How fast do cactus grow is a question that you would ask if you have a home garden of some varieties of cacti and running out of patience with the progress, you must be wondering how tall it will get.

How Fast Do Cactus Grow

The truth is that cacti grow extremely slowly, with most varieties only growing a little annually. So practicing patience while keeping cacti is significant.

This article answers this in more detail and lists some fast-growing types for your garden. 

How Fast Do Cactus Grow?

Cactus grow from 0.7 to 1.1 inches on average by the year. The reason for the slow growth is because of where you have placed it, because it needs an environment that is similar to where it comes from, which is the desert.

What Is the Reason of Cactus Slow Growth?

Cactus slow growth reason is that it doesn’t have enough because of the environment being high in moisture and less in heat, it doesn’t mimic the desert. In addition, it doesn’t have branches or leaves to perform photosynthesis, hence it grows slow, as light will not be transformed to energy.

These are some of the questions you’re asking yourself if you’re unfamiliar with cacti. And you might be a little concerned that you’re doing something incorrectly. There is no need to worry, though. 

Although cactuses do develop, their growth is sluggish and laborious, and it may take them a few years to reach their full size. All of these subjects will be covered in this blog, along with advice on what could slow your cactus’ growth even more and what you can do to hasten it.

What Is the Reason of Cactus Slow Growth

Cactuses don’t generally grow quickly, yet not all have the same growth pace. Some cacti develop at an agonizingly slow pace, while others might do better. Cactuses typically grow a few inches annually or a few inches every two to three years in some situations, however, some would even thrive much more.

The Carnegiea gigantea, for instance, has a growth rate of up to  six inches per year, but this is a rather uncommon exception. Most cactus species have modest growth rates in the single-digit range.

It is crucial to remember that cacti can thrive in environments with intense heat and little to no moisture. A plant that has evolved to withstand extreme weather won’t be disturbed by the need to grow quickly.

The lack of branches and leaves, rich in chlorophyll, the substance responsible for converting sunlight into energy, limits cacti’s ability to develop and makes it grow slowly.

These plants will grow slowly and laboriously to adapt to the harsh desert climate where they are native since they lack the leaves and branches that would help cacti produce energy.

How To Stimulate Cactus Growth?

To stimulate cactus growth you must provide it with light, place it in the proper potting mix, and adopt a watering technique. On another note, you must also preserve the optimal temperature for your plant, and provide the right fertilizing needs.

Despite its inclination to move slowly, there are a few things you may do to speed up your cactus’ growth to make the cactus grow faster.

The species of cactus you’re using and the environment you’re providing will determine how much you can speed things up. Although you should anticipate a small growth surge, the following advice will help your cactus grow and stay healthy.

– Provide Light

The absence of enough lighting in your home may be one of the causes of your cacti’s slower-than-expected growth, so what you should do is give it some proper lighting. 

Find them a sunny area near an east or south-facing window because they require around four hours of direct sunshine daily. To guarantee that the entire plant receives light, rotate your cacti occasionally. 

On another note, cacti also require equally distributed light. One side’s green tint will turn yellowish-white if it gets too much light. So make sure the light is spread equally.

– Potting Mix

Cacti typically thrive in small pots, especially while they’re young and developing. However, overcrowding them in tiny containers will impede their development. Repotting will be necessary as the cactus develops and grows since it will require more nutrients.

Of course, you don’t want to choose a pot size that is excessively large. If the pot is too large, you risk overwatering the cactus and having too much water in the soil, which can eventually cause rotting problems.

To prevent overstressing the plant with frequent transplanting to different containers, only replant when the cactus outgrows its present pot and only in the next size up.

Potting Mix

Plastic pots don’t allow the soil to dry up as quickly as clay or terracotta pots, so I advise using those instead. You must use the right soil for your cactus covered. Use soil that doesn’t retain a lot of water. You’ll need soil that drains well and dries out rapidly after irrigation.

Depending on the native habitat of your cactus, you can either use commercially available cactus soil or make your blend. You’ll need soil that combines fine sand, grit, and mud if the species thrives in the desert.

The ground required by a cactus that thrives in a tropical climate will change. Therefore, try to precisely resemble the soil characteristics seen in the cactus’ natural habitat.

– Correct Watering Technique

Overwatering is one of the main issues with cacti. Cacti are quite sensitive to overwatering because they have a high drought tolerance. Since most cacti can survive without water for approximately a month, underwatering is less of an issue.

