If you want seriously impressive summer hydrangea blooms, this is how to fertilize them now

  1. When to Fertilize

      • Late Spring to Early Summer (Second Feeding): Boost bloom development with a water-soluble or granular fertilizer.
      • Mid-Summer (Optional): For prolonged blooming, apply a light feeding
