How To Plant Cactus In A Pot

Pick a shallow container because most cactus have short roots and limited growth. You don’t need a particularly big or deep pot.

Do cacti require special soil?

Cacti, with their striking shapes, textures, and vibrantly colored flowers, are excellent houseplants since they thrive in the normally warm, dry indoor environment and don’t need much care. Cactus plants are simple to cultivate indoors, especially if you start out with the correct potting soil.

How much soil do cacti require? Cacti require a potting medium that is porous, sandy or pebbly, offers lots of airflow, and has great drainage. Additionally, a good cactus potting mix should have some organic material that, when moistened, makes moisture available to the plant roots but quickly dries up.

How far down in a pot should a cactus be planted?

The pot or container you choose for your cactus is crucial and might have an impact on the health of your plant. We will discuss many best and worst cacti pots and containers in this article. We’ll also discuss the advantages and disadvantages of various pots and the significance of size and shape.

Cacti and their growth are significantly influenced by the type of container, its form, and size. While some containers are ideal or excellent, others are completely inappropriate.

Importance of cacti pot/container shape

Before we discuss container materials, let’s discuss another crucial aspect. Take care of the container’s form while buying one for your cactus. When purchasing a planter for your cactus, some qualities to consider include the following:

The size of the container should be similar to that of the cactus. This is so that, if planted in a large container, cacti’s roots, which are frequently not very long, will remain in the middle of the container.
Cacti grow well in cylinder, short, and square pots. Avoid selecting containers that are overly deep, tall, or small.
All of the dirt in the container should be “used” by your cactus. Therefore, there shouldn’t be an excessive amount of dirt that the cactus roots can’t penetrate. Only leave enough room around the plant for growth and drainage in the bottom.

Size of pots for your cacti

As we’ve already established, your cactus, and more specifically its roots, should practically be the same size as the pot. The best plan is to take your cactus outside and examine its roots before selecting a pot or container. Remove a cactus from its current container, examine the roots, and measure them.

Your cactus needs a wide container if its roots are short but growing to the sides, and a deeper container if its roots are long and spreading outward. Additionally, you’ll need to give room for drainage, so a pot should be just a little bit deeper than the roots.

To make your cactus comfortable in the pot, while picking a pot, add around 1-2 inches in width (to your plant’s full width). Depending on the type of cactus you choose, the depth of the container should be between 4 and 7 inches. Cylindrical cacti, for example, have lengthy roots, whereas other varieties have shorter roots (such as ball cacti).

Ceramic terracotta or glazed ceramic pots/containers for cacti

Among the advantages of ceramic planters are:

Pots made of ceramic are sturdy and weighty.
Ceramic pots come in a variety of styles and colors, many of which are glazed, making them a great option for ornamental settings.
Ceramic pots’ porous nature prevents water logging or accumulation (provided you have potted your plants in the right soil mix).
They are lovely and stunning in any environment.
They are appropriate for the colder months when it is not as heated outside.

Several drawbacks

Terracotta planters in particular are porous and minimize water buildup, however this can be detrimental to young seedlings and plants. This indicates that the soil will dry up more quickly, especially if you leave your cactus outside and during hot weather. You can forget about it, but frequent watering can also cause the pH of the soil to rise. In the section on selecting soil for cactus, we talked about how the pH of the soil should be acidic. However, larger plants thrive in ceramic containers.
To avoid having to drill the drainage holes yourself, make sure the ceramic pots include them. Drainage holes are necessary, but they might not be present in all ceramic pots.
Cactus roots may not penetrate the soil completely and instead focus on the sides. This occurs as a result of the ceramic container’s water evaporating quite quickly and leaving behind mineral residue on the sides. The roots of cacti lean to the sides in an effort to reach these minerals, but they can only burn themselves because the sides of the planters heat up.
Ceramic pots are more likely to develop mold.
Ceramic utensils may crack (especially with children or pets).

Make sure to choose the appropriate size and shape when selecting a ceramic planter. This set of three ceramic planters for small plants serves as an illustration of a ceramic pot or planter for your cacti.

Plastic pots/planters/containers for cacti

Plastic planters are another kind of container that is excellent for growing cacti in.

benefits of using plastic containers to cultivate cacti:

Plastic containers are portable and lightweight, making them simple to transport.
Less watering will be needed to maintain soil in a plastic container because it will dry out more gradually. In comparison to ceramic pots, this means fewer watering sessions.
Cacti do well in plastic pots since they don’t overheat easily and can retain heat even after the sun has set. Because most cacti don’t enjoy quick temperature drops, this is a useful feature.
The low cost of plastic pots offers an additional benefit.
To avoid waterlogging, most plastic containers feature numerous drainage holes. Additional holes can be drilled if necessary.
The roots of cactus do well in plastic containers because they spread out uniformly across the soil. This is because roots won’t lean to the sides of a plastic container since water won’t evaporate through the sides. Additionally, the acidity of the soil will last longer.
The likelihood of mold formation is decreased.
Both little and large adult cacti do well in plastic containers.
If you bang on them from a table or windowsill, they won’t break.

