You are unable to undo the harm the light has done to your succulents, which is unfortunate. Any discolored patches you notice on your plant are permanent since plants cannot heal from sunburn the way humans can.
There are a few solutions for handling sunburned leaves, but there is no cure for sunburn. The initial step is to remove the plant’s damaged areas. You might be able to grow new succulents from the damaged leaves since many succulents can be propagated from leaf cuttings.
Allowing the plant to grow is another choice. The old burned leaves on your succulent will ultimately shrivel up and fall off as it grows and develops new leaves. If you don’t have to get rid of the unattractive leaves right away, you can just let nature take its course. The plant will eventually produce enough new growth for the sunburned areas to eventually fall off and be completely covered.
How can a sunburned succulent be revived?
Succulents that get sunburned can’t use their leaves to absorb enough water and nutrients.
Replanting sunburned succulents in a shaded area and misting the plant with cool water to keep it hydrated are effective treatments for sunburn.
To assist your succulent maintain moisture, apply some mulch around the base if you see any wilting or drooping leaves.
You can put your succulent back outside in the sun as long as it is in a shady area and the sunburn has not resulted in any drooping or withering leaves.
Make sure your succulent receives enough water and is protected from direct sunlight by keeping an eye on it. You can put your plant back in a sunny location once all sunburn symptoms have vanished.
Additionally, check that your pot drains properly because a succulent’s sunburn may get worse if there is too much water left in the pot.
To make sure your succulent is getting all the nutrients it requires, you may also sprinkle an organic fertilizer once a month.
These plants must receive all the vitamins and minerals they require in order to start producing healthy new cells once more.
Basically, you want to do everything that can relieve this plant’s sunburn!
Do I need to remove the sun-damaged succulent leaves?
It would be better to cut off any leaves on your succulent plant that are 70 to 80 percent burnt. This is due to the fact that they are no longer able to contribute anything and are instead merely sucking nutrients from the rest of the plant.
However, since the healthy tissue may still produce nourishment for the plant, leaves that are still primarily green can stay on the plant.
When leaves get brown and black patches, they won’t get better. Simply use a sanitized knife or a pair of scissors to snip them off.
You may even be able to use the damaged leaves to grow new plants. The ability to frequently generate new plants through leaf cuttings is one of the main characteristics of succulents. This might be a choice if the leaf has sufficient healthy tissue.
What does a succulent look like when it is sunburned?
Succulents quickly begin to display signs of stress from excessive heat or intense sunlight.
Succulents frequently “blush” or change color when they are receiving enough sunlight. What a lovely transformation to witness!
However, if they begin to receive excessive sunlight, the leaves will actually burn. The succulent leaves may start to show white or pale areas. This harm cannot be undone.
As an alternative, make an effort to relocate your plant to a location with less intense sunlight and wait for new leaves to emerge. It is optional to remove damaged leaves if there are just one or two of them.
The leaves may truly turn dry and black in rare circumstances. The margins of the leaves will first turn black, and it will be dry and crispy (in contrast to blackening from rot which starts in the middle of the plant and is wet and mushy).
Once more, this injury won’t go away until the leaf totally withers and new leaves emerge.
A succulent in the shade may start to turn a golden or yellow tint if it is still quite hot outside. Instead of turning entirely white, as would happen with sunburn, the succulent instead appears warmer or more yellow than usual.
If the succulent is transferred to a colder setting, this usually disappears or the succulent returns to its normal hue.
I can keep succulents alive very well sometimes, but not always.
I recently relocated to Arizona from Utah. Growing succulents can be challenging for a variety of reasons, including relocation. You must pay close attention to how much heat and sunlight each area of your garden receives.
Although it’s a little humiliating, I’m going to show you what my garden looked like when it received excessive sunlight and heat in the video below.
Hopefully, this example will show you what to watch out for so that your garden doesn’t turn out like mine did.
Do sun-damaged leaves heal?
A scorching can result from throwing your plant directly into the sun, especially if it doesn’t flourish in direct sunlight.
