Do hydrangeas bloom more than once a summer?

Hydrangeas are beautiful flowering plants that can bring color and life to any garden or landscape. One common question that many people have is whether hydrangeas bloom more than once a summer. The answer to this question depends on the type of hydrangea you have.

Regular hydrangeas, also known as mophead or bigleaf hydrangeas, typically bloom once per season. These hydrangeas produce large, round flower clusters in shades of blue, pink, or white. They bloom on old wood, which means that the flower buds are formed in the previous year and stay dormant during the winter months. In the spring, these buds start to grow and eventually open up into beautiful flowers. Once the flowers have bloomed, they will gradually fade and eventually die off. This is a natural part of the plant’s life cycle.

On the other hand, there are also reblooming hydrangea varieties that have the ability to produce a second set of flowers later in the season. These hydrangeas, such as the Endless Summer series, bloom on both old and new wood. This means that they have the ability to produce flower buds on the previous year’s growth as well as on new growth that occurs during the current growing season. As a result, they are able to bloom more than once in a summer. The reblooming hydrangeas typically produce their first flush of flowers in early summer, and then continue to produce new flowers throughout the rest of the season.

The ability of hydrangeas to rebloom can be influenced by various factors, including the climate, pruning practices, and overall plant health. In regions with mild climates, reblooming hydrangeas may have a better chance of producing a second set of flowers. However, in colder climates where the winters are harsh, the flower buds on the previous year’s growth may be damaged or killed off, reducing the chances of reblooming.

Pruning hydrangeas also plays a role in their ability to rebloom. Regular hydrangeas should be pruned immediately after they finish blooming in order to allow enough time for new buds to form on the old wood. If you prune them too late in the season, you may end up removing the buds for next year’s flowers. On the other hand, reblooming hydrangeas can be pruned in early spring or even in late winter before new growth begins. This allows you to shape the plant and remove any dead or damaged wood without sacrificing the potential for reblooming.

In terms of plant health, it is important to provide hydrangeas with the right growing conditions and proper care. Hydrangeas prefer well-draining soil that is rich in organic matter. They also require regular watering, especially during dry spells. Providing them with a layer of mulch around the base of the plant can help to conserve moisture and regulate soil temperature. Additionally, fertilizing hydrangeas with a balanced, slow-release fertilizer in early spring can promote healthy growth and abundant blooming.

In my personal experience, I have had both regular and reblooming hydrangeas in my garden. The regular hydrangeas always provided a stunning display of flowers in early summer, but their blooms would gradually fade and not return until the following year. On the other hand, the reblooming hydrangeas continued to produce flowers throughout the summer, bringing continuous beauty to my garden. I found that proper pruning and care played a key role in encouraging the reblooming hydrangeas to produce a second set of flowers.

To sum up, regular hydrangeas typically bloom once per season, while reblooming hydrangeas have the ability to produce a second set of flowers later in the season on new stems. The ability of hydrangeas to rebloom can be influenced by factors such as climate, pruning practices, and overall plant health. By providing the right growing conditions and proper care, you can encourage your hydrangeas to bloom more than once in a summer, adding beauty and color to your garden throughout the season.
