Hydrangeas have huge bloom heads and exude an old-fashioned elegance. How to plant and take care of beautiful floral bushes is explained in our hydrangea growing guide. Additionally, learn the answers to frequently asked questions like “why aren’t my hydrangeas blossoming this year?”

About Hydrangeas

These elegant plants are simple to grow, withstand nearly any sort of soil, and produce an abundance of blossoms that are unmatched in the world of shrubs for their stunning flowers. Clear blue, vivid pink, frosty white, lavender, and rose blossoms sometimes grow on the same plant, enticing us with their colors.

From container gardens to shrub borders to group plantings, hydrangeas are great for a variety of garden locations. Breeders seem to give us more possibilities every year, and gardeners have countless expectations for bloom size and color. Varieties abound. Pay attention to the species listed below to get an idea of how your hydrangea will develop as some require different maintenance. The joys you experience will be enhanced when you know what to expect.

Enjoy this tribute to hydrangea beauty and read our guide below to discover how to grow hydrangeas.

Where to Plant Hydrangeas

The majority of hydrangeas like fertile, moisture-rich soils that drain well. Compost can help improve bad soil.
Hydrangeas typically prefer some sun. In an ideal world, they would receive full sun in the morning and then some afternoon shade to avoid the intense midday sun. The Bigleaf Hydrangea (H. macrophylla), with its huge, prone-to-wilting leaves, is a prime example of this. Some kinds can withstand more direct sunlight.
Depending on the kind, place hydrangeas anywhere between 3 and 10 feet apart. Plants should always be spaced according to their anticipated mature size!

When to Plant Hydrangeas

The optimum season to plant hydrangeas is in the fall, followed by spring. The cooler shoulder seasons are the ideal times to plant shrubs because they will have plenty of time to build a strong root system before the intense heat of summer or the bitter cold of winter.
In the early morning or late afternoon, plant the shrubs. The plant is less prone to experience heat stress from direct sunshine because it is typically cooler.

How to Plant Hydrangeas

Gently remove the hydrangea from its container and examine the root ball. Snip off any rotten or dead sections, and if the plant is very root-bound, pry the roots free.
Make a hole that is two to three times as big and as deep as the root ball. The top of the planting hole should be level with the base of the plant, which is where the stem joins the earth.
After placing the plant in the hole, add enough soil to fill it halfway. generously hydrate. Fill the remaining space in the hole with soil once the water has been absorbed.
once more, thoroughly rinse.

How to Grow Hydrangeas from Cuttings

Cuttings of hydrangeas can be easily grown. They easily take root, and the process is a wonderful teaching tool for propagation. This is how you do it:

Find a branch on a mature hydrangea that is fresh growth and has not flowered. In comparison to older growth, new growth will appear lighter in color, and the stem won’t be as firm.
Make a horizontal incision 4 to 5 inches down from the branch’s tip. Make sure your cutting has at least three to four pairs of leaves.
Trim the cutting’s lowest pair of leaves so that they are flush with the stem. If you can afford to remove more than one pair of leaves, do so. Roots develop more readily from these leaf nodes. But make sure to leave at least two pairs of leaves at the cutting’s tip.
Remove the tip half of any leaves that are still pretty large by cutting them in half. This keeps the leaves from slamming into the sides of the plastic bag you’ll later use to cover the cutting (to keep the humidity up).
(Optional) Sprinkle rooting hormone and a plant antifungal powder on the stem’s leafless area (both available at a local hardware or garden store). This will promote roots and deter decay.
Prepare a small pot and put moistened potting soil inside. The cutting should be planted in the ground, buried down to the first remaining pair of leaves. Lightly water the area surrounding the stem to close any air spaces.
Wrap a plastic bag loosely around the entire pot. To prevent the cutting’s leaves from rotting, make sure the bag is not touching them. The bag can be supported by chopsticks or other such objects to keep it off the leaves.
Put the pot in a warm location that is protected from the wind and sun.
Only rewater your cutting after the top layer of soil is dry after checking on it every few days to make sure it isn’t decaying. In a few weeks, hopefully, the cutting will start to root! If you feel resistance when you gently tug on the cutting, roots have grown.

Watering

Make sure hydrangeas get enough water for the first year or two after planting and throughout any droughts.
Over the course of the growing season, water at a rate of 1 inch per week. Three times a week of heavy watering is preferable to shallow watering. Root growth is promoted by this.
All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water.
If the soil is too dry, the leaves will wilt, and there won’t be enough moisture for the flowers to bloom.
To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose.
The best time to water hydrangeas is in the morning to protect them from disease and get them ready for the heat of the day.
Under your hydrangeas, spread organic mulch to help keep the soil cool and moist, gradually add nutrients, and enhance soil texture.