Your plants can become sunburned in just a few hours, and once the damage has been done there isn’t much you can do.
How to know if your plants are sunburnt?
It’s actually fairly simple to determine whether the leaves on your plants are sunburned. Like human skin, the leaves of your plants will turn red when exposed to too much sunlight, but if the damage is severe, they will turn yellow or white instead of red.
The color of the leaves can also change if the plant receives too much water or not enough light, but sunburn is typically the culprit. Where the light is shining, on the top of the plant, you can see this in the leaves. The bottom leaves won’t alter as much because they are closer to the soil and receive some shade.
How to prevent sunburn in your plants
The most important thing to understand is what your plant needs and the environments it prefers. If they won’t be able to endure it, keep them out of the harsh sunshine.
While some plants, like peace lilies, prefer low-light circumstances, others, like succulents, adore direct sunlight and will thrive outdoors in the summer sun, are more likely to burn if transferred to a sunny place.
It doesn’t mean you can’t move your plants to a place where they get a little more sunlight or even move them outside when the weather warms up; you simply need to do it gradually.
Make the move for a plant from a location like the toilet to the sun gradually rather than hurriedly. Start by transferring it to a shaded area or setting it up in the morning for a few hours before returning it to the shade. After that, over a few weeks, gradually increase the amount of sunlight your plant receives. Always opt for less sun than too much, especially if your plant doesn’t like intense, direct sunshine, as this is the best course of action.
What can I do if my plant is sunburnt?
Unfortunately, a plant’s leaves won’t become green again once they’ve been burned by the sun. The best course of action is to remove the sun-damaged leaves and relocate the plant to a location with ideal lighting for its variety.
You should be able to prevent your plants from receiving too much sun if you are careful with them.
Can you save a plant that has sunburn?
Plant sunscald damage is simple to avoid, but there is no treatment available. Once a leaf is broken, there is nothing you can do but nurture the plant until new, stronger leaves can be produced. In order to encourage the growth of sun-resistant leaves and guard against plant sunburn damage, slower acclimatization to harsh sun, also known as hardening off, is essential.
Use a sunshade to limit the UV exposure for plants that are already ill. As they get more resilient, gradually increase the amount of time they spend each day without the sunshade. Your plant should be prepared for the sun after roughly two weeks of this approach. As plants struggle to recuperate, be sure to properly water and feed them with sunscald; they’ll need all the help they can get.
What should you do with a sun-damaged plant?
Unfortunately, your plant won’t eventually develop a tan or be able to treat its sunburn using aloe vera. “Steinkopf advises cutting off the damaged leaves or, if possible, trimming them if your plant has been burned. “They won’t recover or turn green once more.
Then relocate your plant to a less-lit place, preferring filtered light to direct sunlight.
Embrace it with your most sincere apologies before returning to proper care.
The best course of action is to promote growth going forward and absorb lessons from your errors. Just keep in mind the next time that plants too require protection from the sun and they will forgive you.
What occurs when succulents receive too much sunlight?
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!
How can a succulent be revived?
Yes, I am aware that it seems illogical to remove extra water from the soil, but bear with me. This is the justification. Too much water has already put the succulent under stress, and exposure to sunlight makes matters worse. Direct sunlight is a big no because most succulents require brilliant indirect light.
Place the succulent that has been overwatered somewhere dry and bright, but out of direct sunshine.
2. Permit the roots to breathe.
Cut off any brown or black roots as they are already rotting. Dig the succulent out of the ground and remove any excess soil that has become stuck to the roots. Place the plant on a mesh or other strainer until the roots have had two to three days to air dry. Replant the roots in the pot once they have dried completely.
Remove the entire root system and any puckered, spotty, black, or brown stems if the roots are entirely rotted. The succulent stem can be buried in the ground for propagation.
Keep the overwatered succulent on a mesh screen or other strainer until the roots have had two to three days to air dry.
3. Modify the ground
You might not need to entirely alter your succulent if it is already rooted in homemade or commercial succulent soil. Algae (green living matter) typically grows on soil that is too wet. If so, it is your responsibility to remove all of the top soil from the area around your plants and replace it with new succulent soil.
