Savroot & Seeds
Farmable Crops - Ark: Survival Evolved
Savroot is considered an advanced crop in Ark. Its seeds are found in the wild like most other seeds, but the only way you can get actual Savroot is by growing it in a medium or large crop plot.
To get yourself seeds, simply harvest the various bushes either by hand or with a Dino. The seeds are not that uncommon. They can be used as a food source, in addition to being a required ingredient in some of the Rockwell Recipes.
Farming Savroot
Savroot can be grown in any medium or large sized crop plot and will occasionally produce a seed. Keep in mind that crop plots require water and a form of fertilizer or nothing will grow and the seed will be eventually lost.
