چکیده
Three palm species common to southern California landscapes were grown and established under mulch treatments. Turfgrass clippings and Eucalyptus sideroxylon mulches increased the growth of king and queen palms and increased survival of king palms. Although palms growing under fresh eucalyptus mulches did not display nutrient de®ciency symptoms, Mexican fan palm and queen palm were not signi®cantly bene®ted by mulch treatments. Mexican fan palm was not adversely affected by turfgrass growing around it. However, turfgrass signi®cantly reduced queen and king palm growth and increased mortality of king palms during establishment. Turfgrass increased drought effects and decreased stomatal conductance of palms. Soils under turfgrass were signi®cantly drier than mulched or unmulched soils. # 2001 Elsevier Science B.V.
