- 3 components of potting soil
- coarse sand in two pieces (turface or poultry grit)
- Perlite, one part (or pumice)
Which type of soil is best for 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.
For succulents, what should you add to standard potting soil?
The proportion needed to make top-notch potting soil for succulents. 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.
How is the sand used for succulents?
It is true that creating your own succulent soil requires a little more work. However, it’s an excellent approach to achieve the ideal soil mix for your specific variety and growing circumstances while also saving money. Consider this to be an all-purpose, universal recipe. It may be modified depending on your environment and the materials available and will function both inside and outside, in containers or in the ground.
Mix one part organic ingredients from the left column with two parts mineral components from the right to create a balanced succulent soil. You can choose from either side, or you can combine other elements. Make sure the volume is made up of 2/3 mineral materials and 1/3 organic matter.
Observations regarding a few of the stated soil options:
Potting Soil
On the market, potting soil comes in what seems like countless variations. Check the components to ensure that you are getting exactly what you ordered and to determine whether it aids in drainage or moisture retention. Do not use peat-based potting mixtures (more on that below).
Gravel
Look for particles with a diameter of between 1/8″ and 1/4″. Fine dust particles that might clog soil pores and hinder drainage are removed by rinsing. Instead of layering gravel at the bottom of a non-draining pot where it can cause rot, you should incorporate it into your soil.
Other Mineral Possibilities
You can use equal amounts of diotamaceous earth, chicken grit, decomposed granite, non-soluble cat litter, and oil dry (both of which are made of calcined molasses clay).
Can I use standard potting soil to grow succulents?
In their natural habitat, succulents will flourish in sandy soil or even gravel. With this kind of soil, the succulent never has wet feet since the water can drain through.
- If you only have potting soil on hand, adding crushed stones or coarse sand will be essential because succulents demand well-drained soil.
- A succulent soil must be able to store nutrients and water and then release them when the plant requires them.
- To breathe and easily pierce the soil mixture, the roots need air pathways in the soil.
- A healthy soil should hold the succulent plant upright, encourage root expansion, and anchor the roots.
- A good succulent mixture should not contain an excessive amount of nitrogen because this will result in huge, leggy leaves.
Succulents can they grow in garden soil?
One thing you should know up front if you’re looking for the tried-and-true, fail-proof best soil for succulents is that no two seasoned succulent gardeners use the same succulent potting soil. It’s like to attempting to get talented chefs to agree on the best handmade biscuit recipe; despite the fact that they all utilize the same fundamental components, each of them has a unique touch that they all fervently adhere to. Most of them also perform flawlessly.
Consider the arid environments with little to no seasonal rainfall where natural succulents and cacti can be found. Succulents have evolved to survive with only a small amount of water at a time. Their stems and leaves can retain this water for weeks or months at a period, and their roots are particularly effective at quickly absorbing water. Consider arid deserts, bare mountainside fissures loaded with weathered grit, and sparse tree limbs at the border of dense rainforests.
Succulents typically need soil that is slightly different from garden soil in order to survive; otherwise, they will rot. Succulent soil must be able to support the plants physically, store a small amount of moisture and nutrients, and drain flawlessly to prevent plant damage from excess water, especially in rainy places.
For hardy landscape succulents, what you use in the garden will probably be very different from what you use in containers. To better accommodate various plant kinds (such as cold-tolerant Alpine, tree-dwelling epiphyte, or real desert plants), local weather conditions, the need for watering (or lack thereof), and even container size, specialists frequently create somewhat varied succulent potting mixes.
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 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 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.
Before repotting succulents, should you water them?
Repotting a succulent is necessary if its roots are cramming the container or if it needs to grow larger for any other reason.
Early spring or early fall, just before their growing season begins, are the ideal times of year for repotting succulents.
Since they can only remain in a pot for two years before beginning to exhibit signs of potted fatigue, which can eventually result in root rot and other issues, repotting should always be done at least every two years.
Before being repotted, succulents need to be watered for a few days to allow them to dry out.
This is due to the fact that when you water them, they do absorb moisture, and that should give your succulents’ roots enough time to absorb all possible moisture before being replanted.
Additionally, it is important to do this to give them time to become used to their new pot and soil, which is a little bit drier than their previous environment.
Your succulents must dry out for a few days before you may clear the old soil from the roots with water while repotting them.
