Celery Health Concerns
Overall celery does not have any major nutrition concerns. Keep in mind celery is mostly water with few nutrients, but the nutrients it does contain are fairly well balanced which makes it a good choice for hydrating your beardie.
Celery does contain oxalates (as do most plants), but the oxalic acid level is not high enough to cause any major concerns. Feeding your bearded dragon one stalk per day would be fine as long as it was prepared correctly.
