Philodendron Recurring Leaf Disease: Cultural Care Review

35-year-old philodendron gets "chewed" spots on leaves every 6 weeks; spots expand rapidly. Early trimming saves leaf. Cat suspected but not confirmed.

General Philodendron Needs

• Medium light (jungle floor); low light → small leaves; direct sun → burn.
• Even moisture, dry between waterings; drier in winter.
• Overwater → yellow leaves; underwater → brown drop.
• Fertilize spring & mid-summer with liquid houseplant food.
• Ideal temp: 75-85°F day, 60s night; survives to 36°F briefly.
• Mist for humidity; wash leaves to prevent dust clogging pores.
