It does not, however, totally survive without water. Every living thing needs water, yet cacti are specifically built to thrive in dry environments and make better use of the water they do receive than other plants. It doesn’t lose its water through evaporation as quickly as other plants do since it lacks leaves. Its stems are robust, offering plenty of space for storing water and a lid that keeps the water within. Some cactus species may survive without water for two years. Depending on the species, the indoor types do need to be watered more frequently.
How long does a small cactus need water?
What images do you have in mind when you consider cacti? You probably picture a desert plant that can go without water for extended periods of time and yet thrive. Although these plants have adapted to living in deserts and like dry soil, they nevertheless need a significant amount of water, especially during the growing season.
A cactus can survive without water for how long? Normal desert cacti can go without water for up to two years. This is due to the fact that it has grown thick stems that can store a lot of water and have a barrier that stops water evaporation. The conditions are very different for indoor cacti, thus this does not apply to them. Depending on the species, indoor variants do require frequent watering.
How frequently does a little cactus require water?
Unfortunately, you cannot establish a constant watering schedule for this desert plant because, as was already indicated, a variety of conditions alter the plants’ watering requirements. For instance, because of the varied growing conditions inside and outdoor cactus, respectively, require less watering.
The age of the plant is another aspect. Cacti that are younger tend to be more demanding and require watering more frequently to promote their growth. Due to their aggressive growth, these plants also need more watering in the spring and summer than they do in the cooler months.
Small indoor cactus plants often require watering every 10 days or more to flourish at their best in the spring and summer, as soon as the soil has completely dried out. When a plant is dormant throughout the winter, extend the time between waterings (approximately every 4 to 6 weeks).
What occurs if a cactus isn’t watered?
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.
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.
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!
Are small cactus water-required?
Like other succulents, mini-cacti require well-drained soil and require less water than other plant types. You may decide on a watering regimen for your mini-cactus with some careful observation. Generally speaking, water should be added when the top half inch of soil feels dry. When watering, fully wet the soil, enabling it to absorb the liquid; if it does so too soon, add extra liquid until it escapes the drainage holes. Most cacti require weekly watering.
How many years do little cacti live?
Carefully! To loop around the top, use either very thick gloves or folded newspaper. With tweezers, you may remove huge spikes that have stuck you. Small spikes can be removed by covering them with duct tape, ripping it off, or quickly massaging the area with a ball of old tights. The experts at Thejoyofplants.co.uk suggest using olive oil to refine the final fine spikes.
What pests do you need to look out for?
Verify that the plant’s body (the cactus’ “body”) and the root system are devoid of mealybugs. It is one of the most prevalent and challenging cactus pests, with a fuzzy white wax coating that contains oval insects. Additionally, aphids, scale insects, thrips, and red spider mites (eight-legged pests that cover a plant in a delicate, dense web) can appear. Check for damage and make sure the root system is sound. Cacti that have been kept in excessive moisture for an extended period of time may have rotted “from the pot,” which can also be brought on by fungi and bacteria. The real stem, which is green, may then feel supple.
Are all cacti prickly?
No. Cacti are typically thought of as desert plants, however there are also forest cacti that lack bristles; nonetheless, the variety that can be grown indoors is extremely limited.
How long does a cactus plant live?
Cacti can live for hundreds of years in the wild. They could live for ten years or longer indoors. The issue with old ones is that every single bump, scratch, or imperfection they receive stays with them; as a result, as they age, they start to look less attractive.
Succulents can survive three weeks without water.
In general, succulents that are grown indoors or outdoors during the cooler months will need less water. They can go without water for one to three months.
Indoor succulents will be less exposed to the weather outside because the soil dries out more quickly outside than it does indoors due to the wind and sunlight.
The soil remains moist for extended periods of time in milder climes, typically fall and winter.

To avoid root rot, it’s crucial to examine the soil before watering indoor succulent plants and to make sure it is completely dry between waterings.
How can you spot a dying cactus?
When a cactus looks shriveled and husk-like, it is dead. Additionally, dead cacti can become unstable in their soil and topple over. They could start to smell rancid and becoming mushy, both of which are indicators that they are rotting. Cacti that are dead lose their spines and frequently appear brown.
Fix root rot in Cactus
Cactus root rot can be identified by symptoms like discoloration, shakiness, and mushy roots. Your cactus becoming brown or black is another sign.
Here’s why cacti plants frequently develop root rots:
In order to enhance water collection in their native habitat, cacti have a large, shallow root system. Root rot can develop very quickly in a pot due to overwatering, compacted roots, or poor drainage.
Water that does not drain properly and is standing around the plant’s base can occasionally only impact the cactus’ base and not its roots. These are some of the most frequent issues with growing cactus inside.
If you act promptly after noticing that your cactus plant is becoming mushy, you might be able to fix the issue. With the right care, even cacti that have decayed all the way to the soil level can recover.
As soon as you’re certain that your plant has root rot, immediately perform the following steps.
Take your plant out of the pot and examine the roots to see how they are doing. Use a sterilized knife to remove the discolored, mushy roots and any rotten parts at the cactus’ base if any are still white.
Prior to repottiing the plant in a fresh container with new cactus potting mix, let it dry out and heal outside of the soil. Always use protective hand gloves or a piece of folded newspaper to shield your hands from the cactus’ sharp spines.
Watch Your Watering
One of the most effective techniques to rescue a dying cactus is through optimal irrigation. Similar to how lacking water is harmful, having too much water is also harmful. However, it’s best to err on the side of caution when dealing with cacti. You should water your succulents as regularly as indicated above.
