Weeds are plants, and they function just like the desirable plants in your yard. They need water, sunlight, and nutrition to survive. They are opportunistic and aggressive, they are genetically designed to germinate, grow and propagate faster than most desirable plants. Weed seeds are especially adapted to spread. They are widely distributed by animals, insects, hay, mulch, and topsoil. Once they find their way to your lawn and garden, they can remain.
