Weed management in landscape plantings is a challenging task because it consists of
a mixture of annual and perennial ornamentals in landscaped area. This project aimed
to examine responses of ten common ornamental crops from various families to citraltreated
lemongrass (CTL) mulches and to determine the potential of CTL for weed
control in landscapes. A total of 3.5 t ha -1 CTL mulches will be applied to the ornamental
plants in pots under glasshouse conditions. In the field, the CTL mulches will be applied
in planting boxes grown with two selected ornamental plants. Weed density, weed
area and visual score of the ornamental crops will be assessed monthly for three
months. It is expected that the CTL mulches provide excellent weed control without
injuring any ornamental crops within three months. The findings of this study will lead
to development of novel and environmental friendly approach for sustainable weed
management in landscapes.
