Please access the above link to view an extensive list of plants that are safe to use in your naturalistic environments. You will also find resources for identifying safe plants for environments and food items.
I strive to educate the public on the level of commitment that reptiles and amphibians require, to keep unwanted pets from being released into our environment, and to provide knowledgeable, responsible homes for unwanted pets. Please visit to learn more.
Nutritional Values of Common Food Items
Here are charts showing some of the nutritional values of commonly fed vegetables, greens, and fruits.
Vegetable Oxalic Acid (g/100g)
Ca:P Ratio- Another very important consideration is the calcium phosphorus ratio, otherwise seen as Ca:P. The proper ratio is to be no less than 2:1. Some experts recommend raising the ratio to 5:1 using proper supplementation, such as pure calcium carbonate. Having a proper ratio in your feed is very important for calcium absorption.
Vegetable Calcium:Phosphorus Ratio
|Beet Greens *||3.0:1|
|Chinese Cabbage (pak-choi)||2.8:1|
|Lettuce, Loose leaf||2.7:1|
|Lettuce, Butterhead (Boston, Bibb)||1.4:1|

I also have a page with an extensive list of known edible plants. Another great site to visit, that contains detailed nutritional information is Nutrient Analysis of Replacement Turtle and Tortoise Foods from the World Chelonian Trust. There is also the Sulcata Station.
I know that all of this information can be very difficult for a new or prospective tortoise owner to take in all at once. Getting a tortoise is a lifetime and very detailed commitment. If at any time I can be of any help, or if you have any questions, please do not hesitate to email me at firstname.lastname@example.org and I will do my best to assist you. The only stupid question is the one that you don't ask, and in the end, compromises the life and health of your tortoise.
