Hydrangeas can be planted at any time, but spring and fall are the ideal seasons. They will require a lot of care to survive if you plant in the middle of the summer. Put and Grow. Once you’ve selected the right location (preferably one with soil that drains well), dig a hole that is twice as wide as the hydrangea’s container.
When is the best time 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.
Can hydrangeas be planted in a hot climate?
Old-fashioned and well-liked, hydrangeas are prized for their stunning foliage and magnificent, long-lasting blooms that come in a range of colors. Although it is well known that hydrangeas flourish in cool, damp shade, some varieties are more resistant to heat and drought than others. These magnificent plants can still be grown even in hotter, arid climates. For additional information about hydrangeas that tolerate heat, continue reading.
How far into the year may hydrangeas be planted?
Choose a time in late spring or early fall when the nights are cooler and there is little risk of frost. If you garden in an area where the ground freezes, put seeds at least six weeks before the first deadly frost of the fall. This allows plants to establish roots before the ground becomes really cold. To improve root insulation, place a 2-inch mulch layer around plants after planting.
Can I move a hydrangea in the midst of the summer?
Hydrangeas can also be transplanted in the spring or summer, barring particularly hot summer days or heat waves.
Please be aware that a hydrangea in bloom may lose its blooms due to transplant shock. Buds and leaves may also be impacted.
To minimize any negative impacts of the summer heat on your plant, perform the transplant in the morning whether it is in the spring or summer.
Try to move as much of the dirt around the root ball of the plant with it, and water your hydrangea deeply after transplanting to lessen the shock of the relocation.
So, if it’s necessary, you can transplant hydrangeas in the summer, but it’s much less stressful on the plant to do so in the fall or in the early spring.
Do hydrangeas 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 varieties of hydrangea that perform well 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!
How can the heat of the summer be avoided by hydrangeas?
Q. My front yard faces northwest and is primarily shaded. I grew a number of hydrangeas, and they thrive besides on extremely hot days. Their leaves and blossoms are burned by the direct sun from 4 to 6 p.m. I want to swap them out for something bushy with lovely summer color that can withstand just two hours of really hot, direct sunlight. What ought I to plant?
A. We frequently have heat waves that last several days and reach temperatures above 100 degrees. The hydrangeas and other plants that are already there, I assume, are happy with the exposure on the other days.
It is challenging to recommend replacement plants that fit your requirements, nevertheless. The exposure that is frequently present in this location is what worries me.
Heat-tolerant plants can’t grow there because of the shade. Though they might not grow big enough for you, you could try planting a few flower carpet roses. My recommendation is to make no changes. Instead, I would advise you to cover the hydrangeas with shade cloth to protect them from the heat. Many garden centers and home improvement stores sell shade cloth. Choose the one that offers the most shade from the variety of densities available. This is only a cover for now.
The plant(s) are surrounded by wooden stakes, which are then used to support the shade cloth as it is draped over the plant(s). For frost protection, this method is the same as that employed in the winter. When temperatures are expected to be over 95 degrees, the covering needs to be set up.
It shouldn’t be difficult to predict the hot weather if the weather forecast is published in the newspaper or carried on the evening news.
Q. I’ve found raspberry vines encroaching on my house’s side. How can I permanently get rid of them? I’ve read that vinegar can be used to kill weeds. Does this apply to raspberries?
A. Since vinegar only destroys the top growth and a small portion of the roots, it is not a viable approach for killing raspberries or blackberries. You’ll need a herbicide that translocates downward because raspberries have a strong root system.
Vinegar will work just as well as a hoe. The vines will sprout back in a short while. Any pesticide labelled “Brush Killer” would be sprayed on the raspberries.
The issue gets trickier if other plants are mixed together with the raspberries. Additionally, the pesticide will eliminate useful plants. Spraying is still allowed in the open space where just raspberry vines are present, but avoid spraying the area around the plants you want to maintain. To reduce the spray drift, I’d use a tank sprayer rather than a hose end sprayer. By pruning the berry vines to 6 to 8 inches in length and hand-applying the herbicide solution with a little paintbrush, you may get rid of the vines that are encroaching on the desired plants.
The procedure will need to be repeated as necessary. The issue probably won’t be resolved this year, in my opinion. The end of daylight saving time marks the end of the growing season.
Can hydrangeas withstand direct sunlight?
The majority of hydrangeas only like morning sun. The panicle hydrangea is the only variety of hydrangea that can remain in the sun all day. Although they can tolerate the sun, these also thrive in some shade. Plus, panicle hydrangeas are the hardiest hydrangeas.

Are hydrangeas sensitive to heat?
Wilt and Heat Heat can sometimes cause hydrangeas to wilt even when they have ample water. Plants can become stressed out by high summer temperatures over 86 degrees Fahrenheit. While hydrangeas benefit from sunlight, excessive amounts of direct sunlight can warm the soil, stress the plant, and even cause it to wilt.
Can I now start a hydrangea?
While containerized plants are readily available year-round, the best selection of hydrangeas in garden centers begins to appear in the middle of the summer when they are in bloom.
They are typically offered in 3 liter pots that are at least 30 cm tall in garden centers. Young cuttings of mail-order plants may be offered in 9 cm or 1 liter containers.
When to plant
As soon as you buy your shrubby hydrangea, plant it. Spring or autumn are the ideal seasons for planting. As long as the soil is not frozen, too wet, or overly dry in the summer, containerized plants can be planted all year (but you can water them well if you really want to plant them then).
Soil preparation
If cultivars are grown in acidic soil, their blue flowers will maintain that color (pH 4.5-5). See our guides on soil acidity and how to acidify your soil for additional details.
