33-Year-Old Philodendron Selloum: Water and Fertilizer Needed

Diagnosis

Brown leaves, north window, watering every 2 weeks = underwatering and nutrient deficiency. Philodendron selloum uses water quickly.

Fix

• Water more frequently — when top inch dry (summer: every other day; winter: weekly).
• Apply balanced fertilizer (e.g., 20-20-20 at half strength).
• Monitor for perk-up.

Light Note

North window is low light but acceptable. It's survived 33 years there. Don't move it now.
