Every cactus is unique, so it’s up to you to figure out how to care for it by paying attention to how it changes whether you water, repot, fertilize, or propagate. Knowing how frequently to water your cactus is crucial for the plant’s survival.
These plants have the wonderful quality of being very tolerant to water neglect. Their leaves or stems will turn pale or yellow if they are neglected too much, though.
Here are some pointers to help you choose how frequently to water your cactus:
Cacti require routine fertilization and watering from March to September, when they are in full growth. To keep them from drying out, water them at least once every week. Only water them when they are fully dry when dormant.
Make sure the topsoil is totally dry before the subsequent watering cycle. To assist you determine the moisture level, you might purchase a water gauge. An alternative is to insert a stick into the ground; if the stick comes up dry, the plant needs water.
Be out for warning signs of overwatered or underwatered cacti. When a cactus is underwatered, it will appear pale, and when it is overwatered, it will appear unusually fat, which finally causes root rot.
When should I begin providing water to my cacti?
The British Cactus & Succulents Society committee member Ian Thwaites says: “Very few of the common cacti and succulents succumb to neglect, but too much kindness can frequently lead to their mortality. Contrary to popular opinion, these plants are typically found in regions with lower rainfall rather than genuine deserts. They have the capacity to hold water, unlike other plants that would dry out and shrivel during droughts. If you can meet the following five criteria, Ian claims that cultivating cactus is easy:
- Cacti require compost that is well-drained. To two parts multipurpose compost, add one component grit.
- Choose a sunny windowsill, conservatory, or greenhouse for your cacti because they need lots of light.
- Between the middle of March and the end of September, observe the growing season. Give cactus a good watering during this time, then wait until they are completely dry before you water them again. Avoid allowing them to remain in a wet saucer for too long. They should occasionally be fed with a liquid tomato fertilizer because a “soggy bottom” could be fatal.
- Follow a cool winter rest (5C is excellent) without watering the rest of the year.
- Pests like mealy bugs or red spider mite should be watched out for and treated with the proper insecticide.
These plants are excellent for novices and come from the South American Andes. Since they are self-flowering, you may observe the buds forming right after Christmas. You’ll be rewarded with a springtime flower display if you resist the need to water them until mid-March. When they outgrow their pot, these plants will benefit from repotting because they grow easily on a windowsill.
The majority of the plants in this, the biggest cactus genus, are native to Mexico and the United States. The majority of types are excellent for growing on windowsills and will provide you with a ring of tiny blooms all summer long. The traditional Mother’s Day plant in Holland is Mammillaria zeilmanniana, which Dutch nurseries cultivate in their millions just for the occasion.
This is a group of plants distinguished by the size of their evening-opening, usually-morning-finishing flowers. The blossoms have a strong aroma, and you may expect to see blooms all summer long. In recent years, a lot of work has gone into creating magnificent hybrids whose blossoms may be quite showy and now last for a few days.
The upkeep of this trendy succulent plant is the same as that of a cactus. The design and shape of the rosette of leaves, which range in color from variegated “Compton Carousel” leaves to silvery-blue leaves that should not be touched since they are covered in a powdery bloom, are what give the plant its aesthetic appeal.
a vast genus of succulent plants, the species of which differ greatly. While other species like a little more warmth, Euphorbia obesa, a perennial favorite of collectors, is the most common. These South African plants feature what appears to be a plaid pattern on their skin. Since male and female blooms are produced on different plants, you will need two of these intriguing plants in order to create seed.
These real miniatures, often known as living stones, won’t ever expand your house or collection. They are simple to take care of as long as you adhere to their expert recommendations: once they have completed flowering (in September or October), you should stop watering them. This will stimulate the plant to produce new leaves beneath the old ones. The old leaves will gradually wither away, exposing the fresh bodies beneath. The new leaves will sprout after the old ones have completely dried up (in May), and in the fall, they will bloom in either white or yellow. Water them like you would cactus.

After purchasing a cactus, should I water it?
If a cactus has caught your eye when shopping for a low-maintenance houseplant, you are in for a real treat. Cactus plants make wonderful indoor plants and are typically simple to maintain. Knowing how frequently to water cactus plants can be difficult because it is so simple to be overly enthusiastic with the watering can.
When should a cactus be watered? Once the earth has entirely dried up, the majority of cacti should be watered. When watering a cactus, pay attention to the health of the plant and how dry the potting soil is rather than following a timetable. How frequently to water cactus plants depends on a number of variables, including size of the cactus, pot size, season, temperature, and humidity.
It’s critical to comprehend your cactus’ water needs. Cacti are succulent plants that are made to retain water in their stems and roots so they can withstand dry spells. There are several methods you may employ to make sure you always know when to water your cactus, even if each cactus has a varied water demand.
How frequently should I water my brand-new cactus?
Watering. The most frequent query we receive at the nursery is this one. Let me start by stating that each circumstance is unique. If you are successful, don’t pay attention to me.
