this key to identify your weed species
This key includes the most common weeds found in California
lawns. Other species may occur but are not of major importance in
turf. Because flowering parts are often mowed and not seen in turf,
this key was developed using vegetative characteristics. Identifying
weed species is essential for choosing appropriate management practices.
