Can Cactus Grow In Sand? We Have All The Best Tips!

Can cactus grow in sand?

Cacti are commonly found in deserts, but can cactus grow in sand only? Despite their natural occurrence being in a sand-filled area like a desert, cacti need other soil blends to grow.

So if you’re thinking of getting a cactus, it is best to look into the soil and sand mixture options. Just sand itself can be damaging for the plant, so we’ve listed everything you need to know.

The Role of Sand in Cactus Growth

Cactus plants need less amount of water compared to other plants, so it is important that the soil they grow in provides drainage. The porous and pebbly texture of sand makes it a great draining agent, which is beneficial for the cactus.

However, pure sand drains water very quickly. So when a cactus is kept in pure sand with no additional soil mixture, the water will drain from the sand before the plant gets a chance to absorb it. As a result, the cactus’s growth is put at risk.

Can You Root Cactus in the Sand?

You can definitely plant cacti in the sand, as long it has other types of soil mixed with it. You need to include a mixture of soil with pure sand that is preferably inorganic.

That way, the porousness of the sand and the moisture-keeping quality of the different soil will create the best environment for the cactus to grow.

Cactus Soil vs. Coarse Sand

Pure sand, regardless of whether it is coarse or fine, is bad for cacti. Coarse sand will create an abrasive surface for the roots, which can eventually damage the capillaries. For fine sand, the water is retained for longer and does not allow any air to pass by.

Cactus Soil vs. Coarse Sand

Even if you’re using a well-draining pot, the sand will clog the moisture and prevent any sort of ventilation. So the best option is to use a mixture of earth and sand, which is known as cactus soil. Important things about cactus soil are –

  • It is a blend of both organic and inorganic substances, including sand, gravel, pebbles, and perlite
  • Does not retain moisture, thus preventing the cactus roots from rotting and also accumulating moss
  • Provides enough air to pass through the roots
  • Allows the perfect amount of drainage, unlike too much pure sand does; and
  • It is rich in nutrients that assist in healthy cactus growth.

Tips for Growing Cactus in Sand

If you want to grow a healthy cactus in the sand, here are some tips you can follow:

Tips for Growing Cactus in Sand

1. Get the Proper Mix

The ratios of the different materials to be mixed with the sand are very important. If you are not an expert gardener, it is recommended that you buy readymade cactus soil/mix from the market and use that to plant your cactus.

You can also make your own mix based on the type of cactus plant you have. Common proportion includes –

  • 3 parts sand (or gravel or grit)
  • 3 parts potting soil
  • 2 parts pumice or perlite

Mix these thoroughly together in a container first, and then plant your cactus.

2. Do Not Under/Overwater the Sand Mix

Even with the right mix of soil, adding the wrong amount of water can damage your cactus altogether. You might be tempted to keep watering the plant to make it grow faster, but overwatering it will damage its roots eventually.

Cacti might be drought resistant, but that doesn’t mean you should water them too little, either. While watering, make sure that –

  • the soil is dry before each watering session
  • scheduled watering times don’t exceed once or twice each week
  • less than a cup of water is used each time
  • Change the Sand Periodically

Keeping the cactus in the same potting soil/sand will eventually cause the sand to lose its nutrients. Make sure to replace and report the sand mix once every year.         

  • Use a Container with a Hole Underneath

Since sand itself retains water, it is important to create a space for excess water to drain out. For any type of cactus, having a pot with a drainage hole at the bottom is crucial.

How Long Can a Cactus Live in Sand?

When placed in pure fine or coarse sand, the cactus will survive only a few weeks to a month, at maximum. The sand alone is not a good medium to provide the cactus with enough water and nutrients due to its high water retention attribute.

How Long Can a Cactus Live in Sand

For the healthy growth of a cactus, there needs to be a mixture of sand and other soil elements. With the correct ratio of sand and soil mixture, the cactus can live up to 10 years.

Can You Plant a Cactus in Sand?

Planting a cactus in the sand is not impossible, but there are a few things you need to understand:

  • the cactus’s growth will be slower and stunted than usual
  • coarse sand works better than fine sand, as it allows more water drainage
  • there are not enough nutrients in the sand alone
  • risk of too much or too little water absorption is high

If you must use sand for your cactus, then adding some other soil mixtures is mandatory. Otherwise, the cactus will not survive.

There is readymade cactus soil available in the market, which is an option most beginners go for.

We recommend using pre-mixed cactus soil if this is your first time planting a cactus. If you’re an expert gardener, you can also check out some specific fertilizer mixes for your cactus.

Final Words – Can Cactus Grow in Sand?

Pure, unmixed sand is not a good option for growing cacti. They need sufficient water drainage to grow, and pure sand does not allow that because of its texture and composition.

The best thing to do is mix other inorganic and organic soil components with the sand. Also, each cactus species is different, so it is best to do proper research before getting any sort of soil mixture.
