Many species of turtles can eat grass. Grass provides fiber and nutrients beneficial to their diet, especially for herbivorous and omnivorous turtles. However, ensuring the grass is free of pesticides and chemicals is essential.

Read on to learn more about the effects of grass on turtles and whether or not they can consume it.

Grass is not suitable for all turtles

Yes, turtles can eat grass, but whether they should depends on the species of the turtle. Here’s a detailed explanation:

Species-Specific Diets

Different species of turtles have different dietary needs. Generally, turtles can be classified into three categories based on their diet: herbivores, omnivores, and carnivores.

Herbivorous Turtles: These turtles primarily eat plant matter. Examples include some tortoise species like the Sulcata tortoise and the Galapagos tortoise. For these turtles, grass can be a significant part of their diet.

Omnivorous Turtles: These turtles eat both plant and animal matter. Examples include the Red-Eared Slider and the Eastern Box Turtle. While grass can be part of their diet, it should be balanced with other food items like vegetables, fruits, and protein sources.

Carnivorous Turtles: These turtles primarily eat animal matter. Examples include snapping turtles. Grass is generally not a significant part of their diet.

Nutritional Content of Grass

Grass is high in fiber but low in many other nutrients. While its fiber content can aid digestion, it lacks many vitamins and minerals that turtles need. Herbivorous and some omnivorous turtles can benefit from grass as part of a varied diet, but it shouldn’t be the sole food source.

Types of Grass

Safe Grass Types:

Timothy hay, Bermuda grass, and orchard grass are generally safe for turtles to consume. These types of grass can be a good source of fiber and help with their digestion.

Potentially Harmful Grass Types:

Grass that has been treated with pesticides, herbicides, or fertilizers can be harmful or even fatal to turtles. It’s crucial to ensure that any grass fed to turtles is free from chemicals.

Grass For Wild vs. Captive turtles

Wild Turtles:

In the wild, herbivorous and omnivorous turtles naturally graze on grass and other vegetation. This allows them to eat a wide variety of plants, which helps them maintain a balanced diet.

Captive Turtles:

Providing pet turtles with a balanced diet that mimics their natural diet is essential. While grass can be included, it should be supplemented with a variety of other vegetables, fruits (in moderation), and protein sources (for omnivores).

Benefits and Risks of feed grass to turtles


Grass provides fiber, which can help with digestion. It also offers enrichment as turtles forage, which can be beneficial for their mental and physical health.


Overreliance on grass can lead to nutritional deficiencies. Additionally, grass from lawns that may have been treated with chemicals can be dangerous.

Does A Turtle Need Grass?

Whether a turtle needs grass depends on the species and its natural habitat.

Many tortoises and some land turtles, such as the Sulcata and Galapagos tortoises, naturally graze on grass and other vegetation in their wild habitats. For these species, grass is an essential part of their diet, providing necessary fiber and aiding in digestion.

While they don’t strictly need grass if other suitable vegetation is provided, grass is a natural and beneficial part of their diet.

On the other hand, species like the Red-Eared Slider and the Eastern Box Turtle eat both plant and animal matter. While grass can be included in their diet, it is not strictly necessary. They require a variety of foods, including leafy greens, vegetables, fruits, and proteins.

Lastly, grass is not a dietary requirement for turtles like snapping turtles, which primarily eat animal matter. These turtles need protein sources such as insects, fish, and small animals.

What Kind Of Grass Is The Best For Turtle?

Timothy hay, Bermuda grass, orchard grass, and fescue grass are among the best types of grass for turtles. They provide essential fiber and aid in digestion. Alfalfa can be included in moderation.

Always ensure the grass is chemical-free and part of a balanced diet to support your turtle’s overall health.

The best types of grass for turtles, particularly for herbivorous and some omnivorous species, are safe, nutritious, and chemical-free. Here are some of the best options:

Grass TypeDescriptionBenefitsNotes
Timothy HayA type of grass hay commonly used as feedHigh in fiber, aids in digestion, low in protein and calciumSuitable for herbivorous turtles
Bermuda GrassWarm-season perennial grass used in pastures/lawnsGood fiber content, nutritious, mimics natural grazingReadily accepted by many herbivorous turtles
Orchard GrassPalatable and nutritious grass hayHigh in fiber, provides good roughageGreat for adding variety to the diet
Fescue GrassCool-season grass used for lawns/pasturesHigh in fiber, beneficial for digestionEnsure it is chemical-free
AlfalfaHigh in fiber, it provides good roughageHigh in protein and calcium, beneficial for young turtlesShould be fed in moderation due to high calcium content

Do All Turtles Eat Grass?

