Sansevieria Problems: Causes and Solutions
Yellow Leaves
Yellow leaves on Sansevieria are often caused by overwatering. The roots of snake plants are sensitive to excess moisture and may rot if the soil stays wet for too long. Other possible causes include insufficient light, sudden temperature drops, or natural ageing of older leaves. Check the soil before watering and only water when the top 3–5 cm feels dry. Remove yellow leaves if they are soft or mushy, as this may indicate rot.
Root Rot and Soggy Soil
Root rot is a common issue if Sansevieria sits in waterlogged soil. Signs include soft, mushy stems at the base, a foul smell, and leaves collapsing. To check, gently remove the plant from its pot and inspect the roots: healthy roots are firm and white or light orange, while rotten roots are brown and mushy. Cut away affected roots with clean scissors and repot in fresh, well-draining soil. Avoid watering for at least a week after repotting.
Brown Spots and Dry Edges
Brown spots or crispy edges can result from underwatering, low humidity, or sunburn. Sansevieria tolerates dry air but may develop dry tips if left too long without water. If brown spots appear suddenly, check for pests or fungal issues. Avoid placing the plant in direct midday sun, especially in summer. Trim dry or damaged leaf parts with clean scissors if desired.
Stunted Growth
If your Sansevieria stops growing, it may be due to low light, cold temperatures, or lack of nutrients. Growth naturally slows in winter. Ensure the plant receives bright, indirect light and is kept above 15°C. Repotting every few years and refreshing the soil can also help.
Common Care Mistakes
- Watering too frequently or letting the pot stand in water.
- Using pots without drainage holes.
- Placing the plant in dark corners for extended periods.
- Sudden exposure to strong sunlight after being in shade.
When to Seek Help
If your Sansevieria continues to decline despite adjusting care, or if you notice widespread rot or pest infestations, consider consulting a local plant expert or nursery. Severe root rot may not be reversible.
Frequently Asked Questions
- Why does my Sansevieria have yellow leaves?
- Yellow leaves are usually caused by overwatering or poor drainage. Always check if the soil is dry before watering. Remove yellow, soft leaves to prevent rot from spreading.
- How can I recognise root rot in Sansevieria?
- Root rot is indicated by soft, mushy stems at the base, a musty smell, and brown, mushy roots. Healthy roots are firm and pale. If you suspect rot, remove the plant from its pot and inspect the roots.
- What should I do about brown spots on Sansevieria leaves?
- Brown spots can result from underwatering, sunburn, or pests. Check for pests and avoid direct midday sun. Trim damaged areas if needed and adjust watering habits.
