Whether buying it or making it yourself, plant cacti in specially formulated potting soil. Cactus care requires good drainage, and standard potting soil has a tendency to retain too much moisture for these low-water plants. Cactus soil mixes come in a wide variety of brands—some are even marked as organic—and you can make your own quite easily.
Horticultural sand, cactus compost (you can use standard potting soil for this, but remove any large pieces of wood or twigs), and grit in the form of pumice, perlite, or porous gravel are a suitable combination for cactus soil. Before planting, properly combine the materials.
If you’re growing cacti in a terrarium, you should first add a layer of gravel to the bottom of the container before covering it with potting soil.

How to Grow a Cactus in a Container
- When you grow a container garden, consider more than just the flowers.
- Find a container first.
- Pick a shallow container because most cactus have short roots and limited growth.
- Step 2: Include gravel and potting mix.
- The bottom of your container should be covered with a thin layer of gravel or tiny stones.
- Set up your plants.
How are cacti planted in the ground?
Many claim that before beginning to grow cacti and other succulents, they could never keep plants alive. These plants are trying to live. They are typically simple to grow as long as they have good drainage, lots of sunlight, and protection from freezing temperatures. They are also evergreen, pest- and disease-free, and drought tolerant, making them attractive in the garden all year long. The list of top cacti and succulents for your Western garden is provided below, along with some of our most important advice for making your cactus garden a success.
The Best Varieties to Grow
There are numerous varieties that give appeal to your yard, such as agaves, aloes, and barrel cacti. See our picks for year-round, low-maintenance beauty.
Transportation
Cactus should be wrapped in heavy carpet padding or foam while being brought home from the nursery. This guards against harm to both the plants and your skin. Make sure you also wear gloves.
Protection
Wearing thick leather gloves will shield your hands while you are working with cactus that have spikes. Some gardeners advise putting on two pairs of gloves—one pair of rose gloves and one pair of leather work gloves.
Plant Wisely
Similar to any other plant, cacti and other succulents can be planted. Create a hole that is 1.5 times as wide and as deep as the root ball. Take the plants out of the pot (wearing protective gloves and safety glasses). Put your plant within the opening. If necessary, you can fill the hole with granulated succulent and cactus plant food and mix it with the soil for the backfill. With well-draining modified soil, fill up the area surrounding the plant. Lightly tamp down the earth and moisten it. Spring, late summer (if your region gets freezes), or early fall are the best times to plant (in warmer climates).
Give Them Some Space
Make sure you allow those tiny succulents and cacti you bought at the nursery plenty of room because they can grow into big plants. Many also generate pups or offspring that grow into clumps resembling colonies.
Drainage
A cactus can rot or die if it receives too much moisture. In order to monitor the soil’s moisture content and ensure that your cactus isn’t receiving too much water, stick your finger a few inches into the soil. There is no need to water if there is any moisture. Make sure your irrigation system also stops watering during rainy weather.
Potting
Use pots with drainage holes on the bottom for potting succulents or cacti. To assist prevent the drainage hole from being clogged, fill the bottom of the container with fragments from broken pots or a lot of pebbles. When planting, make sure to use a cactus mix that contains pumice since it improves drainage. Rocks can be used to create a beautiful impact and to keep soil in place.
Watering
Water plants on a regular basis using a drip system twice per week. Water can be used in very small quantities. Then hand water plants as needed in warm months.
Succulents and cacti still require sufficient water every three to five days until the plant roots are developed. Make sure to water your plants or check that your irrigation system is getting to the roots if there isn’t any rain.
After the first year, water less. You don’t need to water plants as frequently once they’ve established themselves. After the first year or two, many succulents and cacti can even stop receiving irrigation entirely. If they only receive rain, they will live and frequently thrive. Especially in the fall and winter, avoid watering.
Fertilizing
Although fertilizing succulents and cacti is not required, some gardeners do it because it can promote faster growth and better flowering. A popular liquid plant food that may be applied in the spring and fall is Grow More Cactus Juice. It’s also acceptable to dilute the mixture before applying it if you fertilize frequently. After fertilizing, water the plants.
Provide Protection in Freezing Temperatures
Many cacti and succulents may survive in temperatures as low as 25 to 30 degrees without suffering any harm. However, some plants, such the ocotillo and Yucca rostrata (big bend yucca), can withstand temperatures as low as zero degrees. If your garden frequently experiences cold weather, be sure to choose hardy species or grow plants in containers that can be brought within for the winter.

Cacti and succulents can now be found in many different places. Start at a nursery in your neighborhood. There’s a good chance they have a good assortment or can guide you to a speciality grower.
How can I get my soil ready 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.
What is the ideal environment to grow cacti in?
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.
Can several cacti be planted together?
Numerous succulent plants may be cultivated inside, and several of them rank among the easiest to maintain plants. They are actually excellent houseplants for novices, but as with any type of horticulture, you have to know what you’re doing and dealing with to grow them well.
