Succulents and cacti typically require between 10 and 14 hours of light every day.
However, there are several things that affect how much light you should provide! What kind of light is it? Is it man-made or natural? Is the light direct or indirect?
You should at the very least be aware of whether your succulent prefers full sun, full shade, or a combination of the two. If you’re unsure, you can presume the plant needs full sun. Cacti and succulents in general are!
Ever questioned why you couldn’t simply leave the lights on all the time? That would imply that it is constantly expanding, right?
Actually, not quite. Like people, plants also require rest. Particularly in the case of desert flora. They engage in CAM photosynthesis, a unique type of photosynthesis. They truly only produce plant food at night, unlike other plants. They would starve if the darkness didn’t exist.
How much light is required for an indoor cactus?
There may not be as much as you think to the brief response. The distinctive forms of spiny cactus were created to reduce the quantity of sunlight they get.
One of the causes of their spines, which are really highly modified leaves, is due to this. They would receive more desert sunlight if they were covered in leaves, which would lead them to lose too much of their valuable water.
Spiny cactus kept indoors should typically receive four hours per day of direct, strong sunlight. This means that kids should spend at least four hours each day in a room or close to a window that is highly lighted by natural light.
Holding your hand over a piece of plain white paper in the area where you intend to keep your cactus is a good way to gauge how bright the light is. A clear shadow indicates that the light is sufficient.
Can cacti live in the absence of sunlight?
The amount required will vary according on the species, thus your particular cactus may require more or less than this.
Avoid leaving your cactus in direct sunlight for extended periods of time since succulent plants thrive when they can absorb light gradually.
If you must leave it outside during the day, move it every hour or two from a shaded area into indirect sunlight and then back before dusk.
For your plant to grow inside, it needs at least four hours per day of direct sunlight.
During these times, natural light intensity is at its highest, allowing your indoor cactus plant to receive more exposure without jeopardising its health.
What amount of light does a little cactus require?
The majority of cacti species typically require four to six hours of sunlight per day to grow. These plants adore bright, sunny environments. Many other symptoms could appear in plants that don’t get enough light.
Etiolation/elongation may be the most typical symptom that your plants aren’t getting enough light. These are the stretches that plants make in order to reach more light. Even though it may appear to be a fantastic self-adaptation mechanism, etiolation results in weak stems and could cause poor growth.
If cacti plants are not exposed to enough light, they may also turn pale or go back to being green. On the other hand, plants that are exposed to enough light show off their genuine beauty by displaying a variety of brilliant colours.
Do house cacti require sunlight?
Nowadays, cacti and succulents are highly popular indoor plants, therefore taking good care of them is crucial. They occur in a wide variety of sizes and shapes, ranging from the small to the enormous. Because they share traits that enable them to endure in arid conditions, cacti and succulents belong to the same category.
The majority of succulents and cacti are endemic to desert environments. They will therefore thrive in conditions with lots of light, good drainage, hot temperatures, and little wetness. However, some cacti and succulents, like Schlumbergera, enjoy semi-shady and wet environments because that is their natural habitat.
The easiest way to take care of cacti and succulents is to try to mimic their natural environment. The essential factors you should take into account when taking care of your succulents and cacti are listed below.
Light, temperature and ventilation
It is advisable to arrange cacti and succulents in a bright area because they do best with good light sources. A place that faces south will get plenty of light. But be careful not to place them in direct sunlight since the strong light may cause the plants to turn yellow. The best kind of light for growing cacti and succulents depends on the species that you are using. For instance, forest-dwelling epiphytes like Rhipsalis require some shade, whereas an Echeveria requires strong light.
It is ideal to keep the plants cool at night, between 8 and 10 degrees Celsius, during the fall and winter. The plants will survive in high temperatures, but they require sufficient ventilation in the spring and summer.
Compost
Since Westland cacti and succulent potting mix has included girt and sand for the best drainage, it is a good compost to use. Additionally, it has the ideal quantity of nutrients for your succulents and cacti.
