The demand for groundcover plants in residential and commercial landscapes is increasing due to several reasons, such as aesthetic appeal of masses of these low-growing plants in small- to medium-sized areas of the landscape, enhanced environmental

N immobilization, and soil or groundcover management ( Haynes, 1988 ; Merwin, 2003a ; Merwin et al., 1996 ). A seasonal pattern of nitrate-N losses through leaching has been observed in fertilized orchards with higher N losses during times of year

Groundcover rose is one of the most widely used roses in public spaces. Being relatively low maintenance, and having resistance to pests and diseases, winterhardiness, a long blooming period, and compact growth make them an ideal ornamental plant

Landscape maintenance in Hawaii occurs year round. Many popular groundcovers are pruned monthly, some twice monthly. This increases labor costs and creates large amounts of waste. Several rates of five commercial growth regulators (cimectacarb, flurprimidol, mefluidide, paclobutrazol, and uniconazole) were applied to several groundcovers commonly grown in Hawaii. Species used include Cuphea hyssopifolia, Evolvulus glomeratus, Lantana montevidensis, Myoporum spp., and Wedelia trilobata. Studies were conducted in the shadehouse with potted plants and in the field with established plants. Rates, response, and method of application (spray or soil drench) for each product were evaluated. Growth, length of control, and phytotoxicity were measured. Flurprimidol, paclobutrazol, and uniconazole showed the greatest control for the most species. Flurprimidol and paclobutrazol controlled growth for the longest time, up to 4 months for some species. However, these materials resulted in the greatest amount of damage, even at low rates. Cimectacarb controlled growth of fewer species, while mefluidide caused the least growth reduction for all species.
