The tortoise diet calendar provides a species-specific weekly feeding guide for the most common pet tortoise species. Select your tortoise's species to see approved staple foods, frequency, supplement schedule, and what to avoid.

How to Use the Tortoise Diet Calendar
Tortoise nutrition is highly species-dependent. Mediterranean tortoises evolved eating high-fiber, low-protein wild plants in semi-arid environments. African Sulcata tortoises evolved as pure grazers on tough dry grasses. Tropical Red-footed tortoises have a more omnivorous diet including some fruit and protein. Feeding inappropriate foods for the species is one of the most common causes of health problems in captive tortoises.
Step 1: Select Your Tortoise's Species
Ensure you know exactly which species you have — common names can be ambiguous. Russian and Greek tortoises look similar but have slightly different care requirements. Sulcata are the largest common pet tortoise and have very different dietary needs from their smaller Mediterranean cousins.
Step 2: Follow the Weekly Calendar
The weekly calendar shows which food categories to offer on which days, ensuring variety within appropriate food groups. For most species, variety within approved greens is the key to nutritional balance. A tortoise eating only one or two greens exclusively is at risk of nutritional imbalances over time.
Step 3: Never Skip Calcium Supplementation
Metabolic bone disease is the most common preventable health problem in captive tortoises and is caused by calcium deficiency or poor calcium-to-phosphorus ratio. Dust food with calcium powder 2–3 times per week and provide a cuttlebone for self-supplementation. Tortoises living primarily indoors need UVB lighting to synthesize vitamin D3 for calcium absorption.
FAQ
What do tortoises eat?
Most Mediterranean tortoises (Russian, Greek, Hermann) eat primarily leafy weeds and grasses: dandelion greens, plantain, clover, and various wildflowers. Tropical species like Sulcata eat mostly grass hay. Red-footed tortoises are omnivores who also eat some fruit and occasional protein. Species-specific diets vary significantly.
How often should I feed my tortoise?
Adult Mediterranean tortoises (Russian, Greek, Hermann) can be fed daily or every other day. Sulcata and Leopard tortoises should have unlimited grass hay available always, with fresh greens 3–5 times per week. Red-footed tortoises benefit from daily greens with fruit 2–3x per week.
What foods are toxic to tortoises?
Avoid all foods from the nightshade family (tomatoes as a staple, peppers), rhubarb (highly toxic), daffodils, azaleas, and rhododendrons. High-oxalate foods like spinach and beet greens should be avoided or strictly limited. Iceberg lettuce has no nutritional value. For all species, avoid processed foods, bread, and dairy.
Should I give tortoises calcium supplements?
Yes. Dust food 2–3 times per week with calcium carbonate powder (plain calcium, no D3) and provide a cuttlebone for tortoises to gnaw on at will. Tortoises that live primarily indoors may also need vitamin D3 supplementation or UVB lighting to metabolize calcium properly.
Can tortoises eat fruit?
Mediterranean species (Russian, Greek, Hermann) should have very limited fruit — the high sugar content disrupts gut flora and can cause loose stools and proliferation of unhealthy bacteria. Tropical species like Red-footed and Yellow-footed tolerate fruit better. Sulcata and Leopard tortoises should have essentially no fruit.
How much should I feed my tortoise at each meal?
A general guideline: feed an amount roughly the size of your tortoise's shell (surface area) at each meal. Most tortoises are grazers and will not overeat greens, though they will overeat high-calorie foods. For Sulcata, unlimited grass hay is appropriate; they evolved as high-fiber grazers.
