The traditional hydrangea blooms, which resemble clouds, enchant people in North Carolina all through spring and summer. It’s not surprising that a lot of gardeners decide to place the bushes with their eye-catching pink, blue, lilac, and white blooms close to their front doors as a subtly welcoming gesture. But despite how approachable the hydrangea seems, many inexperienced gardeners are put off by the thought of raising the attractive plant. How can you make sure your hydrangeas shine next year this fall? Commercial and Consumer Horticulture Extension Agent Amy Ballard in Davidson County has some advice.
1. Finish some homework.
Learning about your plant is the greatest place to start. some varieties, or “Varied hydrangea varieties result in a different bloom type, according to Ballard. The most popular variety is the mophead hydrangea, which is known for its recognizable fluffy head of blooms. Similar-looking flowers with a little bud in the middle are produced by lacecap hydrangeas. The oakleaf hydrangea might be for you if you prefer a plant with a cone-shaped form.
2. Recognize the ideal plot.
“Ballard thinks that careful site selection is essential. Pick a location that gets the right amount of sun and drainage. The Southern belles of the plant kingdom, hydrangeas like the sun but prefer dappled shade during the sweltering afternoons.
3. Check the soil’s quality.
According to Ballard, soil pH has a significant impact on nutrient solubility as well as hydrangea bloom color. While flowers grown in alkaline soil are darker, those grown in acidic soil are more brilliant. Ballard advises adding aluminum-sulfate chemicals to the soil to make the soil more acidic in order to cause pink blossoms to turn purple. These products can be found at most garden supply stores.
4. Discover the ideal fuel.
Ballard advises using a fertilizer made specifically for hydrangeas, but says a 10-10-10 fertilizer is an acceptable substitute. In order to make sure that the nutrient percentages are in alignment for a healthy bloom, it is best to dose according to the findings of your soil test.
5. Apply the mulch gently.
Mulch aids in soil moisture retention and keeps invasive plants at bay, however it is possible to overmulch. Ballard advises keeping the crown of the plant about an inch away from the mulch and limiting the depth of the mulch to two to three inches. Pine straw is an excellent alternative because it doesn’t change the pH of the soil; pine bark will also work but may lower the pH, necessitating the need for another soil test after about a year.
6. Become a careful pruner.
Hydrangeas may not even require pruning if given enough space to spread out. As your hydrangea bush grows, anticipate it spreading out and plant accordingly. The greatest strategy for preventing over-pruning is to continue deadheading as soon as a bloom starts to fade. Ballard advises trimming back some of the uneven edges in the late fall if you discover your plant is growing unevenly.
7. Save the cuttings to plant heirloom varieties.
Hydrangea stems lengthen and bud more in the spring. Conditions are ideal for developing a whole new plant at this time. Simply remove a stem from the plant, dust it with growth hormone powder, submerge it in water, and plant it in the ground.

Do hydrangeas grow well in North Carolina?
In Eastern North Carolina, any kind of hydrangea can be cultivated, but they do demand evenly moist, well-drained soil.
With morning sun and afternoon light shade, they thrive.
The French hydrangea (macrophylla) and oakleaf hydrangea are the two most common varieties (quercifolia). There are two main flower types on French hydrangeas. The ones known as “mopheads” feature enormous, spherical or conical clusters of lovely flowers with much smaller, seed-producing flowers beneath them. With clusters of tiny seed-producing flowers and bigger showy blooms surrounding them, lacecap types have quite a different appearance.
Depending on whether the soil is acidic (pH < 6) or alkaline, both types have different colors (pH above 7). Blooms can range in color from a light blue to a deep purple in acidic soil, which is more prevalent in our region. Pink hues are frequently produced by alkaline soils. On one plant, you might even see both blossom hues. And while it is possible to modify some plants' bloom colors, I would advise sticking with what nature provides.
While French cultivars are in flower right now, oakleaf hydrangeas bloom in the late spring (early summer). The Endless Summer series is one of the rebloomers that will continue to bloom throughout the summer.
Knowing whether your hydrangea will bloom on this year’s new growth or last year’s old growth is crucial. This is important because if you prune your shrub in the late fall or early winter, you risk removing the buds for this year’s blossoms, and then you’ll wonder why your plant isn’t giving you flowers. Hydrangeas currently require very little trimming, other potentially shortening errant branches and getting rid of any dead wood. The ideal times to prune are as follows: pruning once-blooming French hydrangeas in the summer; pruning reblooming hydrangeas in the winter; and pruning oakleaf cultivars in the summer.
The lovely autumn foliage of oakleaf hydrangeas, which becomes a vibrant scarlet, is another advantage of these plants.
Therefore, even if you don’t have any of these lovely plants in your yard, you may still enjoy the blooming plants that are currently visible across the city.