The stunning Nopalxochia ackermanii and the abundant blossoms of the Epiphyllums (orchid cactus), as well as the unusual and fascinating Astrophytum asterias (sea urchin cactus) and the hairy Cephalocereus senilis, all create excellent displays of cacti and succulents (old man cactus). It’s unfortunate that these plants are not grown more frequently! They are not picky and can withstand most abuse, with the exception of excessive indulgence. Overeating is to blame for those who are rotting and squishy on windowsills or for those that are sitting around all dusty. They require plenty of sunlight, clean air, and a cool, dry place to rest during the winter.
Large flowers and a tendency to trail characterize forest cacti. They are ideal for hanging basket displays because of this. The desert types can be highlighted in a group presentation since they have unique shapes and textures. It works wonders to place a number of cacti or succulents in a single, larger dish. Larger plants like agaves and aloes look their best in individual pots.
A cactus or succulent garden can be created in any large, shallow pot. You want to choose plants with similar maintenance requirements that are all roughly the same size. All of these plants need a lot of light, so check that the container you choose can be placed next to a window. The cactus in the pot have a beautiful, yet dry surface thanks to a covering of fine grit over the compost. To emphasize the desert effect, scatter tidy pebbles among the plants.
Some cactus look lovely arranged in a row of little pots. Gymnocalycium mihanovichii mutant cultivars are excellent in this regard because they have variously colored heads.
How far apart can cacti be planted?
Let’s now discuss some justifications for why you might allow your succulents a little more room to expand.
As you would have anticipated, there are several advantages and disadvantages to planting succulents farther apart as opposed to putting them closer together. The fact that your succulents will grow larger more quickly is one of the main benefits of putting them a little more widely spaced.
This is a really nice alternative if you’re not as concerned about how tight the arrangement appears, and how properly planted and close together everything is from the get-go.
Because they have more room, your plants will grow bigger and are more likely to delay having children or experience new growth.
Additionally, you’ll discover that you won’t need to keep the arrangement up as frequently. You won’t feel the urge to prune back or eliminate portions of the plant to make the arrangement appear as though it is properly occupying the area because there is more room for them to flourish.
Additionally, it is simpler to water this kind of arrangement and ensure that the roots are thoroughly moistened. It will be much simpler to deliver water to the roots if you pour it straight on top of the plants or directly into the soil below them.
Downsides to spreading out your succulents
The fact that the arrangement frequently doesn’t appear as complete or striking right away is one of the major drawbacks of spacing succulents farther apart.
Using a decorative rock as a top dressing is a fantastic method to combat this. Between each of your succulent plants, you could place a really lovely rock to make the arrangement look finished and more polished. The beautiful thing about this is that it merely enhances the appearance of the arrangement while not preventing your succulents from growing.
You won’t immediately notice as much growth in the succulent itself if you plant your succulents too widely apart since too much space will force the succulent to send out roots.
If you want to give your succulents room to grow, I suggest placing them in a pot or with other succulents approximately 1/2″ to 1″ (13 mm to 25 mm) apart. Give them another 1/2 to 1″ from the pot’s edge as well.
The final drawback might not actually be a drawback, but you could be tempted to purchase additional succulents to fill in the spaces created by the gaps between those succulents!
What kind of soil should you use to grow cacti?
Contrary to most movie sequences, cactus flourishing on pure sand is not a positive thing. A rocky, nutrient-rich soil kept in a well-draining pot or container is what desert cactus, also known as Opuntia cactus or hairy old man cactus, prefer. Ascertain that nutrients such peat moss, coconut coir, pumice, perlite, or vermiculite enable a suitable balance of the soil’s aeration and drainage qualities.
Avoid using forest goods like wood chips and pieces of pine bark and instead start with a base of regular potting soil. Pumice, a light-weight and porous volcanic rock, should be added in two parts. In the absence of those materials, you can use vermiculite, perlite, NAPA oil dry number 8822, aquatic plant soil, non-soluble cat litter, or chicken grit. This component is essential because it provides adequate aeration and allows water to move through your potting mix fast.
Add some coconut coir lastly. This breaks down gradually, adding structure and aiding in the cactus mix’s ability to retain moisture. In contrast to peat, it is also wettable and does not compact during the wetting process.
Cacti Soil For Jungle Cactus
Both lithophytic and epiphytic cacti are fairly universal in the jungle. In other words, they can grow on rocks or rely on the nearby trees to live.
Such cactus species
The orchid cactus has the unusual capacity to obtain its daily requirements from the air as well as from dead leaves or other detritus left in crevasses and fissures.
Therefore, you’ll require a potting mixture containing oak leaf mold, pumice, coconut coir, peat moss, bat guano, and some orchid bark or fir bark to replicate the jungle cactus’ natural growing environment.
Epiphytic cactus require potting soil that resembles that used for desert cacti. After that, you’ll need to make some adjustments.
- Pumice, 1 part, to lessen soil compaction
- coarse orchid bark in two pieces
Compared to simply adding extra ordinary potting soil to the mix, this provides better aeration properties. But with time, the bark degrades and eventually turns into soil, indicating that it is time for repotting.
These are merely a few good cactus potting soil examples that you can use. Of course, the ideal mixture will vary depending on the sort of cactus you want to cultivate, and you’ll also need to prepare the other two key growth settings, namely water and light.
Making your own cactus soil mix is fun in part because you can experiment to see what works best for your favorite succulent and cactus plants.
