If you’re a succulent lover, you know that these unique and drought-tolerant plants are a great addition to any home or garden. But how much sun do succulents actually need? The answer may surprise you.
In general, succulents need plenty of sun to thrive. In fact, most species of succulents prefer bright, indirect lighting and will do best when placed in a location that gets at least 6 hours of indirect sun per day. This means that a south- or west-facing window is often the ideal spot for your succulents.
But what about those species of succulents that are labeled as “full sun” plants? While it’s true that some succulents can handle direct sun, it’s important to remember that even these sun-loving species need a little bit of shade. Too much direct sun can actually cause your succulents to become sunburned, leading to unsightly brown patches on the leaves.
So, how can you ensure that your succulents are getting the right amount of sun? Here are a few tips:
Monitor your succulents regularly to see how they are responding to their lighting levels. If the leaves are starting to stretch or become discolored, it may be a sign that they are not getting enough sun.
Avoid placing your succulents in low-light areas, such as north-facing windows or dark corners of the room. These locations may not provide enough sun for your plants to thrive.
If you live in a climate with very hot, direct sun, consider providing your succulents with some shade during the hottest parts of the day. This can help prevent sunburn and keep your plants looking their best.
Overall, succulents are tough and adaptable plants, but they do need plenty of sun to thrive. By following these tips, you can ensure that your succulents get the sun they need to grow and flourish.
So, how much light DO succulents need?
Short answer is that the light that succulents need depends on a few things and not every succulent can handle the same amount of sun. Real helpful, huh?
Read on to find out what it looks like when succulents need more light.
Temperature Regulator
In addition to providing energy, sunlight also helps to regulate the temperature of the plant and keep it from overheating. Succulents are adapted to hot, dry environments, and they require plenty of sunlight to prevent them from getting too cold. When exposed to sunlight, the plant’s leaves and stem will absorb the heat, which helps to keep the plant warm and healthy.

How to Acclimate Your Succulents to Brighter, More Direct Light
When transitioning succulents from one light condition to another, it’s important to do so slowly to avoid shocking the plant. Here are some tips for acclimating your succulents to their ideal brightness conditions:
Gradually increase light exposure: Start by placing the succulents in a spot with indirect light and gradually move it to a spot with more direct light over the course of a week or two. This will give the succulents time to adjust to the change in brightness intensity.
Monitor for signs of stress: Keep an eye out for signs of stress in your succulents, such as yellowing leaves or wilting. If you notice any of these signs, move the plant back to a spot with less light.
Provide shade: If you’re moving a plant from a low light environment to a high light environment, provide the plant with some shade during the transition period. This will help prevent sunburn and other damage caused by too much direct sunlight.
Give the succulents time: It can take several weeks or even months for a plant to fully acclimate to its new light conditions. Be patient and give your succulents the time they need to adjust.
Keep an eye on the humidity: Transitioning to a new light environment can also affect the humidity in the room. Keep an eye on the humidity levels and adjust the humidity accordingly to prevent any issues.
By following these tips, you can help your succulents make a smooth transition to their ideal brightness conditions and keep them healthy and happy for years to come.
Aim for about 6 hours of sunlight every day to start
Six hours would be the median amount of time your succulents should be getting direct sun in order to stay healthy. Some like more, some like less. Get to know your plants and observe them to learn what kind of sun requirements they have.
Succulents need lots of light for photosynthesis whether it is from the sun or from supplemental grow lights. Photosynthesis is the process by which plants convert sunlight into energy.
Learning how much sun to give your succulents is a process of trial and error. Do observe your succulents and learn the signs that they’re not getting enough sun. As soon as you see one of those signs, adjust the lighting situation by moving the succulent to a different location.
Another thing to observe and learn is the sun exposure of different parts of your yard or house so you have an idea of where to move your succulents when they’re telling you they need more or less sun.
| Light Level | Description | Suitable for |
|---|---|---|
| Full sun | Direct sunlight for 6 or more hours per day | Succulents that love heat and sun, such as Agave, Aloe, and Echeveria 'Afterglow' |
| Partial sun | Direct sunlight for 4-6 hours per day, or bright, indirect sunlight for most of the day | Succulents that can tolerate some sun, such as Haworthia, Kalanchoe, and Sedum |
| Filtered sun | Bright, indirect sunlight for a few hours a day, or dappled sunlight under a tree | Succulents that prefer bright but indirect light, such as Gasteria, Sansevieria, and Zebra plant (Haworthiopsis attenuata) |
| Shade | No direct sunlight, or only a few hours of very early morning or late afternoon sun | Succulents that prefer shade or low light, such as Snake plant (Sansevieria trifasciata) and Crown of thorns (Euphorbia milii) |
Specific Light Needs For Some Succulents
While most succulents prefer bright, indirect light, the specific needs of your plants may vary depending on the type of succulent you have. Some succulents, like cacti, can tolerate more direct sunlight than others, while others, like aloe vera, prefer less light. To determine the specific sunlight needs of your succulents, do some research on the specific type of plant you have or consult a succulent expert.
