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 shriveling 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 liter 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!
Can cacti receive too much sunlight?
Sun exposure is crucial for your summer months (read the material on sunshine above for more details!) You need to be aware of the humidity, temperature, and daily amount of sunlight your plant receives. Succulents and cacti, despite being relatively hardy plants, can soon become sun-burned and dried out if the sun’s rays are too strong.
Take care while shifting a plant from the shade to full sun or from indoors to the sun once springtime rolls around. Even when you think you’ve done everything correctly, some plants occasionally succumb to the “shock” of such a rapid transformation and perish. The best approach is to gradually expose your plants to different environments and light.
How long does cactus require to be exposed to direct sunlight?
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.
Can cacti receive direct sunlight?
Cacti plants are well renowned for their ability to withstand droughts and their superior water-holding capacity. This is the main justification for calling them desert plants. Gardeners typically presume that these plants require direct exposure to bright and high heat to survive because the majority of them thrive in dry and semi-arid environments. Is that indeed the case? We’ll soon get the answer.
Do cacti need direct sunshine to survive? The majority of cacti species can survive without being exposed to direct sunshine. Cacti plants will thrive when placed in locations with good light, not necessarily direct sunshine, just like other succulents. Place your plants on a south-facing window if you’re growing them indoors so they can get plenty of strong light. In order to shield these plants from harsh sunlight if you are growing them outdoors, pick a suitable spot for them in your garden that has some shade.
Some cacti species can’t stand full, direct sunshine depending on where they were born. If you don’t provide some kind of shelter from the stifling heat, such animals are prone to damage and sunburn. However, a few other species have evolved a variety of adaptations that make it considerably easier for them to withstand direct and intense sunshine.
Learn everything you need to know about exposing cacti plants to direct sunlight in the following paragraphs, along with tips on how to shield your priceless tiny plants from potential harm.
How frequently do cacti need watering?
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.
Will my cactus survive outside?
Many gardeners think it’s nearly impossible to cultivate cacti outside or that these succulents can only survive in hot, dry climates. Thankfully, that is not the situation. Plants like cacti and other succulents are excellent for landscaping. They can grow and thrive in a variety of climates, need minimal upkeep, and are always simple to grow and take care of.
So, are cacti a healthy outdoor plant? Yes. Although cacti plants often flourish in indoor settings, many kinds can also thrive when planted outdoors. You can always locate a suitable cactus species that can survive outside, regardless of the climate in the area where you live.
While some cacti species can withstand extreme heat and light, other types thrive in cold winter settings. It is up to you to identify the species that will thrive in your region.
Can cacti survive inside?
Despite being recognized 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 recognized 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 colors. 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 color. 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.
The ideal lighting for cacti is.
Make sure cacti receive the most light possible whether they are kept inside or outside. If you keep your cacti outside, place them where they will receive the most light possible. Likewise indoors. Ensure they are positioned on a windowsill where they will receive sufficient light.
Your plant won’t live very long if you keep a cactus indoors and put it on a bookshelf, for instance. Although every cactus has a different preference for light, most cacti require strong, direct sunshine. Place your cactus outdoors or on a windowsill, balcony, or unsheltered greenhouse to give it enough light.
Cacti seeds don’t require a lot of light to grow. However, shortly after propagation, seedlings and young plants begin to require significantly more light. A newborn cactus will most likely die now if there is little light.
Artificial lighting for cacti
Use artificial light in place of natural sunlight if you can’t give your adult or young cacti plants access to it. Artificial lighting can be costly, so avoid buying bulbs that burn out quickly and produce little light.
The finest artificial lighting for cacti is provided by LED grow lights like these or fluorescent bulbs/tubes (or even tiny bulbs). Avoid using incandescent or mercury vapor lamps. For instance, 75w grow lights may illuminate a growing space of about 5–10 square feet. The number is frequently higher with fluorescent tubes.
Placing your cactus on a windowsill for light
There are several suggestions that can prevent burns for plants that are kept on windowsills. When it’s really hot outside, sunlight passing through windows will raise the temperature behind the glass by about 50 degrees Fahrenheit while keeping the interior temperature substantially lower.
