Shrubs including boxwood, hollies, yews, mahonia, gardenia, and loropetalum look lovely planted in front of hydrangeas. Early color will come from azalea blossoms. Since the azalea flowers will have faded before your hydrangea blooms, you can choose your preferred blossom color.
During the winter, boxwoods and evergreen azalea species will provide some color. Depending on whether you want a formal or natural-looking landscape, boxwoods can be shaped or left in their natural state. These may also offer some wintertime protection from high winds.
Can you grow hydrangeas and lavender together?
Hydrangeas and lavender are quite different plants with very different requirements. The U.S. Department of Agriculture’s plant hardiness zones 4 through 8 are ideal for growing lavender (Lavendula spp. ), a drought-tolerant plant. For survival, lavender needs a lot of light and almost no fertilization. Conversely, hydrangeas (Hydrangrea spp.), which grow in USDA zones 3 through 8, need to be watered often and thrive in afternoon shade. These plants must be given separate parts of the garden that will suit their demands when planted together in one location so that both can flourish.
Find a spot in your garden that receives full sunlight in some areas and afternoon shade in others. Plan out two locations: one for the lavender in full sun and one for the hydrangeas in the region that receives afternoon shade. Do this in the spring, once all danger of frost has subsided.
To stop water and fertilizer for the hydrangeas from soaking into the soil around the lavender, create a row at least one foot wide between the two types of plants.
Apply a one-inch layer of sphagnum peat moss to the ground in both garden spots and work the moss into the soil with a garden rake or hoe.
Each plant’s root ball needs its own hole, which should only be big enough for it to fit within while not sinking any further into the ground than the container it is in.
As your hydrangeas get used to their new setting, water them two to three times each week. Feel the earth around the lavender before you water the hydrangeas. Water the surrounding soil as well if it has become dried out. Reduce the frequency of watering both plants gradually until the lavender receives an inch of water once every two weeks or fewer and the hydrangea receives an inch of water per week.
Is it possible to grow peonies next to hydrangeas?
Peonies and hydrangeas can make excellent planting partners because peonies bloom earlier in the year than hydrangeas. After they are finished, the plant will start to die back, allowing hydrangeas to take center stage.
Peonies prefer a protected location and do well in either full sun or light shade. Additionally, as long as the soil is free draining, they can tolerate most soil types.
Can hydrangeas be grown in groups?
Hydrangeas can tolerate full sun if they receive enough water. However, during the hottest afternoon hours, they are significantly more content in an area with shade.
Consider planting taller plants, such as small or medium-sized trees, to provide the shade that shrubs like around hydrangeas. Some dogwood tree cultivars may be the appropriate size to provide shade as hydrangea plant companions. They also add lovely bark, leaves, and blooms to the mix.
Low-growing plants make excellent hydrangea plant mates. Depending on your preferences, you can pair hydrangea with either perennials or annuals. Make sure the thing you chose enjoys or at least tolerates shade.
In front of the hydrangea, create a mass of the shade-tolerant blooms. The bell-shaped flowers of foxgloves (Digitalis purpurea) are arranged on tall stalks. Pansies (Viola wittrockiana), which come in a variety of hues, could also be effective. Choose heucherella instead. Particularly dark, exotic cultivars like “Twilight” blend very well with the green foliage of hydrangeas thanks to their foliage.
Can you grow hydrangeas and roses together?
Even though Knock Out roses are less susceptible to disease, they nevertheless require the same basic care as other rose varieties. Any plant that covers roses or demands complete shadow is an issue because roses thrive in direct sunlight. Additionally, they require space, so vigorous growth like wildflowers are not the best companion plants. Additionally, roses are sensitive to damp feet and don’t do well next to plants that require soil that retains moisture, even though they enjoy deep soaking in the summer.
Continue reading to find out which plants you shouldn’t place near Knock Out roses. That stated, whether you can grow a specific variety alongside roses will depend on your garden’s climate and plant species. If you wish to grow these plants, think about doing so in separate pots and on plant stands rather than near to your roses in the ground.
