to cultivate healthy split leaf philodendrons indoors or out, from lighting and soil choice to propagation and pest management.

What Is a Split Leaf Philodendron?

The split leaf philodendron, often confused with Monstera due to its deeply cut, fenestrated leaves, belongs to the family Araceae. In the wild, these tropical plants can climb trees with their aerial roots, producing enormous leaves that split as they mature. Indoors, they provide striking greenery and can become impressive focal points if given space and care.

• Common Names: Split leaf philodendron, Monstera, Philodendron selloum
• Botanical Classification: Monstera deliciosa or Thaumatophyllum bipinnatifidum
• Native Region: Tropical rainforests of Central and South America
• Plant Features: Large, deeply divided leaves; aerial roots

Split Leaf Philodendron Basics

These plants offer not just visual appeal but air-purifying qualities as well. While their care requirements are relatively straightforward, mastering a few details will ensure your philodendron remains vibrant for years.

• Growth Habit: Upright with sprawling, broad leaves
• Typical Size Indoors: 3–6 feet tall and wide
• Lifespan: Can thrive for decades with proper care
• Flowering: Rare indoors; decorative white spadix and spathe outdoors under ideal conditions

Choosing the Right Location

The secret to a thriving split leaf philodendron is providing the right balance of light, warmth, and humidity. Choose a spot where it can stretch out comfortably, especially as its leaves reach their mature size.

• Keep away from direct sun, which can scorch leaves
• Place near an east or south-facing window with filtered light
• Avoid cold drafts or dry, hot air from vents

Light Requirements

Split leaf philodendrons revel in bright, indirect sunlight. Lighting conditions shape their growth and leaf size:

• Bright, indirect light yields lush, robust leaves
• Some morning direct sun is tolerated, but strong afternoon rays can cause yellowing or browning
• In lower light, growth will slow and leaves may become smaller or sparser
• Rotate the pot regularly for even growth

Soil Preferences

Healthy roots are the foundation of a vibrant philodendron. Your soil mix should hold moisture but drain freely to prevent rot.

• Use a light, well-draining potting mix; most commercial houseplant blends suffice
• For DIY mixes, combine:
  • 2 parts potting soil
  • 1 part perlite (for drainage and aeration)
  • 1 part coconut coir (for moisture retention without heaviness)
• Optionally, add bark chips or horticultural charcoal for extra drainage, especially in large pots
• In lower light, add extra perlite or bark to prevent sogginess

Watering and Humidity

Watering is a balancing act—too much leads to root rot, too little to drooping and brown tips. Monitor the top inch of soil and adapt to your environment’s humidity and the season.

• Let the top 1–2 inches of soil dry between waterings
• Water thoroughly until it drains from the pot’s base, then empty any saucer
• Decrease frequency in fall and winter when growth slows
• Misting is optional but can boost humidity, especially during dry spells
• Ideal humidity: 50–60%, though the plant can adapt to normal household levels

Feeding and Fertilization

Your split leaf philodendron will appreciate a steady supply of nutrients:

• Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength
• Pause or reduce feeding in fall and winter
• Occasionally flush soil to prevent mineral buildup

Repotting

Expect rapid root growth from a healthy split leaf philodendron. Repot every 1–2 years or when roots fill the container:

• Choose a pot 2 inches wider than the current one
• Refresh soil at each repotting to maintain drainage
• Repotting is best done in spring
• Loosen and trim encircling roots before transplanting

Pruning and Maintenance

Routine pruning encourages new growth and helps control the plant’s size and shape.

• Remove yellow, damaged, or old leaves at the base with sterile scissors
• Cut back leggy stems to promote bushier growth
• Always wear gloves—sap can irritate skin

Propagation

Split leaf philodendrons are easy to propagate from stem cuttings:

1. Choose a healthy stem with at least one leaf and an aerial root
2. Cut below a node with clean, sharp scissors
3. Remove lower leaves; place the cutting in water or moist soil
4. Keep in bright, indirect light and refresh water weekly if propagating hydroponically
5. Transplant to soil once roots are 2–4 inches long

Common Problems and Solutions

Pests and Diseases

Split leaf philodendrons are resilient but can occasionally suffer from common houseplant pests:

• Spider Mites: Look for fine webbing and tiny moving dots
• Mealybugs: White, cottony masses on leaves/joints
• Aphids: Clusters of green or black insects on new growth
• Treat infestations early with a soap and water spray or neem oil
• Isolate and prune affected areas if needed
• Wipe leaves regularly with a damp cloth to deter pests

Toxicity Warning

All parts of the split leaf philodendron contain calcium oxalate crystals, which are toxic to pets and mildly toxic to humans if ingested. Symptoms include swelling, irritation, vomiting, and difficulty swallowing. Always keep the plant out of reach of small children and curious animals, and wear gloves when handling or pruning.

Styling and Display Ideas

Let your split leaf philodendron shine with these indoor decor tips:

• Give it pride of place as a living sculpture in large rooms
• Pair with minimalist pots to emphasize dramatic leaves
• Use as a statement plant in entryways or office corners
• Allow aerial roots to dangle or guide them into moss poles for vertical displays

Frequently Asked Questions (FAQs)

Q: What is the difference between Monstera deliciosa and split leaf philodendron?

While often confused due to similar foliage, Monstera deliciosa (commonly called split leaf philodendron) is its own species. True philodendrons such as Philodendron selloum (now Thaumatophyllum bipinnatifidum) have similarly split leaves but a different growth habit. Both require similar care indoors.

Q: Can split leaf philodendron survive low light?

They tolerate low light but grow best in bright, indirect sunlight. In low light, growth slows and foliage may become sparse or leggy.

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

Generally, wait until the top inch or two of soil feels dry, then water thoroughly. Adjust frequency based on humidity, pot size, and season.

Q: Why are my philodendron’s leaves turning yellow?

Yellow leaves are often caused by overwatering or exposure to direct sun. Let the soil dry more between waterings and move the plant if needed.

Q: Is split leaf philodendron safe for pets?

No. All parts are toxic to cats, dogs, and people if ingested. Keep out of reach and seek veterinary care if your pet chews any part of the plant.

Q: How do I make my split leaf philodendron bushier?

Prune leggy stems and provide bright, indirect light for fuller, denser foliage. Regular feeding and occasional repotting also help.

Conclusion

Split leaf philodendrons offer bold greenery and an unmistakable tropical feel to any indoor space. With the right blend of light, soil, water, and attention, these resilient plants will reward you with years of dramatic, healthy growth. Follow the advice in this guide for robust, thriving philodendrons—whether you’re a plant novice or an indoor jungle enthusiast!
