Kill Weeds
Even if you aren't growing fruits, vegetables or herbs to eat, you probably don't want to spray pesticides in your garden. Try full-strength (i.e., non-diluted) vinegar on the weeds: its acidity will kill young, pesty plants (though if the weeds are large and threatening to take over, you may need to just yank them out by the roots).
