Unfortunately, gravel cannot support succulent growth because it lacks the necessary water and nutrients.
However, drainage issues that might cause yellowing or death in succulents can be resolved with the use of pebbles and gravel. Potting pebbles are the name for these rocks. By placing them in the bottom of the pot, you can stop water from standing in the soil and rotting the roots.
Now, if you’ve ever seen a succulent arrangement that appears to be growing solely in rocks or gravel, the gardener really put some soil to that area first. It won’t likely be as much soil as the succulent requires, but it will be enough to keep the roots covered and supply it with a sufficient amount of nutrients.
Succulents can they grow without soil in gravel?
Because they can retain water in their leaves, succulents can grow without soil. As a result, they may go for extended periods of time without having access to surface moisture.
But in order to do so, they need to have access to a sizable quantity of water and nutrients from the environment.
Succulents can typically grow in rocks without soil or water. The goal is to have a rock that makes it simple for water and nutrients to absorb.
The inability to continuously providing succulents with what they require when they are grown in rocks without soil is one potential drawback.
There are several advantages to soil, such as the provision of air spaces that can absorb excess moisture or dryness more effectively than would be possible with merely rocks.
Because there are no open spots on top where insects could enter and destroy this plant’s root structure, it also safeguards against pests and illnesses.
Another problem with growing succulents in rocks devoid of soil is that they might not be able to resist drastic changes in weather.
When there are no other plants nearby to provide shade, this plant has nothing to shield it from environmental variables like wind or water that could blow sand into its leaves.
We advise staying with potting soil unless you are certain of the environment your succulent will thrive in.
It offers all the advantages required for this kind of plant, which cannot be achieved by just utilizing rocks as a substitute.
Can succulents be grown 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.
Can succulents live in the absence of soil?
Does soil help succulents grow? Without soil, are succulents able to live in terrariums? Can succulents grow on driftwood, moss, sand, pebbles, or rocks?
These lovely bouquets are something we frequently see. Succulents can be found in almost any container you can think of. The container’s WOW factor will increase the more unique it is.
Part of the appeal and enjoyment of potting and creating a beautiful arrangement is the search for the most unusual and implausible container for succulents. And they are very lovely and beautiful to look at. However, I frequently hear the query “Can succulents live in these arrangements without soil?”
Even without soil, they will persist. Will they prosper, though? Only briefly. Consider these to be enjoyable, short-term tasks that aren’t meant to last for a very long period.
Even though they resemble epiphytes, succulents have quite different growing requirements and habits. Plants known as epiphytes grow on the surface of other plants and obtain their nutrients from the sun, rain, and other environmental factors. Orchids and air plants are two examples of epiphytes that are well-known.
With the exception of tropical or seasonal cacti, which are considered epiphytes by nature and have different growing requirements from desert cacti (Christmas cactus is a prominent example). Succulents are frequently discovered in the wild in places where other plants would not typically grow.
Most originate in arid regions, deserts, and semi-deserts. Rain forests and mountainous areas are home to others. These plants have become exceptionally resilient and adaptive to environmental conditions that are typically too harsh for other plants to survive, such as high temperatures and low precipitation.
Natural habitats for some succulents include arid lakes and seashores, which, because to their high concentrations of dissolved minerals, can be harmful to other plant species. Succulents are adapted to hard environments by nature due to their native habitats, which are less than optimal. This is why it seems difficult for most plants to survive even a few days in these arrangements, but succulents can live for a very long period.
Succulent plants’ capacity to hold water is another quality that makes them suitable for these soilless systems. Succulents are drought resistant because they have tissues that store water. Typically, the leaves, stems, or roots of these plants serve as water reservoirs.
They have evolved to withstand the extreme aridity. They do not require a constantly moist soil or frequent watering to survive.

Top Dressings
In your succulent pots, AVOID using moss. Although it is attractive, it retains moisture and fosters fungi and germs. Additionally, stay away from non-porous rocks like glass marbles, pea gravel, river rocks, fish rocks, sand, etc. As long as the soil has enough air to breathe, you can put a few rocks here and there as ornamentation.
USE TOP DRESSINGS THAT ALSO SERVE AS DRAINS. Shale, Turface, and pumice are my top choices. The Supplies page is a list of my shopping sources.
DO NOT utilize containers without drainage holes unless you only intend to use them for a short period of time. This applies to terrariums, jars, bowls, and mugs. And no, you cannot use them if you first fill them with soil and then place pebbles on the bottom. This fosters the growth of the bacteria that causes rot.
