Succulents remain one of the most popular plants in the world. These plants are relatively easy to care for and require minimal maintenance to thrive. Although succulents seem like the perfect low-maintenance plant, they benefit from a little bit of stress. This can be sun stress or water stress depending on the type of succulent you have.
So, what are the surprising benefits of stressing succulents? Stressing succulents enhances coloration, promotes growth, and increases drought tolerance among your succulents. This technique may induce unique morphological changes that can trigger visually captivating traits in your plants. Succulent stress can also encourage root development and help to boost overall health and hardiness. For instance, sun-stressing succulents is a great way to bring out beautiful colors. As the leaves of certain species get more sunlight, they turn brilliant shades of magenta, orange, red or yellow.
This blog post discusses some of the surprising benefits of stressing your succulents. Read on to find out everything you need to know.
What Is Succulent Stress?
Succulent stress might sound like a negative condition, but it’s a technique used by succulent enthusiasts to enhance the beauty of their plants.
The term refers to the process of deliberately exposing succulents to certain conditions that cause them to change color, a phenomenon often referred to as “blushing” or “color stress.”
In their native habitats, succulents are often exposed to harsh conditions such as intense sunlight, low water availability, and temperature fluctuations.
These conditions can cause these plants to produce pigments such as anthocyanins and carotenoids, which act as sunscreen and protect the plant cells from damage.
These pigments also cause the plants to display vibrant colors, ranging from deep reds and purples to bright oranges and yellows.
When grown in ideal conditions indoors or in shaded outdoor areas, many succulents retain the green color.
However, by mimicking the harsh conditions of their natural habitats, you can induce stress in your succulents and bring out these beautiful colors.
The three most common types of stress for succulents are light, water, nutrient, and temperature. Below is a summary of each:
Sun Stress
One of the most common ways to induce succulent stress is through increased sunlight exposure.
Gradually moving your succulent to a location that receives more direct sunlight can trigger the production of protective pigments and result in color changes.
However, it’s important to make this transition slowly to prevent sunburn.
Start by exposing the plant to an additional hour of sunlight each day and monitor the plant closely for signs of sunburn, such as white or brown patches on the leaves.
Water Stress
Succulents are drought-tolerant plants, and reducing their water intake can stimulate stress responses.
To induce water stress, extend the time between watering sessions and allow the soil to dry out completely before watering again.
Be careful not to overdo it, though, as prolonged periods of drought can cause the plant to wilt and eventually die.
Temperature Stress
Exposing succulents to cooler temperatures, particularly at night, can induce stress and bring out vibrant colors.
This method works best in the fall and winter when cooler temperatures occur naturally.
Keep in mind, however, that not all succulents can tolerate freezing temperatures, so be sure to research the specific needs of your plants before attempting this method.
Nutrient Stress
Limiting the amount of nutrients available to your succulent or overfertilizing in some cases can also induce stress. This can be achieved by using a low-nutrient soil mix and limiting the use of fertilizers.
However, nutrient stress should be done cautiously since prolonged nutrient deficiency can lead to poor plant health.
What Are the Surprising Benefits of Stressing Succulents?
Now that we’ve discussed the basics of stressing succulents, let’s take a look at some of the benefits this technique can offer.
1. Enhanced Coloration
Stressing succulents can enhance their coloration through several mechanisms. These plants possess pigments such as anthocyanins and carotenoids, contributing to their colors.
Intense or direct sunlight serves as a key stressor, prompting succulents to produce more pigments as a protective response.
The increased pigment production helps shield the plants from excessive light and potential sun damage. Ultraviolet (UV) radiation, which is part of sunlight, also acts as a stressor, causing succulents to produce higher amounts of protective pigments.
These pigments absorb and dissipate harmful UV rays. As a result, succulents exhibit deeper or more vibrant colors in their leaves or stems.
Temperature fluctuations can also impact succulent coloration. Cooler temperatures induce the production of more anthocyanins, leading to reddish or purplish tones. This response helps protect the plants from damage caused by low temperatures.
Water stress is another crucial factor. Limited watering or drought conditions prompt succulents to produce more pigments as a protective measure.
