Answer:

A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place". Weed species are either broadleaf or grassy type. A few examples of broadleaf weeds are clover, dandelion, and purslane.

Weeds reduce farm and forest productivity, they invade crops, smother pastures and in some cases can harm livestock. They aggressively compete for water, nutrients and sunlight, resulting in reduced crop yield and poor crop quality.

The two mechanical control techniques most often used are tillage and mowing. Fill one with undiluted white vinegar to get rid of the weeds and grass poking out of the cracks in your concrete, as well as ants and other insects—but be careful not to spray it on your plants; the high acidity could kill them.
