Brown Leaf Tips
What This Symptom May Mean
Brown, crispy tips on leaves typically indicate that the plant is losing moisture faster than it can absorb it, or that dissolved salts have accumulated in the soil. This is especially common in tropical plants that prefer higher humidity levels. While the browned tips will not recover, correcting the underlying cause will prevent further damage.
Common Causes
- 1Low humidity, especially in heated or air-conditioned indoor environments
- 2Inconsistent watering causing periodic dehydration at the leaf margins
- 3Excess fluoride or chlorine in tap water damaging sensitive tissue
- 4Salt and mineral buildup in the soil from fertilizer or hard water
- 5Overfertilization burning the leaf tips
How to Check
- ✓Measure indoor humidity with a hygrometer — many tropicals need 50% or higher
- ✓Check if you are using unfiltered tap water that may contain fluoride or chlorine
- ✓Look for white crust on the soil surface, which indicates mineral buildup
- ✓Review your fertilizing schedule and concentration
- ✓Assess whether the plant is near a heating vent, radiator, or drafty window
What to Try First
- →Increase humidity by grouping plants together, using a pebble tray, or running a humidifier
- →Switch to filtered, distilled, or rainwater for sensitive species
- →Flush the soil thoroughly every few months by running water through it for several minutes
- →Reduce fertilizer concentration to one-quarter or one-half strength
- →Trim browned tips with clean scissors at an angle for a natural look
- →Move the plant away from direct heat sources and cold drafts

Overwatering
Overwatering is the single most common cause of houseplant death. It occurs not just from giving too much water at once, but more often from watering too frequently before the soil has had a chance to dry out appropriately.
Humidity for Houseplants
Humidity refers to the amount of water vapor present in the air surrounding a plant. Many popular houseplants hail from tropical rainforests where relative humidity regularly exceeds sixty percent, making indoor humidity management an important aspect of their care.
Fertilizing Houseplants
Fertilizing provides houseplants with essential macro- and micronutrients that are gradually depleted from potting soil over time. Unlike outdoor plants that benefit from natural nutrient cycling, container plants rely entirely on their grower to replenish these nutrients.
