Is Your Plant Feeling Under the Weather? 10 Telltale Signs to Watch Out For

As a plant parent, you’ve undoubtedly put a lot of effort into creating the perfect environment for your green friends to thrive.

But despite your best intentions, sometimes plants can still become unwell.

Just like humans, plants can exhibit various signs of distress, and it’s essential to recognize these symptoms early to nurse your plant back to health.

In this guide, we’ll discuss 10 telltale signs that your plant is unwell and give you expert tips to help your green companions bounce back.

1. Yellowing Leaves

One of the most common indicators of an unhappy plant is yellowing leaves. This discoloration can signify various issues, from nutrient deficiencies to overwatering. To determine the root cause, examine your plant’s care routine and environment closely.

• Nutrient deficiency: A lack of essential nutrients, such as nitrogen, can cause leaves to turn yellow. Make sure you’re providing your plant with the appropriate fertilizer and soil mix.
• Overwatering: Yellowing leaves can also be a sign of root rot caused by overwatering. Check the moisture level in the soil before watering and ensure your plant’s pot has proper drainage.

2. Wilting

Another sign that your plant is under the weather is wilting. This symptom can be caused by various factors, including insufficient water, root damage, and even too much sunlight.

• Watering issues: Make sure you’re providing the right amount of water for your plant, as underwatering can lead to wilting. Conversely, overwatering can suffocate the roots and cause wilting as well.
• Root damage: In some cases, wilting may be a sign of root damage caused by pests or disease. Examine the roots and soil for any signs of infestation or rot.

3. Stunted Growth

If you’ve noticed that your plant isn’t growing as it should be, it could be a sign that something’s amiss. Stunted growth may indicate issues with temperature, light, or nutrients.

• Temperature: Ensure your plant is in a suitable environment, with the right temperature range for its specific needs.
• Light: Make sure your plant is receiving the appropriate amount of sunlight, as both too much and too little light can stunt growth.
• Nutrients: A lack of vital nutrients can also lead to stunted growth. Fertilize your plants according to their specific requirements and keep an eye on their soil quality.

4. Leaf Drop

When your plant starts shedding leaves more than usual, it could be a sign of distress. Leaf drop can be caused by overwatering, temperature fluctuations, or pest infestations.

• Overwatering: As mentioned earlier, overwatering can cause root rot, leading to leaf drop. Monitor your plant’s water intake and adjust as needed.
• Temperature fluctuations: Sudden changes in temperature can stress your plant, causing it to shed leaves. Maintain a consistent temperature and avoid placing your plant near drafty windows or heating vents.
• Pest infestations: Pests such as spider mites and aphids can cause leaf drop. Check your plant for signs of infestation and treat accordingly with insecticidal soaps or other remedies.

5. Brown or Black Spots on Leaves

Brown or black spots on your plant’s leaves can be a sign of fungal or bacterial infections. These infections can spread quickly, so it’s essential to address the issue promptly.

• Fungal infections: Fungi like powdery mildew and leaf spot can cause brown or black spots on leaves. Treat these infections with a fungicide and ensure proper airflow around your plant to prevent future outbreaks.
• Bacterial infections: Bacterial leaf spots may appear as dark, water-soaked spots on the leaves. Remove infected leaves and apply a copper-based bactericide to prevent the spread of the infection.

6. Leggy Growth

If your plant is growing tall and spindly with few leaves, it’s likely experiencing leggy growth. This issue is typically caused by insufficient light, causing the plant to stretch toward the light source.

• Light: Move your plant to a sunnier spot or supplement with artificial light to encourage fuller, bushier growth.

7. Unhealthy Roots

Healthy roots are critical for a thriving plant, so unhealthy roots can lead to various other issues. Look for root damage caused by overwatering, pests, or disease.

• Overwatering: Soggy soil can cause root rot, which leads to damaged, unhealthy roots. Ensure proper drainage and avoid overwatering your plant.
• Pests: Soil-dwelling pests like root aphids and nematodes can damage your plant’s roots. Treat infestations with appropriate insecticides or biological controls.

8. Holes or Chewed Edges on Leaves

Finding holes or chewed edges on your plant’s leaves is a sure sign of a pest problem. Common culprits include caterpillars, slugs, and beetles.

• Pest control: Inspect your plant for pests and treat accordingly with either natural remedies or chemical insecticides. Be vigilant in checking for pests to prevent future infestations.

9. Curling or Distorted Leaves

When your plant’s leaves appear curled or distorted, it can signify various issues, from pests to nutrient deficiencies or even herbicide damage.

• Pests: Aphids and spider mites can cause leaves to curl or distort. Treat infestations with insecticidal soaps or other remedies.
• Nutrient deficiencies: A lack of essential nutrients like potassium can cause leaf curling. Ensure your plant is receiving the appropriate nutrients through fertilization and proper soil quality.
• Herbicide damage: Exposure to certain herbicides can distort your plant’s leaves. If you suspect your plant has been exposed to herbicides, wash the leaves gently with water and remove any affected foliage. Be cautious when using herbicides near your plants in the future.

10. Mold or Mildew Growth

The presence of mold or mildew on your plant or its surrounding soil can indicate high humidity levels or poor air circulation, which can lead to various health issues for your plant.

• Humidity: Ensure your plant is in an environment with appropriate humidity levels, and consider using a dehumidifier if necessary.
• Air circulation: Proper airflow is essential to prevent mold and mildew growth. Space your plants out and consider using a fan to improve air circulation around your green companions.
