Although photosynthesis requires sunshine, certain plants might receive too much of it. While some succulents can be grown in full sun (defined as 6+ hours of direct sunshine each day), not all of them can, and some may even suffer from too much sunlight. Sunburned leaves will appear brown or black and could start to shrink or callus. Moving your plant to a location with less exposure or intense light is the best technique to treat sunburn on that plant. While untouched areas of the plant will continue to be in good health, sunburned leaves will never fully recover.
By observing other leaf symptoms, you can tell sunburn from rot. A plant that has recently been exposed to the light will still have big, thick leaves that have started to turn black or brown but may still be glossy. Older sunburns will be dry, shriveled, or even fully desiccated, and they will be black or brown in color. The appearance of rotted and overly wet leaves will be mushy and wrinkled.
If a plant at the store or one you own has sunburn, it probably wasn’t properly cared for and was exposed to too much light at some point rather than being sick and dying rapidly. Remember that burnt segments frequently shrink up, so even though the plant may not seem attractive, it may still be healthy and continue to grow for many years. The easiest approach to avoid purchasing plants with sunburns is to only purchase them from local, independent nurseries and vendors rather than big-box retailers, where this kind of damage is more likely to be visible.
These advice should aid you in identifying and treating any problems that may exist with your succulents. For you to always bring home a plant that can be your companion for years to come, we’ll be showing you things to avoid when shopping for plants and succulents in our upcoming post!
What are the signs that my succulent is receiving too much light?
Do you ever wonder why a succulent doesn’t look as good as it did when you first bought it? If a succulent is otherwise healthy, light should be taken into account initially.
Insufficient lighting causes the leaves of succulent plants to become colorless. They may flatten or stretch as they transition from red, yellow, or orange to faded blue or green hues (etiolate). Conversely, when exposed to much sunlight, succulents may develop beige areas on their leaves or close their rosettes.
Don’t simply glance down at the nursery; look up as well. Give your goods accustomed sun intensity when you bring them home. They might astound you when they settle in and the seasons change. It’s realistic to anticipate that they will look much better after having time and space to spread their roots.
How much light per day do succulents need?
Although this varies depending on the type of succulent, on average your succulents should receive six to eight hours of direct sunlight daily. Although succulents that have previously been kept in darker surroundings will need to be introduced to sunlight gradually in order to prevent burns, most succulents thrive in direct or largely direct sunshine.
For the majority of succulents, shade does not necessarily spell death. In fact, a lot of succulents may endure for a long time in the shadow or with only indirect light. Without sufficient lighting, succulents will deteriorate and fail to grow, though. Even if someone can withstand a circumstance, it doesn’t necessarily mean that it’s good for them.
How much sunlight can succulents withstand?
Since succulents come in a wide range of hues, forms, and sizes, their requirements and ideal environments will also vary. While some people thrive indoors, others favor the chilly temperature of the mountains. It’s crucial to understand the many types of succulents and their various needs before selecting how to best care for your succulents.
Succulents require various quantities of sunshine, depending on their color, species, and native environment. Succulents often benefit from 6 to 8 hours of sunlight per day. However, if succulents receive too much direct sunshine, they may develop brown blotches or even perish, especially when they are first planted.

How much natural light does a succulent need?
Depending on the species, succulents require vastly different amounts of light. Others, like cacti and some desert plants, require many hours of bright, direct sunlight each day. Some succulents, like zz plants and snake plants, can survive in low light environments. Knowing what kind of succulent you have can help you determine how much light it needs.
Direct Light
Direct light occurs when the sun’s rays pass through the window and directly hit your plant. Direct-light succulents should be placed in front of a south or west-facing window, where they will ideally receive six to seven hours of sunlight each day (although this can vary depending on your variety). Desert cactus, echeveria, sempervivum, jade, aloe, aeonium, senecio, agave, sedum, hoya, and other succulents need direct sunlight.
Because it is still being filtered through a window, direct sunlight indoors is not as powerful as direct sunshine outside. This only really matters if you want to relocate your indoor succulents outdoors for any length of time, as the sudden change in sun exposure might damage your plant’s leaves. Make sure to gently transition the plants to outdoor direct sunshine by starting with largely indirect light for a few weeks.
Indirect Light
Before reaching the plant’s leaves, the sun’s rays must pass through a filter, thereby creating indirect light. Even if the light is indirect, the area is still very bright. Indirect light is ideal for many different succulent species, including the haworthia, holiday cacti, snake plants, zz plants, string of hearts, rhipsalis, gasteria, kalanchoe, and peperomia.
Low Light
Succulents come in many varieties, and many can endure low light. Here, the word “tolerate” makes a crucial distinction. Although some plants can survive or endure lower light levels, most plants thrive in strong, indirect light when planted inside. You could observe that low light-grown succulents grow more slowly or have a leggier appearance than those grown in indirect light. Low light typically refers to plants that are placed at least a few feet away from a window and that do not have direct sunlight or bright filtered light shining on their leaves. Snake plants, zz plants, kalanchoe, mistletoe cacti, string of hearts, holiday cacti, fishbone cacti, and other succulents can all withstand low light levels.
How can I tell whether my succulent is content?
Firmness. Your succulent is hydrated when it is healthy, which means it doesn’t need water because water has been absorbed and stored in all of its cells. When you touch your plants, they should feel firm, which indicates that your watering strategy is effective.
What does a succulent that isn’t healthy look like?
On its leaves, a sick succulent will display the following indicators: leaves that are turning brown, orange, or yellow. leaves with dead leaf patches along the border. perforations in the leaves.
