This product might appeal more to general plant enthusiasts rather than those specifically looking for a fertilizer tailored to hydrangeas, as it does not specify its N-P-K ratio or detail its content of soil pH adjusters or micronutrients crucial for hydrangeas. Additionally, it is a synthetic fertilizer, which may not appeal to those looking for organic options.
