This will be just as important for many land turtle species as the indoor enclosure. Make sure yours is large and safe. Turtles need to be protected from predators and from escape. Your enclosure should be tall enough they cannot escape over it, and have barriers under the dirt so they can’t burrow under. A roof for the enclosure is also typically a necessity. Do not just use the dirt you have in your backyard -- it’s not appropriate for land turtles. Be advised that grass, particularly wet grass, is also bad for land turtles. It can cause painful abrasions. Since your turtle will be spending a lot of time outdoors, planting food for them makes a lot of sense. You won’t have to look for food for them, and they can choose to eat when they want to. Don’t just have a flat and boring outdoor enclosure. Create little hills they can climb, different areas to explore, and a variety of environments within the enclosure.

TL;DR in Vietnamese:
Làm nơi ở ngoài trời cho rùa. Đảm bảo sử dụng đất nền để làm nền cho nơi ở của rùa. Cung cấp các loài thực vật mà rùa thích ăn. Tạo nơi ẩn náu và khám phá cho rùa bằng các vật liệu như đá, gỗ, v.v….
