I am looking for good vegetables to feed my Russian Tortoise. I have the Tortoise Table app but most of the safe foods have issues. I currently feed my tortoise Romaine Lettuce and Dandelion Greens (With Sprinkled Calcium and Vitamins). I want to give him a more larger diet. The foods I found that are best are flowers (which I don’t have access too). I am looking for vegetables that can be purchased at supermarkets, High in Calcium and Vitamins, and can be part of my already diet I have set up for him.
