This shrub grows slowly to moderately, with annual height gains ranging from less than 12″ to 24″.
Oakleaf hydrangeas grow slowly, right?
Native to the Southeast of the United States, oakleaf hydrangeas (Hydrangea quercifolia) are prized for their voluminous flower clusters and oak-like leaves. These plants are tolerant of USDA plant hardiness zones 5 through 9, but they develop slowly and may not blossom the first year. But with the right care, they bloom fairly predictably once they’re established. A paucity of blooms is typically the result of poor pruning techniques or insufficient watering. Both issues are easily fixable.
Before planting oakleaf hydrangea, work 2 to 4 inches of compost, moistened peat moss, or manure into the soil to a depth of 8 inches. These modifications enhance drainage and increase nutrients, which may encourage wholesome growth and blooms.
A soil test kit, available at nurseries and garden centers, can be used to determine the pH of the soil in your garden. The pH range between 5.5 and 6.5 is ideal for oakleaf hydrangea growth. To make the soil acidic, add sulfur, peat moss, sawdust, or dry leaves. Dig dolomitic lime into the soil to increase the pH.
Particularly in warmer areas, put oakleaf hydrangea in partial shade; the plant won’t thrive in dry, sunny settings and its blossoms may appear faded or burned. In complete shade, the plant could not flower.
To keep the soil equally moist but not soggy, water newly planted hydrangeas every other day or as necessary. In dry conditions, water established hydrangeas more frequently than once per week. Insert your finger into the ground. One inch beneath the surface should feel damp.
Early in the spring, fertilize oakleaf hydrangeas by applying 0.5 ounces of 10-10-10 fertilizer per 10 feet of soil. A surplus of fertilizer promotes lush, green growth rather than floral growth.
Oakleaf hydrangea should be pruned right away after blooming. If you prune an oakleaf hydrangea in the winter or spring, you’ll remove the flower buds and stop the plant from blooming for the season. Oakleaf hydrangeas bloom on old wood.
How long does a hydrangea take to grow to its maximum size?
I’ll address some of the most typical queries about hydrangea plant care in this section. If you can’t find your response here, post it in the comments section and I’ll respond as soon as possible.
Are hydrangeas easy to care for?
Hydrangeas are indeed quite simple to maintain when given the proper growing conditions. They are resilient plants that require little maintenance and will flourish for many years.
How big do hydrangeas grow?
According to the variety. Dwarf species can grow to only a few feet tall, while larger ones can grow up to 15 feet tall. Always look at the plant tag to see the precise size that your chosen hydrangea will reach.
Can hydrangeas tolerate full sun?
In colder climes, certain hydrangeas may be able to endure a placement in full sun. To achieve the greatest results, it’s better to put them where they will receive some partial shade.
How long does it take for a hydrangea to grow to full size?
Hydrangeas take between two and four years to attain their maximum size, despite the fact that they are fast-growing shrubs. Some people mature more quickly than others.
Hydrangeas are easy to grow and are tolerant of almost any climate. The nicest aspect is that you can have a wide variety of those big, beautiful blooms all summer long because there are so many different species. Your hydrangeas will flourish for many years to come with the right care.
What is the duration of an oakleaf hydrangea’s bloom?
All around our land, we have grown oakleaf hydrangeas in both bright and shaded areas. It seems to operate best in the morning sun with afternoon shade. The oakleaf has the advantage of thriving in more drier environments than its cousin hydrangeas. While oakleaf hydrangeas grow with relatively little care, the rounded, vivid mopheads suffer in our sandy soil and frequently wilt on hot days.
Because of rumors that the leaves resemble some oak foliage, Hydrangea quercifolia is often known as oakleaf hydrangea. They certainly look lovely in the fall when they change dramatically from red and orange to burgundy. It is a deciduous shrub that can reach a height of 4 to 6 feet and is upright and very full. It works well as a highly striking specimen plant, a sunny border, or a forest garden that receives some shade.
It is native to the United Regions and is frequently seen in the deep south and neighboring coastal states. On one of his numerous botanical expeditions south in the middle of the eighteenth century, botanist William Bartram is reported to have recorded this species. One of just two native hydrangeas exists. It is quite hardy here in South Jersey and blooms best in regions with moderately warmer summers.
