Snake Plant Problems: 10 Common Issues & How to Fix Them
Find out how to identify and treat snake plant problems such as drooping, stunted growth, and pest infestations for a thriving plant.
What are the most common snake plant problems?
Yellowing leaves, mushy roots, brown tips, curling foliage, stunted growth, and pest infestations are the top snake plant issues. These are usually caused by overwatering, poor lighting, low humidity, nutrient deficiencies, or pests. Fixing them involves adjusting watering habits, improving drainage, boosting humidity, fertilizing mindfully, and treating pests early.
Snake plants (Dracaena trifasciata, formerly Sansevieria) are celebrated for their resilience, but even these hardy houseplants can run into trouble when their environment isn’t quite right. Understanding how environmental factors like light exposure, temperature fluctuations, and humidity levels interact with plant health is crucial for both prevention and recovery.
As plant enthusiasts and science-driven growers, we’ve seen firsthand how subtle changes in your snake plant’s microclimate can trigger issues—from yellowing leaves to mushy roots. In this guide, you’ll learn not only how to diagnose and fix the most common snake plant problems, but also how to optimize your plant’s environment for long-term health.
But before exploring environmental factors in detail, it’s essential to understand how soil, pot and watering directly impact root health—the foundation of a thriving snake plant. If you’re curious about all the benefits snake plants bring to your home—beyond their resilience to common issues—see our guide: What Does a Snake Plant Do for Your House? (10 Amazing Benefits).
Soil, Pot, Watering, and Root Health: The Core of Snake Plant Health
The foundation of a thriving snake plant lies in the synergy between soil, pot, and watering practices. Poor soil or pot choices trap excess moisture and suffocate roots, while the wrong watering routine can quickly lead to root rot or dehydration.
Essentials:
- Soil: Use a fast-draining succulent or cactus mix, boosted with perlite or coarse sand. Avoid heavy, moisture-retentive soils.
- Pot: Always choose pots with drainage holes. Terracotta is ideal for its breathability and moisture control. Select a pot just slightly larger than the root ball.
- Watering: Only water the plant when the top 2–3 inches of soil are dry. Water until it drains out, but do not leave the plant sitting in extra water.
Key Signs to Watch:
| Issue | Common Cause |
| Mushy, brown roots | Overwatering, poor drainage |
| Brittle, dry roots | Underwatering, overly fast-drying soil |
| Stunted growth | Compacted soil, pot-bound roots |
Pro Tip:
Check roots and soil first when problems arise. Healthy roots are firm and pale; mushy or dry roots signal a need to repot and adjust your care.
By focusing on well-draining soil, breathable pots, and responsive watering, you’ll prevent most snake plant problems at the source. For a complete overview of ideal watering, soil, and light practices, check out our full care guide: How to Care for Snake Plants.
The Impact of Environmental Factors on Snake Plant Health
Before diving into specific problems, it’s important to recognize that many snake plant issues originate from environmental stress. Light, temperature changes, and humidity are all very important for your plant’s health.
Light Exposure: Snake plants tolerate a wide range of light, but thrive best in bright, indirect sunlight. Too little light can cause pale, stretched leaves (etiolation), while too much direct sun can lead to leaf scorch and brown tips.
Temperature Fluctuations: Sudden drops below 50°F (10°C) or spikes above 85°F (29°C) can shock snake plants, resulting in yellowing, wrinkling, or stunted growth. Consistent temperatures are key—aim for a stable range between 60–80°F (16–27°C).
Humidity Levels: While snake plants are adapted to moderate humidity (30–50%), extremely dry air can lead to crispy brown tips, and persistently high humidity—especially without good airflow—can promote rot and fungal issues.
In our experience, many “mystery” symptoms resolve quickly once environmental stressors are addressed. Monitoring your plant’s microclimate and making small adjustments often prevents larger problems down the line.
1. Yellowing Leaves
Symptoms: Leaves turn pale yellow, then brown, often starting at the base.
Environmental Triggers:
- Overwatering combined with low light or cold temperatures
- Prolonged exposure to drafts or sudden temperature drops
How to Fix:
- Place the plant where it gets plenty of light, but not direct sunlight.
- Keep the temperature above 50°F (10°C) and away from cold air.
- Let soil dry completely between waterings.
- Trim mushy roots and repot in well-draining soil if rot is present.
Expert Tip: Consistency is vital—avoid placing snake plants near exterior doors or windows that cause temperature swings.
2. Brown Leaf Tips
Symptoms: The tips of otherwise healthy leaves appear dry, crispy, or dark brown.
Environmental Triggers:
- Low humidity or excessive heat
- Salt buildup from tap water, especially in dry climates
How to Fix:
- Group plants together or use a pebble tray to gently raise humidity.
- Water with distilled or filtered water to avoid mineral accumulation.
- Maintain humidity levels between 30% and 50%, and avoid placing plants near heaters or vents.
3. Mushy or Soft Leaves
Symptoms: Leaves collapse, feel squishy, and may ooze when pressed.
