Do Hydrangeas Bloom In Cycles?

Hydrangeas bloom differently depending on their variety and climate. Old wood-blooming varieties typically bloom in spring or summer, while climbing hydrangeas are hardy in zones 4-8. To ensure proper growth, it is essential to refer to the nursery tag before planting. Large, flat-bloom clusters of fragrant white flowers emerge in late spring through mid-summer. Climbing hydrangeas are hardy in zones 4-8 but are somewhat borderline in the lowest and highest zones.

Fertilizing mature hydrangeas annually with an NPK 15-10-10 or 10-5-5 fertilizer is crucial. Soil pH levels can alter the flower color of some species and varieties, such as acidic soils. Hydrangeas can bloom for about 10-12 weeks, depending on their type and care. Some hydrangeas wait until the end of summer to begin their show, while others are some of the first shrubs to bloom in the spring.

Hydrophusas bloom seasonally and typically start to bud around mid-summer or late summer. Under ideal conditions, hydrangeas will bloom all summer long, with flowers appearing in mid to late spring and lasting until early fall. Some hydrangea blooms change color as they fade, creating interest well into fall and winter. Hydrangeas have a long flowering season, meaning they can be enjoyed for several months after starting to bloom.

Reblooming hydrangeas occur once annually, but there are reblooming varieties. Proper care, hardiness, fertilizer, soil, winter protection, and proper pruning can ensure your hydrangea will bloom next year.
