Unfortunately there are some plants and flowers that struggle. One of those that often needs a little extra TLC is the corn plant.
But if your corn plant looks like it’s on its last legs, don’t panic – there are several steps you can take to revive it.
These simple tips should give you all you need to bring your corn plant back to life.
1. Assess the Situation
Check the Symptoms
Before you can revive your corn plant you need to understand what’s wrong. Common signs of distress in corn plants include:
- Yellowing leaves
- Brown tips
- Drooping or wilting
- Stunted growth
Identify the Cause
Common issues include:
- Overwatering: Too much water can lead to root rot which is a common problem with corn plants.
- Underwatering: Not enough water can cause the plant to wilt and the leaves to turn brown.
- Poor light conditions: Both too much and too little light can cause issues for the corn plant.
- Pest infestation: Insects like spider mites, mealybugs and scale can damage your plant.
- Nutrient deficiencies: Lack of essential nutrients can lead to yellowing leaves and poor growth.
2. Adjust Your Watering Routine
Overwatering
Corn plants are susceptible to root rot if they are overwatered. Signs include yellowing leaves and a mushy stem.
- Allow the soil to dry out before watering again. Stick your finger about an inch into the soil to check moisture levels. If it’s still damp wait a few days and check again.
- The pot needs to have good drainage. If water collects at the bottom it can lead to root rot. Consider repotting in a container with drainage holes if necessary.
Underwatering
If your plant is drooping and the soil is dry it’s likely underwatered.
- Water thoroughly, allowing excess water to drain out. Make sure the water reaches the roots by watering until you see water coming out of the drainage holes.
- Try to have a regular watering schedule, typically once a week. Adjust based on the plant’s environment and needs.
3. Improve Lighting Conditions
Find the Right Spot
Corn plants thrive in bright, indirect light. Too much direct sunlight can scorch the leaves while too little light can cause yellowing.
- Place your plant near a window with filtered light. North or east-facing windows are usually ideal.
- Avoid direct afternoon sun. If the only spot is in direct sunlight use a sheer curtain to diffuse the light.
Supplement with Artificial Light
If natural light is insufficient consider using a grow light.
- LED grow lights are a great option. They are energy-efficient and provide the spectrum of light that plants need.
- Keep the light on for 12-14 hours a day. Place the grow light about 6-12 inches above the plant for best results.

4. Address Nutrient Deficiencies
Fertilizing Your Corn Plant
Lack of nutrients can lead to yellowing leaves and poor growth.
- Use a balanced liquid fertilizer diluted to half strength. Look for a 10-10-10 or 20-20-20 formula.
- Feed your plant every 4-6 weeks during the growing season (spring and summer). Reduce feeding in the fall and winter when the plant’s growth slows down.
Repotting
If your plant has been in the same soil for years it might be time for fresh soil.
- Choose a well draining potting mix. A mix designed for houseplants or a blend of peat, perlite and vermiculite works well.
- Repot in spring for best results. Gently remove the plant from its current pot, loosen the roots and place it in a new pot with fresh soil.
5. Pest Control
Common Pests
Corn plants can fall prey to pests such as spider mites, mealybugs and scale.
- Inspect the plant regularly for signs of pests. Look for tiny insects, sticky residue, webbing or small bumps on the leaves and stems.
- Use a magnifying glass to get a closer look if needed.
Treatment Options
If you spot pests take immediate action.
- Wipe leaves with a mixture of water and mild soap. This can remove and kill many pests.
- Use insecticidal soap or neem oil for severe infestations. Follow the instructions on the product label for best results.
- Quarantine the plant if possible to prevent the pests from spreading to other plants.

6. Proper Humidity Levels
Maintain Humidity
Corn plants prefer moderate to high humidity. Dry air can cause leaf tips to turn brown.
- Use a humidity tray or a room humidifier. Place the pot on a tray filled with pebbles and water making sure the pot sits above the water level.
- Mist the leaves regularly, especially in winter when indoor air tends to be drier. Use room-temperature water for misting.
Grouping Plants
Placing multiple plants together can help maintain humidity.
- Create a mini indoor jungle to benefit all your plants. The collective transpiration from the plants increases the humidity around them.
- Make sure there’s enough space for air circulation to prevent mold. Avoid crowding the plants too closely together.
7. Pruning and Cleaning
Pruning Dead or Damaged Leaves
Remove any dead or yellowing leaves to encourage new growth.
- Use sharp, clean scissors or pruning shears. Disinfect the blades with rubbing alcohol before and after pruning to prevent the spread of disease.
- Cut leaves at the base to avoid leaving stubs. Make clean cuts to reduce stress on the plant.
Cleaning the Leaves
Dust can block light and hinder photosynthesis.
- Wipe the leaves with a damp cloth every few weeks. Support the leaf with one hand and gently wipe with the other.
- Avoid using leaf shine products as they can clog pores. Stick to water or a mild soap solution if needed.
8. Monitor and Adjust
Regular Checkups
Keep an eye on your corn plant and make adjustments as needed.
- Check soil moisture levels regularly. Use a moisture meter or simply stick your finger into the soil.
- Watch for new signs of distress or pest activity. Early detection can prevent bigger problems down the line.
Seasonal Changes
Adjust your care routine based on the season.
- Reduce watering in winter when growth slows down. The plant will need less water during its dormant period.
- Increase humidity during dry months. Use a humidifier or mist the leaves more frequently in winter.
Final Thoughts
Reviving a dying corn plant requires patience and attention to detail. But by following these steps and you can bring your corn plant back to life.
Remember that each plant is unique through so observe closely and respond accordingly. Without too much effort you should have your corn plant back and thriving again in no time.
