The use of pumice as a soil additive for succulent plants has gained a lot of popularity thanks to one excellent pumice provider, General Pumice Products.
Pumice is considerably more durable than perlite, as was already noted, so if you’re using a more organic soil, I definitely recommend adding some.
Succulents can also be planted in pumice alone, but you’ll need to be cautious about how frequently you water them.
Pumice is incredibly porous, and the many holes that make up each particle collect water. Pumice, which is similar to the gritty mix in that it allows for more ventilation around the particles, doesn’t “feel” damp like typical potting soil and can be beneficial for succulents.
It does, however, hold a lot of water, so you should wait until it is totally dry before watering your succulents once more.
Succulents enjoy pumice, right?
Cacti and other succulents want soils with good drainage.
Pumice enables enthusiasts to mix the perfect soil to balance watering frequency and drainage rate.
The choice of grade in pumice soil allows for simple management of drainage rates: larger grades (stones) drain more quickly and hold less moisture than smaller grades. To achieve perfection, grower-blended grades are used when necessary.
How is pumice used with succulent plants?
Improve drainage by amending beds with a mixture of 25% garden soil, 25% pumice, 25% compost, and 25% sharp (large-grain) sand such as decomposed granite for succulents and other plants that can’t sit in damp soil.
Plant fat euphorbias and other cactus-like plants that hold moisture and are particularly prone to rotting in berms that have been 50 percent pumice-amended. Fill the planting hole with pumice to enclose the roots and prevent the plant’s crown from touching the earth if amending the soil in a garden bed is not an option.
To absorb rainwater that pools around plants, topdress with pumice. Use a metal rod or broom handle to create a circle around the plant with vertical tunnels (air holes) that are several feet deep for succulents and other plants that are in danger due to soft, wet soil. Place them around that far from the plant’s base and 12 to 18 inches apart. (It is intended to add pumice to the soil without harming the roots.) To make it simpler to funnel pumice into the holes at soil level, enlarge the perforations there a little.
How much pumice should I add to the soil of my succulent plants?
Mix 25 percent pumice with 25 percent garden soil, 25 percent compost, and 25 percent large grain sand to increase drainage for plants like succulents. For plants like some euphorbias that are prone to rotting, amend the soil by adding 50% pumice, or in place of amending the soil, fill the planting hole with pumice so the roots are completely covered.
Which is better for succulents, perlite or pumice?
In potting mediums, pumice and perlite both make gaps for water and air. Neither does, in contrast to vermiculite, a different soil improvement. Adding one-fourth to one-third perlite or pumice to the potting soil makes it much harder to overwater plants like succulents, which require great drainage. Pumice is a better material to use for plants if the plant is tall since its weight can help keep the pot from tipping over.
Pumice and perlite both add air spaces to the soil and aid in drainage, however depending on the use in the garden, there may be slight variances between them that favor one over the other. Pumice is a heavier substance than perlite, according to Central Texas Gardener, and as a result, it doesn’t float or blow away as easily. In addition, pumice lasts longer than perlite. On the other side, pumice could be more expensive and more difficult to locate in the market, especially crushed for blending with soil.
What makes perlite and pumice different from one another?
Ever pondered the nature of the tiny white particles in your potting soil? Most of the time, they are pumice or perlite. Pumice is a soft, insert-mined stone that frequently originates from Oregon, whereas perlite is a mined siliceous rock that is heated and inflated, or “popped like popcorn,” into a white lightweight substance. Being screened for consistency and having the finer particles removed makes Black Gold Perlite and Black Gold Pumice highly appealing.
As porous rocks, perlite and pumice are both added to potting soil to enhance aeration and drainage. A potting soil’s ability to retain moisture and nutrients will also be improved by the addition of perlite and pumice. Similar to peat moss, they serve as reservoirs for water and nutrients, storing them until the plant needs them.
Pumice gives potting soil bulk density because of its weight. When you are growing plants in outside containers and you don’t want them to topple over in the wind, this quality is advantageous. Because it offers excellent aeration and aids in root encapsulation, pumice is frequently the aggregate of choice for speciality potting soils (cactus, bonsai).
Perlite serves as a component of potting soil mixes and is a superior neutral media for germination of seeds and cuttings. Additionally, it can be used to hold bulbs and is a crucial component of hypertufa planters.

Volcanic rocks are considered to be excellent for soil, but which is better for plants: pumice or lava rocks?
In terms of horticulture, lava rocks and pumice have a lot in common. They both help your soil’s structure, which enhances drainage and airflow. The advantages of lava rocks make them superior in that they are more affordable, more accessible, and have other advantages.
To how much potting mix should I put pumice?
- Pumice can be added to any horticultural soil mixture in amounts as low as 10% and still have positive effects.
- Use this for up to half of your potting soil medium for growing succulents.
- You have the option of using it right out of the bag or activating or supercharging it first by saturating it with nutrients and advantageous bacteria. Before adding your pumice to your garden soil, simply let it sit in a nutrient solution, such as compost tea, for at least 24 hours to activate it.
What kind of soil is ideal 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.
Which soil combination is ideal for succulents?
You’ll need containers that can accommodate the quantity of succulent soil you intend to mix and have room for it to be tossed around a bit.
- The potting mix for succulents works well in a sizable tote with a top.
- Use your hands, a trowel, and a garden fork to mash up the soil.
