Brown tips on herbaceous plants are common and usually indicate that the plant is under some kind of stress. The cause is not always the same, but these are the most frequent reasons:
- Low humidity
- Dry indoor air or hot conditions can cause leaf edges and tips to turn brown, especially in tropical plants.
- Incorrect watering
- Too little water: Leaves dry out and develop crispy brown tips.
- Too much water: Roots may become damaged and unable to supply the leaves properly.
- Salt or fertilizer buildup
- Excess fertilizer or minerals from hard tap water can accumulate in the soil and burn leaf tips.
- Poor drainage
- Waterlogged soil reduces oxygen around the roots and can lead to leaf browning.
- Too much direct sunlight
- Leaves can scorch when exposed to intense sunlight, especially if the plant prefers shade or indirect light.
- Temperature stress
- Cold drafts, heat from radiators, or sudden temperature changes can damage leaf tips.
- Natural aging or damaged leaves
- Older leaves may gradually develop brown areas as the plant redirects energy to new growth.
What you can try:
- Check the soil moisture before watering.
- Ensure the pot has drainage holes.
- Move the plant away from harsh direct sun or drafts.
- Increase humidity if the air is dry.
- Reduce fertilizer use and occasionally flush the soil with clean water.
If you tell me the plant name, whether it is indoors or outdoors, and how often you water it, I can help narrow down the likely cause.