Your plants may be severely burned by these intense solar rays. So, if it’s over 100 degrees outside, make sure to place your cactus on a windowsill where it is protected from the sun. Cacti with fewer or smaller numbers of spines require greater protection.
This is especially true if your cactus is located on a windowsill facing south, where the sun shines the most. You can shift your cactus to an east or west facing windowsill during really hot weather. If you have a balcony, you can put your cactus there as well. Try to move your cactus outside during the summer months if you can, as windows obstruct the majority of incoming light.
Cacti kept indoors in winter
You’re undoubtedly wondering, “How can I give my indoor cacti light in the winter? So, in the winter, you should put them on the window sill with the most light—often the one that faces south—and give each cactus enough room to get as much light as possible.
Additionally, make sure the windows are clean. Wintertime window dirt accumulation can obstruct up to 25% of entering light.
Protecting your cacti from burns after the end of winter
The majority of cacti grow in environments where they are exposed to natural sunshine all year long. Your cactus may experience burns after the winter if you live somewhere with cold winters and few hours of sunlight. Your cactus haven’t spent a lot of time in the sun over the winter, so when they are suddenly exposed to strong solar rays, they may burn.
For instance, sunshine hours begin to rise in various states of the United States in March or April. Additionally, if you don’t protect your cactus from such intense sunlight, they will burn. The epidermal tissues on the stem may experience necrosis (death), which would impede breathing and metabolic functions. So a burned cactus may even perish or at the very least lose the majority of its spines.
So, how can you keep your cactus from getting burned after the winter? Your goal is to minimize the quantity of light reaching your cacti rather than completely block it. You can accomplish this by affixing some kind of plastic sheet, paper, or even gauze to the glass side.
Do all cacti need bright and direct light?
No, not all cacti require direct, bright light. Because they can be killed by direct sunlight, certain cacti also prefer bright but indirect light. There are some cacti, though, that detest strong light and are severely harmed by it.
For instance, the epiphytic cactus genus Rhipsalis prefers shade and primarily inhabits tropical rainforests despite detesting intense, direct light. There are about 35 different species of Rhipsalis, with the mistletoe cactus, or Rhipsalisbaccifera, being one of the more well-known varieties.
Some cacti, such as those in the Mammillaria genus (including the globe and nipple cactus), barrel-shaped cacti, tiny cacti of the Gymnocalycium genus, or chin cacti, like intense light but may tolerate partial sun.
Let’s not forget that even cacti that like strong, direct light occasionally require a period of low light. After repotting or after administering parasite treatments, protect these light-loving cacti from harsh, direct light. The transitional time following winter is similar.
Cacti and ventilation
As well as dry air, your cactus require sufficient airflow. Make sure to leave a window open if you are keeping your cactus on a ledge so that it may get fresh air. Additionally, for good airflow if your cacti are in a greenhouse, be sure to open a vent (or have an automatic vent).
A greenhouse needs to be properly ventilated, especially in the spring and summer. High humidity and stagnant air are toxic to cacti. In order to give your cactus more fresh air throughout the summer, it is typically a good idea to bring them outside.
Cacti temperature needssummer and winter
High summer temperatures typically cause cactus in their native habitat to go dormant. To endure the intense heat, they now slow down their growth.
And cacti begin to grow as soon as it starts to rain and get cooler. You don’t need to make any changes if your state or country experiences consistently warm winters and hot summers, along with frequent rainfall. Again, the type of cacti will determine everything.
However, if you reside somewhere with chilly winters (like the majority of US states or the UK), you must allow your cactus to grow in the summer and rest in the winter. This is due to the fact that your cactus cannot grow in the dark winter months.
Therefore, if you live somewhere with a chilly winter, you must lower the temps to between 45 and 55 degrees Fahrenheit in order to aid your cactus in going into dormancy (7-10 degrees Celsius).
You will also need to lessen how often you water (once in a week or so). Temperatures must be lowered. Since if you don’t, your cactus will dry out because they will have to evaporate water to stay cool. Additionally, keeping your cactus warm indoors will keep them from falling dormant. even have winter blooms on some cactus.