Can Succulents Get Too Much Sun?
Photosynthesis requires sunlight. All plants, even succulents, require the process of photosynthesis, which is pronounced FO-to-SIN-thuh-sis. The scorched tissue on a succulent’s leaves, however, prevents it from photosynthesis. Your succulents may suffer permanent damage or possibly die from too much sun.
Succulents do adore the sun, and many of them can tolerate some direct sunlight during the day. Additionally, they thrive in warm conditions of 80 degrees (27C) or above. However, if you combine the two—direct sun on a day that is at least 80 degrees—your succulents could experience problems. Just as you would feel OK sitting in the sun for an hour at 21 degrees Celsius (70), but you’d have to seek cover after 15 minutes at 80, (27C).
Your skin or a succulent will be burned by UV rays and the strength of the sun, not by heat. You both have higher core temperatures and water loss as a result of the increased heat, making you both more vulnerable to physical harm, including sunburn.
Early Signs of Succulent Sunburn
A succulent will become stressed if it is exposed to too much sunlight. The succulent may be able to adjust to the additional heat and light by creating vibrantly colored pigments if this stress is introduced to it gradually. It will get sunburned though if the extra light is too much all at once. On the leaves, discolored areas will start to appear. These blotches typically cover the top of the leaf and are light beige, tan, brown, or black in color. They have a rough roughness in contrast to the leaf’s smoothness. These blotches are made out of sunburned leaf skin tissue.
Scars appear on a burnt succulent. Where they develop, the dark, discolored areas on the leaves are persistent. A closer inspection of the image above reveals that some of the leaves still have a faint beige hue at the base of the black. The texture is still smooth, and the leaf almost seems to have a gloss. This is the initial indication of a succulent sunburn, which is still treatable at that point. The results are not as unattractive, and the leaf will recover quickly if you catch it at that point and provide shade right away before the full scarring happens.
The Echeveria seen above was exposed to the sun until the actual succulent sunburn’s dark patches appeared. Despite considerable damage and scarring, the plant is still in good general health. Most of the harm is aesthetic. The scorched leaves are still standing. In the green parts, they can still photosynthesise. Additionally, each can still communicate nutrients and moisture through its cells. The burned leaves will ultimately fall off when the plant naturally sheds the older foliage as it grows outward from the center over time. As an alternative, you could take off the damaged leaves right away for further growth. The likelihood that the leaf will root and grow a new plant offspring is unaffected by this level of sunburn.
Prompt Action is ImportantSunburn Progresses
It’s crucial to act quickly when succulent sunburn first appears. When your succulent starts to burn, don’t keep it in the same spot—it will continue to burn and get worse. Only a few leaves would be damaged on the Echeveria in the picture above if it had been quickly relocated into some shade, but the plant would still be in good health. More than half of the leaves in the second photograph have severe scarring and are no longer able to perform photosynthesis. However, you can tell that the plant still has a lot of energy to devote to healing or reproduction from how vibrant the green leaves are. The scarred leaves are severely wrinkled and starting to crumble by the third photograph. You’ll also see that the plant’s vitality and health are declining as the green leaves turn more grey.
Take steps to safeguard your succulents if you see them starting to burn; otherwise, the damage will get worse.
Individual plants and various species of succulents will react differently to intense heat and sunlight. The majority of the leaves on the Echeveria on the front left and right both have significant sunburn. The Echeveria may outgrow its scarred leaves if the container is placed into greater shade, or they can be utilized to generate other plants. There is a lot of carotenoid production from the Sempervivum in the middle. Carotenoid (Kair-AH-ten-oid) is a yellow, red, or orange fat that has entirely lost all of its color as it tries to adapt to the environment. And the burning of the leaves has only begun. This plant will quickly regreen if provided prompt shade. Not even stressed is the Echeveria on the back right.
