Can you use regular potting soil for succulents?

Only if you cut it heavily with coarse mineral material. Standard potting soil is built around peat or coco coir and is designed to hold water for weeks, which is the opposite of what a succulent root system tolerates. Used straight, it stays wet long enough for root rot to take hold, and the symptoms — soft translucent lower leaves, a mushy stem at soil level — appear well after the damage is done. Mixing it half and half with pumice or perlite makes it usable.

Is bagged cactus mix good enough?

It is a reasonable starting point and usually still too water-retentive on its own. Most bagged cactus and succulent mixes are ordinary potting soil with a modest amount of sand or perlite added, and they behave much closer to potting soil than to a gritty mix. The standard fix among succulent growers is to add an equal volume of pumice or perlite to the bag before potting. That single step converts an adequate mix into a good one for a couple of dollars.

Should you use sand in succulent mix?

Coarse horticultural or builders sand yes, fine sand and play sand no. The distinction matters more than any other ingredient question. Coarse sand has particles large enough to create air gaps between them, which is what improves drainage. Fine sand particles fill the spaces between soil particles instead, and the result compacts into something close to concrete that holds water and excludes air. Never use beach sand, which also carries salt.

Does the pot matter as much as the mix?

Nearly. A drainage hole is not optional — no mix drains through a sealed container, and a succulent in a pot without one is on a countdown. Unglazed terracotta helps further because it is porous and dries the rootball from the sides as well as the top, which is why so many succulent growers use it. Match the pot size to the plant too: a small plant in a large pot sits in a mass of damp mix it cannot dry out.

How often should you repot into fresh mix?

Every two to three years, or sooner if water runs straight through without wetting anything or sits on the surface for minutes. Organic components break down over time, the particles get finer, and the mix that drained well when new gradually turns into something that holds water. Spring is the usual time. Let the plant dry for a few days before repotting, keep it dry for a week afterward, and let any damaged roots callus rather than watering them immediately.

Succulents need a mix that is at least half coarse mineral material. The standard recipe is one part potting soil, one part coarse sand or fine gravel, and one part pumice or perlite — roughly 60 to 70 percent mineral by volume. The purpose is drainage and air: succulent roots evolved in gritty ground that dries within days, and they rot in soil that stays damp for a week. Ordinary potting mix, built around peat or coir to hold moisture, is the single most common cause of dead succulents indoors. Bagged cactus mix helps but is usually still too retentive without added grit.

What is the actual recipe?

Mix by volume, not by weight, and use a bucket rather than trying to judge it in the pot. Any of these work; the first is the everyday version and the last is what serious collectors use.

Mix	Proportions	Drainage	Best for
Everyday succulent mix	1 potting soil : 1 coarse sand : 1 perlite	Good	Echeveria, sedum, haworthia, jade
Pumice version	1 potting soil : 2 pumice	Very good	Most succulents; the easiest to get right
Bagged cactus mix, amended	1 cactus mix : 1 pumice or perlite	Good	Anyone not mixing from scratch
Gritty mix, no soil	1 pumice : 1 calcined clay : 1 crushed granite	Excellent	Cacti, lithops, collectors
Standard potting soil	As sold	Poor	Not succulents

Aim for particle sizes roughly between an eighth and a quarter of an inch. That is the range that creates air pockets. University extension guidance on cactus and succulent culture, including from Utah State and the University of Arizona cooperative extension programs, consistently emphasizes coarse, sharply draining media over any specific ingredient list — the principle matters more than the brand.

What does each ingredient do?

Pumice. The best single amendment. Porous volcanic rock that holds a little moisture and a lot of air, does not float or compact, and lasts indefinitely. If you buy one thing, buy this.
Perlite. Cheaper and widely available, does the same job, but it is light and floats to the surface when watered from above. Perfectly good in a blend.
Coarse sand. Improves drainage only if it is genuinely coarse. Horticultural or builders sand, never play sand or beach sand.
Calcined clay. Sold as turface or as oil-absorbent granules. Holds moisture in its pores while keeping large air gaps between particles.
Crushed granite or poultry grit. Pure drainage and weight, useful for top-heavy plants that tip over.
Potting soil or coir. The nutrient and moisture fraction. Necessary in small proportion; ruinous in large.
Bark fines. Optional, adds structure, breaks down over a couple of years.

What to leave out: peat-heavy mixes sold for seed starting, anything advertising moisture-retaining crystals or a feed-for-six-months formulation, garden soil from outside, and vermiculite, which holds far too much water for this purpose.

Does the mix change how you water?

Yes, and this is where people get caught out. A gritty mix dries quickly, so succulents in it need watering more often than the once-a-month advice suggests — typically every 10 to 21 days in summer and much less in winter. The method is to soak thoroughly until water runs from the drainage hole, then leave it completely alone until the mix is dry all the way through. Frequent small sips keep the top damp and the roots thirsty, which is the worst of both.

Check with a finger two inches down or by the weight of the pot. If you have already overwatered, the recovery steps are in how to save an overwatered plant, and constantly damp mix is also what breeds the pests covered in how to get rid of fungus gnats.
