Succulent plants have gained immense popularity in recent years, and it’s not hard to see why. These resilient and vibrant plants come in a stunning array of shapes, sizes, and colors, adding a touch of nature to our indoor and outdoor spaces. However, if you’ve noticed your once-green succulent turning purple, you might be left wondering why this color transformation is occurring. In this comprehensive guide, we’ll explore the various reasons behind this intriguing phenomenon, providing you with insights into the potential causes, effects, and solutions.
Why Is My Green Succulent Turning Purple?
A green succulent can transform into shades of purple due to various environmental factors. Temperature stress, often triggered by cold weather in late autumn and winter, prompts the development of purple pigments known as anthocyanins. Conversely, excessive sunlight can lead to sunburn, causing purple coloration, while insufficient light diminishes chlorophyll production, resulting in purple leaves. Color changes can also stem from watering issues, soil quality, nutrient deficiencies, and pest infestations. To maintain your succulent’s natural beauty, let’s delve deeper into each of these factors influencing their color.
1. Environmental Factors
Temperature Stress and Seasonal Variations
One of the most common reasons for a green succulent turning purple is temperature stress. Succulents are known for thriving in arid, sunny conditions. However, when exposed to cold temperatures, especially during late autumn and winter months, succulents may react by changing their color. This is often a natural response to environmental conditions, as purple pigments, called anthocyanins, act as a protective mechanism against extreme cold.
In early spring and throughout the growing season, succulents tend to regain their vibrant green color as they recover from the stress of the winter months.
Solution: Protect your succulents from extreme cold temperatures during late autumn and winter. Ensure they are kept within an ideal temperature range for their well-being. Consider bringing them indoors if necessary.
Sunlight Exposure and Bright Light
Succulents indeed thrive in bright light conditions, but it’s crucial to strike the right balance. Excessive exposure to too much sunlight can trigger color changes, turning a once-green succulent into a purple hue. This transformation is often an indicator of sunburn, and it is particularly conspicuous when the purple coloration is concentrated on the sun-facing side of the plant. Such sunburn occurs because the plant’s natural protection mechanisms, such as the production of anthocyanin pigments, are activated in response to the heat and light stress.
To address this issue and maintain the health and appearance of your succulent, it’s essential to make careful adjustments to its light exposure. If you notice your succulent is turning purple due to excessive sunlight, consider relocating it to a spot with indirect sunlight or partial shade. By providing a more suitable lighting environment, you can help prevent further sunburn and allow your succulent to thrive without the stress that leads to color changes. This deliberate placement can ensure that your succulent maintains its vibrant green coloration while still enjoying the benefits of ample sunlight.
Solution: If your succulent is turning purple due to excessive sunlight, the best way to rectify this is to move it to a location with indirect sunlight or partial shade to prevent further sunburn.
Lack of Light and Insufficient Sunlight
Conversely, insufficient light can also cause color changes in succulents, marking an adverse effect on their appearance and overall health. When succulents do not receive an adequate amount of sunlight, they may struggle to maintain their characteristic green color, leading to the emergence of a purple hue. This shift in coloration is primarily due to the reduction in chlorophyll production, a crucial component for photosynthesis, under low-light conditions.
Solution: Provide your succulent with enough indirect or bright light, especially if it’s an indoor plant, to maintain its green color. Consider using grow lights if natural light is limited.
2. Watering and Drainage Issues
Overwatering and Poor Drainage
Overwatering is an extremely common problem that succulent owners face. When succulents receive too much water or don’t have adequate drainage, they can suffer from root rot. This condition is often accompanied by a change in leaf color, turning from green to purple. Overwatering can be especially problematic during the winter months when succulents require less frequent watering.
Solution: Plant your succulent in well-draining soil and a pot with drainage holes to prevent excess water and root rot. Establish a consistent watering schedule and let the soil dry out between waterings, especially during winter.
Underwatering and Lack of Water
On the flip side, not providing your succulent with enough water can also lead to color changes. If your succulent leaves appear wrinkled or start to turn purple, it’s a sign of dehydration. Succulents have the ability to store water in their leaves, and when they’re not receiving enough moisture, they may react by changing color.
