Bearded dragons need a balanced diet. As omnivores, they require a mix of both protein from feeder insects and a variety of fruits and vegetables. Depending on the age of your bearded dragon, this mix is a little different. Young dragons need more protein and should be fed mainly insects. Adults should eat more vegetables and fruits. When feeding vegetables and fruits to a bearded dragon, ensure they are chopped into pieces that are smaller than the space between the bearded dragon's eyes.
Squash is a good staple vegetable for a bearded dragon. Choose from acorn squash, butternut, kabocha, yellow, zucchini or spaghetti squash. Peel and discard the seeds and chop the squash into fine pieces.
Mushrooms will add phosphorus to a bearded dragon's diet, and asparagus will provide a high amount of protein, which is a good for young bearded dragons. Chop the aspargus into small pieces or shred with a fork.
Bell peppers are a favourite among many bearded dragons. Mix small pieces into the dragon's other food if they are not eating well. The strong taste and colour may entice them to eat.
Sweet potatoes are another enticing food for bearded dragons. Chop these very small and mix into other greens and fruits for a boost of nutrition.
Bearded dragons require a lot of calcium in their diet for bone development and to avoid any problems with metabolic bone disease. Chicory, collard, mustard, watercress, turnip greens, spinach, kale and dandelion greens are vegetables containing high levels of calcium. Cut, chop or shred the greens into small pieces. Prepare them ahead of time by storing the dried pieces wrapped in paper towels and placing them in a plastic bag in the refrigerator.
Iceberg lettuce should not be fed to a bearded dragon because it contains very little nutrients or taste. Romaine lettuce should also be avoided, as it can cause a bearded dragon to have runny, smelly poop.
Prickly pear, mango and papaya are all good fruit choices for a beard dragon. Remove the seeds or pit, and chop the fruit into fine pieces to mix with the greens and other vegetables.
Tomatoes make for a good treat because they are a great colour enhancer and have a high water content like melons such as honeydew, cantaloupe and watermelon.
Raspberries can be fed whole to full-grown adult bearded dragons; otherwise, you should crush and add them to their greens for a flavourful boost of fibre.
Grapes, kiwi and peaches should always be chopped before feeding them to a bearded dragon. Fruits should make up the smallest portion of a healthy bearded dragon's daily diet—significantly less than the amount of greens or insects.
Avoid giving a bearded dragon citrus fruits such as oranges, grapefruits, lemons and limes.
