Succulents in a pot – when should they be given extra light?
Succulents in a pot – when should they be given extra light?
Was your succulent collection impressive just a short time ago? Now it’s a pathetic specter of its former glory? You’re not alone in this frustration. Most beginner growers make the same mistake – they underestimate the light needs of their plants. Looking on Instagram or Pinterest, we see beautiful compositions of succulents with vibrant colors. Meanwhile, our plants look as if someone had squeezed all the life out of them.
What’s the problem? The answer lies in one word: light. But not just any light – succulents require a lot of light energy. This might be surprising, because they come from deserts, so they should be hardy. Exactly! The desert means intense sun for 10-12 hours a day, year-round. In Poland? In winter, we’re lucky if the sun shines for 6 hours. Add to that cloud cover, smog, and the fact that most of us live in apartment buildings… The result? Succulents are no longer succulents. Instead of juicy, fleshy leaves, we have thin, pale plants. Instead of a compact rosette, we have long, twisted stems. It’s not a disease – it’s a desperate attempt to reach the light. Can this be remedied? Of course! Supplementing light isn’t a whim of perfectionists, but a necessity..
Why do potted succulents need a lot of light?
Succulents primarily originate from regions with intense sunlight, where ideal light conditions prevail for most of the year. These remarkable plants have evolved special adaptations that allow them to survive in the harsh desert conditions. However, these adaptations require a sufficient amount of light to function properly. The photosynthesis process in succulents is slightly different from that of other plants. Most of them utilize the Crassulacean Acid Metabolism (CAM) mechanism, which allows them to open their stomata primarily at night. Nevertheless, intense daylight remains essential for this process to proceed properly. Light deficiency leads to a number of health problems in succulents. Plants become susceptible to fungal diseases, and their root systems weaken significantly. Furthermore, their resistance to pests and temperature fluctuations decreases.
Succulents are true sun lovers – they can’t live without it! In their natural habitat, they receive sunlight almost all day long, while in Polish apartments, the light is much weaker and shorter. This difference explains why our plants often don’t resemble their wild cousins. Evolution has endowed succulents with thick, waxy cuticles on their leaves, which protect against excessive water loss. However, these same structures require strong light to properly regulate the plant’s vital processes. In low light, the cuticles thin, causing the plant to lose its characteristic hardiness. Many species also possess special pigments, such as anthocyanins, which give them a reddish or purple tint. These pigments act as a natural UV filter, but are only produced under appropriate light intensity. Even succulents that tolerate less light, like haworthias, require significantly more light energy than typical houseplants. Their natural habitats are semi-shaded places, but still in a desert climate with very high sunlight.
Where should you place succulents in a pot so they grow well?
Choosing the right location for your succulents in your home is fundamental to their health. South-facing windows are the best option, providing the most natural light throughout the day. However, not all homes have this option, so it’s worth considering alternative locations. East-facing windows are the second best option, providing gentle morning sun. West-facing windows, on the other hand, can be too intense during summer afternoons. North-facing windows rarely provide enough light for most succulent species. It’s also important to avoid locations with drafts and rapid temperature changes. Succulents prefer stable conditions that allow them to thrive.
Additionally, remember to rotate the pots regularly to ensure all parts of the plant receive even light. The distance from the window plays a key role in the amount of light reaching the plants. Light intensity drops by half at just 50 cm from the window, and a meter from the window only provides 25% of the original light intensity. Therefore, succulents should be placed as close to the light source as possible. Curtains and drapes can block up to 70% of sunlight. If privacy is important, it’s better to choose semi-transparent materials or place plants in front of them. Dirty windows also significantly reduce the amount of light reaching them, so it’s worth cleaning them regularly.
The height of the windowsill is important for young plants, which can be shaded by larger specimens. It’s a good idea to create “steps” using saucers of varying heights, creating a sort of succulent gallery. This way, each plant receives an optimal amount of light. Moving plants seasonally may be necessary. In summer, some succulents may require light protection from the midday heat, while in winter, they should be moved as close to the windows as possible. This “nomadic” lifestyle is natural for them. The microclimate near a window differs significantly from the rest of the room. In winter, the temperature near the window can be a few degrees lower, while in summer, it can be higher. Succulents generally tolerate these fluctuations better than other houseplants, but it’s worth monitoring them.
However, if your apartment doesn’t offer enough light, there’s an effective way to make succulents grow almost anywhere—even away from a window. Simply use special LED grow lights. They emit light of the right intensity and spectrum to support photosynthesis. With them, you can place your succulents on a shelf, in a corner of a room, or even in a windowless bathroom—as long as they receive regular light for a few hours a day. This solution not only protects the plants from stretching and weakening, but also allows you to create green arrangements anywhere in the house.
Why do succulents in pots lose their color and shape?