The guidelines that have always worked for me are:
Cacti in the ground appear to be kept from stressing out as much and grow more uniformly when there is slow, deep watering. This practice is also known as “deep soaking.” A deep soak is a two to six-hour drip from a garden hose that is slow yet constant. The length depends on the size of the plant.
I water my plants twice a day. I first water multiple pots at once (about a 4 foot length) until the pots are full. I return and water the plant once more to ensure that the soil in the pot is well moistened.
Daily temperatures play a role. More watering is needed when the weather is warmer. It takes less irrigation to maintain plants in cooler climates. For more details, see “Seasonal Watering Tips” below.
Size of the plant matters. You will need to water a plant less frequently as it grows larger and becomes more established. It can go longer between waterings since it has a bigger “storage tank.” For instance, a big Saguaro would never require watering, yet a tiny 1 gallon gold barrel might require watering as much as once per week.
Don’t give newly planted cactus any water. The same guidelines still apply whether repotting or adding to your landscape: plant dry and wait to water. Weather has a big impact on watering; the colder it is, the longer you have to wait to drink. Usually, you should leave succulent roots at least a week to recover before exposing them to water. Only re-water when the soil is completely dry at the roots; every circumstance is unique.
Seasonal Watering:
Summer is defined as three days in a row of 90 degrees or higher during the day. A deep soak is a two to six-hour drip from a garden hose that is slow yet constant. The length depends on the size of the plant.
Wait one week before watering for the first time if the daytime temperature is OVER 90. Wait two weeks before watering for the first time if the daytime temperature is UNDER 90. Exceptions:
When it is over 90 degrees outside, agaves need to be watered right away. Wait longer to water if the temperature is lower than 90.
You should never water saguaros. There are also some reasonable exceptions to this rule. If the area is really dry and your saguaro is clearly getting smaller, we may be experiencing a drought and you may need to water. This is not a free pass to wash the plant down everytime the thought enters your head; do it with a purpose. Since it seems to be so unusual, I have never understood what is meant by the term “Common Sense.” And no, your next-door neighbor is not the greatest person to ask about the plants you use in your landscaping. The man from New Jersey who lives next door might not be a better source of guidance if the nurserymen suggested following a precise design! A man in a loud voice who is far from home is an expert.
Initial Summer (except Saguaros) When the temperature is OVER 90, both native and non-native cactus should have a deep soak every two weeks. Agaves may need watering once per week in extremely hot weather, although this is typically too frequently. Because their roots are constantly exposed to extremely hot temperatures, plants in pots in full sun are a peculiar situation that require frequent hydration checks. After waiting 15 or 20 minutes, insert an unfinished wooden dowel or wooden paint stirrer all the way to the bottom of the pot to check for moisture. The important thing is to use unpolished wood so it can absorb moisture. You will quickly discover the routine you need to adhere to in order to maintain your plants.
Native and non-native cactus should receive a deep bath once a month if the daytime high is UNDER 90 degrees, but ONLY if there hasn’t been more than an inch of rain in the previous 30 days. Do not water if there is more than 1 inch of rain in a 30-day period.
Native cactus should receive a monthly deep bath if the daily high is OVER 90. Cacti that are not native to the area need two deep soaks per month.
Even in the absence of winter rainfall, it is advisable to avoid watering native cactus. Cacti that are not native to the area should receive a monthly deep bath.
After the third summer, native cacti should have naturalized and no longer require watering (apart from Saguaros). It’s best to naturalize non-native cacti so they don’t require watering. However, a long soak is advised once a month when the weather is really hot and there hasn’t been any rain.
Must I mist the cactus?
Regarding how to water these plants, there are various schools of thought, but one thing is undeniable. Don’t mist cacti in the desert. They are not indigenous to areas with high levels of humidity and surface wetness. Instead, they dig down into the earth to extract any lingering moisture from the rainy season. Cacti in the jungle are a little different and benefit from misting. The Christmas cactus is an illustration of this kind of cactus.
Generally speaking, as most planted cacti are desert dwellers, overhead watering should be avoided. Potted plants can be placed in a saucer of water to allow the roots to absorb moisture. After the earth has become wet halfway up, remove the plant from the saucer.
Another way to water cactus plants is to merely sprinkle water on the soil’s surface. Heat, direct light, and the location of the planting are some of the elements influencing the amount of water in this scenario. Typically, once a week is plenty for a slow, deep watering. This could mean soaking a container until water flows out the drainage holes or using a garden hose at a low setting to drip water steadily for many hours into the plant’s root zone.
Just keep in mind to water your cactus plants wisely and to identify the variety and origin of your plants. This can make choosing when to water plants much simpler.
What kind of cactus should I water?
- Watering cacti should only be done when the potting soil is at least 90% dry.
- Small to medium-sized indoor cacti, which are succulent plants, often require watering every 10 days or more during the spring or summer and every 4 to 6 weeks during the winter.
- The ideal way to water cacti is to completely saturate the soil with rainwater or distilled water, and then to stop when water begins to drain from the drainage hole in the potting container.
How exactly do you water a cactus?
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!
