Pruning hydrangeas before winter is crucial for their health and beauty. Most hydrangeas in North America fall into one of five types: bigleaf, mountain, smooth, panicle, and oakleaf. Some form flower buds on old wood, while others form buds on new wood once they begin to grow. To ensure your shrub blooms next spring, follow these steps:
Winterize your shrubs: Most pruning is carried out in late winter or early spring. However, climbing hydrangeas are pruned after flowering in summer.
Trim bigleaf hydrangeas back to a set of healthy buds after the flowers have faded, in late summer, before the plant begins to go dormant. Use sharp, clean trimmers to cut stems just higher than a pair of leaves. For a heavier prune, remove gray, older, or dead stems during the winter.
Cut back bigleaf hydrangeas in late winter before new growth begins. To get bigger flowers, cut them all the way back. To reduce flopping, leave a framework of leaves. Hydrangeas that bloom on new wood can be safely pruned in late fall once the plants have gone dormant or in early spring.
Prune back stems to just above a fat bud (heading cut) in fall, late winter, or spring. These plants have conical-shaped flower heads that provide good foliage.
Trim about a third of the stems a little harder down the stem to get good foliage and prune the rest for big flowers in summer. Knowing your hydrangea type is essential for planning winter care and ensuring your shrub blooms next spring.

What does hydrangea look like in winter?
Hydrangeas, a popular deciduous shrub in gardens across Britain, are known for their vibrant, plump blooms. However, in winter, their delicate petals fade, causing them to appear dry and brown. To ensure their return in April, they need targeted care. Hydrangeas come in various shapes, including circular balls and graduated cones. The most iconic variety is the large rounded flower heads, but double-flowers and bi-colored varieties can also be grown as climbers or in containers. As winter approaches, it’s crucial to prepare your hydrangeas for the new season.
How long do hydrangeas last in the ground?
Hydrangeas are long-lived shrubs that can live for up to 50 years if properly cared for. They prefer morning sun but afternoon shade and require frequent watering during the growing season. Bigleaf hydrangeas, also known as common hydrangeas, bloom in blue, pink, and purple colors and bloom earlier than other varieties. They can change their bloom colors based on soil properties, with blue flowers being more common in alkaline soils and pink blooms in alkaline soils.
Cultivars like “Ayesha”, “Nikko Blue”, and “Preziosa” are available. Smooth hydrangeas bloom longer, showing color from early June through September. Cultivars like “Anabelle” and “Invincibelle Spirit” are available. Smooth hydrangeas bloom on the current year’s wood, so pruning them severely is necessary. Cutting them down to within 6 to 12 inches of ground level is recommended.
What is the mistake for pruning hydrangeas?
Pruning hydrangeas is best done in late winter and early spring, making it a good weekend job during March. Pruning after winter frosts protects the plant from winter injury. Climbing hydrangeas should be left until early summer, as they produce flowers on old wood. Pruning too early may remove new buds before they bloom. Tom’s Guide offers expert editors to keep you informed and prepared for the prime growing season by pruning your hydrangeas at the right time.
What happens if I forget to prune my hydrangea?
If you forget to prune your hydrangeas for a year, they may grow too big, tangled, or have smaller, less showy flowers. To restore their beautiful shape, you can use proper pruning techniques, such as using sharp secateurs. Felco secateurs are a good choice, and even good secateurs can become blunt after a season, so sharpening them with a sharpening stone can help maintain their strength. Remember to use a good pair of secateurs for optimal results.
How do you preserve hydrangeas for the winter?
Hydrangeas are a beautiful and easy-to-preserve flower that can last up to a year. To dry them, hang them upside down in a cool, dry location, allow them to dry naturally on the stem until the petals feel papery, or use a mixture of water and glycerin. The ideal time to cut hydrangea blooms to dry is towards the end of their growing season (August through October), when the larger petals are starting to change color and develop a papery feel, and the tiny flowers are just beginning to open. This method helps maintain the flowers’ shape and color, ensuring their beauty is preserved long after they bloom.
What is the best month to prune hydrangeas?
Hydrangeas are typically pruned in late winter or early spring, with climbing hydrangeas being pruned after flowering in summer. Hydrangeas bloom from mid- to late summer, while mophead and lacecap hydrangeas bloom satisfactorily with little attention. Annual pruning encourages new growth and better flowering display. Other species, including climbing hydrangeas, benefit from a trim. Timing is usually late winter/early spring, but sometimes late summer. Pruning hydrangeas can be easy to moderate.
Should hydrangeas 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 I cut my hydrangea down to the ground?
To rejuvenate a hydrangea plant, it is recommended that the stems be cut close to the ground, as the bloom buds are produced on the older wood. It is recommended that up to one-third of the older stems be removed each summer. This practice will result in a reduction of the floral display in the spring and summer months.
How do you winterize hydrangeas?
In late fall, it is advisable to undertake a series of preparatory tasks in order to ensure the health and vitality of your garden over the winter months. These include the removal of excess organic matter, the application of water prior to the arrival of the first frost, the pruning of plants to encourage growth, the addition of a thick layer of mulch to retain soil moisture and the wrapping of plants in protective material.
When should I cut the head off hydrangeas?
Pruning hydrangeas is typically done in late winter or spring, except for climbing hydrangeas which are pruned in summer. Different types of hydrangea require different pruning techniques. To identify the type of hydrangea, wait for its summer flowering and prune it the following year. If unsure, leave it unpruned for a year. The following list shows the most common types of hydrangea found in gardens:
Can hydrangeas be cut back hard?
Hydrangeas, including Hydrangea macrophylla, Hydrangea aspera, Hydrangea serrata, and Hydrangea quercifolia, can be lightly pruned by cutting back old flower heads to a pair of buds below. Hydrangea paniculata and Hydrangea aborescens can be harder pruned. If you’re unsure which type of hydrangea you have, deadhead it and observe its growth. If it produces flowers on this year’s growth, prune it harder next year. Mophead and lacecap hydrangeas (Hydrangea macrophylla) flower on previous year’s growth, so pruning them after flowering is not recommended.
The cork-like structure of hydrangea stems makes it best to leave cutting back until spring, as they hold enough moisture during winter to freeze in frosty weather. Pruning them in autumn after flowering can freeze the buds, killing the stems and their buds. Leaving old flowers on the plant over winter helps protect the stems and their new buds. Once sap starts to rise in spring, buds will open, and many should carry blooms the following year.

Can you do one for the macrophylla/lace cap types, as they flower on old wood? I have inherited a very large overgrown one and would like to rejuvenate it, so was going to prune lightly in Feb, but also take out ⅓ of the branches much lower to encourage new growth to flower a year later. Does that sound right?
