As of Alpha 16, Gardeners are now not workers and will plant trees. Gardeners are important as they keep environments clean of vines which in turn keeps the prisoners happier.
Gardeners are also key in your "forestry" development, as they will automatically buy and plant trees in this zone. The trees grown there will be cut down and distributed by Workmen.
The Gardener requires a Foreman before hiring is possible. Research will cost $2,000.
- The behavior of the gardener as of now isn't very optimal. It is best to hire a lot to have optimal outdoor looks.
