How To Grow Philodendron Split Leaf

Philodendron Split Leaf

Overview
Split Leaf Philodendron is a bold tropical foliage plant known for its enormous, deeply lobed green leaves and lush, architectural growth. Although commonly sold as a philodendron, this plant is botanically classified as Thaumatophyllum bipinnatifidum. Mature plants develop thick, trunk-like stems and can become impressive landscape specimens in warm climates.

Light Requirements
Prefers bright, indirect light to partial shade.
Outdoors, morning sun with afternoon shade is ideal in hot climates.
Avoid prolonged intense afternoon sun, which can scorch the foliage.

Temperature & Climate Fit
Thrives in warm, humid conditions.
Best growth occurs between 65–90°F.
Sensitive to frost and freezing temperatures. Established outdoor plants may recover from brief cold damage if the roots and growing points survive.

Watering
Moderate water needs.
Water thoroughly, then allow the upper 1–2 inches of soil to dry before watering again.
Avoid constantly saturated soil, which can lead to root rot.

Soil
Prefers rich, loose, well-draining soil.
For containers, use a quality tropical potting mix with added pine bark, perlite, or similar material to improve drainage and aeration.

Fertilizing
Feed with a balanced fertilizer during spring and summer while the plant is actively growing.
Reduce fertilization during cooler months when growth slows.

Maintenance
Remove yellow, damaged, or older leaves at the base as needed.
Mature plants develop thick stems and aerial roots.
Allow plenty of space for outdoor plants to develop their naturally broad form.

Pests & Problems
May occasionally develop spider mites, scale, or mealybugs.
Yellowing leaves can indicate excessive watering or poor drainage.
Brown leaf edges may result from drought stress, low humidity, or fertilizer salt buildup.

Works well beneath high tree canopies, near patios, in courtyards, and in tropical-style landscape beds.