The reduced availability of water triggers an increased pigment production, shielding the tissues from excessive sunlight and reducing water loss through evaporation.
Nutrient availability plays a role as well. Certain nutrients, such as nitrogen and phosphorus, are essential for proper pigment synthesis.
Adequate nutrient levels support optimal pigment production, resulting in intense and rich coloration.
Conversely, nutrient deficiencies can compromise pigment production, leading to less vibrant colors in succulents.
It’s important to note that the specific color changes observed in succulents can vary depending on factors like species, genetics, and environmental conditions.
While stressing succulents enhances coloration, it’s crucial to balance the stress levels to avoid excessive harm to the plants.
2. Promotes Compact Growth
You can promote compact growth and encourage a fuller, bushier appearance by subjecting succulents to controlled stress, such as limited water or nutrients.
This response is due to the hormone ethylene produced in plants when they experience stress or limited resources.
Ethylene produces a thickening effect on stems, encouraging branch formation. It also influences root development, stimulating the production of new roots for better nutrient uptake.
As a result, stressed succulents tend to form a bushier and denser shape, creating an attractive aesthetic.
3. Promotes Plant Hardiness
Stressing succulents can also enhance their hardiness by increasing their tolerance to different conditions. Constant stress exposure helps build the plant’s resilience and ability to survive in harsher environments.
For example, intense sunlight activates photo-protective pathways that allow plants to tolerate high light exposure levels better.
Similarly, water stress increases the plant’s tolerance to drought conditions and other environmental stressors.
Exposing succulents to cooler temperatures can also strengthen their cells and make them more resilient against cold weather or frost.
In the same way, nutrient deficiencies trigger an adaptation response in succulents that helps them cope with nutrient-poor environments.
Ultimately, stressing succulents strengthens their cellular mechanisms and makes them more capable of withstanding environmental stressors.
4. Induces Unique Morphological Changes
Stressing succulents can trigger distinct morphological changes, making them even more visually captivating.
For example, certain stressors can cause the development of interesting growth patterns, like crested or monstrose forms, where the stems become twisted and contorted.
This occurs due to a mutation in the meristematic cells responsible for plant growth and development.
Exposure to stressors can cause changes in their activity, inducing unusual stem forms or other morphological features that add to the aesthetic appeal of succulents.
Other unique morphological changes that may occur as a result of stressing succulents include variegation, where leaves or stems display different colors, and pachyforms, where the plants become more densely packed with thicker stems.
5. Encourages Root Development
Controlled stress can stimulate the growth and development of succulent roots. You can promote a more extensive and robust root system by stressing the plants slightly through techniques such as root pruning or partial water withholding.
Stronger roots allow succulents to better absorb moisture and nutrients from the soil, boosting their health.
Stressing succulents can also help them recover more quickly after repotting or transplanting. Increasing the plants’ root strength can ensure faster recovery and better adaptation to a new environment.
6. Increased Resilience to Pests and Diseases
Stressing succulents can enhance their resilience to pests and diseases. When succulents undergo controlled stress, they often develop stronger cell walls and produce secondary metabolites, such as phytochemicals.
These defense mechanisms can deter pests and inhibit the growth of pathogens, making the plants more resistant to damage.
Furthermore, stressing succulents may reduce their susceptibility to certain diseases. This is due to the increased production of protective pigments, which help shield the plants from pathogen damage.
7. Facilitates Propagation
Stressing succulents can promote successful propagation through various methods. For example, by subjecting a succulent to partial stem or leaf damage, the stress signals can trigger the plant’s natural response to generate new roots and shoots.
This process, known as vegetative propagation, can be a reliable and effective way to propagate and multiply succulents, allowing you to expand your succulent collection.
Keep in mind that it’s important to follow proper propagation techniques and take good care of the plants for successful outcomes.
Final Thoughts
Stressing succulents can effectively encourage coloration, promote compact growth, induce unique morphological changes, and enhance their resilience.
This technique can be achieved through exposure to different types of stress, such as intense sunlight, water deprivation, cooler temperatures, and nutrient deficiencies.
However, it’s important to moderate the stress levels and avoid over-stressing the plants.
