Snake plants are known for being low-maintenance and tough, making them a great choice for busy people or beginner plant lovers. But even this strong plant can face issues sometimes. One common problem is when the leaves start to rot — they may turn soft, brown, or fall over.
So, what’s causing this? Let’s look at the main reasons behind snake plant leaf rot and how you can fix and prevent it.
1. Overwatering – A Common Mistake
Snake plants don’t need much water. In fact, giving them too much water is one of the biggest mistakes people make. These plants store water in their thick leaves, so they don’t like wet soil.
How to Spot Overwatering:
- Leaves feel squishy or soft
- Yellow or brown patches appear
- Soil stays wet for a long time
- You may notice a bad smell from the pot
What to Do:
Let the soil dry out before you water again. Use your finger to check if the top 2 inches of soil are dry. If the soil is still moist, wait a few more days. Water only when the plant really needs it—usually every 2 to 3 weeks, depending on the weather.
2. Soil That Holds Too Much Water
Even if you’re not watering too often, the wrong kind of soil can still cause problems. Some soil mixes keep too much moisture, which can lead to root and leaf rot.
Signs of Poor Drainage:
- Water sits on top of the soil
- The bottom of the pot is always damp
- Leaves look unhealthy even with proper watering
Solution:
Use a potting mix made for succulents or cactus plants. You can also mix in sand or perlite to help the water drain faster. Always plant your snake plant in a pot with holes at the bottom to let excess water escape.
3. Rotting Roots
If the roots of your snake plant are sitting in soggy soil for too long, they may start to rot. Rotten roots can’t support the plant, which leads to drooping or damaged leaves.
Warning Signs:
- Roots are black or brown and feel mushy
- Leaves are falling over or turning soft
- You smell something sour or unpleasant near the plant
What to Do:
Take the plant out of its pot. Cut off the soft or dark roots with clean scissors. Let the healthy parts dry for a few hours. Then repot your plant in new dry soil and a clean pot with drainage.
4. Cold Weather Damage
Snake plants prefer warm spaces. If they are placed in a cold spot, especially near windows in winter, they can suffer. Cold can harm the leaves, making them rot or fall over.
What Happens in Cold Temperatures:
- Leaves get soft and weak
- Dark spots appear on the surface
- The whole plant may stop growing
What to Do:
Keep your snake plant in a room with a temperature above 50°F (10°C). Avoid placing it near air conditioners, open windows, or cold drafts.
5. Too Much Humidity
Snake plants like dry air more than moist air. If the air around your plant is too humid, it can lead to mold or fungal infections, especially on the leaves or in the soil.
What to Watch For:
- Sticky or wet leaves
- White fuzzy growth on the soil or plant
- Leaves becoming slimy or soft
Prevention Tips:
- Don’t spray water on the leaves.
- Place the plant in a room with good airflow.
- Use a small fan or dehumidifier if the space feels damp.
6. Bugs and Fungal Infections
Sometimes, insects or fungus can attack your snake plant, especially if the plant is already weak or the soil is too wet.
Common Pests:
- Fungus gnats
- Mealybugs
- Spider mites
How to Fix It:
Check the plant carefully, including the bottom of the leaves. If you see bugs or mold, wipe them off and treat the plant with neem oil or insecticidal soap. Remove any rotting leaves and keep the plant away from others while it heals.
How to Prevent Rot in Snake Plants
To avoid leaf rot and keep your snake plant happy, follow these simple care tips:
- Water less often – only when the top part of the soil is dry
- Use a pot with holes to let water drain easily
- Pick the right soil – light and fast-draining
- Keep it warm – don’t let your plant get cold
- Don’t mist the leaves – snake plants don’t like too much moisture
- Check regularly – early signs are easier to fix
Final Thoughts
Rotting leaves are a sign that your snake plant is under stress, usually from too much water or poor drainage. Luckily, this issue can be fixed with a little care and attention. By adjusting your watering habits, improving drainage, and watching the temperature and humidity, you can help your snake plant recover and stay healthy.
With the right care, your snake plant will thrive and continue to brighten up your home for years to come.
