Tarweed is well adapted for survival as a nuisance plant on California ranges. While expensive control measures may not be justified, effective methods are needed for minimizing the use of soil moisture by tarweed seedlings in the spring. Clipping or heavy grazing and nitrogen fertilization offer possibilities for reduction in density of tarweed seedlings in favor of the more desirable forage species.