How long should succulents be kept in a grow light?
The temperature drops and the leaves begin to change as winter draws near. You must now bring your succulents inside to protect them from the harm that freezing can do.
Your house can provide your succulents the perfect temperature, but what about the light? Have you given this aspect any thought? If grow lights are to be used, how long should they be on for succulents?
If you want your succulents to flourish, you need to find the answers to these crucial questions. These and other inquiries will be addressed in this essay. There is a lot to learn, so let’s get going.
Whens The Appropriate Time to Bring in Succulents?
Some succulents, such hardy sedums and sempervivum, can survive year-round outside (even through the freezing winter days). However, when exposed to severely cold temperatures, the majority of other succulents suffer damage. Therefore, it is crucial that you bring your succulent indoors once winter arrives.
Examine the plant first, then take off any dead leaves and foliage as well as any insects you uncover. Clean the pans properly as well. When the outside temperature has dipped to about 40’S, or about 5oC, it is preferable to bring in your succulents. Your home’s temperature will be better suited for your delicate succulents, but you may need to change your watering routine because the plants will use less water indoors.
However, lighting is the most difficulty. Yes, some succulents may be content and able to thrive in your indoor illumination, but many will require more than that to survive. As you are already aware, photosynthesis, which produces the energy needed for growth and reproduction, depends on light. But without enough light, your plants will swell, become etiolated, and in extreme situations, they could even perish. So, if you see the succulents extending, that can mean they aren’t getting enough light.
Do Succulents Require Grow Lights To Survive?
It is not required. Your succulents are more likely to survive the winter months if there is a window where they may receive enough light throughout the day. But because the days are shorter in the winter, there won’t be as much light as there would have been in the summer.
It just takes a short while for succulents to start stretching out and losing their compact shape and vibrant colors if they don’t receive enough light. They might still be alive and healthy, but not as well as they would be in sufficient light. Winter’s shorter days frequently cause succulents to stretch, so you must find a means to adequately light your succulent so that the shorter days don’t impair the amount of light provided.
Grow lights hold the key to the solution to this. Your plant will remain vibrant and compact as a result. Additionally, it helps bring extra bright light throughout the day. Succulents housed indoors for multiple winters without the help of a grow lamp have occasionally survived without harm. However, when spring approaches, many of these succulents get more elongated. Many people frequently prune them back before planting the succulents in the ground. However, you might choose to buy a grow light to stop the stretching.
How Long Should Succulents Be Under Grow Lights?
There is a growing season and a dormant season for succulents. Since all succulents go dormant in the winter, they will need less light when kept outside, but they can tolerate as much light as possible indoors.
When grown inside, succulent plants won’t experience real dormancy until a shift in light and temperature is made to force it. Succulents need at least six hours of sunlight each day to survive, but they also need darkness every day to sustain a healthy development cycle.
You can put succulents under grow lights for roughly twelve to fourteen hours, which is the answer to the question of how long they should be. This indicates that the grow lights simulate natural sunshine in addition to a few more hours. A timer can be used to keep track of how much time has passed. It’s vital to buy a grow light with minimal heat output because some excessively hot lights will burn your plant.
What Grow Lights Should I Purchase?
In this session, numerous other queries are posed. There are several pertinent considerations, such as what type of grow light should be used, how much grow light is required, what hue of light should be acquired, and how far the light should be from the succulents. Here are some things to think about in relation to this:
What kind of light should I buy? A fluorescent light (CFLs) or a bulb (T5/T8 bulbs) is the best type of lighting to employ.
Which grow light color should be purchased? The greatest option is a daylight spectrum (especially one with a color temperature of 6500K)
How far apart should the succulent and the grow light be kept? A: The fluorescent light and the succulent should be separated by roughly 6 to 12 inches (but only if you are using a fluorescent bulb)
How many lights ought to be purchased? A: The quantity of plants will determine this. The more plants, the more grow lights are required.
The aforementioned advice was compiled based on effectiveness and cost. Nevertheless, there are other, more expensive choices to take into account, some of which are even more successful than those mentioned. Given their availability and efficiency, fluorescent grow lights are a good choice to take into account.
Regarding the color of light to be utilized and the recommended number of lights, the answers to the questions are the most ambiguous. Red and blue lights are the two most often used colors of light. The most natural light is provided by blue lights, which have a daylight temperature of 6500K. Also keep in mind that a 3000K bulb is the ideal choice for growing succulents properly under grow lights.
It’s typically advised to receive as much light as you can when it comes to the amount of light required. Additionally, shining this light directly on your succulent is a smart idea; but, in limited places, this might not be practical. However, the general concept is that you should use a light that covers a space of 1 foot by 4 feet if you have plants in that area. Grow lights can be purchased locally or online.
Wrap Up
In a well-lit interior environment, your plants can survive without a grow light, but one is still necessary because it ensures that they receive enough light for healthy growth and development. How long should succulents be kept under grow lights is just one of the numerous queries that come up with them.

What is causing my succulents to stretch?
When they don’t receive enough sunshine, succulents swell out. The succulent will first begin to turn and bend in the direction of the light source.
As it grows, the leaves will spread farther apart, making the plant taller.
The leaves are often smaller and paler in color than usual. The succulent will typically turn green or lose the strength of its original color when it is not exposed to sunshine.
This Echeveria ‘Lola’ is beginning to bend toward the light, and it isn’t quite as colorful as it was when I took the photo for the post about top dressings.
The majority of the time, this will occur when succulents are cultivated indoors, but it can also occur outside when succulents are exposed to too much shadow.
