Make cuts at the base of each branch where it meets the main stalks with sharp pruning scissors. Between cuts, take a step back to assess the overall contour. To keep the oakleaf hydrangea balanced, prune from all sides.
Can you cut oakleaf hydrangea to the ground?
The oakleaf hydrangea blooms in whites and creams with cone-shaped flowers. Its leaves are deeply cut and resemble those of an oak tree. It’s a hardy shrub that thrives in both full sun and full shade.
H. quercifolia blooms on old wood, or growth from the previous season. Unless it is injured or overgrown, it does not require pruning. Remove the dead flower heads slightly beneath the bloom if you want to clean it up.
Remove a few of the oldest, thickest stems all the way to the ground if your oakleaf hydrangea is really old and woody. However, because it blooms on old wood, cutting the entire plant to the ground will result in the loss of an entire season’s worth of blossoms.
Should I deadhead oakleaf hydrangea?
To ask which of my plants is my favorite is like asking which of my children is my fave! A difficult topic to answer, but since I’m not in danger of hurting sensitive young egos, I’d have to say the oakleaf hydrangea is one of my favorites (Hydrangea quercifolia). The reason for this is that this is a plant that has four distinct seasons of appeal. That appeals to me since it saves me time, energy, and money. It rewards me in the spring, summer, fall, and winter once it has established.
Hydrangea quercifolia is a shrub that grows to be around six to eight feet tall, with a maximum height of ten to twelve feet. The huge, dark green leaves have silvery undersides and resemble the Northern Red Oak, from which it receives its popular name. It can be grown in zones 5 through 9.
Cone-shaped flowers can grow up to a foot in length. The blossoms start out white, then acquire a pink blush before turning red as the seasons pass. Single or double florets might be found.
Although the spring and summer are lovely and lush, I am looking forward to the warm days and cool nights of October and November, when the flowers change red and the foliage takes on a variety of yellow, orange, red, brown, and burgundy hues. In protected areas, the leaves last for a long time before falling to reveal an uneven branching structure of cinnamon-colored peeling bark. The contrast against a snowy white bedspread is breathtaking.
Oakleaf hydrangeas thrive in hotter climates, but they like some afternoon shade. It can be grown in full sun in its northern range. The more sun exposure you get, the more flowers you’ll receive, and the more stunning the fall color will be.
This shrub can survive drier soil than its mophead relatives, but not wet feet. Plant it in acidic, wet, well-drained soil supplemented with compost or other organic matter. It can be used as a specimen feature in the landscape or as a mass planting in shaded wooded regions.
Pruning is rarely essential, although it should be done after the flowers have faded and before August. Late summer and early fall are the best times to plant flower buds for the next year. By simply snipping off old flowers, you can “deadhead” them at any time. I like to leave the blossoms on the plant throughout the winter months so that I may enjoy them.
You can cut longer stems for flower arrangements before August if you’re cutting blossoms for arrangements. After that, only remove short stems to avoid losing next year’s blooms.
Oakleaf hydrangeas are generally pest and disease free. This is another bonus in my eyes because it means that plants will look and perform their best all year long without the need of chemicals (always a last resort in my book).
The double flowered variety ‘Snowflake’ is arguably the most popular. Its creamy white blossoms can reach a length of a foot.
In the spring, the foliage of ‘Little Honey’ turns golden, then chartreuse, then green, with a gorgeous burgundy red fall color.
Oakleaf hydrangeas are a perennial favorite in my yard. They’re lovely all year with stunning leaves, exquisite flowers, and fascinating bark, and they’re hardy in many regions of the country. They’re pest and disease resistant, bloom in the shade, and are very little maintenance. What more could we expect of a plant for our landscapes and gardens?
How do you prepare oakleaf hydrangeas for winter?
When the plant is dormant and won’t be harmed by higher temps, plant young oakleaf hydrangeas in the late fall or early spring. The leathery leaves become purple, orange-bronze, or crimson in the fall, and the hue is appealing. Winter color and texture are also provided by the peeling, exfoliating branches.
Why are my oak leaf hydrangeas not blooming?
Oakleaf hydrangeas (Hydrangea quercifolia) are prized for their huge clusters of flowers and oak-like leaves. They are endemic to the southeastern United States. These plants are hardy in USDA plant hardiness zones 5 through 9, but they grow slowly and may not blossom the first season. When properly cared for, they bloom quite predictably once established. Inadequate water or poor trimming procedures are the most common causes of a lack of blooms. Both can be easily corrected.
Does oakleaf hydrangea bloom on old wood?
Some hydrangeas, like Limelight green hydrangea, bloom every year on new wood. Oakleaf hydrangeas, on the other hand, bloom on old wood from the previous year.
Before you enjoy the blooms, the buds that will become beautiful oakleaf flowers form on stems in the summer. Always prune oakleaf hydrangeas as soon as they complete flowering to prevent the formation of next year’s buds. If you wait too long, you can lose all of the bloom buds you’re hoping for.
An oakleaf hydrangea may provide beauty to your house and landscape every month of the year, whether you grow in a little space or have plenty of room. Pennington is here to help you take your landscape and garden to new heights all year long with timely advice and superior lawn and garden products.
When should I cut the flowers off my hydrangea?
If it blooms on old wood (stems from the previous summer), its buds are forming, and if you wait too long, you may chop them off, resulting in no flowers the next spring. As a result, these bushes should be cut as soon as their blossoms fade.
When should hydrangeas be cut back?
Which group the plant belongs to determines the timing and degree of pruning:
- As the days become shorter and the temperatures cool in the late summer and fall, buds for next year’s blooms form.
- By cutting out dead, diseased, or broken branches, a simple trimming is usually all that is required to preserve shape, size, and a healthy plant. Pruning that is too harsh should be avoided.
- Trimming should begin as soon as flowering has stopped in the summer, but no later than August 1. Pruning in the fall, winter, or spring may result in the removal of new buds.
- When the leaves emerge in the spring, tip-pruning the branches encourages several, smaller flower heads rather than fewer, larger flower heads.
Can I cut flowers off my hydrangea?
Nothing beats having your own fresh-cut Hydrangea stems in a vase where you can see them all of the time. After all, we worked hard to create these floral plants to beautify the outside, so why not bring them inside as well? But how do you get the most blooms from your Hydrangea plants for a vase or arrangement?
You’ll need to water the plant the day before and cut the stems the next morning to cut Hydrangea blooms for a vase. Just above a leaf node, make a straight cut across the stem. Then remove the leaves from the stem, recut it at an angle, and slice the base vertically. Place it right away in a bucket of lukewarm water.
It’s not difficult to learn how to make a beautiful cut flower arrangement out of Hydrangea bushes. Knowing when to take your cuttings, how to select and cut the blooms correctly, and how to condition them for a vase or arrangement may all make a great difference.

Where do you cut back hydrangeas?
In the fall, late winter, or early spring, cut down stems to just above a big bud, known as a heading cut. The flower heads of these plants are conical in shape. To offer some winter interest in your landscape, I advocate leaving the dry, tan flower heads on the plant, so I wait until late winter or spring to cut these. Here are a few of my favorite panicle hydrangeas:
