Weedkiller is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, whenever the player manually cuts a Weed, a random adjacent Weed will also be cut. If there is no Weed directly adjacent to the Weed being cut, Weedkiller will have no effect. When cutting a Weed with Weedkiller , the additional Weed will not give extra progress towards being Energized. Weedkiller does not apply to Chickens or Turkeys, they will still only destroy a single Weed at a time. Similarly, this Item does not pose any benefits to the Wacker Tractor. Any Flowers will benefit from this Item exactly as an ordinary Weed would.
Weedkiller effectively allows the player to cut Weeds twice as fast as normal. It has similar Weed-cutting capabilities to Weed Wacker. However, Weed Wacker lets the player become energized in half the time and be more precise when deciding what Weeds to cut. Weeds can also be cut much more quickly and passively with Crampons, so it is unadvised to pick up Weedkiller if the player already has it. While the Wacker Tractor is capable of cutting more Weeds in a shorter time-span, its cooldown time greatly limits its efficiency. Due to this, the player may desire to take this Item even if they already have the Wacker Tractor. In addition, if the player has already acquired several means to generate Flowers then this Item may be of minimal value, simply because of how Flowers can be collected by walking into them or with the Harvest Circle as well.
