Which Inorganic Fertilizer to Choose

Typically hydrangeas thrive when fed an all-purpose, balanced fertilizer like a 10-10-10 N-P-K or 12-4-8 N-P-K.

Hydrangeas benefit from applying fertilizer in mid-to-late spring and additional intervals recommended by the manufacturer of the fertilizer you choose to use. While the first set of flowers start to fade, apply the same slow-release bloom-boosting fertilizer used in spring. Time-release fertilizers usually need to be reapplied every three months.
