Those are fine. Generally speaking I like to use the calcium twice a week and the vitamins once a week. I just sprinkle a tiny pinch on top of the food. You don't need a lot.
Ok thanks! We need to find a way to plant more dandelion because we don't have many in our yard, and our yard is pretty small anyway. I've been taking them from my parents house too, but same thing there.You are using WAYYY too much. A tiny little pinch is all you need.
I don't know about raspberry bushes or sage as tortoise food, but if you found them on a list somewhere, they are probably okay. I've never tried to feed those. Dandelion are much more appetizing. Keep trying with that one and find a few more that are more tasty like grape leaves, mulberry leaves, mallow, sowthislte, etc...
Any new food will take time for them to get used to. Start by finely chopping a very small amount of the new food and mixing it in with an old favorite. Gradually add more of the new stuff over time.