Additionally, it’s critical to water the cactus plant thoroughly while keeping an eye out for the following:
Under-watering your cactus
If you don’t water your cactus often, it can pucker or shrivel as well as becoming discolored (usually getting brown and dry, or calloused). These symptoms are your succulents and cacti’s method of communicating to you that they are thirsty and dehydrated. Give them a nice thorough watering to fix the problem.
Over-watering your cactus
Encourage the cactus to shed as much water as rapidly as possible if overwatering is a persistent issue.
Choose an unglazed clay container that is only marginally larger than the cactus and fill it with a ready-made cactus mixture to accomplish this. To avoid upsetting the cactus’ delicate roots, pot it gently in the mixture. In contrast to the loose cactus mixture, which allows water to drain rapidly and completely, the clay pot will wick away more moisture from the root zone.
Landscape plants provide you less control over drainage, therefore you should only plant very large landscape cacti directly in the ground.
Change the potting soil
As we’ve already seen, the main factor contributing to cacti root rot is overwatering. Let me be very clear about one thing, though.
The rots aren’t directly brought on by water; instead, Phytophthora spp., a type of water mold, is to blame. But the rot won’t start unless there is enough moisture, which you happily provide it when you overwater.
The pathogen that first caused the rot is likely still present in the current soil, which is the first explanation. The second and most significant issue is that some potting mixtures are considered to be heavy and likely hold too much water.
Due to this, you must switch to a lighter, more permeable potting soil, such as this Classic Potting Mix. What I appreciate about this mixture is that it has a high level of disease resistance, offers excellent drainage, and absorbs just the right quantity of water.
Read this post about how to increase drainage in potted plants to learn more about how to do it.
Repot your cactus
Giving the cactus plant a greater growing space is a frequent justification for repotting.
When houseplants ultimately outgrow their pots, the roots cluster together and get compacted. Without enough room for the roots, a plant will frequently grow slowly and may even perish.
Water that seeps right through the container, roots that are obviously congested, leaves that appear unhealthy, and roots that are growing through drainage holes or above the soil line are indications that the plant has outgrown the container.
The roots can spread when the plant grows larger when the plant is moved to a larger container.
To get rid of any unwanted guests, make sure to properly disinfect the new pot using a solution of one part water and one part bleach.
Choose your pot wisely
Although I highly advise potting up, you should be careful not to pick a pot that will actually cause issues.
The roots may eventually rot if the pot is too large and contains too much dirt, which will allow it to retain too much water.
You need to stimulate some new root growths when roots or tissues have been severely harmed by overwatering or other undesirable cultural practices.
A full cactus plant can regrow from even a small amount of healthy tissue, but if you leave the rot in place, it could spread further.
Till a thick scab appears on the portions that were sliced, let the cactus dry on the counter for a few days. If there is still much of the cactus, bury it about halfway; otherwise, place the remaining piece of the plant in a clay container with cactus soil.
Water the cactus lightly during the first week and then only when new growth starts to show.
Let your cacti rest
Sometimes, your cactus may not require rescue, and you may simply be being overly cautious. It’s possible that when certain portions die off or lose their buds, they are merely requesting a rest.
Don’t worry if the cacti lose their buds one winter; they should bloom the following year.
There shouldn’t be any cause for concern as long as the crucial areas, including the roots, appear healthy.
Provide optimum temperature
If your cactus isn’t flowering, it can be because of the temperature or the amount of daylight it receives.
For six weeks, days must be between 8 and 10 hours long and nights at least 14 hours long to start blossoming. You might need to cover your cactus if your home has bright indoor lights at night.
Only at cool temperatures of 50 to 55 degrees F will flowers bloom.
Watch out for mealybugs
Mealybugs exude wax and sticky honeydew, which lowers plant quality and weakens the phloem of your cactus plant by sucking sap from it.
a large population Although leaf drop and plant growth can be slowed by feeding on the foliage or stems, healthy plants can withstand low populations without suffering serious harm.
Since indoor plants are typically not exposed to the natural enemies that frequently keep mealybugs under control outdoors, cacti are particularly vulnerable since year-round mild temperatures foster mealybug populations.
To ensure that you find and control them in good time, regular monitoring and inspection of your plants is essential. By reading this article on how to control pests, you can discover more about handling mealybugs (mealybugs).
Feed them well
The majority of plant issues, including a dying cactus, can be due to inadequate nourishment.
As a result, it’s crucial to feed your cactus at the most appropriate rate and frequency with a fertilizer that has been prescribed.
Feed a complete cactus fertilizer every two weeks from early spring to early fall. Feed the cactus once a month in the fall and winter.
A plant that has received too much fertilizer may wilt despite being watered, have leaves that feel like they are made of fabric, or have brown leaf tips.
Follow the directions on a fertilizer packet carefully, and if in doubt, use a smaller amount than advised. Ensure that the fertilizer you use is labeled as being suitable for indoor plants.
Light is more important for the cactus than you think
When a plant needs more light, it can eventually grow lanky, floppy, pale, or start to drop its leaves. It is probably not getting enough light if it is expanding yet the new growth is pallid and fragile.
Protect your cactus from prolonged exposure to direct sunlight
An otherwise healthy plant will develop this stiff, dark, bark-like tissue just above the earth. Actually, it’s a result of cacti’s natural aging process. Always work your way up from the cactus’ base when corking.
A cactus is an indication of sunburn or another issue if it turns brown from the top down, though.
A whitish discoloration, typically at the top and side facing the sun, is a symptom of mild sunburn. On the charred surface, severe burns leave behind hard, dark scars.
Brown scars on cacti indicate permanent harm. Moving your cactus into the shade will help it recover if the only discoloration it has is a whitish one.
In order to acclimatize cacti that aren’t used to being in the sun, full sun must be provided for a brief period of time each day, followed by an increase in exposure over the course of several weeks. Some creatures should never spend the entire day in the sun.
