Noticing brown edges or spots on your houseplant's leaves can be worrying, but it's a common issue that usually has a clear explanation. Below you'll find the most frequent causes and what you can do to help your plant recover.

Why Do Leaves Turn Brown?

Brown leaves or edges can result from several factors, often related to the plant's environment or care. The most common reasons include dry air, inconsistent watering, root problems, sunburn, or issues with fertilizer. It's rarely a sign of a fatal problem, but it's a good idea to check your plant's conditions.

Dry Air or Draft

Indoor air can become very dry, especially in winter when heating is on. Many houseplants prefer higher humidity. Dry air can cause leaf tips or edges to turn brown and crispy. Drafts from windows or doors can also stress plants, leading to similar symptoms.

Underwatering or Root Problems

If the soil dries out too much between waterings, leaves may develop brown spots or edges. On the other hand, if roots are damaged by overwatering or compacted soil, the plant may struggle to take up water, causing similar symptoms. Always check the soil before watering: it should be slightly dry at the top, but not bone dry or soggy.

Sunburn or Fertilizer Issues

Direct sunlight, especially through glass, can scorch leaves and cause brown patches. Over-fertilizing can also burn roots and leaf edges. If you recently moved your plant to a sunnier spot or added fertilizer, this could be the cause.

What Can You Do?

• Check humidity: If the air is dry, try grouping plants together or moving them away from radiators and drafts. Read more about humidity.
• Water carefully: Let the top layer of soil dry out before watering again. Avoid letting the plant sit in water. Watering tips.
• Review placement: Keep plants out of direct midday sun and away from cold drafts or hot radiators. More about placement.
• Trim damaged leaves: You can carefully cut off brown tips or remove badly affected leaves. This won't harm the plant.
• Check for root issues: If browning continues, consider checking the roots for rot or compacted soil. Repotting advice.

Frequently Asked Questions

Should I cut off brown leaves?

Yes, you can trim brown tips or remove fully brown leaves. Use clean scissors and cut just above a healthy part of the leaf or stem. This helps the plant focus energy on healthy growth.

Can dry air cause brown leaf edges?

Yes, dry indoor air is a common cause of brown edges, especially in winter. Increasing humidity or moving your plant away from radiators can help prevent this.

Does repotting help with brown leaves?

Repotting can help if the browning is due to root problems or compacted soil. If roots are healthy and the soil drains well, repotting is not always necessary.
