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.
Which side of the house should hydrangeas be planted on?
The vintage Hydrangea macrophylla, with its shape resembling a pompom, is one of my favorite summer blooms. My mother had a bank of blue hydrangeas planted on the north side of the home, and I can recall being drawn there as a child. The enormous blooms were as big as my head, and they were such a clear, deep blue that they looked more at home in a velvet-lined jewelry box than in the garden.
If you adhere to a few basic rules, growing traditional hydrangeas is simple. The majority of types can withstand minimal winter temperatures between -10 and -20 degrees F since they are cold hardy to zone 5.
Although hydrangeas are typically thought of as plants for shadow gardens, too much shade might diminish the amount of blooms produced. They should ideally be placed in locations with mild shade to some sunlight. Even in full daylight, if you live in a cool area, you can grow them.
Because they are woodland plants, hydrangeas like soil that is continuously moist, well-drained, and high in humus. Mulch should be applied liberally to keep the roots cool and moist. Old-fashioned hydrangeas require very little pruning. In fact, shrubs that have been incorrectly clipped may not blossom at all. Traditional hydrangeas produce their flowers on old wood, or the growth from the previous year. Your shrub is so getting ready to bloom the following year in the late summer and early fall. By removing any dead wood and spent flower heads in the early spring, you may clean up the plant. Find out more about hydrangea pruning.
I fertilize my hydrangeas in my Mid-South garden twice using a slow release fertilizer throughout the summer, typically in June and then again in August. This can be done once, typically in June, in milder climates. Observe the instructions on the fertilizer box. Just keep in mind that too much nitrogen will cause an excess of beautiful leaves to replace blossoms.
Where to plant hydrangeas:
- A location with morning sun and afternoon shade is ideal. They’ll take more sun if you reside further north (possibly full sun all day).
- Think about the mature size and give it lots of room to expand.
- Pick a location with great drainage. If necessary, add compost to the soil.
- Plants won’t thrive if they are planted too close to a tree because of root competition and a lack of sunshine.
- Planting should not be done in open locations where strong winds could snap stems.
How to plant hydrangeas:
- By amending your soil with up to 15% organic matter and an all-purpose slow-release fertilizer, you may give your plant a good start (use half of what is recommended).
- Plant a little higher than you did while you were in the nursery container.
- In order to give the roots plenty of freedom to expand, the planting hole should be two to three times broader than the root ball.
- Before planting, gently untie the roots from their pots.
- Add the modified dirt back in and thoroughly water it.
- Planting in groups requires a minimum distance of 3 feet (more, if planting larger varieties).
Planting hydrangeas in pots:
- Put potting soil in a bag rather than garden dirt.
- Slow-release fertilizer should be added.
- For watering, leave 1 to 2 inches between the soil’s top and the pot’s rim.
- Make sure the pot includes space for the plant to grow and drainage holes.
Hydrangeas able to face east?
The inability to develop lawns in gardens that face east is a common complaint among novice gardeners.
Therefore, even though a nice sunny garden with lush green grass may not be achievable in your area, Japanese forest grass nevertheless allows you to create a beautiful spectacle.
Japanese forest grass is a low-maintenance decorative plant that grows slowly. The plant forms clumps and has flat, long blade-shaped leaves with an arching habit.
Gold-yellow leaves are offered by Hakonechloa macra. They have a pink hue around the margins as October approaches.
In full sunshine, this plant will not flourish. The plant will wither as a result of the sun fading the leaves. Because of this, you won’t find them thriving in gardens that face south.
They create an amazing carpet when planted closely together that surpasses any typical lawn.
Japanese forest grass prefers full shade and shady situations when it comes to light. It is therefore perfect for your garden, which faces east.
These gardens receive a brief amount of early sun before becoming cold and shaded the remainder of the day.
Maintain a damp, but not soggy, lawn. To keep moisture in place, you might add a mulch layer.
According to the University of Wisconsin, Japanese forest grass is hardy between USDA zones 4-6 depending on the cultivar.
Berberis (Barberry)
Sometimes, you could discover that the plants you choose don’t seem to be content in your garden. This is not a result of your lack of green fingers.
In full sun, some plants will not grow well. They choose places that receive little sunshine during the day and are shaded.
Is it a good idea to put hydrangeas in front of a house?
Hydrangeas (Hydrangea spp.) continue to be a well-liked addition to any home garden or landscape because of its enormous, snowball-shaped blooms. Hydrangeas, which grow well in USDA hardiness zones 3 through 9, add a wealth of color to front-of-house facades, front porches, and flower beds throughout most of the country from spring to October. Even better, hydrangeas don’t need a lot of upkeep after they are established in order to produce a lot of blooms.
Can hydrangeas be grown on the house’s north side?
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.
- No matter where in the nation you reside, the north side of your house receives little natural light.
- Hydrangeas do well when planted close to small evergreens or woody shrubs because they also do well in woodland regions.
Can hydrangeas be planted on the south side of the house?