Hydrangeas
Hydrangeas aren’t always the greatest flowers to put next to roses, despite the fact that their luscious blues and purples often go well with roses. Because roses require wet soil and lots of shade to thrive, these papery blossoms are in opposition with what roses require.
Large trees and shrubs
Although they can give your landscape more depth, trees and bushes shouldn’t be placed too close to your Knock Out roses. They absorb nutrients, water, and light while also obstructing it. Think about establishing a small hedge next to your roses, such boxwood.
Fuchsias
With their striking hanging blossoms and drooping growth, fuchsias are unquestionably appealing. They can also be used to enhance rose cups. But they can’t grow with roses since they need a lot of shade and moisture, just like hydrangeas.
You’re off to a terrific start with a hardy variety like the Knock Out rose, despite the fact that roses have a reputation for being nearly impossible to please. Knock Out roses benefit from garden bedfellows that not only look fantastic but also attract beneficial insects and deter pests, even though they are not particularly spectacular. You have a wide selection of options for acceptable plants to keep next to your Knock Out roses, from creeping thyme to marigold.
How can I create a landscape using hydrangeas?
In wooded settings, shade-loving hydrangeas flourish; however, keep them away from trees as much as possible to prevent competition for water. Hostas, local plants, or bulbs that bloom in the spring before the trees leaf out can be used to create a landscape around them.
To make sure you have space for a hydrangea in the center and hostas surrounding the bush, measure the area you’ll be setting your shrub in. Hydrangeas can range in height from 4 to 15 feet, and their spreads can be very different depending on the type. Hostas, despite being significantly shorter, have broad spreads that can reach 5 feet in length.
Following the nursery’s recommendations, plant the hydrangea, making sure to place the shrub in the center of the planting area.
The number of hostas you require depends on the eventual spread of each hosta and that of the central shrub. Choose at least six hostas to complement the color and shape of your hydrangea’s blooms. Generally, place three or more vase-shaped hostas in front of shrubs or other vertical shapes. If you want to highlight a pink or purple-blooming hydrangea with three or four blue-leaved hostas, or four purple flowers with three or four gold-leaved hostas, think about the color of the hostas’ foliage. White-variegated hosta varieties go well with white-blooming hydrangeas.
In a circle around the hydrangea, plant the hostas at the depth and separation the nursery suggests. In order to accommodate the eventual spreads of both plants, allow space between the base of the hydrangea and the hostas. To give the ring a more natural appearance, gently stagger the plants inside.
To unify the entire bed, cover the hostas and hydrangeas with the same kind of mulch.
Can you plant peonies and lavender together?
Peony flowers, a traditional component of the perennial border, give a brilliant splash of color to the environment. By combining them with companion plants like perennials, flower bulbs, or even ornamental grasses, you may add accent elements to your borders that have a particular shape, texture, height, or color.
Peonies only bloom for about 7–10 days, which is not very long. They are categorized with a blooming time that ranges from Very Early to Very Late season, although they do not flower at the same time. Therefore, you can choose to plant a variety of varieties, from Very Early- to Very Late season bloomers, to fill your garden with continuously flowering peonies throughout the season.
Here is a plant combination in white and lavender to help you plan your late spring or early summer garden. It comprises three gorgeous peonies that will bloom one after the other: “Miss America” (Early Midseason), “Cheddar Charm,” and “Bowl of Cream” (Late Midseason).
For a longer show, they are interplanted with three outstanding Tall Bearded Irises with various flowering times: “Belgian Princess” (midseason), “Hold My Hand” (late midseason), and “Twilight Rapture” (Late Season).
A dwarf Delphinium called “Magic Fountain Lavender,” two architectural Lupines called “Manhattan Lights” and “Gallery Yellow,” and Meadow Rue’s dense, fluffy panicles of lavender are blended with all of them (Thalictrum aquilegifolium).
The majority of plants make wonderful fresh cut flowers that can be enjoyed at home!
How far apart should hydrangeas be planted?
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.
