Weeds Weeds are plants that harm our crops, spring up in our garden, and grow just about anywhere or where people don't want them to. Weeds usally live 1 year or less. Many weeds are destructive.
Weeds spread their seeds in many different ways.
Some weeds, such as the Dandelion, wait for the wind to come around and let their seeds blow around. Birds and other animals spread the weeds seeds, too. Sometimes weeds seeds cling on to your clothing and hitch-hike to a new location.