Generally speaking, before watering the cactus, make sure the top inch of the ground is dry. Dip your finger in the container to ensure your cactus isn’t receiving too much water.

According to how quickly the soil will dry, you could have to water your cactus every week or every other week. Allow the soil to absorb the water completely before removing any extra that seeps into the saucer.

It should go without saying that the bottom of your pot should include drainage holes so the dirt can dry out more quickly. While regular watering will gradually destroy the roots and make the entire plant mushy to the touch, overwatering won’t immediately kill your cactus.

Once this occurs, it will be unable to reverse the situation, and your cactus will die from a lack of water. This is a common mistake that people make with the golden barrel. 

Therefore, overwatering your cactus will prevent it from growing and cause it to die. Even if your plant appears to be thriving well at the moment and exhibits no symptoms of discomfort, the excessive moisture environment you’re producing can eventually result in irreparable harm.

– Optimal Temperature

Cactuses typically grow best in warm climates if you want them to grow faster you need a warm climate. It is usually between 65 and 80 degrees Fahrenheit. In the winter, they may endure temperatures between 45 and 55 degrees Fahrenheit on the lower end of the temperature threshold.

Your cactus won’t grow as quickly if you don’t maintain the proper temperatures, particularly if it is exposed to lower temperatures than what is advised in the growth stages.

Nevertheless, certain cacti will be more tolerant of cold than most cacti. Echinocereus viridiflorus, a green floral hedgehog cactus, can withstand temperatures of 20 degrees below zero Fahrenheit.

So another element that may encourage or inhibit the growth of your cactus is temperature. Additionally, you must maintain your cactus in its ideal temperature range if you want it to grow quickly enough.

– Provider Fertilizer

Although they don’t need to be fed frequently, cacti can occasionally benefit from a good fertilizer applied sparingly. Only fertilizing once a year, or at most twice a year, in the spring, summer, and fall will be sufficient to cover all of the plant’s nutritional needs.

Provider Fertilizer

Cactus plants will benefit from a small amount of nutrition when actively growing, but more frequent feedings are not necessary.

Avoid overfeeding at all costs because it’s just as harmful as overwatering. As you can see, various factors can either promote or inhibit the growth of your cactus. However, having a healthy cactus is ultimately more crucial.

– Proper Germination

There are methods for promoting your cacti’s ideal growth, just like with another indoor plant of course, not the least of which is the proper environment. Most of the time, you’ll buy your cactus from a nursery and won’t have to bother about the seedling stage. 

However, if you decide to try growing a particular kind from cactus seed, you will have to be prepared for germination, they must be covered, but not for too long that it prevents them from breathing.

You can keep your seedlings as content as possible once they have been potted, or after getting that new one home, as you would pick a sturdy container. The best choice is usually terracotta or clay pots with drainage holes to avoid damp soil and moist roots.

Choose a pot that is three to four inches wider in diameter than the cactus so you won’t have to report it as frequently, and it will have room to flourish. Next is to use soil that drains effectively. To ensure the plant receives the right nutrients for growth, use a potting mix designed specifically for cacti or succulents. 

Choose a spot that experiences regular temps and lots of sunlight. Cacti adore the light because they are desert-adapted plants. Windows facing south are excellent choices for a room between 65 and 80 degrees Fahrenheit because it is still germinating and it needs this boost, so this step is very important. 

Another influential factor to remember is to not overwater these plants. Most cultivars can be irrigated using the soak-and-dry technique only when the soil is entirely dry. 

A pot with sufficient drainage will also aid in avoiding this problem. Finally, make use of a fertilizer designed for cacti. You can always get a cacti fertilizer to aid in providing extra nutrients during the active growing season. Simply make sure to adhere to the instructions on the container.


How To Choose Cactus With the Best Growth Rate?

Since there are so many options, choosing the best cactus plant for your house might be a little overwhelming. After all, there are around 2000 different types of cacti worldwide.

Knowing what you want from the cactus is crucial when choosing the proper kind. Are you searching for a cactus that can provide lovely floral displays, a nice piece of decor, or a plant to treasure and watch develop for the next 20 years?

A wonderful starter plant for growing indoors is the Barrel cactus, which belongs to the genus Echinocactus. These don’t require a lot of water, just a lot of light. As little as once every two or three months of irrigation is sufficient for the Golden Barrel cactus to grow. 

You may expect them to grow by around an inch yearly, even with such little water. In the wild, these cacti will eventually bloom in the summer with tiny yellow flowers, but only when they are about 20 years old.

