How Often Should You Water Cactus Indoors

  • 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.

What signs do a cactus show when it needs water?

Fair enough, it can be challenging to make the appropriate decision. Everyone will give you different recommendations because there is so much conflicting information available. Additionally, many plants have various preferences. How do you even begin?

But the story doesn’t end there. You know, a number of things might impact how frequently you should water. To name a few:

  • Temperature
  • Humidity
  • composition of the soil
  • Light intensity
  • Season
  • Dormancy
  • Species
  • Outdoors versus Indoors

There are other others, but we won’t go into them now. The most crucial thing to keep in mind is that, even though 10 days is a solid guideline, you should constantly be aware of the shifting circumstances. You should adjust your watering schedule to account for them.

For instance, it’s well known that throughout the summer, you should water your plants more frequently. It is, after all, much hotter. Water evaporates more quickly, and your plants do too!

Arizona experiences intensely hot and arid summers. Your succulents will need water as frequently as possible if they are in a climate like that. You should water them every day or every other day in those conditions, believe it or not.

The East Coast, including Virginia, can have extremely hot summers. The humidity, nevertheless, is also quite high. Evaporation proceeds far more slowly here than it would in Arizona since the air is already so heavily laden with water. In this situation, we advise watering every five to six days.

Naturally, winters are the opposite. Days get shorter, the sun shines less, and the temperature drops. Some of your plants enter a dormant state (much like a bear hibernating).

You water significantly less regularly throughout the winter (especially for outdoor plants). Depending on how often I remember, I water my indoor plants once every two to three weeks. Sedum and Sempervivum are examples of outdoor, cold-tolerant plants that may never need watering since the odd snow or sleet is more than enough.

Root Rot

The risk of root rot is the primary reason we lay such a strong focus on watering regularly.

The quiet killer that kills the majority of succulents and cacti is root rot. Because it takes place underneath the soil’s surface, you won’t even notice anything is amiss until the plant topples over due to a rotting core.

Why does root rot occur? In a nutshell, roots will begin to decay if they are left in water for an extended period of time. This is due to the fact that plants actually breathe through their roots and that air does not travel well through water.

The succulent essentially drowns. It also doesn’t need to be a lot of water. Root rot can develop only from being damp or moist for an extended period of time.

Because of this, frequency of watering is more crucial than quantity. Giving the succulent adequate time to dry out in between waterings is essential.

How to Know if the Soil is Dry

The first step in keeping your plant dry is to have a fast-draining soil that is primarily formed of inorganic components. Step two involves watering only when the plant has completely dried.

It is simple to determine whether the soil is dry. The simplest method is to just insert your finger into the saucepan. A minimum depth of two inches is required since sometimes the surface may be dry but the ground beneath may not be. Don’t water if it feels damp, wet, or even a touch colder than the surface. Allow a few days.

To check, you can also use a soil moisture meter. These tools are extremely helpful for inspecting numerous plants, however the less expensive models can be somewhat incorrect.

Finally, just watch for your succulent or cacti’s leaves to wrinkle. Though it seems frightening, the plant is not actually damaged. Instead of erring on the side of wet, choose dry.

How much water should a cactus receive?

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.

How frequently should a tiny cactus be watered?

The majority of desert cactus can survive without water for up to two years. For indoor cactus, however, this isn’t true because of the drastically different environmental factors.

Cactus plants in small pots can last up to a month without water. It’s better not to leave them go for too long, though, as if left neglected for too long, they could dry out and perish.

Make sure to hydrate your small cacti well once or twice a week in order for them to thrive.

Despite being drought-tolerant plants, cactus still require watering to survive.

How long can cacti grow inside without water?

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 should a cactus be 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.

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!

How are indoor cacti cared for?

As long as they are placed in an area that receives at least 4 to 6 hours of sunshine every day, cacti can be cultivated indoors. To ensure they are etiolated, we advise rotating them daily in your brightest windowsill, which is typically a southeast-facing window.

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.

Do I need to water my cactus?

The watering needs of cacti and succulents varies slightly from those of other plants.

Succulents and cacti don’t need as much water to survive as other types of houseplants because they resemble desert plants.

That does not imply that you should skip watering dried-out succulents. But many individuals question if misting succulent and cactus plants occasionally is appropriate.

Succulents and cacti shouldn’t be misted when being watered because it can weaken the roots and promote fungus. Do not shower succulents and cacti with a spray bottle. Spray misting is not only insufficient in terms of water supply; it also runs the risk of making the plants rot.

While it is not advised to spray these plants, there are a few circumstances in which you should sprinkle cacti and succulents.
