Philodendron Selloum (Tree Philodendron): Light, Water, and Fertilizer Fixes

Correct ID

Your plant is Philodendron bipinnatifidum (selloum), not Monstera deliciosa. Care is similar but distinct.

Location Is Fine

East window with 1 hour direct sun + grow light in winter is near ideal. No need to move outdoors.

Natural Aging

Older leaves droop and die as new growth emerges on top—creating a tree-like trunk. Rotate for straight growth. Tall trunks can be cut back if needed.

Change Watering Routine

• Allow top 1–2 inches to dry thoroughly.
• Water until trickle from drain holes.
• Wait until top 1–2 inches dry again.
• Fertilize monthly at half-strength.

Your 20-year-old plant will thrive with these adjustments.