Fertilizing

You might not need to fertilize hydrangeas if your soil is rich. When fertilizer is applied in excess, blossoms are sacrificed in favor of green growth. A soil test is the most effective tool for determining your fertility requirements.

Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times.

Several mild fertilizer applications in March, May, and June are beneficial for bigleaf hydrangeas.
Two applications in April and June work best for oakleaf and panicle hydrangeas.
The only time smooth hydrangea plants require fertilizing is in the late winter.

Winter Protection

Cover plants with bark mulch, leaves, pine needles, or straw in the fall, at least 18 inches deep. If at all feasible, create cages out of chicken wire or snow fencing and cover the entire plant, including the tip, with the cages. (Avoid using maple leaves; they have a tendency to mat after becoming wet and may suffocate the plant.)

How to Prune a Hydrangea

Many of the queries from readers concern hydrangea trimming. It makes sense that it’s unclear because it relies on the hydrangea kind. Fortunately, identifying which type you have makes determining the best pruning strategy simple. Discover the fundamentals below, then read more about pruning different varieties of hydrangea here.

Pruning Common Hydrangeas

The Bigleaf cultivar of Hydrangea macrophylla is the most popular garden hydrangea shrub. (For more, see below.)

Hydrangeas with large leaves, such as Bigleaf (H. macrophylla), Oakleaf (H. quercifolia), Mountain (H. serrata), and Climbing (H. anomala subsp. petiolaris), are pruned AFTER the summer blooms have passed. On stems from the previous season, these kinds bloom (“old wood).

Avoid pruning after August 1 since flower buds actually grow in the late summer and bloom the next season.
Dead wood should only be removed in the fall or very early spring.
To stimulate branching and fullness, trim one or two of the oldest stems by cutting them all the way to the ground.
Pruning the stems all the way to the base is necessary if the plant is old, neglected, or injured. For the following season, you’ll lose the flowers, but you’ll also revive the plant for subsequent ones.
The huge Mopheads should not be deadheaded (faded flowers removed); instead, you should leave them over the winter and trim them back in the early spring (to the first healthy pair of buds). Deadheading Lacecaps is OK; simply trim down to the second set of leaves below the bloom head.
Avoid pruning unless it is absolutely required while growing H. macrophylla (and H. serrata) cultivars in Zones 4 and 5, and then only after blooming. If not, merely remove dead stems in the spring.

Pruning Other Hydrangeas

Hydrangeas called Panicle (H. paniculata) and Smooth (H. arborescens) are clipped BEFORE flower buds develop. On stems from the current season, these kinds blossom (“new wood).

When the plant is dormant in the late winter, prune. The plant will therefore grow new buds in the spring that will result in blossoms even if the winter kills the buds.
In general, avoid pruning to “shape the bush” and just remove dead branches.

How simple are hydrangeas to grow?

The hydrangea plant is adaptable and simple to grow. They have no preference as to where they are planted. All they require is well-drained soil, some water, and some summertime shade.

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 like shade or the sun?

The answer is both, of course! Partial sun or partial shade-loving plants require between three and six hours of direct sunlight each day. Plants that thrive in the sun need at least six hours of direct sunshine each day.

Simply examine a specific area of your garden every hour or so from dawn to sunset if you are unsure how much sun your yard receives. From there, note if the area is sunny or shaded. Garden centers now sell sunlight estimators, which are a wonderful choice if you’re pressed for time.

In fact, all hydrangea species may thrive in some shade. Some of these species, meanwhile, will actually prosper with a little more sun. The panicle hydrangea, or Hydrangea paniculata, is one cultivar in particular that enjoys full sun.

The pH of the soil can affect the color of your flowers in many hydrangeas, especially when it comes to managing that hue. But H. macrophylla and H. serrata are two species that don’t do well in full sun or deep shade.

How frequently do hydrangeas need to be watered?

To help maintain moisture when planting in a container outside, choose a light-colored ceramic pot. Dark colors heat up more quickly. Make sure a drainage hole is present! At least three times every week, the hydrangea needs to be thoroughly watered. Never simply water the plant in one spot; always water it all the way around the container. The pot’s bottom ought to leak water. Never leave it submerged in water because the roots will rot away.

How can I maintain healthy hydrangeas?

The queens of the shrub world are hydrangeas. Their gorgeous blossoms are vibrant, rather simple to grow, and continue throughout the summer and fall when most plants have finished blooming. These hardy perennials may have flowers that are of the same color: blue, pink, white, rose, or lavender. Hydrangeas come in a few different types, and with the right maintenance and trimming, you may have the best-looking bushes.

