Beer can do more than quench your thirst after a day working in the garden.
Stale beer left after a party shouldn’t be poured down the drain. Instead use it to fertilize the garden. Be cautious to use beer without preservatives.
Another use for beer, preferably some cheap brand not your best home brew, is to control slugs. Place a shallow dish at ground level and fill about three quarter full of beer. The smell of the beer attracts the pests and they die happy.
Beer can also efficiently clean your metal garden tools. Just pour beer on, leave it awhile and wipe it off. Because of its acidity it cleans and shines the metal surface.