Need some assistance getting your own hydrangeas to bloom more successfully? Hydrangea cultivation doesn’t have to be difficult. The most frequent questions about cultivating these garden favorites have answers here. In the Q&A below, we’ll explain how to take care of hydrangeas, how to encourage them to bloom, and where to plant them.
As seen: Depending on the pH of the soil, many H. macrophylla cultivars can produce blooms ranging in color from pink to deep blue (even on the same plant).
Often my hydrangeas just don’t bloom. Am I doing something wrong?
Look closely at where they are situated. In general, hydrangeas prefer some shade and require some sunlight. To block sunlight, nurseries in the South grow plants in pine or shade buildings. According to horticulture Michael Dirr, “for most hydrangeas, the farther north they are, the more sun they can endure.” “They can get by with just three hours of daylight down in the South.” While hydrangeas can thrive in full sun in the North as long as they receive sufficient of water and aren’t exposed to dry winter winds, they should be planted in the South in areas with morning light and afternoon shade.
Sun and temperature both pose problems, especially for mopheads who are prone to drooping from heat exhaustion. They flourish in the salty air and like a seaside environment where breezes alleviate the heat. Try another traditional favorite, the peegee hydrangea (H. paniculata ‘Grandiflora’), which can survive full sun exposure and high temperatures. On the other hand, if your yard receives insufficient sunlight, consider planting oakleaf hydrangea, which enjoys some shadow.
A late spring or early fall cold snap can also have an impact on bloom; bigleaf hydrangeas (H. macrophylla) are particularly susceptible because they flower on the growth from the previous year. Consider smooth hydrangea, which is native from New York to Florida and as far west as Arkansas, and peegee hydrangea, which is also the most drought tolerant, if unpredictable frosts are a concern where you live. H. arborescens is recognized as a reliable blooming in cold areas and is a well-liked native.
Can hydrangeas survive in the shade?
In dappled shade that is neither very sunny nor overly dark, wet, well-drained soil is excellent for hydrangeas. Avoid sites that face south, especially if the soil is quite dry. Grow the climbing hydrangea on a north-facing wall or in a highly shaded area. Hydrangea petiolaris subsp. anomala.
Does hydrangea like shade or the sun?
With the ideal balance of morning sun and afternoon shade, hydrangeas flourish. Even the sun-loving Hydrangea paniculata will thrive in some shade. Some hydrangea cultivars may survive complete shadow, though.
The oakleaf hydrangea, also known as hydrangea quercifolia, is a substantial species of hydrangea that may reach heights of up to eight feet. In a shade garden, this big bush makes a beautiful backdrop. The height will provide excellent midsummer seclusion. Oakleaf hydrangeas are summer bloomers with mostly white blooms, elegant oakleaf-shaped leaves, and lovely peeling bark.
Hydrangea anomala ssp. petiolaris is another choice for full shade. This climbing species, which has lacy, white blossoms in the summer, can reach a height of 50 feet if it is given adequate support. The foliage is a rich shade of green and would look wonderful growing up a tree trunk or covering the face of a building. It would also look lovely covering the roof of a garden shed.
Full shade cultivars require the same upkeep as partial shade. In the deeper shade, it will be especially crucial to keep the plants free of leaf litter and with excellent airflow. Water your plant once a week after it has become established. Keep a watch on the leaves, and if you notice any drooping, especially during the hot summer months, water them right away. The importance of this increases in hotter regions.
These leaves’ unique shape would be a lovely complement to Hosta leaves. The white blossoms would contrast nicely with the lighter hues of your shady blooms and provide some brilliant brightness to your shaded locations.
Shade Varieties
There are a few different hydrangea cultivars that thrive in the shade. Some types can even thrive in zones 3 (which doesn’t warm up until later in the spring), which is one of the coldest growing regions. Let’s examine some of the best shade selections!
Hydrangea quercifolia ‘Snow queen’
The movie “Snow queen” is stunning. The flowers are stunning, as they are with all hydrangeas. These rose blush-colored blossoms appear in the middle of summer. The foliage of this plant is my favorite component. The leaves begin the season in a very deep green, gradually changing to a deep reddish bronze color, and finally finishing in that shade, offering a stunning splash of color to your fall landscape.
Hydrangea quercifolia ‘Alice’
With a height ranging between 12 and 15 feet, this Oakleaf Hydrangea is one among the biggest. In the summer, this plant blooms with incredibly deep cream-colored flowers. A woodland garden would be a truly lovely place for “Alice.” This cultivar would look especially beautiful if it were grown as a bordering hedge.
Hydrangea arborescens ‘Annabelle’
‘Annabelle’ enjoys partial shade and has some of the largest flowers in the hydrangea family (12 inches wide!). These enormous blossoms can be supported all season long by the sturdy stalks. This shrub can grow up to five feet tall and five feet broad, so give it plenty of area to expand. These enormous, all-white blossoms bloom for a long time.
In a mass planting, as a specimen shrub, or as a foundation planting, “Annabelle” would look lovely. These bushes should still be included in your cutting garden. Imagine a bunch of flowers that large! Wow!
