Re-Fertilizer

Re-Fertilizer is a craftable material in ARK: Survival Evolved. It can re-grow plants, trees, and even rocks that have been harvested previously.

Usage
To use it, place it into your hotbar and then use the item in the requested area, or use when activated in your inventory.

The area of effect is quite small, it is not much more than a single foundation. And it has a period of non-working (If you cut down the tree it will not grow immediately even if you use Re-Fertilizer. You need to wait some time before it will work)

Re-Fertilizer currently doesn't seem to work in Single Player. (tested 1/20//2020)