Like other plants, it thrives when planted in good soil, mulched, and watered as needed. The soil needs to be well-drained even if it likes wetness since it cannot endure a stagnant, muddy environment. The ones we have on our property are in our sandy loam, in part shade, and are covered in leaf mulch from our enormous trees every fall, despite the fact that it is believed to flourish in damp soils. They definitely value a summer mulch because it keeps the soil moist. Feed in the spring once a year.
Since they blossom on old wood, if you must prune one back, do it right away to give new growth enough time to develop and bear buds for the following year.
Sally Castellini, owner of Pink Dahlia Vintage Floral Designs in Milliville and a vendor at the Collingswood Farmers Market, discusses how succulent plant terrariums have grown in popularity as wedding décor and walks viewers through how to set one up.
They are adored for its sizable white flower pyramidal bunches. I particularly appreciate picking the big blooms and putting a few in a big vase so I can enjoy them for a long period. They can be harvested and preserved later in the season to enjoy all winter long in a vase or on a wreath when they are almost completely dry on the plant. On mature oakleaf hydrangeas, the bark occasionally peels away to reveal a rich brown covering that looks lovely in the winter.
They are extremely colorful for around nine months out of the year and hardy from zone 5 to zone 9. Despite starting out green, they produce vibrant foliage in the fall. The blossoms start off white in mid-June and gradually turn pink and pastel mauve until drying in the fall.
For extended summer flowers, there are several really attractive hydrangeas that can be planted. Knockout roses, butterfly bushes, Weigela, clethra, kerria, bottlebrush buckeye, and abelia are a few examples of companion plants for mid- to late-summer blooming.
Look into these if you’d want a few plants that bloom continuously throughout the season. The task of planting for continual bloom is definitely worth the effort. An oakleaf hydrangea can be a wonderful place to start because it will bloom from now until the end of the season.
How simple are oakleaf hydrangeas to grow?
Oakleaf hydrangeas are low-maintenance plants that only require the following necessities:
- Location and daylight Oakleaf hydrangeas thrive in full sun to light shade in northern regions. Give them locations with morning sunlight and shade from the harsh afternoon sun in southern climates.
- A rich, well-drained, somewhat acidic soil is ideal for growing oakleaf. When planting, spend time amending the soil in clay-heavy locations. Pennington Quick Reaction Gypsum helps remove compacted soil, enhances water penetration and drainage, and promotes healthy root development. Additionally, Pennington UltraGreen Plant Starter with Vitamin B1 aids in lowering transplant shock.
- Water
- Oakleaf hydrangeas thrive naturally in soil that is consistently damp but never drenched. Water thoroughly, then before adding more water, manually inspect the soil. Avoid overwatering to stop root rot. Wait a few days before making another check if the soil is damp.
- Fertilizer
- Your hydrangeas will start out with the vital nutrients they require when you fertilize them at planting time with a complete fertilizer like Pennington UltraGreen All Purpose Plant Food 10-10-10. Every year, in the first few weeks of spring, feed your oakleaf with the same fertilizer or a fertilizer that promotes flowers, like Pennington UltraGreen Color Blooms & Bulbs Plant Food 15-10-10. then refeed it in the middle of the summer, four months later.
What is the ideal spacing between oakleaf hydrangeas?
Follow these instructions to plant, spacing 4 to 8 feet apart depending on the type. Check the tag on your plant for details on recommended practices.
- Create a hole that is 2-3 times bigger and slightly deeper than the root ball.
- Lick up the soil surrounding the plant’s roots after removing it from the nursery pot.
- Plant it so that the top of the root ball is just visible above the soil line.
- To get rid of air pockets, backfill the hole with soil and lightly tamp it down. Water wisely.
- To keep moisture in and control weeds, use a 2- to 3-inch layer of mulch made from finely chopped bark.
Soil: To prevent root rot, plant in slightly acidic soil with good drainage. Use an exceptional all-purpose potting mix for your containers.
Watering: For optimum flowering and healthy growth, plants require regular watering. Maintain a uniformly wet but not waterlogged soil. To establish robust roots, deeply water the soil. The oakleaf hydrangea may withstand drought better than other varieties.
