Frequently Asked Questions

Does BloomStruck Hydrangea bloom on both old and new wood?

  • Yes, BloomStruck Hydrangea blooms on both old wood from last season and new growth that emerges from the ground. This dual blooming habit ensures continuous flowers from late spring through fall, unlike traditional hydrangeas that only bloom on old wood. You'll see the first flush on overwintered stems, followed by repeat blooms on current year's growth.

What are the sunlight requirements for Endless Summer BloomStruck Hydrangea?

  • BloomStruck Hydrangea thrives in partial shade and can even bloom in shadier conditions than most hydrangeas. This variety tolerates morning sun with afternoon shade beautifully. Plant where it gets 4-6 hours of sunlight daily for best blooms, available at naturehills.com.

How do I care for BloomStruck Hydrangea, including watering and fertilizing?

  • Water regularly but ensure good drainage, as BloomStruck hydrangeas prefer consistently moist soil. Fertilize in early spring with a balanced fertilizer when flower buds emerge. Apply lime for pink blooms or sulfur for blue flowers to adjust soil pH and achieve your desired color.

What are the shipping options or seasons for ordering BloomStruck Hydrangea online?

  • BloomStruck Hydrangeas are typically available for spring and fall planting seasons when shipped bareroot or potted. Since flower buds emerge in early spring, fall planting gives the best establishment time. Order early in your preferred season for the widest selection and optimal planting timing.

Is BloomStruck more heat-tolerant than other bigleaf hydrangeas?

  • BloomStruck hydrangeas offer improved heat tolerance compared to traditional bigleaf varieties, thriving in both sun and shade conditions. Their disease resistance and ability to bloom on both old and new wood makes them more resilient overall. Shop at Nature Hills for this hardy, reblooming variety.

What soil pH determines the flower color (blue or pink/purple) on BloomStruck?

  • Acidic soil (pH below 7) produces blue flowers, while alkaline soil (pH above 7) creates pink and purple blooms on BloomStruck hydrangeas. Add sulfur to lower pH for blue flowers, or add lime to raise pH for pink tones.

Is my planting zone suitable for BloomStruck, like Zone for New Orleans, LA?

  • BloomStruck hydrangeas are hardy in USDA zones 4-9, so they'll thrive in New Orleans' zone 9b climate. The super hardy nature of this variety means it can handle your hot, humid summers while still producing continuous blooms. Plant in morning sun with afternoon shade to protect from intense heat.
