Can Bearded Dragons Eat Greene

Bearded dragons are charismatic reptiles that captivate with their distinctive features and behaviors. A crucial aspect of their care involves their diet, particularly whether they can consume greens. Indeed, greens are an essential component of a bearded dragon’s diet, providing necessary nutrients that are vital for their health.

Leafy greens such as collard, mustard, and turnip greens should be regular staples. These greens offer a rich supply of vitamins A, C, and K and crucial minerals like calcium, which are indispensable for preventing metabolic bone disease. However, balance is key. In an adult bearded dragon’s diet, greens should represent about 20-25% of their food intake, with the rest comprising a mix of other vegetables, fruits, and insects.

For juvenile dragons, the emphasis is on protein to support their growth, but greens still play a significant role. Owners should aim for a dietary calcium-to-phosphorus ratio of around 2:1 to ensure optimal health.

Incorporating greens into your bearded dragon’s diet isn’t just a matter of nutrition; it’s a step towards mimicking their natural habitat, contributing to their overall well-being. Choose greens wisely, and your bearded dragon will enjoy a robust and healthful life.

How You Can Prepare Greene for Feeding?

Preparing greens for your bearded dragon is a simple process that is vital for ensuring they receive maximum nutritional benefits from their meals. Here’s how you can prepare greens for feeding:

Selection of Greens

Choose fresh, high-quality greens. Organic options are ideal as they are less likely to contain pesticides.


Rinse the greens thoroughly under cool running water to remove any dirt, chemicals, or potential insects.


Cut the greens into bite-sized pieces. The size should be appropriate for your bearded dragon to easily consume—no larger than the space between their eyes to prevent choking.


Prepare a salad mix by combining different types of recommended greens to provide a variety of nutrients. This also keeps mealtime interesting for your pet.


After washing and before chopping, you can gently pat the greens dry with a paper towel to remove excess water, preventing the habitat from becoming too damp.


If recommended by your vet, dust the greens with a calcium or vitamin supplement to ensure your bearded dragon gets its required dietary supplements. This is usually done right before feeding to prevent the powder from being absorbed by the moisture in the greens.


Place the greens in a shallow dish that your bearded dragon can easily access. The dish should be heavy enough to prevent tipping over.

Frequency and Portion Size

Offer greens as part of the daily diet for adults and multiple times a day for juveniles, as they require more frequent feedings. The portion size should be in line with your bearded dragon’s size and nutritional needs.

Removing Uneaten Greens

After feeding time, typically 30 minutes to an hour, remove any uneaten greens to prevent them from spoiling and attracting pests.


Monitor your bearded dragon’s eating habits. Some may prefer certain greens over others, and it’s important to notice what they like and any changes in their eating behavior.

How Too Much Greene Can Harm Your Bearded Dragon's Health?

Feeding too much of certain types of greens can indeed harm your bearded dragon’s health. While greens are an essential part of their diet, it is crucial to offer a balanced variety. Here are some ways in which an imbalance caused by too much of certain greens can lead to health issues:

Oxalate Content

Greens like spinach and beet tops are high in oxalates, which bind to calcium and other crucial minerals, preventing their absorption. Over time, a diet high in these greens can lead to calcium deficiencies, resulting in metabolic bone disease.


Some greens, such as kale and cabbage, contain goitrogens, which can interfere with thyroid function if fed in large quantities over time. This can lead to goiter and other metabolic issues.

Digestive Problems

Greens high in fiber are good for digestion in moderate amounts, but too much fiber can lead to digestive issues, including diarrhea, which can result in dehydration and nutrient loss.

Nutrient Imbalance

Focusing too much on certain greens can lead to an imbalance in vitamins and minerals. For instance, too much vitamin A (found in carrots and sweet potatoes) can lead to vitamin A toxicity, while not enough can cause deficiencies.

Picky Eating

Overfeeding a particular type of green can lead to picky eating habits, where the bearded dragon may refuse to eat other necessary foods, leading to an imbalanced diet.

Hydration Issues

Although greens contain water and can aid in hydration, too much moisture from greens can also cause diarrhea, which in turn can lead to dehydration if not balanced with proper water intake

Greene That Should Be Avoid In Bearded Dragons Diet

Certain greens and plants should be avoided in a bearded dragon’s diet due to their potential harmful effects. Here are some greens and other plants that are generally recommended to be excluded:

Rhubarb: Contains oxalic acid, which is toxic to bearded dragons and can lead to kidney failure.

Avocado: The leaves and fruit contain persin, which is toxic to many animals, including bearded dragons.

Onions and Garlic: These can cause blood abnormalities and digestive issues.

Spinach: While not toxic, spinach contains high levels of oxalates, which can bind to calcium and inhibit its absorption, potentially leading to metabolic bone disease if fed regularly.

Lettuce: Particularly iceberg lettuce, which is very low in nutrients and high in water content, providing little nutritional value and potentially causing diarrhea.

Wild plants: Unless you are certain that a wild plant is safe and not treated with pesticides or herbicides, it’s best to avoid feeding it to your bearded dragon.

Tomato leaves and stems: The leaves and stems of tomato plants are toxic, although the fruit is safe in moderation.

Citrus fruits: While not a green, citrus fruits like oranges and lemons are often mistakenly considered potential vitamin C sources. They are too acidic for bearded dragons and can upset their stomach.

Beet Tops: The leaves of beets are high in oxalates, similar to spinach.

Beans: Raw beans can be harmful due to substances that can interfere with vitamin absorption and digestion.

Mushrooms: Not a plant but often grouped with vegetables, mushrooms can be difficult to digest, and some varieties can be toxic.

The Bottom Line

A well-balanced diet rich in appropriate greens is crucial for the health and longevity of bearded dragons. While greens such as collard, mustard, and turnip greens, along with dandelion and arugula, provide essential nutrients like vitamins A, C, and K, and minerals like calcium, they must be offered in moderation to prevent nutritional imbalances. Certain greens high in oxalates or goitrogens, such as spinach and kale, should be fed sparingly, while others, like rhubarb, avocado, and iceberg lettuce, should be avoided altogether due to their potential toxic effects or lack of nutritional value.
