Choosing The Right Substrate For Your Pet Tortoise

There are a number of things you will want to consider when choosing a substrate for your pet tortoise, and it can become overwhelming.

That’s why we’ve covered the main considerations below! We’ve pulled together all the information you need to make an informed decision.

Types of Substrate

A substrate is used as bedding to line your tortoise’s enclosure.

The best substrates retain moisture, reduce bad odor, and will be easy to use and work with from an owner’s perspective.

The better substrates can hold more moisture, ensure sufficient humidity, are soft and comfortable and are also economical and cost-effective.

It’s important to note that not all types of substrate marketed for reptiles are either safe, practical, or ideal for pet tortoises.

Perhaps the most common are Sand, Newspaper, and Hay.

These can be ingested, causing digestive issues and complications that can arise from impaction.

Certain wooden chip shavings can also contain harmful and toxic compounds which can harm your tortoise. Cedar and pine are the most common two to be aware of.

So with this in mind, what are the safest and best types of substrate for pet tortoises.

Cypress Mulch

Cypress Mulch is a soft organic material that helps your tortoise to feel comfortable in what appears to be a wild environment.

It has a pleasant fresh ‘woody’ scent that keeps optimal humidity and retains the appropriate level of moisture.

This is because it regulates the temperature of your tortoise’s enclosure; keeping it warmer in colder environments and cooler in hotter climates.

If you like or want to introduce plants to your tortoise’s enclosure, cypress mulch is an excellent choice and will make this possible.

A lot of tortoise owners actively use cypress mulch, with Zoo Med Forest Floor Bedding from Amazon being a household name and brand.

Coconut Fiber

Coconut fiber is one of the most popular types of substrates used by reptile owners, including tortoises. It is all-natural, soft, and comfortable bedding for your pet.

Coconut fiber also does a good job at removing odors; ensuring your tortoise’s environment is clean and hygienic. It does this by breaking down any waste and excrement produced by your pet.

It is also very easy to swap out because the soiled substrate is easy to observe and identify.

This makes cleaning effortless and is far more economical as you do not need to replace all of the substrates at a time.

Coconut-fiber substrate will retain optimal humidity within the enclosure, but you can also keep it dry if required.

ReptiChip Premium Coconut Fiber Substrate from Amazon is a popular and well-reviewed brand in this category.


Moss is another all-natural compound that is a popular substrate for baby tortoises. This is a small flowerless green plant that is dense and damp – that occurs and grows in shady locations.

Moss is highly absorbent and can contain large amounts of water at any one time. Its most suitable for warm and humid enclosures, and for hatchling to burrow into.

Additionally, slightly soiled moss can be washed in boiling water and reused – making it very economical and versatile.

Moss can be quite messy, and owners need to ensure that their tortoises are not consuming too much of it accidentally as it tends to stick to food and other items.

When looking for a Moss, you need to ensure that it is all-natural and grown in specific environments. This is partly why the Exo Terra Forest Plume Moss from Amazon is so popular.

It is sourced from Asia and does not contain any harmful additives or compounds.

Laying Substrate

As discussed earlier in this buyer’s guide, the substrate is used to line the enclosure for your tortoise. It is what they will live, sleep and walk upon.

When you lay the substrate, you should follow the manufacturer’s instructions of how much to use and how to get the most out of their product.

This is usually contained on the side of the packaging – but contacting the manufacturer directly is a good alternative if this information is not available.

Generally, you will need to lay sufficient substrate to cover the base of your tortoise’s enclosure.

If you are working with just one substrate then this should suffice. However, if you want to use a combination of substrates, i.e. Coconut Fiber and Moss you’ll need to ensure you lay them down appropriately.

In this example, the Coconut Fiber-based substrate would be laid down first, and the moss on top.

You need to change the substrate often; especially soiled substrate. This will ensure your tortoise remains safe and healthy and prevents dangerous bacteria and germs from collecting and building up.

The best substrates will allow you to identify excrement. This will make cleaning a lot easier and it will also prove to be a lot more economical and cost-effective.

Keeping Your Tortoises Enclosure Clean and Hygienic

Your tortoise’s enclosure must remain as clean as possible. This will ensure that they do not suffer from any illnesses brought about by bacteria that are able to build in the enclosure.

Remember, bacteria and germs can grow very easily in a tortoise enclosure because it is kept moist and humid.

When it comes to cleaning your tortoise’s enclosure, you should be looking to conduct a light daily clean with a thorough deep clean every month.

Daily Enclosure Cleaning

Daily enclosure cleaning should consist of removing the soiled substrate. You should also look to clean the water bowl during this time.

Monthly Enclosure Cleaning

Once per month, you should be looking to conduct a deep clean.

To do so, you will need to remove and dispose of all of the substrates. From there, you will need to disinfect the enclosure and all accessories inside (hides, heat lamps, etc.)

When doing so, you should look to use particular products intended for cleaning reptile enclosures that are completely removed before your tortoise is returned.

Related Questions

How Much Substrate Should A Tortoise Have?

A tortoise requires sufficient substrate. At a minimum, it should be 50mm/2 inches in depth at any one time. Of course, how much substrate you will need to use will depend on the substrate type and material it is made up of.

How Often Should You Change Tortoise Substrate?

Soiled substrate should be removed and replaced daily. Whereas, the remaining substrate should be removed once per month during a thorough and deep clean of the enclosure. How long a particular substrate will last ultimately depends on the type of substrate used and the quality of the materials/ brand.
