    Green roofs have positive effects on urban settings, leading to improvements in aesthetics and energy consumption of buildings. However, green roofs are extremely difficult environments for plant growth and survival because water availability fluctuates dramatically and is often limited between dry periods and rain events. We analyzed the effects of different concentrations of a water-retention additive, hydrogel, in green-roof substrate mixtures on the growth and ornamental quality of Mentha suaveolens. Coir and perlite were mixed in the ratio of 80:20 (coconut coir dust to perlite, v/v; referred to as C4 P1 ), 50:50 (C1 P1 ), or 20:80 (C1 P4 ) at a substrate depth of 20 cm. Hydrogel (hydrophilic polymer: medium, w/v; dry weight basis) was added to the substrate mixtures at 0 (control), 0.25, 0.5, 1.0, or 2.0 .. View More»