Not all turtles eat grass. The dietary habits of turtles vary widely depending on their species and natural habitat.

Turtle TypeDiet Includes GrassDescriptionExamples
HerbivorousYesPrimarily eat plant matter, including grassSulcata Tortoise, Galapagos Tortoise
OmnivorousOccasionallyEat both plant and animal matter; grass can be includedRed-Eared Slider, Eastern Box Turtle
CarnivorousNoPrimarily eat animal matter; grass is not a part of their dietSnapping Turtle, Softshell Turtle

Do Snapping Turtles Eat Grass?

Snapping turtles are primarily carnivorous and do not typically eat grass as a significant part of their diet. These turtles mainly consume animal matter, including fish, amphibians, insects, small mammals, birds, and carrion.

Their carnivorous nature is driven by their need for high protein intake, which supports their growth and energy requirements.

Grass and other terrestrial plants do not provide the necessary nutrients, particularly protein, that snapping turtles need to thrive.

While snapping turtles are predominantly meat-eaters, they do occasionally consume some plant matter.

This is usually incidental and involves aquatic plants and algae rather than terrestrial plants like grass. Plant material is often ingested accidentally while turtles hunt for animal prey in their aquatic habitats.

The presence of plant matter in their diet is minimal and does not significantly affect their overall nutrition.

Do Painted Turtles Eat Grass?

Painted turtles are omnivorous and have a varied diet that includes both animal and plant matter.

While they do not primarily eat grass, they may occasionally consume it as part of their diet, especially when other preferred food sources are not readily available.

In their natural habitat, painted turtles feed on a variety of foods. They eat aquatic plants, algae, small fish, insects, crustaceans, and carrion.

Younger painted turtles tend to be more carnivorous, focusing on protein-rich foods like insects and small aquatic animals to support their growth.

As they mature, they gradually incorporate more plant matter into their diet, becoming more herbivorous as adults.

Do Box Turtles Eat Grass?

Box turtles are omnivorous and have a varied diet that includes both animal and plant matter. While they can eat grass, it is not a significant part of their diet. Instead, box turtles prefer a variety of other foods that provide the nutrients they need.

In the wild, box turtles eat a wide range of foods depending on their environment. Their diet includes insects, worms, snails, and other small invertebrates, which provide essential protein.

They also consume various fruits, vegetables, fungi, and leafy greens. While box turtles might nibble on grass occasionally, they typically favor softer, more nutritious plant materials over tough grasses.

Do Sea Turtles Eat Seagrass?

Yes, sea turtles do eat seagrass, and it is an important part of the diet for some species, particularly green sea turtles.

Green sea turtles are primarily herbivorous, especially as adults, and seagrass forms a significant portion of their diet. Young green sea turtles are more omnivorous, consuming a mix of plant and animal matter, but as they mature, they shift towards a more plant-based diet.

Can Baby Turtles Eat Grass?

Baby turtles’ ability to eat grass depends on their species and specific dietary needs.

For herbivorous species, such as the Sulcata tortoise, baby turtles can consume grass as part of their diet.

However, it’s important to include a variety of other greens and vegetables to ensure balanced nutrition. Tender, easily digestible plant matter is particularly suitable for baby herbivorous turtles, so softer grasses and finely chopped leafy greens are recommended.

In the case of omnivorous species like the Red-Eared Slider and the Eastern Box Turtle, baby turtles primarily require a higher protein diet to support their rapid growth and development.

They typically feed on insects, worms, and other small animal matter. While they might nibble on grass occasionally, it should not be a primary food source.

As they grow older, their diet can gradually include more plant matter, including grass, but initially, animal protein is more critical for their development.

For carnivorous species such as the Snapping Turtle, baby turtles predominantly consume animal matter. Their diet consists mainly of small fish, insects, and other protein-rich foods.

Grass is not a suitable or necessary part of their diet at any stage, particularly during their juvenile phase when their need for protein is highest.


If you’re going to have a turtle as a companion, you should research its natural environment and the food it would eat if you weren’t providing for it.

If we want them to survive, we need to feed them a diet that is as close as possible to their natural diet.

Also, if you take your turtle outside and find it grazing on the grass, don’t panic. It’s only enjoying its natural environment.