Hanging containers for cacti

For your cacti, you can also choose hanging basket pots. Smaller or larger trailing cactus can grow in hanging pots. Additionally, you can use them to indoor or outdoor adorn your home. Make sure your hanging pot has drainage holes and perhaps a saucer to catch any water that may drip from it as many hanging pots lack these features. These particular plastic pots allow you to drill your own holes in the bottom.

Bad containers for growing cacti

Let’s start by stating that growing cactus in glass pots is not recommended. A cactus terrarium is often made in a glass container. This is not the same as letting a cactus develop for several years. Cacti do not appreciate humidity or waterlogging, thus terrariums are not the best environment for them.

Glass cactus containers have several advantages.

For a special occasion, you may assemble a lovely terrarium with cacti and take the plants out right away (maximum of 2-3 weeks). If you’re making cacti terrariums, only use open glass containers. Plant cacti together only if their requirements are comparable. For making a cactus terrarium, you can add decorations like colored sand, shells, and figurines. Utilizing small, recently-planted cacti is the best option.

Cons of using glass cactus containers:

Glass containers are very unlikely to have drainage holes, which can lead to water logging and a buildup of moisture. This will result in root rot, which will ultimately kill your plant. You must exercise caution and give your plant some water each day, but doing so runs the risk of preventing water from penetrating the soil completely and reaching the roots.
Even an open terrarium is susceptible to fogging up and having an elevated humidity level within. Cacti require sufficient airflow and detest humidity.
Your cactus won’t be able to absorb water from the rocks in the bottom layer of soil if the dirt is layered. Roots cannot obtain water from rocks, and neither can rocks absorb it.
A glass container’s sides will quickly heat up and may burn your cactus and its roots. Your cactus may actually be cooked to death if you put it in a terrarium out in the sun.

Metallic containers for cacti

Cacti cannot be grown in metallic pots. This is due to the possibility that rusting metallic containers could seriously harm cactus.

Additionally, metallic containers quickly experience excessive heat and cold, and cacti detest abrupt temperature fluctuations.

Conclusion: Ceramic (terracotta and glazed), plastic, and hanging (may be ceramic or plastic as well) pots are the ideal containers/pots for growing cacti. Glass containers should only be used temporarily (or not at all), and metallic pots should be avoided.

How should a cactus be planted correctly?

According to Fine Gardening, cacti thrive in regions with full, all-day sunlight and very well-drained, sandy soil. Planting next to a south-facing wall enhances the cactus’ ability to reflect additional heat and sunlight in mild climes.

To the same depth as the cactus root system, dig the new planting hole. Depending on the size and kind of the cactus, you should normally space it from other plants at a distance equivalent to that plant’s width. In the hole, plant the cactus. To settle the earth around the roots, completely fill the hole and water it. For about four weeks, keep the soil just moist enough to allow the cactus to establish itself in its new place.

What kind of potting soil is ideal for cacti?

With little effort on your side, buying pre-made cactus soil guarantees that it includes everything the cactus needs. Perlite, pumice, sand, and gravel, in the proper proportions, are included in pre-made cactus soil, along with a negligible amount of peat moss or coco coir.

However, you also have the option and it’s simple to make your own cactus soil mix! Combine two parts perlite or pumice, three parts coarse sand or gravel, and three parts potting soil. Use caution when using fertilizer-containing potting soil blends because they can scorch cacti roots and promote lanky growth.

How often should a cactus be watered?

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.

Can a cactus be planted in a pot without any holes?

Whether you’ve planted succulents before or not, you probably already know that the subject of drainage holes comes up very frequently. What makes drainage holes crucial? They help prevent moisture from accumulating at the pot’s base by allowing extra water to seep out of the container.

Because succulents store water in their tissues, leaves, and stems, this is a significant concern. They are vulnerable to root rot if submerged in water for an extended period of time. Some folks are rigid about all planters having drainage holes.

Some people don’t care as much about holes. Here are some things to think about if you have a container that you really want to use for growing succulents and cacti but you’re worried about drainage problems.

To Drill or Not to Drill?

You can certainly drill a hole into the planter, and you don’t need to be skilled with tools to do so. How to start drilling a hole in ceramic, glass, etc. is covered in a ton of free video tutorials. Please click on “How to Grow Succulents in Pots without Holes” for detailed instructions on how to drill a hole in glass or ceramic containers.

Things to Consider Before Drilling a Hole

What would drilling a hole cost you? Would it be more expensive to buy a pot with drainage or to drill a hole? Most households already have a drill.

