Regular potting soil from your yard won’t work for succulents since they need soil that drains. Select cactus soil or potting soil that has been mixed with sand, pumice, or perlite. Be gentle when repotting because succulent roots are extremely brittle.
What kind of soil is ideal for planting succulents?
Succulent soil is the basis for a plant’s ability to thrive, whether you are planting succulents outside or indoors. Larger soil particles are necessary for succulents to have a well-draining soil that allows water to enter quickly and drain away from the roots without compacting the soil. Use a soil test kit to verify the ideal soil for succulents and adjust the soil to a pH range of 6.0 to 6.5 before planting.
- Succulents prefer well-draining soil and have short root systems.
- The ideal soil is one that is nutrient-rich, loose, and rocky.
- Use a potting mix designed specifically for succulents and cacti when planting in containers, and place the plant in a pot with drainage holes at the bottom.
- Succulent plants could die off if their soil is too alkaline.
- Add soil amendments to the existing soil to make it more suitable for succulents’ needs.
Succulents can be planted directly into the ground.
Succulents can be planted in pots, the ground, or a combination of the two if you want them to flourish outside. Make careful to provide your succulents six to eight inches of soil designed for succulents when planting them in the ground.
This will give the roots enough of room to spread out and grow without being constrained by dampness. Make holes for the succulents after spreading the soil, then plant them there and cover the holes with earth.
The succulents should then be lightly watered to help them stay in place. If you want your succulents to stretch out and become larger, keep in mind that they will expand; therefore, avoid planting them too closely together. Direct-planted succulents and succulents in bowls or pots work well together to create levels and offer another element to your garden.

What ingredients go into succulent soil?
My recipe for succulent potting soil is as follows:
- 3 components of potting soil
- coarse sand in two pieces (turface or poultry grit)
- Perlite, one part (or pumice)
Can you plant succulents in just rocks?
It should be obvious that succulents will thrive when planted in rocks given these circumstances. They drain very well and do not retain water, which eliminates the possibility of root rot. This does not include another component of soil, though, since all plants need nutrients.
Although succulents are not particularly hungry plants, they do need certain nutrients to grow. Other micronutrients like zinc or iron are needed in smaller levels, whereas macronutrients like nitrogen, phosphorous, and potassium are essential. The plant won’t grow at all or last very long without these nutrients.
By their very nature, rocks don’t release nutrients quickly enough to keep the plants alive. They are composed of minerals, but since they decompose so slowly over time, they are not appropriate for growing on their own. Additionally, they often don’t retain enough moisture, allowing the roots to quickly dry out after draining practically instantly.
Sadly, this means that succulents cannot thrive permanently without soil in rocks. If not given regular care, they may survive for several weeks or even months on the nutrients found in the stems and leaves.
Succulents can be planted in sand.
Yes, succulents can grow on sand, to put it briefly. In fact, it’s rather usual to see stunning succulent arrangements that have only been planted in sand. And the overall aesthetic appeal is enhanced when the sand itself is a wonderful color.
Think of it as a quick project if you decide to plant your succulent in sand.
Do succulents grow better in the ground or in pots?
All cacti and succulents require sufficient drainage to keep their roots from rotting. No matter where you decide to plant your succulents, you’ll need to ensure sure the proper kind of soil is used and that there is a method for any extra water to drain.
Succulents in containers undoubtedly benefit from better soil. You can pick the right kind of soil and a container with a drainage hole when you plant a succulent in a container. Drainage holes are obviously not strictly necessary, although they are advised.
The ability of succulents and cacti to drain excess water depends on the type of soil they are placed in. If you reside in a warm, dry climate, your soil might already be suitable for cultivating cacti and succulents. If not, before planting succulents you might need to make improvements to your garden or landscaping.
Is it better for succulents to grow in the ground or in pots?
For succulents cultivated in the ground versus succulents in pots or other containers, different types of potting material are needed.
Our nursery is located in Australia’s Blue Mountains, west of Sydney. The land has very poor soil and is covered in huge rocks and sandstone. This sort of soil is extremely hard when it doesn’t rain, and when it does, it becomes like a thick, sticky mud. However, the succulent gardens we have established over the years are doing rather well, especially in times of heavy rain, in this really poor soil.
The succulent plants that flourish in our gardens need to be mentioned in one or two places. First of all, many types never reach their full size because they don’t grow very quickly. On the plus side, the color is more vibrant—even in the summer, when most succulents lose their color—than ever. Smaller and more compact plants come from the growth, which is also much more fat.
The gardens are either elevated or have a slope, which aids in water drainage on rainy days. We have never had a succulent decay because it was in water-soaked soil over a protracted rainy spell.
However, if the soil is poor, they will develop slowly and little. We think that succulents planted in the ground will thrive in just about every soil type.
