*greens-
collard, kale, turnip, mustard, romain, bok choi(i think its spelled that way), rose petals(not from public places, if possible grow your own.), dandelions(same as roses), there are a few others but I cant think right now
*fruits-
Strawberries, rasberries, blueberries, banana, ground up apple chunks, most fruit flavored babyfood(dont rely on this as a staple diet only use as a treat, it can cause loose stools and ultimatley dehydration.Its also a good thing to use when treating your dragons or bulking them up for the breeding season before cooloff.)I have noticed that some dragons will eat a little of citrus fruits such as oranges, mango, etc etc. But it really depends on the individual animal.
*insects
*My favorite part of a beardies diet, and should be its staple diet aside from greens and fruits.
Any cockroaches, crickets, superworms, grubs, grasshoppers, praying mantids, silkworms, superworm beetles, and basically any other farm raised insect that moves.
*All bearded dragons should be fed prey items according to the width of their head to ensure the animal wont swallow something too big and paralyze itself.
**Also supplementing with Calcium and vitamins shoudl be a daily routine for the beardie keeper.