Loss of characteristic color and shape is the most common problem faced by succulent owners. The main cause of these changes is insufficient light, which affects the production of pigments responsible for leaf color. Without adequate lighting, plants cannot produce anthocyanins and carotenoids. The process of shoot elongation, called etiolation, is a natural plant response to a lack of light. Succulents attempt to get closer to the light source, leading to a loss of compactness. At the same time, leaves become thinner and more delicate than in their natural environment. A change in color from intense green to pale green or yellowish signals serious problems with photosynthesis.
The plant is unable to process light energy properly, weakening its entire structure. As a result, succulents become less resistant to disease and pests. Internodal spaces elongate dramatically, forming characteristic “sticks” instead of compact rosettes. New leaves grow at greater distances, making the plant resemble a caricature of its original form. This process is virtually irreversible – etiolated sections will never regain their natural compactness. The consistency of the leaves changes from fleshy to rubbery or even soft. They lose their natural elasticity, becoming susceptible to mechanical damage. Often, a light touch is enough for a leaf to fall off or be permanently damaged. Some species respond to light deficiency by closing their rosettes or “huddling” together. This is a defense mechanism intended to protect the most delicate parts from further damage. Unfortunately, this further impedes light access to the plant.
Is it worth investing in a grow lamp for succulents?
Investing in succulent lighting is a decision that can significantly improve the health of our plants, especially during Polish autumn and winter, when the days are short and the sun rarely shines through our windows. Supplemental lighting becomes invaluable support for the health of succulents. The benefits of supplemental lighting are visible after just a few weeks of use. Plants regain their vibrant colors, and their habit becomes more compact. Furthermore, their resistance to diseases and pests increases, which translates into reduced losses in the collection. The cost of purchasing and operating LED lamps is now very affordable. Modern technologies allow for significant energy savings while ensuring optimal lighting conditions.
It’s also worth remembering that a single lamp can support several or a dozen plants simultaneously. A typical LED lamp consumes around 20-50 watts, meaning low operating costs. Compared to the loss of valuable plants from your collection, this is a truly small investment. Furthermore, most lamps have a lifespan of around 50,000 hours. The psychological benefits of supplementary lighting are just as important as the financial ones. Instead of watching their beloved plants slowly deteriorate, growers can enjoy their healthy growth. This is especially important for those who consider growing succulents a way to relax and de-stress. Supplementary lighting also allows for experimentation with more demanding species that wouldn’t survive in the Polish climate without additional light. This opens up entirely new opportunities for growers to develop their passion.
Which lighting fixtures should I choose for succulents?
Choosing the right lamp for succulents requires considering several key parameters. The most important factors are the light output and spectrum, which should contain the right proportions of blue and red light. Full-spectrum LED lamps are currently the best option available on the market. These lamps contain not only blue and red diodes but also other additional colors, such as ultraviolet (UV) and infrared (IR), which have unique properties that impact plant growth. The lamp’s power should be adapted to the number and size of the plants being lit. For a small collection, a 20-50W lamp is sufficient, while larger collections require more powerful lighting. Proper placement of the light source, 20-30 cm from the plants, is also important. Lighting duration is another important aspect to consider. Succulents require approximately 12-14 hours of light per day, so it’s worth investing in an automatic timer. This will ensure your collection receives a constant dose of light even when you’re not at home.

When to start lighting succulents?
If you plan to grow succulents in darker areas of your home, where natural light is always scarce, lighting should be used year-round. In such cases, artificial lighting becomes the primary energy source for the plants, completely replacing sunlight. However, if we’re only talking about supplementing succulents in the fall/winter, this becomes necessary after summer. Then, the days shorten significantly, and the intensity of natural light decreases. Plants begin to show the first signs of light deficiency, which are easily noticeable. During this time, succulents practically stop growing without supplemental lighting. Instead, they enter a vegetative stage, which can last up to several months. It’s best to start supplementing the lighting gradually, increasing the lighting duration from 8 to 14 hours per day. A sudden change can be stressful for the plants, so it’s best to introduce changes slowly. Furthermore, observe the succulents’ reaction and adjust the light intensity accordingly..
Summary
Potted succulents – when should they be supplemented? The answer is simple: whenever natural light is insufficient to provide optimal growth conditions. In the Polish climate, supplemental lighting becomes especially necessary during the autumn and winter months, when days are short and sunlight is insufficient. Investing in appropriate lighting guarantees healthy and beautiful succulents year-round. Modern LED lamps are energy-efficient, safe, and highly effective. They help our plants retain their natural colors, compact form, and high disease resistance.
Moreover, if we plan to place succulents in places completely devoid of natural light – such as deep interior spaces, shelves, hallways, or bathrooms – we can still do this, provided we provide them with constant light for the appropriate number of hours per day. Year-round use of LED grow lights allows plants to enjoy growing in places where natural light doesn’t reach at all. Remember that proper lighting is not only a matter of aesthetics, but above all, the health of our plants. Succulents blessed with the right lighting conditions will reward us with many years of beautiful growth and a spectacular appearance.