Environmental Triggers:
- High humidity combined with poor airflow
- Overwatering, especially in cool or low-light conditions
How to Fix:
- Remove and discard affected tissue.
- Place the plant in a warm, well-ventilated area to dry out.
- Repot in fresh, fast-draining mix and ensure the pot has drainage holes.
4. Curling Leaves
Symptoms: Leaves curl inward or twist.
Environmental Triggers:
- Underwatering, especially during hot, dry weather
- Sudden changes in light intensity or temperature
How to Fix:
- Water the plant thoroughly whenever the top 2–3 inches of soil feel dry.
- Avoid abrupt moves between different light or temperature zones.
- Inspect for pests, which can worsen environmental stress.
5. Drooping or Falling Over
Symptoms: Leaves bend or collapse from the base.
Environmental Triggers:
- Weak roots from overwatering in low-light conditions
- Rapid temperature changes or drafts
How to Fix:
- Repot into a heavier, wider container for stability.
- Place in a location with consistent temperatures and indirect light.
- Avoid exposing the plant to cold drafts or direct blasts from air conditioners and heaters.
6. Slow or Stunted Growth
Symptoms: Little to no new growth, or leaves remain small.
Environmental Triggers:
- Insufficient light intensity
- Cool temperatures, especially below 60°F (15°C)
How to Fix:
- Move the plant closer to a bright, east- or west-facing window.
- Maintain stable indoor temperatures.
- Fertilize only during active growth in spring and summer.

7. Pest Infestations (Thrips, Mealybugs, Spider Mites)
Symptoms:
Silvery streaks, stippling, webbing, tiny crawling insects, sticky residue, or white cottony masses on leaves and stems.
Common Snake Plant Pests:
Snake plants are susceptible to several sap-sucking pests, including:
- Spider mites: These tiny bugs are usually found under leaves. Infestations cause fine webbing, yellow stippling, and a dusty appearance. Spider mites thrive in dry, warm environments.
- Mealybugs: Small, white, cottony insects that cluster in leaf axils and along stems. They produce honeydew, which makes the leaves sticky and can cause black sooty mold.
- Thrips: Slender, fast-moving insects that scrape leaf surfaces, causing silvery streaks and distorted growth.
- Aphids: Less common but can appear as soft, green, or black clusters on new growth.
- Fungus gnats: Their larvae feed on roots in overly damp soil, which can stress the plant and make it more vulnerable to disease.
How Pests Affect Snake Plants:
These pests damage snake plants by sucking sap, weakening the plant, and making it more susceptible to secondary infections and stress. Severe infestations can cause yellowing, curling, and dropping leaves.
Prevention and Early Detection:
- Check new plants thoroughly and keep them separate for a few weeks before adding them to your current collection.
- Regularly inspect the undersides of leaves and crevices for any signs of pests.
- Maintain good air circulation and avoid overwatering, as damp, stagnant conditions favor pests and fungal growth.
- Use a damp cloth to wipe the leaves, which helps remove dust and early-stage pests.
Treatment Options:
- Mechanical removal: For minor infestations, remove pests by wiping them off with a damp cloth or rinsing the plant with lukewarm water.
- Insecticidal soap or neem oil: Apply to affected areas, ensuring thorough coverage of both upper and lower leaf surfaces. Do this again every 7 to 10 days until the pests are gone.
- Isolate affected plants: This helps prevent the disease from spreading to other houseplants.
- Biological controls: Predatory mites or ladybugs can help manage pest populations in larger collections, though this is less common indoors.
According to the University of Maryland Extension [1], regular monitoring and early intervention are key to managing spider mites and mealybugs on houseplants (University of Maryland Extension: “Spider Mites on Houseplants”).
The Colorado State University Extension [2] recommends using insecticidal soaps for mealybug and aphid control, emphasizing the importance of repeated treatments for full eradication.
Expert Tip: Always test any spray on a small area first to check for leaf sensitivity, and avoid applying oils or soaps in direct sunlight to prevent leaf burn.
8. Leaf Spot or Scarring
Symptoms: Circular brown, black, or sunken spots.
Environmental Triggers:
- High humidity with poor airflow
- Water droplets on leaves in low light
How to Fix:
- Prune damaged areas and increase spacing between plants.
- Water at the base, not on the leaves.
- Use a small fan for gentle air movement if needed.
9. Wrinkled Leaves
Symptoms: Leaves appear shriveled and lose firmness.
Environmental Triggers:
- Extended drought (low humidity and infrequent watering)
- Heat stress from direct sun or high indoor temperatures
How to Fix:
- Water thoroughly and increase humidity if air is very dry.
- Move out of direct sun during summer heatwaves.
10. Leaves Turning Pale or Washed Out
Symptoms: Faded color, especially in variegated varieties.
Environmental Triggers:
- Insufficient light intensity
- Prolonged periods in deep shade
How to Fix:
- Relocate to a spot with bright, indirect light.
- Rotate the plant regularly for even exposure.
