What Size Pot For Cactus

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.

Which container is best for cacti?

Although there aren’t many distinctions between terracotta, clay, and ceramic pots, understanding what they do differ can be useful.

The earthy reddish color of terracotta pots is just a result of using a different kind of baked clay that includes more iron.

Terracotta Pots

The finest containers to use for your succulents, cactus, and other indoor plants that prefer to dry out between waterings are made of terracotta.

Because terracotta is a porous material, it is very permeable, allowing for significant airflow and allowing the soil to breathe.

However, clay pots do something even more important: they stop root rot by removing excess moisture and water from the soil, which stops your plant’s roots from becoming damp and decaying.

These pots are great because they have a consistent, cylindrical shape and aren’t too deep. I found them on Amazon.

These pots are adorable and have tiny feet so they are elevated up a little bit for something a little more beautiful.

Additionally, this kind of pot would look great in a mid-century modern or boho-chic setting.

The only drawback of utilizing clay pots is their fragility and weight. Take a little more care when relocating them.

They may deteriorate more quickly if kept outside because of the fluctuating temperatures and added moisture.

Above all, cultivating succulents and cacti in terracotta pots gives desert landscapes their distinctively beautiful appearance.

Succulents and cacti are the ideal plants for terracotta pots, but other plants like pothos, sansevieria, peperomia, hoyas, and zz plants can also grow well in these pots.

Other moisture-loving plants, such as tropicals, can be potted in terracotta containers, but you will need to check the plant’s water requirements more frequently.

Clay or Ceramic Pots

Your succulents will do quite fine in clay or ceramic pots as well. Use of glazed ceramic should be avoided because it will prevent your pot from breathing, trapping extra moisture.

Does cactus pot size matter?

Your cactus or succulent plant’s survival depends on the pot size and soil type you choose.

In this section, you will learn how to pot or repot your plant, how to knock out a plant, and how to manage prickly plants, as well as everything else you need to know about properly caring for your cactus or succulent plant.

When they’re young, succulents and cacti can be kept in a dish garden. For a start, the common clay bonsai trays are excellent.

The plants can be moved into their own pots when they become too large. No matter the temperature—45°F or 85°F—the plants will remain the same size if you keep them dry. The plants will rot if you water them in cold weather or when they are dormant.

Avoid overpoting. Rotting roots are frequently caused by overpotting. Put the smaller pot into the larger pot and fill the area in between with gravel if the plant is top heavy. This will provide the plant with a sturdy foundation without putting it at risk of decay.

Pot Size

Cacti and other succulents should be potted in the smallest containers possible. Use a pot for cactus that is just big enough to accommodate the plant. Use a pot that is just a little bit bigger than the root ball for other succulents.

The drainage provided by the holes on the pot’s bottom is insufficient for some plants. Make the hole in a clay pot bigger by using a hammer and a screwdriver. For a plastic pot, use a hot knife or hot ice pick.

In either scenario, take care to avoid burning yourself or breaking the pot. If the clay pot does crack, save the fragments for your subsequent planting endeavor rather than throwing them away.

Soil

The potting material is less significant than excellent drainage. A thick layer of gravel or crumbled bricks should be put over the porous soil. More humus (organic matter) is preferred by spineless succulents in their potting soil.

We typically use the terms “heavy,” “organic,” and “light” to describe different types of soil. These definitions mean as follows:

Heavy. This is composed of clay, loam, or good garden soil with roughly one-third humus. It should contain roughly one-third washed builder’s sand or perlite where good drainage is necessary.

Organic. This is humus-rich soil, leaf mold (decomposed leaves), or some other organic material-rich soil. The drainage will be improved by using perlite or coarse builder’s sand.

Light. This describes a material with an open texture that has great drainage and can be kept damp but never wet. Plants that spend time in trees in the natural world benefit from it.

How to Pot

1. Choose a pot that is not excessively huge.

2. Fill the bottom with enough drainage material.

3. Insert your potting material into it until it is roughly one-third filled.

4. Check the plant’s size (make sure it won’t be too high above the pot’s top or too far down in the pot). Unless the plant prefers to move horizontally, in which case it should be placed at one edge, place the plant in the middle.

5. Fill all the crevices between the plant and the pot with your potting medium while holding the plant gently where you want it to stay.

6. Shake the pot to help the soil settle, then gently press the earth down around the roots. Add extra soil if there isn’t enough or if it starts to pack down. Older plants get more earth packed around them than seedlings do. So that there is room for water, leave a space between the top of the medium and the top of the pot.

7. Give the plant water.

Repotting

The process is essentially the same when working with plants that are already potted, with the exception that you must start by taking the plant out of pot 1.

Sometimes the plant can be readily removed, but other times it can be more difficult. Do not pull on the plant if it is stubbornly refusing to emerge from the pot. The container breaking can be preferable to the plant being damaged or having its top broken off.

How to Knock Out a Plant

If the plant is stuck in its pot, try gently tapping the pot against something hard, like wood or concrete, to see if you can squirm it out.

If it doesn’t work, try carefully slicing the inside of the pot with a knife to see if the plant will now emerge.

If that doesn’t work and the pot is made of clay, use your hammer to smash it with a few controlled strokes that won’t harm the plant.

Take part of the soil around the root ball out once the plant has been removed from the pot. Prune away a portion of the roots if they appear to be overgrown.

You can take a knife and simply chop off the outside of the root ball, including the roots, on some plants where the roots become extremely, extremely thick. If you wish to retain your plant in the same-sized container, you can also utilize this root pruning technique.

You can keep your plant “growing on” in the same container for years by first cutting some of the roots and then portion of the top.

How to Handle Spiny Plants

Handle prickly plants by wrapping them in a narrow band of newspaper. Using the band like a belt or harness, wrap it around the plant. For each plant, use a new band.

Gloves are uncomfortable to handle because the small spines break off inside the glove and the huge spines stab right through the glove.

Actually rather simple to propagate are cacti and other succulents. Learn everything you need to know about successful plant propagation in the section that follows.