Solution: Adjust your watering schedule to ensure your succulent receives the right amount of water. Water when the soil is dry to the touch, but not bone dry during the growing season.
3. Soil and Nutrient-Related Factors
Poor Soil
The type of soil and the nutrients available to your succulent can greatly impact its color. Poor soil quality or nutrient deficiencies can lead to color changes. If the soil lacks essential nutrients, such as nitrogen or magnesium, your succulent may struggle to maintain its green color and start turning purple.
Solution: Repot your succulent in well-draining soil specifically designed for succulents. Use a balanced succulent fertilizer during the growing season to ensure your plant gets essential nutrients.
Specific Nutrient Requirements
A lack of nutrients isn’t the only soil-related issue that can cause color changes in succulents. Some succulent species require more specific nutrient ratios. For instance, the Christmas cactus can develop a purple coloration if they lack certain nutrients, especially phosphorus.
Solution: Research the specific nutrient requirements of your succulent species and adjust your care regimen accordingly. Provide the necessary nutrients to maintain vibrant colors.
4. Pests and Fungal Infections
Pests
Color changes in succulents can also be a result of pests. One of the common culprits is spider mites. These tiny arachnids can infest succulents, sucking out the plant’s juices and causing damage to the leaves. In response to this stress, the leaves may turn yellow, red, or purple.
Solution: Regularly inspect your succulents for pests like spider mites and take appropriate pest control measures. Isolate affected plants to prevent the spread of pests.
Fungal Infections
Fungal infections can affect succulent leaves, leading to discoloration and even black spots. Fungus gnats, in particular, can create a moist environment in the soil that encourages fungal growth and causes leaves to turn purple or develop brown spots.
Solution: Ensure good drainage and well-draining soil to prevent a fungal infection. Maintain proper watering practices to create an environment less conducive to fungal growth.
5. Age and Succulent Varieties
Age of the Succulent
The age of your succulent can also influence its color. Young succulents often exhibit more vibrant colors, whereas older succulents might have a more muted appearance. While this isn’t a problem per se, it’s essential to understand that age-related color changes can be perfectly natural.
Solution: Understand that age-related color changes are natural. There is no need for specific solutions in this case.
Variety-Specific Coloration
Different succulent types and varieties exhibit various colors as part of their natural characteristics. Some succulents are naturally purple or have purple accents in their leaves, while others might transition between different shades depending on the season or environmental conditions.
There are also some succulent varieties that exhibit unique color changes as part of their natural characteristics. For instance, the “Echeveria Chroma” variety may naturally transition from green leaves to purple during different seasons.
Solution: Research the specific color patterns of your succulent variety to differentiate between normal color changes and signs of stress or disease.
6. Stress Caused By Sudden Changes
Succulents exhibit their unique coloration as a defense mechanism against the potential damage caused by extreme temperature fluctuations. The sudden exposure to intense heat or cold can disrupt the delicate balance of their internal processes, prompting the production of protective pigments and the subsequent color transformation.
To further safeguard the well-being of your succulent and ensure its vibrant appearance, consider providing a transition period that spans several days or even weeks, depending on the magnitude of the environmental change. This gradual acclimatization allows your plant to adapt comfortably to its new surroundings and minimizes the risk of sudden temperature stress, promoting a healthier and more visually appealing succulent.
Solution: Gradually acclimate your succulent to new conditions when moving it from indoors to outdoors or vice versa to avoid sudden temperature changes.
7. Extended Periods of Stress and Neglect
Extended neglect and a lack of care can significantly impact the health and appearance of your succulent. This scenario often arises due to a combination of multiple factors, such as infrequent or insufficient watering, the use of poor-quality soil that hinders essential nutrient uptake, and a shortage of adequate light, all of which can contribute to the plant’s gradual decline in vitality and color.
To rectify this situation and restore your succulent to its former vibrancy, it’s essential to implement a comprehensive care regimen. This involves not only providing your plant with a consistent and well-tailored watering schedule but also ensuring it is potted in high-quality, well-draining soil that supports the growth and nutrition of your succulent. Moreover, by offering your plant sufficient access to natural or artificial light, you can effectively prevent prolonged stress and neglect, fostering a more resilient and visually striking succulent that thrives in its environment.