Watering and feeding
It’s a popular misperception that succulents and cacti just need a tiny bit of water. Although their leaves and stems can store water, allowing them to survive in dry environments, they will not grow in environments with little water. Your cactus or succulents’ ability to develop successfully depends on regular watering. Underwatering results in shrivelling while overwatering stunts growth.
Instead of using tap water to water plants, use lukewarm rainfall. This is because the minerals in tap water can settle on the leaves and accumulate in the soil. Additionally, minerals obstruct the plant’s access to vital nutrients.
Spring and summer
The plants need to be watered at least once a week during the growing season. Give the soil a good soak when watering, letting any extra water run away. Every time you water the compost, give it a little time to dry out.
Utilize Westland Cacti and Succulent Feed, a recommended recipe to use, to feed your plants once a month. They create more robust growth that is more resistant to disease and has superior flowering thanks to it. Simply take a 5ml quantity of the feed from the dosing chamber and mix it into 1 litre of water.
Autumn and winter
The plants enter a period of rest at this time. Reduce watering so that the potting mix dries out in between applications. The type of succulent and the environment it is in will determine how frequently it has to be watered. Winter-flowering cactus should be kept warm and watered frequently now, whereas desert-dwelling cacti don’t need to be watered. Cacti and succulents don’t need to be fed during this time.
Re-potting
The optimal time to repot cactus or succulents that are pot-bound is in the spring. To replant:
- Before carefully taking the plant from the pot, water it and let it drain. Use folded paper to shield your hands from the spikes.
- To avoid damaging the roots, remove the old soil from around them with a thin stick, like a chopstick.
- The new container, which has a slightly larger diameter, should be filled with potting soil before placing the plant inside of it.
- The remaining potting mix should be added to the pot and compacted.
- To stop the rotting of injured roots, stop watering for a few days.
The finest care for your succulents or cacti comes from maintaining these conditions. The most crucial thing to keep in mind when taking care of your plant is that you are trying to mimic its natural environment!
Does darkness help cacti grow?
Since it is challenging to measure, light is an amusing phenomenon. It is not as if you can offer your cactus plant 7 pounds of light every day, but if we were talking about water requirements, we could say that you need to pour one or two cups of water on the plant once or twice daily.
Simply put, that cannot happen. So how can we gauge how much light to provide your cacti?
Well, measuring the duration will give us the most accurate estimate. How much time each day should your cactus plant be exposed to light? Additionally, you must comprehend how much of each type of light there is, keeping in mind that both natural and artificial sunshine exists.
Thankfully, we are here to make things easier for you and make sure you take good care of your cactus. So let’s start with the fundamentals.
Between 10 and 14 hours of light are required by cacti and other succulents each day. Limit the amount of light your cactus plant receives each day to 14 hours. A plant may thrive with 12 hours of light every day on average.
Keep in mind that your plant requires rest as well, and providing it with more than 14 hours of light each day will not benefit it in any way. In truth, cacti plants require darkness in order to absorb carbon dioxide, which will be used throughout the day for photosynthesis.
Know Your Angles
Knowing which direction your house faces is one of the most important things you should do before you even go for the cactus plant.
You receive all that southern exposure if your home faces north or south, which is excellent. It will be a little bit more challenging if your home faces east or west because that light isn’t as intense or hot as the north-south light.
If you are fortunate enough to live in a house with a north or south exposure, be sure to observe the sun for several days to determine how many hours of sunlight you receive each day.
This will help you decide which kind of cacti to choose and what to stay away from. For some cacti, like the blue cactus, several hours of relentlessly scorching sunlight are typically necessary for growth.
Choose a darker variety of cactus plant if your home faces east or west, which means you receive less sunshine, as the darker the cactus plant, the less light it requires to survive.
How frequently should I water cacti?
The most frequent reason for cacti failure is improper watering, whether it is done too much or too little. Cacti have evolved to store water for extended periods of time and can maintain moisture through droughts because they are endemic to arid regions and dry temperatures. They have a limited capacity, which is why over-watering can result in a variety of issues.
