A mixture of two parts sand, two parts gardening soil, and one part perlite or pumice yields the best results when mixing the three components. This translates to 3 cups of sand, 3 cups of soil, and 1.5 cups of perlite or pumice when expressed in cups. Pumice or perlite is used to help with aeration and drainage.
How may soil be improved for succulents?
A succulent potting mixture cannot be made in a single, ideal manner. Whomever you ask will give you a different recipe. One component may be prefered over another by some gardeners. Additionally, some gardeners completely forgo using specific ingredients.
Here is a straightforward method that has worked for me to create your own succulent mix:
Combine potting soil and perlite in equal amounts (1:1). Equal proportions of each ingredient should be blended. Feeling the soil when it’s wet is a good technique to make sure it has the right texture. When squeezed, it should crumble and break apart. If it solidifies and lumps up, more perlite or inorganic material is required.
Another easy method for creating homemade succulent potting soil:
Mix two parts of potting soil by volume with one part perlite and one part gravel. The components should be thoroughly mixed. Wetting the soil is a fantastic technique to see if your soil mix contains the right ingredients. When squeezed, it should crumble and break apart. More inorganic components are required if it congeals into a lump.
Potting soil for jungle or tropical cacti:
To make a base potting mixture, mix peat moss and ground fir bark in equal amounts. Mix one component of coarse builder’s sand with two parts of the potting foundation (2:1). The components should be thoroughly mixed. (This mixture is only appropriate for tropical cacti that prefer a little more moisture, like Christmas cactus.)

Succulents and old coffee grounds: good or bad?
The decomposition of the used coffee grounds will enrich the soil with nitrogen, a crucial component for succulents. Along with improving drainage and aerating the soil, they may also reduce weeds and deter pests.
How To Grow Succulents | Succulent Plant Care Info
Sempervivum, Jovibaraba, and Sedum are winter-hardy plants that can grow in zones 3–9.
Light:
The majority of succulent species require from half a day to a full day of direct sunlight. It is advised to find some afternoon shade in particularly hot places. Succulents planted in excessive shadow will extend outward in search of more sunlight. Enough sunlight will help succulents grow into gorgeous, vibrant plants.
Planting:
Plants should be gently removed from their containers and planted, making that the soil level is maintained at the same depth as it was in the container.
Keep in mind that most of our plants came straight from the cold frames where they were shielded from the harsh sun and drying winds. For the first week, give your plants and garden décor some shade and cover to gradually adapt them. Every few days, extend the length of the day by a few hours. This will make it possible for a smooth transition.
A layer of pebbles or pea gravel sprinkled on the soil surrounding the plant will be beneficial to your succulents. Additionally, it is highly ornamental.
Soil:
Succulents require soil with good drainage. Make sure the place has good drainage and is not in a low region that would remain wet before planting in the garden. You can buy cactus soil for container gardening or add sand, gravel, or volcanic rock to your potting soil for enhanced drainage. You should have a drainage hole in the container you are using for planting, or you can fill the bottom of the container with crushed rock before adding the planting medium. Spreading gravel or tiny pebbles on top of the ground can add a lot of style.
Watering:
After planting, water the area thoroughly and wait a short while before watering again. Wet feet bother succulents, who don’t like them. Water whatever you do thoroughly. They will require less water once they are established.
Fertilizer:
Succulents generally require relatively little fertiliser. During the growing season, they only require monthly watering and a balanced fertiliser.
Flowering:
Each type of sedum blooms at a different period and in a variety of pink, red, and yellow hues.
After the second or third year, Sempervivums will flower. From the middle of the main rosette, which has a cluster of flowers, a flower stalk will emerge. Sempervivum blooms are open, starry, and typically pink. They are carried above the plant on a stem with several blossoms. Fortunately, there are always chicks born earlier from the base that grow in a ring around the mother plant to continue for subsequent years. The monocarpic crown that generates the flower head dies off after flowering. Twist the stalk off gently once the blossom fades, then plant a chick where it was.
Winter maintenance:
Typically, established succulents in the garden do not require winter protection. Snow frequently provides protection for chilly locations. Balsam boughs can be used as a light winter mulch in cold climates without snow cover, but this is typically not necessary.
Shipping:
When your plants are delivered, gently open the package as soon as possible. Once you have unpacked your things, water your plants properly and let them drain well because we ship plants on the dry side. Early-spring shipping succulents could have some dry edges and a lacklustre appearance. This is typical, and their colour will deepen when exposed to sunlight. Sempervivums change colour with the seasons, and each variety has a certain time of year when it is at its most vibrant.
Uses:
Succulents can be used in countless planting scenarios. The most interesting containers and troughs are those with a variety of colours, textures, and behaviours. Succulents make lovely plants for rock gardens. There is always colour since there are so many different bloom times.
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, mould, or other diseases are removed, effectively sterilising 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 centres.
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 emphasise 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 favour 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 because to its great water retention ability. 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 fibre 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 fertilise your plants frequently if you intend to utilise 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 utilising it, especially if you intend to use it for potted houseplants.