If there isn’t a hole in the bottom, drill it. If the container is non-porous or glazed, you should make enough holes with a ceramic or glass bit to allow the soil to dry out fast. Use a piece of screen, burlap, garlic net, or anything else that will keep the dirt in yet enable it to completely drain for larger holes.
Light
If your succulents aren’t used to full sun, DON’T expose them to it. Most people prefer part-sun over bright indirect sun. A succulent can be burned and killed when moved from partial to full sun.
Give your succulents as much light as they can handle, but do it gradually. Put your plant in a spot that receives a little more sun than it usually does, then move it over the course of a week or more to a brighter spot. Shelves, gardens, and windows facing north will all receive less light than those facing west. South receives a wonderful combination of east and west sun, while east-facing receives morning sun.
DON’T base the frequency of your irrigation on a schedule, but rather on how dry the soil surrounding the roots is. You could wish to repot in a different container with better draining soil if the soil doesn’t dry out within a week.
DON’T rule out using a smaller, more quickly drying pot. The best clay is unglazed and has drainage holes. Improve your soil by adding more drainage components than organic ones.
DO NOT use pre-bagged potting soil with additional fertilizer as it frequently lacks the proper nutritional balance for succulents and contains an excessive amount of organic material that causes the soil to dry out too rapidly.
DON’T use anything but ordinary topsoil and a ton of drainage materials. Brown organic dirt should be present in the same quantity or less than the other ingredients. On the Care Guide page is my formula for soil.
DON’T assume the soil your plant was grown in is the best soil for that kind of succulent. Before bringing any plants home, make sure to check them for fungus and pests. Avoid purchasing plants that were housed with ill or infected plants, as well as those that have been treated with neonicotinoids or other insecticides that are harmful to the environment.
DO check the plants you’ve picked and the surrounding plants for insects and fungus before taking them inside. If necessary, and especially if the soil was moist when you acquired it, repot your succulents in good soil. Take care not to expose them to more sun than they are used to. Start with some light exposure and progressively increase it over the course of a week or longer.

How should gravel be watered for succulents?
While each plant has a different need for light, most thrive in bright indirect light.
Gravel dish gardens are a good place for small Sempervivum and Crassula succulent species to flourish.
Thick, fleshy leaves on succulent plants serve as water reservoirs. Some types just produce gorgeous stems and leaves, while others yield flowers. Because too much moisture might cause the plants to rot, most succulents prefer dry environments to flourish. For the majority of succulent cultivars, rocky soil with good drainage works well. Although some soil is still required to supply nutrients and a medium for the succulent roots, you may grow them inside in a container filled with gravel that adequately drains moisture.
A one-inch layer of gravel should be added to a 3- to 5-inch-deep pot or dish. Use a dish with no drainage holes at the bottom.
Over the gravel layer, scatter a tablespoon of powdered activated charcoal. With charcoal, odors are prevented from growing in the moisture that is held in the gravel layer.
Over the gravel, add a peat-based potting soil, filling the dish to within 1/2 inch of the rim. Make your own mix instead by mixing two parts peat and one part compost.
The soil layer should be wetted until it is completely saturated. To determine the moisture content, stick your finger into the soil mixture.
Succulents should be planted in potting soil. Place them so that the depth at which their roots are buried is equal. The amount of space needed will vary on the particular plant species, but often 2- to 4-inches should be enough.
When the top layer of potting soil is totally dry, water the succulents. Just enough moisture should be provided to mildly dampen the soil. The soil’s gravel base is where the extra moisture drains.
Succulents can be cultivated in pea gravel.
Although I’ve discovered a technique to grow some of my indoor succulents in containers without drainage, it is ideal to plant succulents in a container with a drainage hole. Succulents essentially require well-drained soil to survive. If the plant’s roots are left in water or damp, they will grow mold and perish.
The secret to growing succulents in containers without drainage holes is to first fill the container with pea gravel before filling it with soil. By doing so, a drainage-like effect is produced that prevents the roots from becoming saturated with water.
Although I was dubious at first, the succulents in two plates I placed in my kitchen window without drainage holes have survived for well over a year and are still thriving. (I know, the ones in the pink dish really need to be transplanted; they have grown so much they don’t actually fit in it any longer.)
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 fertilizer. During the growing season, they only require monthly watering and a balanced fertilizer.
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 lackluster appearance. This is typical, and their color will deepen when exposed to sunlight. Sempervivums change color 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 colors, textures, and behaviors. Succulents make lovely plants for rock gardens. There is always color since there are so many different bloom times.
