Identifying Clues Identifying Weed Species

To control weeds, you first need to identify the various types of weeds growing in your turf.  Weeds are either narrow-leaved and grass-like, or broad-leaved.  You also need to know the life cycles of these weeds so you can effectively time your control measures. 
Annual weeds are the most common, living for one growing season and reproducing only from seed. Annuals are controlled by disrupting their growth any time before they set seed.  Perennial weeds do not die after flowering, and many reproduce both by seed and by vegetative means.   Read more »

insecticidal-soap Some Least-Toxic Herbicides

Herbicidal Soap is made from potassium salts of fatty acids derived from naturally occurring plant oils and animal fats.  Contact with herbicidal soap damages plant cell walls, causing dehydration and tissue death.  Soaps are broad-spectrum, non-selective, and work best on seedlings.  Deep-rooted weeds and perennials will require repeat applications.  Soaps break down completely within 48 hours and carry the EPA rating: IV. CAUTION.  There is also an herbicidal soap for use specifically on lawn moss. Read more »
 
 

Herbicides Herbicides

When looking at large areas of lawn contaminated by weeds, most people consider resorting to herbicides.  In fact, it is difficult to go to a local garden supply store without seeing shelves of products all promising to rid your lawn of weed problems quickly.  Unfortunately, herbicides toxic to your weeds are often hazardous to you and other living things.  Certain components of herbicides (i.e. 2,4-D and arsenic) are under scrutiny to determine if they pose serious health hazards.  Many herbicides do not break down quickly but remain active in the soil, increasing both health and contamination risks.  Read more »