Apply a granular fertilizer made specifically for trees and shrubs in the early spring as directed on the container. Reapply every year.
Apply compost, shredded bark, or other organic material around plant bases every spring as mulch. After the ground freezes in the fall, pile 6 to 8 inches of mulch around the base for protection over the winter in colder climates. Early in the spring, remove the mulch to let the soil warm up.
What is the rate of hydrangea growth per year?
Hydrangeas (Hydrangea spp.) are widespread attractive garden plants with a wide range of bloom colors, including white, numerous shades of blue and pink, maroon, red, and even pale green. There are dozens of species and even more variants of hydrangeas. Depending on the species, some hydrangeas have enormous, rounded flower heads, while others have smaller, flatter, and more delicate blossoms. Plant hydrangea shrubs in the fall or early spring to give them time to develop a strong root system. With an average annual growth of two feet or more, hydrangeas are quick-growing plants. Be aware that both humans and animals are poisoned by the plant.
How can a hydrangea plant grow faster?
Early spring or mid-July through late summer are the blooming seasons for hydrangeas. The methods for extending hydrangea blossoms’ life and producing more of them are discussed below.
Plant the hydrangea where it will receive morning light and afternoon shade, keep the soil continuously moist, and treat it in the spring with a fertilizer that is well-balanced to encourage more flowers. To encourage more blossoms, don’t prune your hydrangea too frequently. Hydrangeas bloom on the growth from the previous year.

Do hydrangeas grow slowly?
There are a few things you need to know about hydrangeas’ growth when you grow them. So that you know exactly what to anticipate from your Hydrangeas’ growth, let’s look at these items.
Be Patient with Your Hydrangeas
You need to be patient with hydrangeas as a plant. After being planted, these plants take a while to mature and make a solid foundation for themselves in your yard. Since these plants grow slowly, you might not see much development from them, particularly in the first few years.
To better comprehend the growth you may anticipate from these plants, let’s walk through the first few years of hydrangeas’ development.
If your hydrangeas grow at all above ground when you initially acquire them and plant them in your garden, you shouldn’t anticipate seeing much growth from them. However, just because you aren’t able to observe any growth at this time doesn’t mean that no growth is taking place.
Your hydrangeas will begin to establish themselves in the first year they are in your yard by spreading out their roots and building a strong base for themselves. Because of this, it’s crucial to keep children hydrated at this time.
Your hydrangeas may begin to grow a little above the ground in the second year. If you are not paying close attention to your plant, you might not see this growth at all.
Your hydrangeas will then likely take off and exhibit amazing growth in the third year because they are still young and weak. Therefore, if your Hydrangeas are young and have not yet shown any growth, do not become alarmed as this could be typical.
If you give your hydrangeas all they require, they will be OK and start growing healthily. Therefore, never give up on your hydrangeas and practice patience.
Ensure You Know Your Hydrangeas Type
Make sure to identify the precise type of hydrangea you are cultivating if you experience problems with its growth. This is due to the fact that some hydrangeas don’t initially develop to be particularly large while others can.
So, depending on the type, if your hydrangea isn’t growing, it may have reached the maximum size it can, which is why it won’t. Make sure to purchase and plant the appropriate Hydrangeas that will grow to that height if you want yours to be large and tall.
Beware of Harsh Winters with Hydrangeas
A harsh freeze in the winter will have an impact on some hydrangeas since they are not immune to freezing temperatures. Your hydrangeas’ old wood and the new growth that is just starting to emerge just below the soil’s surface could be harmed if the temperature falls below 41F (5C).
Your plant’s general growth may be impacted, and it is possible that it won’t grow very much the next growing season. Therefore, if you are aware that your winters are unusually severe, you should provide your Hydrangeas with protection before the cold weather arrives.
Do oakleaf hydrangeas tolerate complete shade?
Oakleaf hydrangeas like midday shadow because they are understory plants in their natural habitat, especially in southern climes where nearly full shade may be required. Oakleaf hydrangeas may tolerate full sun in the North. The intensity of the fall color could be diminished by too much shade.
