Philodendron Selloum (Hope) Not Growing: Light and Watering Fixes

Reader Question

My Philodendron bipinnatifidum 'Selloum Hope' in its original 12-inch pot was full when purchased. Now it's sparse, and new leaves (12–13 inches) quickly turn brown and die. Why isn't it growing?

Primary Suspects: Light and Water

Sparse, weak new growth usually signals insufficient light. Philodendron selloums need to be very close to an uncovered window but protected from >2–3 hours of direct sun (causes burning).

However, discolored/distorted new leaves indicate a root/watering issue. Since you haven't repotted, improper watering is likely.

Correct Watering Protocol

1. Wait until top ½ inch of soil feels dry.
2. Water slowly over entire surface until a trickle exits drain holes.
3. Don't water again until that dryness returns.

Critical Don'ts

• No repotting — it will worsen root stress.
• No fertilizer — it's not medicine and harms struggling plants.

Recovery Plan

Maximize bright indirect light + precise watering. Expect gradual improvement over weeks. Remove fully brown leaves — they won't recover.