When it comes to regularity, watering your cacti will largely depend on the season but also on the variety. Checking the soil is the easiest technique to determine whether your cactus needs water: It’s time for a drink if the top inch is dry. That entails applying the “soak and dry procedure” on cactus.
What is the soak and dry method?
The soak and dry technique is thoroughly wetting the soil until part of it begins to flow out the drainage hole, then waiting until the mixture is nearly dry before wetting it once more. If done properly, this strategy will help them endure a period of under-watering should you need to travel or leave the house because it takes use of their natural tendency to store water (or if you just get busy and watering falls to the wayside, as happens to all of us now and again).
Watering during the growing season versus the inactive season
Like with many houseplants, the season affects how frequently you need water. It becomes more crucial that you get in the habit of examining the soil to determine whether your cacti are thirsty. A healthy cactus needs watering every one to two weeks during the growing season, according to general wisdom. The frequency changes to once every three to four weeks during the off-season.
Even then, it’s crucial to examine the soil. The same way that not all interior spaces and not all cacti are alike. The only way to be certain that your cactus require watering is to carefully examine the soil to determine how dry it is because there are so many different factors.
Can cacti survive inside?
Despite being recognised for their love of sunlight, many cacti grow well as houseplants. For some unusual decor, place one on your windowsill or in your living area. The ideal houseplant, indoor cacti typically require less light and are smaller in stature.
Bunny Ears Cactus (Opuntia microdasys)
The bunny ears cactus gets its name from its look and is native to Mexico. Its two pads are designed like bunny ears. They should be handled carefully since they have glochids or brown prickles on them. The bunny ears cactus is the ideal indoor plant because it may reach heights of two to three feet. If given enough light, it will blossom with white flowers and bear purple fruits in the summer.
Chin Cactus (Gymnocalycium)
Gymnocalycium is a kind of cactus native to South America and is frequently referred to as the “chin cactus.” Greek for “naked kalyx,” its name alludes to the flower buds’ lack of hair or spines. Some chin cactus like shade, while others do better in sunlight, depending on the kind.
Saguaro Cactus (Carnegiea gigantea)
Although it grows slowly, the Saguaro cactus can reach a height of forty feet. This indicates that you can use it as an indoor plant for a number of years before relocating it outside. It has the traditional cactus appearance thanks to its barrel-shaped body. This plant, which is a native of the Sonoran Desert, needs a lot of sunshine. Place the plant in direct sunlight if it is being maintained indoors.
Old Lady Cactus (Mammillaria hahniana)
The mammillaria family, which comprises 250 species, includes the old lady cactus as a subspecies of pincushion cactus. It is renowned for its halo of small pink or purple flowers that bloom in the spring and possesses hairs and spines. A sandy potting mix should be used to plant the old lady cactus, and it should receive water every other week.
Star Cactus (Astrophytum asteria)
The star cactus, also known as sea urchin or sand dollar cactus, can be recognised by its circular body that is divided into eight slices. It has small white spots and white hairs all over it. It produces a yellow blossom in the spring. The star cactus is the perfect indoor plant because its diameter only reaches two to six inches.
Easter Cactus (Hatiora gaertneri)
Easter cactus, a native of Brazil, blooms in late winter or early spring. White, orange, and lavender are just a few of its bloom colours. The plant has a distinctive shape because of the way its spines are piled on top of one another.
Christmas Cactus (Schlumbergera bridgesii)
The Christmas cactus, which is frequently mistaken for the Thanksgiving cactus, blooms in the dead of winter. It boasts vivid red blossoms and is frequently given as a Christmas gift. The Christmas cactus thrives in average indoor settings. Don’t overwater plants because it will make their roots rot. Although this plant can thrive in low light conditions, its blossoms benefit from additional light.
Moon Cactus (Gymnocalycium mihanovichii)
The moon cactus, also referred to as the chin cactus, varies in size, shape, and colour. The hibotan cactus is a well-known cultivar. Its South American origins can be traced to its vivid red, pink, yellow, and orange hues. On window sills that receive some light, these little plants flourish.