What exactly IS bright, indirect light?
Bright, indirect sun refers to light that is bright and intense, but not direct or harsh. It is typically found in locations that are near a window or other source of natural light, but that are not directly in the sun’s rays.
For example, a room with large windows that face east or west is often a good source of bright, indirect sun. The sun’s rays will be filtered through the window glass, providing plenty of sun without being too harsh or direct. Similarly, a location that is shaded from direct sun but still receives plenty of reflected light, such as a porch or patio, can also provide bright, indirect sun.
Bright, indirect sun is ideal for most plants, including succulents, as it provides the intensity of light needed for photosynthesis without the risk of sunburn or other damage. If you’re not sure if a location has bright, indirect sun, you can try the “shadow test”: if your shadow is shorter than you are tall, the location is receiving direct sun; if your shadow is taller than you are, it is receiving indirect light.
Signs That Your Succulents Aren't Getting Enough Light
When a succulent doesn’t get enough sun, a few things can happen as a natural response to light deprivation. This is called etiolation. Below are the characteristics of an etiolated succulent.
It’s color will become less vibrant and more pale. (Reversible)
Leaves will bend downwards to increase the amount of surface area exposed to light. (Reversible)
The main stem will become leggy, elongate or curve in order to reach more light. You may have heard people refer to leggy succulents and this is what they mean by that. (NOT Reversible)
Pale Color
An etiolated succulent is also often paler than its well lit counterpart. This is because less light means less photosynthesis and less chlorophyll production which produces the deep coloring.
This can be reversed by giving your succulent more light gradually so it doesn’t burn.
Leaves Bending
Leaves bending down or flattening is usually the first sign that a succulent is not getting enough light. This is especially noticeable in rosette shaped succulents like echeveria or sempervivum. Their reaction is to increase the amount of exposed surface area in order to receive more light.
This can be reversed by giving your succulent more light by gradually moving it to a sunnier location or by using a grow light.
Stretching
Another way succulents show that they’re not getting enough light is by stretching. Some succulents are naturally “leggy” so if you’re not sure, just look up the name of your succulent and you’ll be able to see what they should look like if given proper light conditions. When starved for light, succulent stems will elongate rapidly to reach a light source.
The stem grows faster than the plant can create new leaves, so there’s lots of extra space between leaf sets or nodes. This also allows more light to penetrate between the leaves. While all of this new, quick growth may look neat, the plant is weaker and unhealthy.
Stretching cannot be reversed so it is important to know what the first 2 signs look like in order to avoid the stretching.
Etiolated plants are not thriving. They are weaker than their appropriately lit counterparts because their energy is being used to search for a light source rather than grow as nature has intended. Their leaves are also smaller because they simply don’t have the energy to make bigger leaves.
Etiolated plants are thus, more susceptible to opportunistic bacterial and fungal diseases. They are also more susceptible to mealy bugs. Why? Mealy bugs LOVE new growth and etiolated plants have lots of that.
What is Etiolation?
Etiolation refers to the process of a succulent becoming leggy due to a lack of sun. This can occur when a succulent is grown in low sun conditions or when it is partially shaded.
As a succulent grows, it relies on the sun to produce energy through photosynthesis. When a succulent is not getting enough light, it will stretch and become leggy in an attempt to reach the light source. This can cause the succulent to become weak and prone to falling over.
Etiolation can also cause the succulent to produce fewer leaves and flowers, as it lacks the energy it needs to produce these structures. In severe cases, etiolation can even cause the succulent to die because it is structurally weak and more susceptible to disease.
To prevent etiolation, it is important to provide your succulents with adequate sun. This will allow them to grow compact, strong and healthy, producing plenty of leaves and flowers.
How To Fix A Leggy Succulent
Behead the leggy succulent and replant the top because it won’t shrink back down to normal size. If the lighting situation doesn’t improve, the new growth will continue to etiolate and further weaken the succulent.
Give it the appropriate amount of light for the new growth to come in compact.
To fix this, you can try moving your succulent to a location with more light. A south- or west-facing window is often a good choice, as these locations tend to receive plenty of bright, indirect sunlight.
Finally, you can also try fertilizing your succulent to encourage more compact growth as long as there’s enough light. Use a balanced, but dilute succulent fertilizer, and be sure to water your plant regularly to keep the soil evenly moist. With the right care, your succulent should start producing more compact, healthy growth in no time.
Want to learn how to fix your elongated succulents? It’s a common problem, but don’t worry, I’ve got some tips for you!
So, the reason your succulents are elongating is probably because they’re getting too much shade. This can cause them to grow taller and longer, with leaves spreading out and becoming lighter and smaller than usual. If they’re colorful, like orange, yellow, red, purple, or pink, they’ll need even more direct sunlight, which can be tough to provide indoors.
But don’t worry, you can start propagating your elongated succulents in four different ways: from well-rooted ones, stems, leaves, and the rosette on top.