Most likely, all you need to spend money on are some reasonably priced diamond drill bits. When you consider how much use you will get out of a drill, even if you don’t already own one and must buy one, you might view the purchase as a wise financial decision.

You must decide which item you value more, the plant or the pot. You might want to think twice before drilling a hole in a particularly expensive pot that you spent a lot of money on or perhaps an antique. Additionally, once a hole has been made in something, there is truly no going back; it is irreversible.

So think about which is more essential to you: the plants’ value or the container’s value. Succulent plants are fortunately inexpensive and simple to replace. The reason we adore them so much is that they are extremely simple to cultivate and spread.

Do Succulents Need Drainage?

Succulents in pots—can they thrive without drainage? In light of this, you’ve made the decision to plant the succulents in a container without holes. How long will they be able to survive? Succulents can live and even flourish in pots without holes, so yes, they can. Everything hinges on how you take care of the plants.

The main issue that individuals have is with irrigation. Succulents can suffer from people overwatering them, which is bad for the plants. Succulents can flourish for a long time in pots without drainage after you understand how to properly water them.

Here is evidence that succulents can thrive in containers without drainage for a long time. In this instance, the container failed much earlier than the plants. The containers of these plants have outlived them. The plants are still flourishing, as you can see. They spent around two years in this container. How did I manage to keep them around this long? primarily from utilizing the right potting material and adequate watering practices.

I’ve attempted to repair this in the past with hot glue. I decided to repot these plants after around two years.

How to Plant Succulents in Pots without Holes

You can make a layer for drainage in the bottom of the pot by adding a layer of rocks, pebbles, stones, or pumice (or a combination of these). By allowing extra water to flow out of the soil and into the rocks at the bottom, this can help prevent root rot. By enabling the water to drain from the soil more quickly and keeping the roots from spending too much time in moist soil, this helps prevent root rot.

Think about how big the pot is. You will primarily need pebbles, pumice, or smaller rocks if your pot is small. You’ll need bigger and more rocks the bigger the pot.

You can incorporate pebbles, boulders, pumice, or perlite into the cactus potting mix in addition to the drainage layer. Adding larger particles to the soil, which is typically highly compact, generates more space between them, allowing water to drain out more quickly and preventing the roots from soaking in damp soil for an extended period of time.

The aid of activated charcoal aids in water absorption. Additionally, it has inherent antibacterial qualities that can inhibit the growth of germs and fungi. A layer of activated charcoal, about 1/2 inch thick, can be added over the rock layer or in the bottom of the pot.

Although it is optional, activated charcoal is a nice choice to have if you want more drainage and absorption. It might not be possible to utilize activated charcoal if the pot you’re using is small. Please visit my resource page to learn where to buy activated charcoal online.

You’ll need extra dirt as the container gets bigger. More soil indicates that the soil can hold more water. Consider the plants you are utilizing while selecting the pot size.

Large containers are unnecessary for small plants. When repotting, it’s a good idea to keep in mind that the new pot shouldn’t be more than 1-2 inches larger in diameter than the old one. Succulents don’t require a lot of extra space because they prefer a small pot anyway.

How to Water Succulents Without Drainage

Your watering strategies are the key to the plants’ survival in pots without holes. Keep in mind that extra water cannot drain from the pot, so water the plant sparingly. You should take particular care when watering plants without holes if you tend to overwater your plants. In between waterings, let plants dry out, then check the soil for moisture.

Use a syringe, a spray bottle, or a squeeze bottle if you want to better manage the water you put into the containers. Make sure to spray the soil, not the plant’s surface, while using a spray bottle. You want the water to reach the plant’s roots so that it can be absorbed there.

The size of your container, the growing season, and the environment where you reside all have a significant role in when and how often you should water. The dry and growing season tends to increase the need for water on plants. Plants require less water during the slower growing season and cooler months. I normally observe the plant to determine when and how frequently to water it. In general, I water once every 7 to 10 days throughout the summer and less frequently, once every 10 to 14 days or more, during the cooler months.

My plants receive plenty of sunlight because I keep them outside the entire year. Additionally, my area is rather dry, and the midday sun may be quite warm. You don’t need to water as frequently if you reside in a humid climate.

Water the plants sparingly to begin with and then increase the amount as necessary. Until you determine the plants’ watering requirements, it is preferable to underwater rather than overwater.

If you mistakenly added too much water, you can carefully tilt the pot over while holding the plants in place to prevent them from falling out to drain the extra water. To dab the extra water, you can also use a dry towel or paper towel.

If you keep your plants outdoors, be sure to transfer the pots without holes to a shaded area when it looks like it could rain. Pour away the extra water as soon as you can if you forget to move the pots and it rains on them.

When your plants begin to shrivel, that’s a strong indication that they need more water. Usually, the leaves are the first to do this. You are typically underwatering if you touch a plant and it feels soft and unfull of water.
