Facts about different types of weeds and how and why you need to control them.
Any plant that is unwanted, out of place, or just has no discernable value can be considered a weed. Approximately 3% (8,000 of 250,000) of plant species found worldwide are classified as weeds.
Weeds are typically grouped into 2 categories based on their plant structure:
Weeds are also classified by their life cycle. Just like flowers and other desirable plants, they can be annual, biennial or perennial.

Weeds deprive desirable plants of needed water, light and soil nutrients. Often unsightly, they can also scratch and irritate skin, aggravate allergies and even harbor insects and disease.
Weeds are simply nature’s way of quickly covering up bare ground. 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 there. While most weed seeds only exist in the soil a few years, there is a small percentage that can remain dormant for decades, waiting for the right growing conditions to occur.
Most plants only produce several hundred seeds, but weeds are especially prolific. One single weed can produce anywhere from 10,000 to over 100,000 seeds. With these odds, it’s easy to see how weeds can quickly take over your garden or lawn if left untreated.
