When Are Hydrangeas In New Hampshire In Bloom?

Hydrangea blooming in New Hampshire depends on two main factors: the location of the plant and the weather. Longer days trigger the plant to bloom in early summer, with their sturdy, long-lasting blooms often fading from one color to another as the season progresses. Hardy Hydrangeas that bloom on new wood are safe picks for the New England region as their flowering buds will not be sacrificed to late frost.

Smooth hydrangeas, native to Eastern North America, are well suited to most New Hampshire gardens due to their mounded growth habit and white to pale pink flowers. They bloom primarily in the summer, with some varieties blooming in the spring and fall. The exact time that blooming begins depends on the weather, as they flower sooner in warmer months.

This year is a banner year for hydrangeas from New Hampshire all the way down to the Mid-Atlantic states, with vibrant orbs of colorful clustered petals. Wet summers and warm winters make for good hydrangeas, as plants form flower buds for the next year in mid to late summer. Hydrangeas are fuller than ever in the U.S. Northeast and New England, thanks to a perfect set of weather conditions.

To ensure your hydrangea will bloom next year, follow expert hydrangea care tips and tricks, such as proper care, hardiness, fertilizer, soil, winter protection, and soil. The macrophylla or endless summer hydrangea variety blooms best on previous years’ “Old wood” but will also bloom, although much less effectively.

Why are hydrangeas so popular in Massachusetts?

Cape Cod, Massachusetts, is known as a hydrangea haven due to its temperate climate, sandy soils, and coastal influences. The region has numerous gardens and nurseries dedicated to these beautiful blooms. The Cape Cod Hydrangea Festival, a collaborative effort between local gardeners, nonprofit organizations, and businesses, celebrates hydrangeas in private gardens not typically open to the public.

Do hydrangeas like sun or shade?

Hydrangeas thrive in full sun to part sun, but can also tolerate some shade. They can be in full shade during the hottest part of the day, especially in hotter climates. However, insufficient sun can lead to reduced flowering and weaker stems. To ensure hydrangeas thrive in their gardens, consider the timing and type of shade. Some hydrangeas are more shade-tolerant than others, so don’t let a little shade hinder your gardening goals.

Why has it been a remarkable year for hydrangeas in New England?

Plants form flower buds in mid to late summer, requiring regular rain throughout the year. The Cape Cod Hydrangea Festival celebrated its 10th anniversary this year, showcasing the abundance of hydrangeas due to their continuous blooming. Hydrangeas go dormant in winter to avoid cold weather, but they are not safe from deep freezes. Consistent, gradual temperatures with no sudden drop from warm to deep freezes are necessary, rather than unseasonably warm or flash freezes. This ensures the continued growth and blooming of hydrangeas.

Do hydrangeas need to be cut back for winter?

Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that can be pruned back to just above a fat bud in fall, late winter, or spring. These plants produce buds in late summer to early fall, which will form next year’s flowers. To maintain winter interest in your landscape, it is recommended to wait until late winter or spring. Popular panicle hydrangeas include Quick Fire®, Limelight, and First Editions® Berry White®.

Should you deadhead hydrangeas?

Deadheading is a technique employed to maintain the color of the “Endless Summer” hydrangea, enabling it to continue blooming throughout the summer and fall seasons.

Why isn’t my hydrangea blooming?

Hydrangeas often fail to bloom due to various factors, including incorrect pruning, bud damage from winter or early spring weather, location, and excessive fertilizer. Hydrangea varieties can bloom on old wood, new wood, or both. For example, a Nikko Blue Hydrangea produces blooms in the fall, which should not be pruned to the ground in the fall when cutting back perennials. Endless Summer, a hydrangea variety that blooms on both old and new wood, should not be pruned in the fall as it may cut off some of next spring’s blooms.

The plant tag on the hydrangea will indicate whether the plant blooms on old wood, new wood, or both. It is best to wait and prune your hydrangeas in the spring, as stems that lack leaves and are brittle when bent should be pruned near the base of the plant, as they will not produce any blooms.

When to prune hydrangeas in New Hampshire?

It is recommended that pruning cuts be made one quarter inch above the first set of live buds in spring, in anticipation of new growth in bigleaf hydrangeas.
