Abstract

One of the most persistant weeds found in New Mexico lawns is the common dandelion (Taraxacum officinale Weber). In Albuquerque, where this study was made, most lawns are of Kentucky bluegrass (Poa pratensis L.), a poor competitor against the inroads of the dandelion. However, some lawns are of Bermuda grass (Cynodon dactylon pers.), which, with its thick and vigorous turf, is a better competitor with the dandelion. The writer has observed, as Dittmer also found, that the turf of Bermuda grass on the campus of the University of New Mexico will crowd out or prevent the entrance of dandelions, while a bluegrass lawn, even when vigorous, is less resistant and after a period of several years, the dandelion becomes well established in it. Where a continuous greensward is desired, the profusion of yellow flowers, coupled with the disappearance of the grass due to the competition, causes the dandelion to be looked upon as a weed, with its long, naked peduncles contributing to the ragged and unkempt appearance of the lawn.
