Grassland tortoise · Sahel, Africa

Know whether your sulcata tortoise's care is actually on track.

Your sulcata can't tell you the basking spot has drifted cool, or that a rich diet is quietly pyramiding its shell. baskr watches the pattern across your logs, temperature, humidity, growth and feeding, and shows you what needs attention before it becomes a problem.

Sulcata Tortoise

Basking too cool

Averaged 31°C vs the 35–40°C a sulcata needs. Check the basking lamp.

Basking spot

35–40°C · 95–104°F

Cool side

24–28°C · 75–82°F

Humidity

40–55%

Ideal ranges for Centrochelys sulcata, the same targets baskr scores your logs against.

Basking and warm figures are surface temperatures at the spot; cool and ambient are air. Measure with a probe or infrared thermometer at the animal's height.

Life stage matters: Hatchlings and juveniles need a humid hide and a damper microclimate than the dry adult setup, low humidity while a sulcata is growing drives shell pyramiding.

Sulcata Tortoise: a few things worth knowing

The third-largest tortoise in the world: adults reach 60–80 cm and 45–90+ kg, bigger than a coffee table and heavier than many dogs.
Serious burrowers, in the wild they dig long tunnels to escape the Sahel heat, and captives will excavate a garden given the chance.
They don't hibernate, they come from hot sub-Saharan grassland, so they need warmth year-round, not a winter cool-down.
A pure grazer, it's built to eat grass and hay all day; fruit and rich foods cause real harm.
A genuine lifetime commitment: they live 50–80+ years and outgrow every indoor setup, an adult needs secure outdoor space and a heated shed.

When is your sulcata tortoise active?

Active by day

Where sulcata tortoises come from

Sahel, sub-Saharan Africa

Wild climate. Hot, dry grassland and scrub of the Sahel; blazing days, cooler nights, and deep burrows dug to escape the heat.

Why the care is what it is. This is why baskr targets a 35 to 40°C basking spot, strong UVB and a dry, high-fibre grass diet, with warmth year-round and no hibernation.

What baskr watches for your sulcata tortoise

Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.

Basking spot

35–40°C (95–104°F) over a solid basking area

A cool basking spot slows digestion and, over time, feeds poor growth.

Cool side & damp

A cool side of 24–28°C with no cold, damp corners

Cold or damp is a respiratory risk for a hot-climate grazer.

Humidity & pyramiding

40–55%, with a humid hide for youngsters

Too dry while growing drives pyramiding (a lumpy shell); stagnant damp risks shell and respiratory issues.

Growth & weight

Steady, smooth growth, not rapid

Fast, lumpy growth from over-feeding or protein is a red flag, graze, don't power-feed.

Diet & fibre

Grass and hay-led, weeds, no fruit or added protein

Rich or fruity foods cause runny droppings and long-term harm, keep it high-fibre.

No hibernation

Active and warm year-round

A sulcata going cold and sluggish isn't brumating, it's too cold, warm it and reassess.

How to set up a sulcata tortoise terrarium

Minimum size
Hatchlings start in a tortoise table, but grow fast. An adult ultimately needs secure outdoor space measured in metres plus a heated, insulated shed or house; no standard indoor enclosure is enough long-term. Think garden project, not vivarium.
Temperatures
Basking 35–40°C (95–104°F), warm ambient days, a cool side of 24–28°C, and no cold or damp. They stay warm year-round and do not hibernate.
Substrate
A deep, dig-friendly soil and sand mix or topsoil that holds a burrow, with hay on top for grazing and cover. Keep it largely dry, with a humid hide for youngsters.
Hides & décor
A large, solid hide or house it can't tip, plus shade; adults will use a heated shed. They dig, so expect burrows and secure any boundaries below ground.
Layout
Big and simple: a basking zone with strong UVB, wide floor to roam and graze, a solid hide, shade and dry footing. Outdoors in warm, dry weather is ideal, with a secure, dig-proof, escape-proof boundary.

Plants for a sulcata tortoise terrarium

Safe to include

  • Grasses and hay (Timothy, orchard, meadow)
  • Dandelion
  • Clover
  • Hibiscus (leaves and flowers)
  • Mulberry leaf

Avoid

  • Fruit and fruiting plants
  • High-protein legumes in excess
  • Pesticide-treated plants
  • Toxic ornamentals (buttercup, foxglove)

A grazing lawn of safe grasses and weeds is the ideal, this is a grass-eating machine, not a salad or fruit tortoise.

What to feed a sulcata tortoise, and what to avoid

Staples

  • Grasses and grass hays (Timothy, orchard, meadow)
  • Edible weeds (dandelion, plantain, clover)

Occasional / treats

  • Leafy greens
  • A little hibiscus or mulberry leaf

Never feed

  • Fruit
  • High-protein foods
  • Dog or cat food
  • Pellets not designed for grazing tortoises

Supplements. Calcium (a cuttlebone to gnaw plus light dusting) and UVB do the heavy lifting; keep protein low.

Good to know. High-fibre, low-protein and grass-led. Over-feeding and rich foods are the classic cause of pyramiding and health problems.

The gear that matters for a sulcata tortoise

The right kind of kit, pick brands you trust.

UVB lighting

A high-output 10–12% T5 HO tube (Ferguson zone 3–4) across the basking zone, replaced every 12 months; real sunlight outdoors is even better.

Basking heat

A basking lamp to reach 35–40°C over a solid spot, on a thermostat.

Thermostat

Controls indoor heat; adults in sheds need a safe, thermostatted heat source.

Thermometer + hygrometer

To track the hot basking zone and keep damp in check.

Heated shed (adults)

The realistic long-term housing: an insulated, heated, secure outbuilding with access to a large, dig-proof pen.

Cuttlebone / calcium

A cuttlebone to gnaw supports shell and beak.

The kind of thing baskr will tell you

Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.

Basking spot has averaged 31°C this week, cool for a sulcata (target 35–40°C). Check the lamp, digestion depends on real heat.

Fruit and rich foods logged several times, these drive runny droppings and pyramiding in a grazer. Shift back to grass and hay.

Nights have dropped cold and activity is down. A sulcata doesn't hibernate, warm it up rather than letting it cool.

Sulcata Tortoise care questions

How big do sulcata tortoises get?+

Very big: 60–80 cm and often 45–90 kg as adults, the third-largest tortoise species. They outgrow any indoor enclosure and need secure outdoor space plus a heated shed, so they're a serious long-term commitment.

Do sulcata tortoises hibernate?+

No. They're from hot sub-Saharan grassland and stay warm and active year-round. A sulcata going cold and sluggish is too cold, not brumating, warm it and reassess.

What do sulcata tortoises eat?+

Grass and hay above all, plus edible weeds like dandelion and clover. Keep it high-fibre and low-protein, and avoid fruit, over-rich diets cause pyramiding and health problems.

Can you keep a sulcata indoors?+

Only while small. They grow fast, and an adult needs a large, secure, dig-proof outdoor area with a heated shed. If you can't provide that space for 50+ years, it's the wrong tortoise.