- Long rubber gloves are usually what you should wear to prevent skin irritability and dryness.
Mix It Up!
half a pot of soil
The opposite half:
- 1/3 fine sand
- 1/3 pumice or perlite
The remainder should consist of roughly two thirds coarse sand, one third perlite or pumice, and one third poultry grit or turface.
Should pumice be washed?
Use these guidelines to properly remove your tough skin. Stop using the pumice stone right away if you start to feel discomfort or other strange symptoms.
Preparation
- assemble all of your resources in one location. Make sure your water and stone are both clean.
- Spend five to ten minutes soaking your calloused, dry skin in warm water. Your skin’s tough surface will soften as a result. For more softness and moisture, add soap or an oil to your water. Apply the pumice stone in a warm bath or shower if you’re using it on your elbows, knees, or face.
Using the pumice stone
- Put your pumice stone in warm water and soak it at the same time as your skin. Never apply your skin to a dry pumice stone. Your risk of damage will decrease because a damp pumice stone can easily glide over your skin.
- Take the target area out of the soap wash and use a towel to pat it dry. Before patting your skin dry, soak for a few additional minutes if your skin is still harsh.
- Apply the pumice stone to your skin after removing it from the warm water.
- Apply light pressure as you move the pumice stone’s abrasive side in a circular motion over your skin. For two to three minutes, give your skin a massage. Stop applying pressure as soon as your skin starts to feel sensitive or irritated because you’re probably applying too much.
- Pay special care to the sides of your toes, the heels, and any other dry places you may identify on your feet.
- Once the dead skin has been peeled off and the softer skin underneath is visible, keep rubbing the pumice stone over your skin.
- Rinse your skin after two to three minutes of gentle massage. Repeat this procedure if you’re still noticing dead skin patches. To keep the surface clean, cleanse your pumice stone after each use.
- To keep your skin soft and supple, you can repeat this procedure everyday or a few times per week.
Finishing up
- Apply a moisturizer or oil to your skin afterward to preserve moisture and keep it supple. After hydrating your skin, slip on moisturizing socks for an extra boost.
- Each time you use a pumice stone, clean it. Scrub the stone’s dead skin off with a bristle brush while it is submerged in running water. To make sure it’s clean and dirt-free, use a small bit of soap. On the surface, bacteria can flourish.
- Do not distribute your pumice to others. Each member of the household ought to have one.
- Let the stone dry naturally. To stop bacteria from growing, place it somewhere dry and away from moisture.
- Boil your pumice stone in boiling water for five minutes to thoroughly clean it. Keep it away from damp areas and let it air dry.
- Over time, your stone will deteriorate and become too smooth to be useful. Replace your stone if it starts to get too tiny, smooth, or soft.
Pumice has an acidic or alkaline pH.
A healthy soil needs an adequate amount of water and nutrients, as well as little compaction to facilitate smooth gas exchange. Transporting carbon dioxide and oxygen to and from the surface is necessary for plant roots. Due to its porous nature, pumice enhances soil quality by allowing nutrients to be stored in the tiny holes and allowing water and gases to easily pass through the pores. Because the rock particles in pumice are inorganic, little compaction and no decomposition take place. This inorganic rock also has the advantage of not attracting or harboring fungus or insects. In horticulture, drainage is crucial, and the presence of pumice makes tillage considerably simpler. Utilizing pumice also produces the best circumstances for growing cacti and succulents because it improves water retention in sandy soils and lowers density in clayey soils to facilitate greater gas and water transfer. Because plant roots make slopes more solid and help prevent erosion, adding pumice to soil enhances and increases vegetative cover. It is frequently used to preserve grass cover and flatness that can deteriorate as a result of heavy traffic and compaction on roadsides, in ditches, and on golf courses. Pumice’s chemical qualities are pH neutral, meaning it is neither acidic nor alkaline. [33] In 2011, horticulture uses accounted for 16% of the pumice mined in the United States. [16]
In regions where pumice naturally occurs in the soil as a result of volcanic activity, it helps to improve soil fertility. For instance, the Ancestral Puebloans of New Mexico’s Jemez Mountains chose to reside on “pumice patches” of the El Cajete Pumice, which probably kept more moisture and was perfect for farming. [34]
Is pumice better than perlite?
When a plant is tall, it is recommended to use pumice since its weight may assist keep the pot from toppling over. Pumice also has a far longer shelf life than perlite. Contrarily, pumice might be harder to find in stores, especially in the crushed form that is typically used in gardening, and more significantly, it might cost more than perlite.
Can I substitute pumice for perlite for growing plants?
Pumice can be used in place of perlite, yes. Pumice is a great medium for plant growth and has several advantages. By improving soil absorption in sandy soils, which reduces runoff and fertilization, it lessens water runoff and fertilization. Additionally, it absorbs extra moisture, which prevents the roots from decaying. Pumice helps to maintain soil structure because it does not disintegrate or compress over time in the same way that other soil additives do.
What can be substituted for perlite?
Depending on the application and the properties of the material, there may be several perlite substitutes. For instance, calcined clay and coarse sand can be used as perlite’s substitutes for aeration. Compared to perlite, sand and clay are less expensive and offer greater drainage. Additionally, as an alternative to perlite, you can use bark, coco coir, peat moss, rice husks, vermiculite, calcined clay, and granite gravel, depending on the needs of your garden.
