Ornamental Plant Growth Regulators (PGRs)

Professional Plant Growth Regulators for Trees, Shrubs & Ornamentals

Ornamental plant growth regulators (PGRs) help landscape professionals, arborists, nurseries, and growers manage excessive vegetative growth while improving plant appearance, root development, and stress tolerance. These products are widely used to reduce pruning frequency, improve plant density, and maintain healthier, more attractive ornamental plants in commercial and residential landscapes. Our collection of professional-grade ornamental PGRs includes soil-applied and foliar plant growth regulators designed for use on trees, shrubs, nursery stock, hedges, and landscape ornamentals. Products featuring active ingredients like paclobutrazol help suppress excessive top growth by inhibiting gibberellin biosynthesis, redirecting plant energy into stronger root systems and improved plant health.