The root system will spread more easily and the succulents will grow bigger and faster if you add potting soil (any potting soil will do for the garden succulents) that will bring in nutrients.
The notion that succulents don’t require much room since their roots aren’t large or deep is one I’ve read several times, but it’s just not true.
Succulents will always expand their roots out in quest of nutrition if given the opportunity. This is also the reason why succulents grown in the ground or in soil are much hardery and simpler to manage than plants cultivated in containers.
They also tend to be less bothered by little pests like scale, aphids, and mealy bugs. Garden succulents have a large amount of space to grow and can send their roots far below to stay cool in the summer and warm in the winter.
What about succulents that are grown in pots with regular garden soil? That’s not such a good idea, I guess. Although many succulents will live (and many will also pass away rather fast), they won’t likely have a very attractive appearance, will be more vulnerable to pests and diseases, and they could pass away suddenly.
Plants in containers do not have much room for their root systems to look for food, and the temperature is constantly changing. In the summer, a pot can get very hot, especially if it’s a deeper color. This would effectively roast the succulent alive.
Small pots in particular can have their roots choked by dense garden soil. Succulents thrive in soil that is home to a variety of creatures and small animals in the ground, but these same organisms are unlikely to flourish in containers. For attractive, contented growth, succulents in pots require high-quality, freely draining potting soil.
How frequently do succulents need to be watered?
During the months that are not winter, when the temperature is above 40 degrees, you should water your succulents every other week. You should only water your succulent once a month in the winter (when the temperature falls below 40 degrees), as it goes dormant at this period.
A few situations constitute an exception to this rule. Because their tiny leaves can’t hold as much water as other varieties with larger leaves, some varieties of succulents need to be watered more frequently. In the non-winter months, feel free to give these small leaf succulents a water if they appear to be thirsty. When they are thirsty, succulents generally exhibit a wrinkled appearance. But always keep in mind that being underwater is preferable to being overwater.
Do succulents require sunlight?
Succulents generally require at least 4-6 hours of sunshine each day to thrive. They enjoy being in places that are sunny and bright. Lack of sunshine will cause difficulties in succulents such elongation or etiolation, when the plants extend for more light. Weak stems and low growth are the results of this procedure. Lack of light causes succulents to lose their bright coloring and turn pale or back to a drab green tone. Plants that receive enough sunshine will display their whole spectrum of brilliant hues, showing their genuine beauty.
What serves as perlite’s replacement?
Different perlite substitutes will function better or worse depending on the plants you are growing and the circumstances in which they are growing.
Below, we’ll examine the ten most popular alternatives to perlite.
- rice stalks
- Pumice
- Agricultural tenacity
- granular granite
- Vermiculite
- charred clay
- Bark
- Peat
- Coir
- Sand
Rice husks
PBH rice hulls or parboiled rice husks are excellent substitutes for perlite in soil mixtures. If you’re searching for an organic, greener option, they’re also perfect. When they are parboiled, any weed seeds, mold, or other diseases are removed, effectively sterilizing and killing the rice seed at the same time.
Lightweight rice husks (also known as hulls) aid in soil aeration, drainage, and compaction prevention. Because they are organic, rice hulls are a fantastic source of nutrients for plants and are safe to add to soil for both indoor and outdoor gardening.
The main drawback is that they tend to float to the top of the soil when watered because they are lighter than perlite.
Pumice
Given that both pumice and perlite are porous rocks created by volcanic eruptions, they are quite similar to one another. When comparing “perlite vs. pumice,” many gardeners can become extremely enthusiastic, but the truth is that pumice has a number of advantages over perlite.
It doesn’t float during watering or blow away in the wind because it is heavier, on the other hand. In addition, pumice, unlike perlite, creates less dust, especially the coarser kinds, and contains more nutrients and minerals. Additionally, it does a superb job of maintaining the soil’s airiness, pliability, and drainage. Pumice is by far your finest option if you’re cultivating succulents.
Pumice, on the other hand, is more expensive and can be challenging to locate at most plant nurseries or garden centers.
Horticultural grit
A typical size range for the little stone fragments that make up horticultural grit is 2 to 4 mm. It works similarly to perlite by forming air pockets inside the soil, which gives the roots oxygen while preventing root rot because of better drainage. Grit creates less dust and may be used for both indoor and outdoor plants because it doesn’t contain any lime.
Additionally, it is heavier than perlite, which makes it an ideal ornamental layer for potted plants, particularly if you need to ward off fungus gnats. Succulents, outdoor alpine plants, and lavender respond best to horticultural grit.
Horticultural grit is heavier than perlite, which is a drawback. However, you can make use of this by incorporating it into the soil mixture to balance top-heavy potted plants.
Granite gravel
Perlite and granite gravel have a similar appearance and serve comparable functions in soil mixtures. Both are porous rocks, which are excellent at retaining moisture. They also maintain the soil aerated, well-drained, and free of compaction. Gravel is heavier than perlite, and unlike perlite, even little bits, like pea gravel, won’t wash away during irrigation.