In the summer, hydrangeas, which are deciduous shrubs, can add lovely blossoms to any Southern garden. Hydrangeas come in a wide range of shapes, colors, and variations. Hydrangeas can be broadly divided into three groups: Hydrangea macrophylla, Hydrangea quercifolia, and Hydrangea paniculata, though there are far too many variants to list them all.
Common names for hydrangea macrophylla include bigleaf, mophead, lacecap, and French hydrangeas. The big-leaf hydrangeas are among the most popular varieties. Depending on the pH of the soil, this group of hydrangeas can produce blue or pink flowers. Because it alters the amount of available aluminum for the plant to absorb, soil pH is to blame for changing the color of the flowers. Pink flowers grow in alkaline soils, while blue blooms grow in acidic soils (soil pH: 5 to 5.5). (soil pH: 6 or more).
The oakleaf hydrangea is also known as Hydrangea quercifolia. Oakleaf hydrangeas feature leaves that resemble an oak leaf and offer a stunning display of white flowers. In addition to offering a lovely flower display in the summer, oakleaf hydrangeas also provide interest to the landscape with their colorful fall foliage, interesting leaf texture, and appealing bark. Suggested kinds of oakleaf hydrangeas include “Snow Queen,” “Snowflake,” and “Harmony.”
PeeGee hydrangeas are a subgroup of Hydrangea paniculata. PeeGee hydrangeas can reach heights of 10 to 25 feet. PeeGee hydrangeas have panicle-shaped blooms rather than ball-shaped ones. As the petals ripen towards the fall, the blooms are also renowned for taking on a pink hue.
The process of growing hydrangeas is not too difficult. Depending on the cultivar, hydrangeas can reach heights of 4 to 12 feet. The hydrangea’s growth pace is fairly rapid. Choose a spot with well-drained soils when choosing where to plant hydrangeas. In soils with a lot of organic matter, hydrangeas thrive. A site with early sun and afternoon shade is ideal for hydrangeas. They shouldn’t be cultivated in arid, hot climates. Many people consider buying and planting hydrangeas when they see them in bloom in the summer, but the optimum times to plant are spring and fall.
Small amounts of fertilizer applied periodically throughout the growing season are beneficial to hydrangeas. Hydrangeas respond well to a complete fertilizer, such as 10-10-10, applied at a rate of 2 cups per 100 square feet in March, May, and July. When fertilizing, it is not required to remove the mulch; however, watering soon after application will help the fertilizer dissolve and go into the soil.

In North Carolina, how are hydrangeas cared for?
Although hydrangeas are advertised as being able to tolerate both full sun and part shade, it is better to grow them in part shade here in the south. They will specifically thrive when planted in a location with dappled shade, morning sun, and afternoon shade. They require nutrient-rich, well-drained soils.
How far north can hydrangeas be grown?
Not all varieties of oakleaf hydrangea do well in USDA zone 5, despite the fact that it is possible to grow them there. In that region, “Snow Queen,” which is cold-hardier than most plants, creates thick flower clusters. When the plant is young and not yet well-established, other kinds could require winter protection, such as a burlap wrap. Even if spring flower buds are damaged by frost, the shrub can still be appreciated because it has lovely foliage and bark.
What is the ideal location to plant hydrangeas?
Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.
When should I plant hydrangeas?
The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.
Locations to plant hydrangeas
The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.
hydrangea-friendly soil
The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.
Methods for planting hydrangeas
Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.
The best way to grow hydrangeas
Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:
- Close to your hydrangea plant, make a tiny trench.
- Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
- Where the branch meets the trench soil, make scuff marks on the bark.
- After the trench is filled, cover it with a paver, brick, or stone.
- The branch can be transplanted to a different area once it has established its own root system over time.
Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.
Do hydrangeas prefer shade or direct sunlight?
It’s no surprise that hydrangeas have grown to be so well-liked among gardeners given their profusion of blossoms and remarkable adaptability. There is a hydrangea for almost every garden because there are so many different types. They are certain to provide you happiness year after year if you give them a sunny place with well-draining soil. Will hydrangeas flourish in the shadow, though?
Full sun (more than 6 hours of direct sunlight) to part sun is ideal for hydrangea growth (4-6 hours sun). All hydrangeas can tolerate some shade, but the timing and nature of the shade should be taken into account. As long as they receive some early sun, they can spend the warmest part of the day in complete shade. In sweltering conditions, this is especially true. They don’t flower as frequently, though, and their stems tend to be weaker and floppier if they don’t get enough sun.
Don’t let a little shadow ruin your plans for a hydrangea garden. A list of hydrangeas that can tolerate shadow better than others has been assembled.
Which side of the house should hydrangeas be planted on?
Bushes called hydrangeas bear white, pink, or blue blooms. These are small flowers that grow in voluminous bloom clusters. These bushes will typically reach a height of four to six feet and bear flowers that can range in length from six to eighteen inches. These shrubs thrive best in damp soil and are extremely cold hardy. These shrubs prefer some shade and cannot stand full sun or complete darkness. H. anomala, a climbing variation of hydrangeas, is also available. This type can either be let to grow along the side of a structure or planted on a trellis on the north side of the house. It has the capacity to grow as tall as 80 feet. Hydrangeas do well when planted close to small evergreens or woody shrubs because they also do well in woodland regions.

Can hydrangeas be planted in the lawn?
You need to seek for areas where hydrangeas can flourish when deciding where to put them in your front-of-house landscaping. Hydrangeas like full sun if you reside in a northern region. In contrast, hydrangeas thrive in Southern climates where they like early full sun followed by afternoon shade or partial sun. According to The Old Farmer’s Almanac, the region should also have fertile, moisture-rich soil that drains properly.
Make sure there is enough room for the hydrangeas to spread and grow when selecting a spot. They can grow up to 15 feet tall and between 3 and 10 feet broad, depending on the kind. So you should watch out that a mature plant doesn’t take over your front-of-house landscaping.
The function of the plant is another factor to take into account when using hydrangeas into front yard landscaping. In front of a tall porch, do you want it to act as a natural screen? Will they serve as focal pieces on the porch steps or as flower bed bookends? They may serve as a kind of inorganic fence separating the front yard from the side yard or the backyard. Your choice of the finest location to plant your hydrangeas will be influenced by the purpose.
