About Big Daddy Hydrangea

The Big Daddy Hydrangea from the Southern Living Plant Collection produces massive eye-catching blooms that are impossible to ignore. Like other Macrophylla hydrangeas, these vibrant mophead bloom clusters are pink if planted in alkaline soils and blue while grown in acidic soils. Expect an extensive initial bloom in early summer, followed by slightly smaller reblooms through fall. Additionally, the Big Daddy proves to be an impressive addition to cut flower arrangements.


When the Big Daddy isn’t in bloom, large serrated leaves will still draw attention. Their glossy surface reflects sunlight beautifully.


Soil alkalizers, such as limestone or hardwood ash, can be used to raise the pH to the desired level, while acidifiers, such as peat moss, can be used to lower the pH.


The Big Daddy Hydrangea reaches a mature size of 5-6′ H x 5-6′ W. It’s guaranteed to shine as a hedge, border, specimen, or container plant.


Big Daddy Hydrangea Care

Hardy in USDA Zones 6-9. In addition, this deciduous shrub will go dormant every winter in every zone.


Plant in Partial or Filtered Sun for best results. The Big Daddy Hydrangea can’t handle extended direct sun exposure, however, too little sun will result in a decreased bloom cycle.


The Big Daddy Hydrangea needs regular watering after planting, around 3-4 times a week for the first few months. During this time, check frequently to ensure that your plant isn’t drying out or staying soggy. Afterwards, you can water less frequently, 2-3 times per week as needed. Once your plant has a couple growing seasons under its belt, it will only need watering during particularly dry periods.


Fertilize in early spring with a balanced fertilizer. Then reapply as instructed by your brand of fertilizer, traditionally in May, and July.


Big Daddy Hydrangea Spacing Recommendations

Space Your Big Daddy Hydrangea 4 feet apart for a seamless planting. Otherwise, plant them 6+ feet apart to leave space between shrubs.
