A Scarecrow in ArcheAge
Design: Scarecrow Garden is a reward earned from one of the very early Blue Salt Brotherhood farming quests. Once you have obtained the Design: Scarecrow Garden you can then place it, along with 10xlumber in order to control your own 8x8 area of land for growing plants or livestock.
Your Design: Scarecrow Garden is also used as a component to create a Farmer's Workstation. If you sell or otherwise trade your Design: Scarecrow Garden there is no way to obtain a new one aside from creating a new character.
