A water-soluble granular composition including at least 40% of at least one plant growth regulator, at least one binder, at least one disaccharide and at least one surfactant; as well as methods for making and using the composition are disclosed. The water-soluble granular composition advantageously improves preparation of a solid plant growth regulator formulation for spray application, as such composition swiftly dissolves, is easily metered for application, can be more highly concentrated and is dust-free. A presently preferred water-soluble granular composition includes at least 40% of at least one gibberellin as the plant growth regulator.
