Abstract

The effects of clipping California-poppy (Eschscholzia californica Cham.) at various growth stages on plant survival, flowering, herbage yield, and root production were studied at the San Joaquin Experimental Range, in central California. Plants were clipped once to a 2-cm stubble at one of six stages. Through the early reproductive stage, a single clipping had little effect, but clipping at either the start or peak of vernal flowering reduced the display of spring flowers. Other factors studied were not significantly affected.
