- 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?
With their striking shapes of all kinds and stunning color variations, cacti are among the world’s most distinctive and lovely plants. They go well with a variety of home decor themes, including minimalist, boho, and, of course, anything with a southwestern influence! Who hasn’t had the need to collect each and every one of the miniature cactus plants on display and take them home? Plants require proper care once they have been adopted because they are more than just static decoration. Cactus plant care isn’t tough, but it is a little special, just like the plants themselves! Below are our top five suggestions.
Location Observation
You may probably imagine what type of environment cactus prefer since they typically grow in desert climates! Sunlight in plenty. But take care! Even cactus can burn, particularly if they are in full sunshine and positioned behind a glass window, which intensifies the effects of the sun. The best window is one that faces south. You may need to move your cactus to a cooler location if you see that the side facing the sun is beginning to turn yellow or brown.
Keep your cactus in a bright area of the house, such as one with artificial lighting. You can put your cactus outside on the patio throughout the summer to take advantage of the intense summer sun.
Hydration Fixation
For many plant owners, watering cacti plants has been a worrying thought. We are aware that they require water because they are plants, but we have also been warned about providing them with excessive amounts of water because they originate from the desert. Cacti actually require regular waterings; they only have a particular defense against drought.
The need of water cannot be overstated if you want your cactus to grow. You can feed them water once a week if they are in a sunny area with good daytime heat. The sole need is that the soil be completely dry between waterings. This will prevent the plant’s bottom margins and roots from rotting or becoming wet.
You can use less water in the winter because there is less sun and it gets colder at night during this season, which causes cactus to go dormant.
Flirt with the Dirt
A variety of cacti species are grown together in a container garden to create an oasis of lovely plants, and these gardens are highly popular. This frequently necessitates repotting the cacti! Consider the type of soil you’re using in the new container in addition to constantly wearing thick gloves (or using salad tongs to pick up and handle the cactus). Cacti prefer their own distinctive flavor of dirt, thus it must be highly efficient at draining surplus water. Many nurseries and flower stores sell bags of cactus soil, which is sandier and rockier than standard potting soil. This is necessary to ensure that the water drains and doesn’t keep the cactus damp.
Plotted and Potted
Take a close look at the container you are selecting before you repot the cactus. The best option is undoubtedly a container with drainage holes, as you won’t have to worry about the bottom collecting water. Cacti can, however, also be grown in containers without drainage holes; it just requires a little more attention. Always check the soil before watering to make sure it is completely dry. To avoid unintentionally drowning your cacti, another alternative is to meter the water you use. Depending on the season, a 1/4 to 1/2 cup per week or two is sufficient to ensure the health of your cactus.
In the Mood for Food
Fertilizer can be quite beneficial for cacti, and there are specific types with the nutrients they require. (An additional excellent alternative for a well-balanced supper is a 10-10-10 fertilizer.) Since they love to be fed in little quantities frequently, you can fertilize them sparingly with each watering during the summer growing season. In the winter, decrease your efforts to give the plants time to recuperate.
BONUS TIPDress up Your Cacti
Cacti are lovely guys on their own, but it’s always fun to give them a little makeover! From a lovely pot with extra personality to organic accents. Traditional containers for these desert-dwelling plants are made of terra cotta or clay, although a glass terrarium-style planter or ceramic dish can also be used. We enjoy placing stones and pebbles of various sizes and colors on top of the ground. We also include wood, sand, and big rocks. Make sure you can still use a finger or a moisture meter to determine if the soil is dry or not.
Browse through our collection of cactus! We enjoy potting up lovely planters filled with varied succulent and cactus species and celebrating the uniqueness of each individual plant.
Don’t be reluctant to adopt some of these beautiful plants now that you are an authority on cactus maintenance! Have fun picking out your favorites and bringing new companions home to make your own lovely and joyful cactus gardens.
When exactly do I need to water my small cactus?
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 frequently should I water my cactus?
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.
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.
Do cacti require sunshine to grow?
Direct sunshine is necessary for cactus plants to develop and thrive. They do, however, require the proper quantity of heat and light.
The ideal amount of sunshine for cacti is between four and six hours per day. Don’t expose them to the sun for too long, though. Their skin may burn and crack as a result of this.
The cacti’s growth will be slowed if they do not receive enough light, and if there is too much sunshine, it could burn and cause harm.
Just keep in mind not to expose them to the sun over extended periods of time, to direct sunlight all day, every day, and to always provide shade for your cactus.
Your cactus should thrive as long as you give it both sunlight and shade!
Cacti are watered either from the top or the bottom.
Cactuses need regular summertime hydration to grow and stay healthy, but if you overwater it or mist it too frequently, it could rot from the base up.
Follow the advice of knowledgeable cactus growers and water from the bottom. Put the potted cactus in a shallow saucer that is half-filled with water every week during hot weather, or whenever the pot feels light, and leave it there for approximately a half-hour or until it soaks up the water. Enough water will be absorbed by the soil for the plant. Furthermore, since the majority of the moisture will be near the pot’s bottom, deep rooting will be promoted.
