How To Grow Red Hydrangeas

If you only want faint red hydrangea flowers, try increasing the soil’s alkalinity and watching how dark the pink gets. It operates as follows: A pH scale from 0 to 14 is used to gauge the acidity of soil. A pH of 7 denotes a neutral soil. Any soil with a pH below 7 is acidic, whereas soil with a pH above 7 is alkaline.

A red hydrangea will it remain red?

If the color of your red hydrangeas begins to fade or take on a bluish or purple cast, the soil is usually too acidic.

The plants shouldn’t be absorbing metal from the soil for the blossoms to continue to be red. In general, less aluminum will be absorbed by the plant when the pH of the soil is greater. If you want to be certain, you can buy a soil testing kit from your neighborhood garden supply store to find out the precise pH level of the soil.

As an alternative, Plant Addicts advises applying a fertilizer with high quantities of phosphorus. This aids in lowering the amount of aluminum that reaches the plant, keeping the flowers red. If none of these is successful, your garden’s soil may be particularly high in aluminum. If this is the case, you might want to think about cultivating your red hydrangeas in sizable pots, as it is much simpler to manage all the environmental factors in this way.

under stress because of something in its environment. You can take action to address the issue if you can figure out what’s putting your plant under stress.

Stress causes the redness of hydrangea leaves. Extremely hot or cold temperatures are typically to blame for this. The plant develops anthocyanin pigments that defend it in various ways and aid in the extension of the leaf’s life when subjected to these extremes.

I’ll outline the most frequent causes of reddening hydrangea leaves and offer some suggestions for how to get them back to their lush, green splendor.

What is the key to hydrangea growth?

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:

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.

The Magical Ruby Red Hydrangea is the reddest hydrangea available and a fantastic selection for sections of your garden that receive some shade. This type repeats its flowering cycle from May to September, producing enormous mop-head blooms in a gorgeous rich, blazing pink-red color. The blossoms remain gorgeous for several more weeks after they fade to a delightful deep crimson after six weeks. It can be mass-planted in bigger beds and used alone in smaller beds for summer color on a compact bush that is 3 feet tall and wide. This exceptional hydrangea’s vivid red-orange fall foliage adds even more intrigue.

grows well under standard garden circumstances.

The Magical Ruby Red Hydrangea thrives in locations with early light and afternoon shade and is hardy to zone 5. This plant does not fare well in dry or consistently wet soil; its ideal soil is rich and moist yet well-drained. Alkaline and neutral soils will keep the red flower’s color, but some fertilizer will promote more flowering. It will be more purple in very acidic soils, but it will still be stunning and perpetually in bloom.

Nothing beats hydrangeas for summer blooming, and their long-lasting blossoms put on a spectacular display in semi-shaded areas of the garden when blooms are so scarce. But many gardeners are dissatisfied since their plants struggle to produce numerous flowerheads. It’s crucial to select high-quality garden kinds for good flowering, and the Magical Ruby Red Hydrangea is the best choice for continuous blooming from spring to the end of summer. This compact plant is perfect for mass planting in mild shade, as individual plants in smaller gardens, as well as in pots and planters. Its enormous heads of strong pink-red blooms keep coming every day. In addition to the foliage turning a deep crimson in the fall rather than the depressing yellow that is typical of most hydrangea bushes, the flowers eventually fade to a sophisticated wine-red.

The Magical Ruby Red Hydrangea develops into a multi-stem, compact shrub very quickly, with numerous stems emerging from the base. It spreads out into a broad, spreading form that completely fills the spaces in your beds as it gets to be around 3 feet tall and 3 or 4 feet wide. Even before the flowers appear, the huge, unusually dark-green leaves create a rich appearance. They completely encircle the plant, and strong new stems continue to emerge from the base. The huge, nearly spherical leaves have a firm texture, a sharply pointed tip, and a prominent serrated edge. They have an appealing venation, a glossy surface, and are slightly larger than 3 inches long and slightly narrower than 3 inches wide.

The blooms won’t take long to appear, and they continue to do so from May until September. Each stalk terminates in a flower bud that initially sprouts into a cluster of greenish-white blooms before eventually changing into the reddest hydrangea bloom ever made. The enormous, nearly 7-inch-wide flower heads are stuffed with over 85 big florets, each with four flat petals and a small, lighter-pink core. The florets remain attractive for about 6 weeks after that, turning a stunning deep burgundy that is just as lovely in its own right as the bright red they were. You will be mesmerized by the variety of colors, which span from green to white to pink to red to purple to red. It is true magic.

For summer color, plant the Magical Ruby Red Hydrangea in partially shaded settings. Its strong stems support the flowers effectively, and the springtime appearance of the dark green leaves is pleasing. Plant it in locations with morning light and afternoon shade, or on the north side of a building or wall. Due to its small size, it is also ideal for planter boxes and tubs, where the months of color are guaranteed to be pleasing. Use it to brighten up and improve that crucial area of your garden by using it in the foundation planting around your home. To maintain the color of your mixed beds throughout the summer, plant it near shrubs that bloom in the spring.

Because its blooms develop both at the tips of stems from the previous year and on new stems that emerge from the base over the summer, the Magical Ruby Red Hydrangea is perpetually in bloom. On older stalks are the earliest blooms, while on young stems are the latter blooms. As further trimming will eliminate prospective flower buds, the only pruning you need do is to remove any dead wood in the spring. This makes the plant both attractive and simple to care for. The spent flower heads don’t even need to be removed until spring because they look good all winter.

The Magical Ruby Red Hydrangea prefers a site with morning sun and afternoon shade. Both much shade and excessive sun might lead to dryness in the summer, which can limit later blooms. Since hydrangeas are not drought-tolerant, the soil should be rich and moist yet well-drained. Water hydrangeas frequently. This hydrangea retains its red color well in alkaline and neutral soils, but it may turn more purplish when grown in extremely acidic soil. Unless the soil is damp and poorly drained, pests and illnesses are typically not a problem. A fertilizer schedule will promote maximum blooming, strong foliage, and huge blossom heads, preferably using fertilizer formulated for pink hydrangeas or flowering shrubs.

Although the mop-head hydrangea, Hydrangea macrophylla, is a native of China and Japan, wild plants have sparsely colored, small blossoms for flowers. The first cultivars that were introduced to Europe and America were created by Chinese and Japanese gardeners. These only blossomed on side stems from old growth, but they had huge, vibrant flower heads. This required only one late-summer flowering. New, reblooming cultivars have been developed by plant breeders, and Peter Kolster, a breeder from Boskoop, the Netherlands, is responsible for one such project. He has been creating robust, repeat-blooming plants with stout stems and big, colorful flower heads.

In order to fertilize the blossoms on an older variety named “Glowing Alps,” which has purple-pink blooms, Kolster utilized pollen from one of his own plants (#06-099-01). When he saw his seedlings blooming two years later, he chose one with vibrant, pink-red blooms and gave it the name “Kolmaru.” He named it Ruby Red and included it in his Magical line of new plants. Plants Nouveau, a breeders’ agent, arranged for his plant to be copyrighted in America and distributed by Star Roses and Plants, a company that specializes in getting the best new plants to gardeners all across the nation.