Sun Damaged Succulents
Aloe and agave are two succulents that can withstand the intense summer sun. As the summer temperatures rise, other types, such as Sempervivum and Aeonium, are more likely to struggle. But it’s crucial to maintain a close eye on your entire collection.
This Sempervivum has been severely burned by succulent sunburn, and many of the leaves are dead. However, some of the puppies and healthy leaves are still present. The baby succulents that emerge at the base are known as succulent pups, and they still seem to be in good health. The puppies don’t appear to have any scars, despite the fact that their hue indicates that they are plainly under stress. If shade is promptly given, they should joyfully take root, develop, and mature, and it is likely that the mother plant will live to propagate further. The Echeveria is under some stress, although it has not yet been harmed.
Succulent Sunburn Can Be Deadly
Tragically, sunburn can be fatal. I think this Sempervivum would have died completely if it had spent even one more day in the direct light. It will fight valiantly to survive as it is. The center’s newest leaves do appear to be healthy. The majority of the damaged leaves have collapsed, rendering them incapable of photosynthesizing or transmitting moisture or nutrients. The plant might be able to survive on some of its lower, still-green leaves while it grows new top growth. But if the destruction had continued for another day, it would have been impossible.
Succulents require varying amounts of sunshine. But be cautious when shifting even a succulent that enjoys sunlight quickly from a shaded growing area to greater sunlight. It is well worth the time to let them gradually get used to the proper level of light. Read my post on etiolated succulents and the cues they provide regarding light exposure for guidance on determining when your succulents need more or less light.
Once you’ve chosen the ideal location for your succulent, you must keep an eye on it all year long. A plant that enjoys full sun in the early spring may suffer in the same location in the summer. With some of the aforementioned photographs, that is what took place. I wish I had a better understanding of the science and mechanisms underlying succulent sunburn so I could explain it to you more clearly. For now, suffice it to say that when temperatures rise, the sun’s intensity rises as well. And this could end up killing your succulent plants.
Protect Your Succulent from Sunburn Like the Pros Do
The easiest option to shield your succulents from harm caused by excessive heat and/or sunlight is to use shade fabric.
Shade cloth is a unique material made to shield plants from sun harm while still allowing some light to get through. In addition to blocking a substantial amount of UV rays, it guards against heat buildup in the tissues of the plants. To keep their plants looking their best for sales, professional succulent growers generally grow their plants under shade cloth. While this method definitely works to increase sales, a careless succulent grower can take a succulent that has been well-sheltered and place it in the sun, which would cause the plant to become fried or collapse. Succulents should always be exposed to increased light gradually. And suppose that shade cloth was heavily used to protect the plant you just bought. Give it plenty of bright shade in your garden before easing it into more light. Every two to three days, add just a half-hour more light, and pay close attention to the plant for signals that it needs more or less light.
Although I don’t cover all of my succulents with shade cloth constantly throughout the year, many people do. I would rather see them become more resistant to environmental hardship. But I do set up shade cloth structures for them in the summer heat. And I wholeheartedly urge anyone who gardens in scorching temperatures or in arid regions to utilize shade cloth all year long. Use shade cloth if you’re not sure if your succulents require more sun. It is the simplest approach to match succulents’ year-round requirement for sunlight with their protection from sun harm. Additionally, it gives you a lot more alternatives for how to expose different types of plants to light in your garden.
Shade fabric is available in a variety of hues and densities, ranging from 5 to 95 percent shade. The density should not be confused with the colors. While some black shade fabric only blocks 40% of the sun, some white shade cloth blocks 60% of it. Because they are cooler for my plants and the colors make more sense to me in the garden, I like white, pale beige, or tan. However, every shade cloth blocks UV radiation and offers shade that is 10 to 15 degrees cooler than the temperature in direct sunlight. You should choose your shade cloth based on density before deciding on a color that you like. Depending on your environment, choose a shade cloth that offers at least 35 percent shade and up to 70 percent shade. In hotter regions, use a higher density.
In addition to being extremely durable against UV rays, water, and wind damage, shade cloth also lasts for many years of continuous usage.
