Bonzi Plant Growth Regulator jug (2.5 gal)

Bonzi Plant Growth Regulator is a professional plant growth regulator designed to produce compact, uniform, and highly marketable ornamental plants. Powered by paclobutrazol, Bonzi reduces internode elongation to control excessive stretch while promoting stronger stems, deeper green foliage, and improved overall plant appearance. Ideal for greenhouse and nursery production, Bonzi helps growers produce well-proportioned crops that are more durable during shipping and display. Its flexible application methods allow use as a foliar spray, drench, sub-irrigation treatment, or pre-plant bulb soak for precise growth management across a wide range of ornamental crops. Bonzi is widely trusted for bedding plants, annuals, perennials, flowering crops, woody ornamentals, and bulb crops where consistent plant size and premium visual quality are essential.