Granite gravel is a perfect option for adorning the topsoil of potted plants because of this, in addition to using it as a garden ornament. In fact, spreading gravel over the surface of the soil can aid with weed management and is a terrific way to aerate and improve the drainage of muddy or clay-rich soils in your garden.
Granite gravel is not a perfect substitute for perlite, mostly because of its weight. It will make potted plant soil mixtures considerably heavier, so use pea gravel instead for smaller pots, especially indoors. Gravel is also a poor choice for germination since immature plants will find it difficult to push through due to its weight.
Vermiculite
Vermiculite is a mineral that is extremely absorbent and is used in both indoor and outdoor gardening. It is lightweight, pH-neutral, and does not degrade like perlite. Additionally, it enhances soil structure and aeration.
When used in pots, vermiculite absorbs water and nutrients and holds them in the soil for later use. Vermiculite is actually a far better substitute for perlite if you’re growing plants that require consistently moist soil because it is considerably more absorbent. It is also the best medium for seed germination.
The high absorbency of vermiculite is both one of its benefits and disadvantages. Vermiculite, in contrast to perlite, does not produce a good soil media for plants like cacti and succulents that dislike having their roots constantly moist. Vermiculite is not a good substitute for perlite if you’re seeking for a well-draining potting soil mix.
Calcined clay
Calcined clay is a soil conditioner that is frequently sold under the Turface brand name. It’s probably been used on sporting fields, but it’s also a fantastic substitute for perlite. Although calcined clay is far more absorbent and can hold its weight in water, both are pH neutral and great at retaining moisture.
Cacti and bonsai trees benefit greatly from its ability to maintain the soil’s aeration and improve drainage, making it a wonderful addition to potting mixes. Additionally, because calcined clay is heavier than perlite, watering does not readily wash it away.
We recommend calcined clay without reservation, but we must emphasize that it needs to be replaced from the soil because it will begin to degrade after a few years.
Bark
One of the key ingredients in commercially available potting soil mixtures is bark, particularly pine bark. It aids in soil drainage, keeps soil from being compacted, holds onto water, and gradually distributes nutrients into the soil, depending on its size.
Keep in mind that compared to perlite, fine bark has a lesser air permeability. Because it is organic and biodegradable, bark is a great growing medium for moth orchids and may be used for both indoor and outdoor cultivation.
The most important thing to keep in mind if you’re thinking of using bark in place of perlite is that it is more acidic than the pH neutral perlite, which ranges between 7 and 7.5. The pH of pinewood bark, in particular, ranges from 4.0 to 5.0. If you’re planting magnolias, ferns, carnivorous plants, or other plants that do well in acidic soils, this can be a great benefit. However, most plants favor a pH range of 6.0 to 8.0.
Peat
Peat, which is also known as sphagnum moss, is a great component to soil mixtures. The soil is kept moist for extended periods of time thanks to its high water retention capacity. It helps prevents the soil from being compacted, keeps it aerated, and retains nutrients and minerals because of its fibrous nature.
For growing tomatoes, blueberries, rhododendrons, and other acid-loving plants, some gardeners and houseplant enthusiasts even go as far as completely substituting peat for soil.
Bark and peat both have an acidic composition. Check the soil pH requirements of the plants you intend to grow before deciding to use peat rather than perlite. Another thing to note is that even though peat is biodegradable, mining for it damages the local ecosystems where it comes from and is not environmentally friendly.
Coir
Coir, often known as coco coir, is a fiber made from the husks of coconuts. It has a texture that is pretty similar to peat moss, and gardeners are using it more frequently because it is easier to create. However, how does it contrast with perlite?
Both coir and perlite are lightweight, help with drainage, and increase air permeability by dissolving dense soils. Coir is a wonderful choice for plants that need moist soil since it has a larger water retention capacity than perlite and, unlike perlite, has a higher ability to absorb nutrients and release them into the soil.
There’s a good reason why coir is frequently suggested as an alternative to perlite instead of peat moss: coir has an acidic pH range of 5.2 to 6.5. Remember that coir has little to no nutrients, so you will need to fertilize your plants frequently if you intend to utilize it as a growing medium on its own.
Sand
Sand may be used in place of perlite, depending on how coarse it is. Sand and perlite are comparable in that they both promote drainage, are pH-neutral, sterile, and are devoid of nutrients. While sand initially absorbs water, it does not hold onto it like perlite does over time, especially the coarser forms.
One of the greatest options for garden soils, particularly clay-rich or highly compacted ones, is sand. Instead of using the extremely fine sand seen in playgrounds for children or construction sites, you should use coarse sand that is around 1.52mm broad.
Remember that sand is significantly heavier than perlite when utilizing it, especially if you intend to use it for potted houseplants.