First, cut off the top part of your succulent or rosette and plant the fresh cuttings directly into soil. But don’t water them for seven to ten days, and don’t expose them to direct sunlight right away. Give them time to stabilize and produce their own roots.
You can also propagate through their leaves by wiggling them from side to side until they snap from the stem. Air dry them for a few days and lay them flat on soil. Don’t expose them to direct sun at this time, or the leaves might dry out before the babies and roots come out.
Another way to propagate is from cut stems. Air dry them until the tips are calloused, then plant them into soil. It might take several weeks, but your patience will be rewarded by several babies growing out from the area where you plucked the leaves.
Lastly, you can propagate from well-rooted ones. Remove all the rosettes and leaves, and start propagating them. In a few months, you’ll have a bunch of new babies!
So there you have it, some tips to fix your elongated succulents and propagate them quickly. Give it a try and soon you’ll have a bunch of new succulent babies!
You might also be watering your succulents too much.
Etiolated succulents grow really fast. Could your watering habits be contributing to etiolation? If you have etiolated succulents, try holding back their water to slow the stretching.
Signs your succulents are getting TOO MUCH light
If your succulent gets too much sun, too quickly, it will burn. You’ll see rough, brown patches on the leaves which were previously beautiful and unblemished.
Sunburn on succulents is physical damage that can’t be reversed. You’ll just have to wait for it to grow out.
In the meantime, protect your succulent from further sun damage by putting it under an umbrella. Sun damaged succulents are more susceptible to pests and diseases because that tissue has become weakened.
While succulents are known for their ability to tolerate hot, dry conditions, they can still be damaged by too much sun. Most species of succulents prefer bright, indirect light and will do best when placed in a location that gets at least 6 hours of indirect sun per day.
However, it’s important to remember that even “full sun” succulents need a little bit of shade. Too much direct sun can cause the leaves to become sunburned, leading to unsightly brown patches on the plant. In extreme cases, too much sun can even cause the plant to die.
To prevent sunburn, it’s a good idea to provide your succulents with some shade during the hottest parts of the day, especially if you live in a climate with very hot, direct sun. This can help keep your plants looking their best and prevent damage to the leaves.
In general, it’s a good idea to monitor your succulents regularly to see how they are responding to their sun levels. If the leaves are starting to stretch or become discolored, it may be a sign that they are not getting enough sun. On the other hand, if the leaves are starting to look sunburned, it may be a sign that they are getting too much sun. By paying attention to your plants and providing them with the right amount of sun, you can help them thrive.

Bringing Out the Best in Your Succulents: Sun-Stressing 101
Have you ever seen succulents outside with bright, beautiful colors? This is because of something called sun-stressing. This is when a plant is exposed to a lot of sunlight and heat, which causes a special pigment called anthocyanin to activate. This pigment helps protect the plant from the sun’s harmful rays and makes it turn red or yellow. But, how can we do this safely for our succulents?
To start off, when putting your succulents outside, it’s best to put them in a bright spot but not in direct sunlight for a week or so. This will help them get used to the change. After that, you can move them into morning sunlight for a few hours a day for a few more days before finally putting them in full sun. You should start to see color in your succulents after a week or so. Remember, succulents like cacti and those that come from dry, hot places are best for this type of treatment.
It’s important to keep in mind that your succulents will need more water when they are outside because the sun and wind dry them out faster. But, too much water can also be bad for them. They are used to dry conditions.
Another thing to keep in mind is that as the weather gets cooler in the fall, your succulents might turn even more colorful. Just remember to bring them inside when the temperature drops below 45-50°F.
It’s important to keep an eye on your succulents while they are being sun-stressed. If the colors look washed out or the leaves have burns or look crispy, it means they are getting too much sun and should be moved to a shadier spot.
Overall, sun-stressing is a great way to bring out the best colors in your succulents but it’s important to do it safely by gradually moving them into the sun and keeping an eye on them.
Effects of Different Light Levels
Echeveria prolifica
I’m currently preparing to completely revamp my succulent fountain and trying to condense my collection as much as possible. One of my favorite succulents is Echeveria prolifica and one of the items on my to do list was to plant them in a wide planter so that they could throw out their pups with plenty of room to root.
While planting the Echeveria prolifica cuttings, I was pleasantly surprised to see how different they looked depending on the location and amount of sun they received.
Kalanchoe fedtschenkoi ‘Lavender Scallops’
What are some low light succulents?
• Jade plant (Crassula ovata) – Can tolerate some shade and only needs occasional watering. Will grow more slowly in low light.
• Snake plant (Sansevieria trifasciata) – One of the most tolerant succulents for low light. Rarely needs watering.
• ZZ plant (Zamioculcas zamiifolia) – Despite its name, ZZ plant is a succulent that thrives in low light and with minimal watering.
• Aloe vera – Can tolerate some shade but will grow more slowly. Only needs water when the soil is dry.
• Haworthia – Many haworthia species do well in low light. They resemble miniature aloe plants.
• Gasteria – Another aloe-like succulent suited to shade. Features unique warty leaf textures. Water when soil is dry.