First of all, hydrangeas like rich in nutrients, permeable, and somewhat damp soils. Compost can be added to a planting area to improve it if it is deficient in nutrients. In the mornings in the southern and warmer regions, they can tolerate up to three hours of direct sunlight because they prefer partial shade. They may survive full sun further north, but it’s crucial to keep them well-watered. If the air is too dry, the leaves will begin to wilt.

They should be planted two to three times as broad and as deep as the root ball in zones 3 to 9. Plants should be placed 3 to 10 feet apart. Both the spring and the fall are suitable times to sow them. Sandy or arid soil needs to be fertilized, but most experts advise using about half the minimum amount because using more would only promote green growth and fewer flowers. You won’t need fertilizer if your soil is already rich.

A new plant should first be kept well-watered for the first few years of its existence and should only be encouraged to flourish. It is advisable to mulch or cover your plant with straw 18 inches deep later, in the fall. Larger plants can be covered with tomato cages, filling the cage with protection. It will be prepared for the coming spring and summer by doing this, as well as for the colder months.

Knowing how to prune your plant correctly is one of the most crucial aspects of hydrangea maintenance and maintaining gorgeous growth. First of all, you should be aware that hydrangea plants can be divided into two types. The first group is made up of flowering plants. Plants that bloom on old growth are the second category. Knowing which category your plant belongs to will help you decide how and where to prune it each year.

For all plants, you can encourage a broader growth by annually trimming one to two of the oldest stems back to the base. Although you won’t have flowers that year, this encourages branching and fullness for years to come. Trim all of the branches back to the base if the plant has been severely neglected. Before you have flowers, it can take a year or two of healing, but when you do, they’ll be plentiful and healthy. Never leave any dead wood uncut.

In group one, there are two kinds and numerous cultivars. Hydrangeas with panicles (H. paniculata) and smooth leaves (H. arborescens). Each year, both will produce new stems and bloom on them. Both are resilient to zone 3 and don’t need any additional attention. Smooth hydrangeas are referred to as “Snowballs,” whereas Panicle hydrangeas are distinguished by their cone-shaped flower heads. Always remove any dead wood in the fall or very early spring, and by deadheading the flowers later in the season, you can promote greater flower growth. To encourage the growth of new flowers, it is necessary to remove flowers that have wilted at the base.

It’s crucial to remember that you shouldn’t shape these shrubs with pruning. When the plant is dormant in late winter, just before bloom, these should be clipped. This promotes the new growth that the flowers will blossom on in the spring.

A little extra care should be given to group 2’s climbing hydrangeas, bigleaf hydrangeas, and oakleaf hydrangeas (H. quercifolia). The most popular variety of hydrangeas are bigleaf varieties, which come in two varieties: mophead and lacecap. It’s okay to deadhead lacecaps because they have dangling blooms that grow from a flat central bloom. Mopheads feature large, spherical flower blossoms that resemble snowballs. Until the next spring, when they can be pruned back to the first healthy buds, these blossoms should be left on the plant.

This generally applies to all group 2 hydrangea cultivars. This is because you don’t want to chop off the previous year’s growth because the flowers bloom on it. You can remove the old flowers once they begin to bud, trimming any extra back to the strong young buds. Once more, dead wood can be removed, and a few branches can be pruned to the ground to encourage fullness.

Did you realize that you have some degree of control over the color of your flowers? It is real! Start with a Bigleaf (Hydrangea macrophylla) variety if possible. The pH of your soil affects the color of its blossoms. To determine where to begin, check the pH of your soil. Pink flowers are produced by a higher pH, while blue flowers are produced by a lower pH. By incorporating peat moss or sulfur, you can reduce the pH of your soil. To increase pH, add limestone. Keep in mind that a pH of above 7.5 is too high and will stunt development.

The color changes take a few weeks to a few months to occur and are not immediate. It is advisable to wait until the plant has reached maturity before making significant modifications to the pH because immature plants (those under 2 years old) are still recovering from the shock of their first planting. All plants will eventually fade towards the conclusion of their flowering cycle, frequently turning pink or green. This is typical, and the plant will bloom in the proper hue once more the following year. Your ideal blue flowers may become pinkish if you see this, which could be caused by hard water. Use rainwater, and their blue hue should return.

In conclusion, hydrangeas are resilient plants that require little maintenance. When properly maintained, they are also extremely adaptable and breathtakingly attractive. To keep in mind are the following:

Plant first in nutrient-rich, wet soil.
Second, disregard the instructions for shaping and pruning your plant.
Third, to make the plant fuller, trim back a few branches each year.
Fourth, once the plant is established and healthy, modify the pH of the soil to determine the color of your bloom.

If you adhere to these fundamental guidelines, you’ll have lovely flowering bushes for many years to come.
