Diagnosing Brown Leaf Tips on Unknown Houseplants

Identification First

Brown, crispy leaf tips and spots have many causes: improper light, watering issues, poor water quality (fluoride, salts), root damage, temperature extremes, or pathogens. Without knowing the plant species, any advice is guesswork.

What I Need to Help You

• Photos: Clear images of the whole plant, leaf close-ups, and the base/stems. Email to wcreed@HorticulturalHelp.com.
• Light conditions: Window direction, distance from window, hours of direct sun, any obstructions.
• Watering routine: Frequency, amount, whether you use tap, filtered, or distilled water.
• Pot and soil history: When last repotted? What potting mix? Does the pot have drainage holes?

Common Culprits for Tip Burn

• Fluoride/chloride in tap water: Especially affects Dracaena, Spider Plant, Peace Lily, and Maranta. Switch to rain, distilled, or filtered water.
• Inconsistent watering: Alternating bone-dry and soggy soil damages roots.
• Low humidity: Thin-leaved tropicals suffer in dry heated air.
• Over-fertilization: Salt buildup burns leaf margins.

Once I see the plant, I can pinpoint the issue and give targeted care instructions.