Numerous varieties of cacti in the Ferocactus family grow to an average height of 2-3 cm each year and are frequently used as indoor plants. These will resemble the Golden Barrel cactus and have the same distinctive barrel form. 

They favor strong sun and little water, like the majority of cacti. Once they reach maturity, these cacti can also produce flowers in various colors, such as pink, yellow, purple, or red, depending on the species.

The Saguaro cactus comes to mind when you visualize the well-known desert setting. With a lifespan of more than 200 years and a height of over 75 feet, they are an excellent choice for growing inside due to their sluggish pace of growth.

Depending on the growth stage, these cacti typically grow between an inch to six inches annually. However, a Saguaro cactus may not flower for up to 40 years.

How Much Will a Cactus Grow in Ten Years?

You must have experienced a lot in the past ten years, don’t you think? But, unfortunately, with a cactus plant, it’s essentially the same. During this time, the normal cactus plant expanded from a tiny, immature plant to a mature, fully grown plant.

It’s likely that it has experienced both good and bad times and has endured circumstances that would have killed most other plants. However, it also underwent ten growth eras, each providing an opportunity for significant growth.

How Much Will a Cactus Grow in Ten Years

Some species, like the majority of Gymnocalycium cacti, don’t grow faster. However, these cacti will grow to their greatest height before the age of ten. Other species, such as the San Pedro cactus, can grow several meters tall.

Cacti have extended by several inches over a decade, with some species reaching astounding heights of up to 1.5 meters. Given the right circumstances, most cacti will flower at least once over a decade.

Which Cactus Plants Grow the Quickest?

You could want to acquire a kind of cactus recognized for growing faster than the rest if you enjoy watching your plant kids develop as much as we do. Other succulent growers have told us that Cereus and Trichocereus cactus species grow especially quickly.

Beautiful blue cacti of the species Pilosocereus are recognized for their rapid growth. Visit the article we just wrote about them to find out more information! Although most cacti grow slowly, their growth is worth the wait, which is a bit of a nuisance.

The “Totem Pole Cactus (Pachycereus Schottii Monstrosus)” is a different variety of cactus to get you enthusiastic about. Even though Pereskia resembles a typical bush rather than a cactus, it is a cactus species.

Pereskia grows like trees or shrubs and doesn’t have as thick of stems as typical cacti. Although most Pereskia only grows to a height off five to seven feet, they grow quite quickly and reach a height of 20 feet. Even though they start growing quickly, they will slow down once they reach a height of about two to three feet.

– Pereskia vs Pereskiopsis

However, Pereskia likes to bloom frequently, and its flowers are lovely, unlike most other cacti. Furthermore, since they both belong to the same genus, Pereskiopsis, and Pereskia, they are quite similar. They resemble the Pereskia and grow extremely quickly as well. 

However, compared to most cacti, pereskiopsis have stems that are smaller and have limbs that reach leaves growing along the main stem.  They can grow taller up to 20 feet tall and are remarkably hardy and swift-growing.

Despite not looking like traditional cacti and not liking prolonged droughts, the Pereskiopsis and the Pereskia are both members of the genus of cacti.

What Are Some Easy Cactus Varieties for Beginner Gardeners to Grow?

One of the simplest varieties of cacti to grow is the lovely blooming orchid species Epiphyllum oxypetalum. With adequate room and the right conditions, it can reach up to a height of 10 feet and have gorgeously colored leaves.

A more popular variety of cactus is the barrel cactus. As seen in the picture above, they begin spherically and develop upward into a cylinder or “barrel” shape. They are available at most gardening supply stores and are ideal for novices. 

The lovely Hoya Heart Cactus or the Hoya Kerrii is ideal for Valentine’s Day. It only needs well-draining soil, some exposure to direct sunlight, and water every three to four weeks. As a result, this variety of cactus is low maintenance.

Another common variety of cactus is the Opuntia or prickly pear cactus. Indoors, prickly pears grow well. You can even plant it in your yard, where certain types can reach enormous heights if your winters are mild. It makes a great drought-tolerant landscaping plant for those who reside in dry climates. 


Cacti are a species of flora that will take time to grow and serves the following purposes:

  • When you have adjusted your plant in the proper environment, with the right needs provided, it will grow annually to its given significant rate.
  • In order to provide the right boost for the new seedling, you must germinate it properly.
  • Your cacti will soon grow healthy and bigger by providing them with the type of environment they like, which is the environment of a desert: hot and dry.

Therefore, you can plant some faster-growing varieties if that is what you are after doing some research.
