Why is my Calibrachoa dying?

If you’ve noticed that your Calibrachoa plant is not thriving as expected, you may be wondering why it is dying and what steps you can take to revive it. Calibrachoa, commonly known as Million Bells, is a popular flowering plant appreciated for its vibrant colors and ability to attract pollinators.

However, several factors can contribute to the decline and eventual death of these plants. In this article, we will explore the possible reasons behind the dying Calibrachoa and provide useful insights to help you revive and maintain their health.

1. Insufficient Watering

One common reason for Calibrachoa plants to wither and die is insufficient watering. Calibrachoa requires consistent moisture in order to thrive, and inadequate watering can lead to dehydration and stress.

Here are some issues related to watering that may contribute to the decline of your Calibrachoa:

Inconsistent Watering:

Calibrachoa plants prefer well-drained soil, but they should not be allowed to dry out completely between watering. Inconsistently watering the plant can cause stress and lead to wilting or eventual death.

Ensure that you water your Calibrachoa regularly, but avoid overwatering, as it can lead to root rot.

Improper Drainage:

Calibrachoa plants are susceptible to root rot if their roots sit in waterlogged soil. Poor drainage can suffocate the roots and hinder absorption of nutrients, leading to plant decline and death.

To prevent this, make sure the pot or planting area has adequate drainage holes to allow excess water to escape.


On the other hand, underwatering can also cause Calibrachoa plants to wilt and eventually die. If the soil becomes too dry, the plant will not receive the necessary moisture to support its growth and survival.

Monitor the moisture level of the soil regularly and water your Calibrachoa whenever the top inch of soil feels dry to the touch.

2. Nutrient Deficiencies

Calibrachoa plants require proper nutrition to thrive. Nutrient deficiencies can weaken the plant’s immune system, making it more susceptible to disease and other stressors.

Here are a few common nutrient deficiencies that can contribute to the decline of Calibrachoa:

Nitrogen (N) Deficiency:

Nitrogen is an essential nutrient for plant growth and helps facilitate the production of chlorophyll. A nitrogen deficiency can result in stunted growth, yellowing leaves, and overall poor plant health. To address this deficiency, you can apply a balanced fertilizer that contains nitrogen according to the manufacturer’s instructions.

Iron (Fe) Deficiency:

Iron deficiency is characterized by yellowing leaves with distinct green veins. Calibrachoa plants with iron deficiency may exhibit reduced growth and poor flowering. Applying iron chelates or iron sulfate to the soil can help correct this deficiency and restore the plant’s health.

Magnesium (Mg) Deficiency:

Magnesium is crucial for photosynthesis and chlorophyll production. Calibrachoa plants with magnesium deficiency may display yellowing between leaf veins, leading to a mottled appearance. Adding magnesium sulfate or Epsom salts to the soil can help alleviate this deficiency and revitalize the plant.

3. Pest Infestations

Pests can wreak havoc on Calibrachoa plants, causing damage to leaves, stems, and flowers. If left untreated, severe infestations can weaken the plant and eventually lead to its demise. Some common pests that can harm Calibrachoa include:


Aphids are tiny insects that suck sap from plants, causing leaves to curl, yellow, and distort. These pests can weaken Calibrachoa and transmit viruses. Regularly inspect your plants for aphids, and if detected, you can spray them with a strong stream of water or use insecticidal soap to control their population.

Spider Mites:

Spider mites are tiny arachnids that feed on plant fluids, causing stippling, yellowing, and webbing on leaves. They thrive in dry conditions. To control spider mites, you can use a miticide or insecticidal soap and ensure the plants are adequately watered to increase humidity and discourage infestations.


Whiteflies are small, flying insects that feed on plant sap, leading to leaf yellowing, wilting, and honeydew secretion. They can be challenging to control due to their rapid reproduction. Using yellow sticky traps or applying insecticidal soap can help manage whitefly populations and protect your Calibrachoa plants.

4. Disease Issues

Several diseases can affect Calibrachoa plants, compromising their health and vitality. Fungal and bacterial infections can spread rapidly in humid and crowded growing conditions. Here are some common diseases that can cause your Calibrachoa to die:

Botrytis Blight:

Botrytis blight, or gray mold, can lead to brown spots, wilting, and decay on Calibrachoa flowers and foliage. High humidity and excessive moisture contribute to the development and spread of this fungal disease.

To prevent Botrytis blight, avoid overhead watering, provide good air circulation, and remove infected plant parts.

Root Rot:

Root rot, caused by fungi like Pythium or Phytophthora, is a common problem in Calibrachoa plants grown in poorly drained soil. Infected roots become dark, mushy, and fail to absorb water and nutrients properly.

To prevent root rot, ensure proper drainage and avoid overwatering. If root rot is detected, replant the Calibrachoa in fresh, well-drained soil.

Bacterial Leaf Spot:

Bacterial leaf spot appears as dark, water-soaked lesions on leaves, eventually leading to tissue collapse and plant decline. Warm and humid conditions promote the spread of this bacterial disease.

Preventive measures include avoiding overhead watering and removing infected plant material. Applying copper-based fungicides can help manage bacterial leaf spot.

5. Environmental Stress

Calibrachoa plants can suffer from various environmental stressors that impact their overall health and survival. Here are a few stress factors to consider:

Extreme Temperatures:

Calibrachoa plants prefer moderate temperatures between 60-75°F (15-24°C). Exposure to extreme heat or cold can cause the plant to wilt, decline, and eventually die. Protect your plants from extreme temperature fluctuations by providing adequate shade or bringing them indoors during harsh weather conditions.

Excessive Sun Exposure:

While Calibrachoa plants enjoy full sun, excessive exposure during the hottest parts of the day can cause leaf scorching and stress. Make sure your plants have access to partial shade during the hottest hours, especially in regions with intense sunlight.


Overcrowding can lead to poor air circulation and increased susceptibility to diseases and pests. Give your Calibrachoa plants enough space to grow and ensure proper spacing between them to promote healthy growth.

Inadequate Light:

Insufficient light can lead to weak and leggy Calibrachoa plants with reduced flower production. Make sure to place your plants in a location that receives at least 6 hours of direct sunlight per day for optimal growth.

By identifying and addressing these potential issues, you can increase the chances of reviving your dying Calibrachoa plants and help them thrive once again.

Remember to provide them with adequate water, nutrients, and protection from pests and diseases, while also ensuring they are placed in an ideal growing environment. With proper care and attention, your Calibrachoa plants can rebound and provide you with their stunning blooms for a long time to come.
