Two experiments were conducted to evaluate commonly used granular preemergence herbicides applied prior to the sticking of cuttings in propagation. Rooting percentage of the three cultivars, `Trouper' azalea, `Hino-Crimson' azalea, and `August Beauty' gardenia, was not affected in experiment 1. However, all three species exhibited some reduction in root quality or root length with all herbicides. In general, the herbicides with the least suppression were: Ronstar, Southern WeedGrass Control, OH-2, Snapshot 2.5 TG, and Rout. The second experiment with `August Beauty' gardenia evaluated the effect of cuttings depth in overcoming the negative herbicide effects on root development. The results were similar to those obtained in experiment 1.
