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.
In April, may I plant hydrangeas?
Choose Perfect. Big? Little? Low-maintenance? perhaps altering color? There are SO many gorgeous varieties of hydrangeas available. Find the ideal candidate here. While most hydrangeas prefer shade in the afternoon and sun in the morning, several varieties can tolerate full light.
Select Mild. 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.
Water source. Water the hydrangea until a puddle appears immediately after planting. Up until it becomes established, water your hydrangea twice a week. When you notice that the plant’s leaves or blooms are fading, water it deeply once a week.
What about Holly? To maintain the soil acidic while producing blue hydrangeas, fertilize with Holly-tone. Alternatively, choose Flower-tone. Feed your hydrangeas two to three times each week from spring till fall for the greatest results.
Welcome your brand-new hydrangeas! While they are attractive in the yard, cut flowers inside will enhance their beauty even more.
When should you plant hydrangeas?
The majority of hydrangeas can be planted in the early spring or early fall; according on your region, choose the best planting season. According to the advice on the plant tag, space your plants properly. When the top inch of soil is dry, check the soil monthly and water. To help your watering efforts last longer and avoid weeds, spread 3 inches of mulch on the ground.
Can hydrangeas be planted in the late spring?
Many homeowners are feeling tempted to embark on fresh landscaping tasks as the warm spring days get underway, including planting vibrant hydrangea plants to liven up their yards.
Late spring and early summer are ideal times to plant and be ready for a summer bloom that lasts through a moderate Florida fall because the brightly colored bushes need full light in the morning with some afternoon shade.
The fact that hydrangeas are relatively simple to grow and can handle a variety of soil types makes them the ideal flower for novice gardeners. Hydrangeas come in a variety of hues, styles, and sizes, from crystal-clear blues and icy whites to vivid pinks and lavenders.
Garden hydrangeas come in a wide range of variations, which explains why they grow in a variety of temperatures. The Bigleaf, or French, hydrangea is the most prevalent kind in the north Florida region, particularly the well-liked Mophead and Lacecap variants.
Reblooming hybrids that bloom in the summer and occasionally produce additional flowers throughout the year are the blue Mophead, “Endless Summer,” and the pink to blue Lacecap, “Twist and Shout. Hydrangeas are a great option if you’re searching for a plant to offer a hint of color late into the fall season when others have gone dormant.
It’s time to plant once you’ve determined which variety of hydrangea is best for your yard. Giving hydrangeas adequate room to grow is crucial when planting them in a garden area. Dig the holes 2 to 3 times as wide and 3 to 10 feet apart, as deep as the root ball. After placing the plant in the hole and adding soil up to halfway, water it. After the water has subsided, add soil to the empty space in the hole. By doing this, you can prevent the soil from drying up and lessen the possibility of withering leaves.
If you wait to plant hydrangeas until early summer, they will require a lot of water in the first several months after planting. The secret to cultivating the majority of hydrangea cultivars is rich, moist soil. Your soil’s fertility will also determine if you need to fertilize the plant. It’s better to feed the plants once a year in the late winter or early spring if your soil is light or sandy. Still, you must be careful not to overfertilize hydrangeas because doing so can promote leaf growth and prevent blooming.
It is advisable to avoid pruning after July since hydrangea flower buds sprout in the late summer and blossom in the next season. This gives enough time for both regrowth and flowering this year. Beyond removing dead wood, most hydrangea plants don’t require much pruning. In the fall or early spring, if you chop off more than simply dead branches, you can also be destroying the buds for the upcoming season. Sometimes hydrangeas may have been planted in the wrong spot or may have grown larger than expected. When this occurs, only a third to a half of each major stem should be cut off.
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.
Can I still plant hydrangeas?
VERY IMPORTANT: Pick a spot where your hydrangea will be able to grow to its full size without being pruned. For hydrangeas of average size, aim for a height of at least 4 ft. X 4 ft. It is nearly impossible to keep hydrangeas clipped to a size that is smaller than what they ultimately want to grow.
Plant in a soil that drains properly! Add roughage, such pine bark mulch, to heavy soil (make sure it’s ground BARK, not ground WOOD).
Avoid planting seeds too deeply. Plant at the same depth at which the hydrangea was potted.
When a hydrangea has lost all of its leaves and gone dormant, transplant it (late fall or winter).
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 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!
Can I put a hydrangea in a pot outside?
“For Mother’s Day, my daughter handed me a lovely hydrangea. It has done so wonderfully that I’m curious if I should plant it outside or keep it within as a houseplant.”
Hydrangeas with foil encircling the pot, whether they were a gift or something you bought yourself, frequently differ from those bought at a nursery. The foil-wrapped hydrangea is often grown for a single, grand performance. The plant has been specifically fed to produce a lot of huge blooms quickly, frequently at the price of the plant’s long-term health.
The hydrangeas selected for this project are exclusively grown in greenhouses and might not be winter hardy where they are purchased.
If your locale isn’t warm enough to cultivate hydrangeas outdoors, you might wonder if you can grow them indoors as a houseplant.
A. There are a variety of reasons why growing hydrangeas inside in a home environment is not particularly successful. When hydrangeas may experience a period of dormancy brought on by chilly weather, they thrive. Hydrangeas rarely blossom indoors, attract insects, and lose their leaves unless they are in a greenhouse. They frequently dry out too rapidly and wilt, which makes them weaker.
However, some gift/florist-type hydrangeas may be grown extremely well in the landscape, as you can see from the images below.
Although growing hydrangeas indoors is not the optimal answer, it is conceivable if one lives in an apartment or in an area where they cannot survive:
1) Put the hydrangea in the coolest part of your house; ideally, an unheated room.
2) Position it close to a window so that it receives the most light possible.
The third and most crucial tip is to not overwater the plant by letting it sit in water or by watering it too frequently. It’s preferable to keep it dry during the winter, but it shouldn’t ever get too dry that it wilts.
Whenever possible, it is ideal to plant the potted hydrangea outside. It should only be planted outside in the early to mid-summer because it needs time to get used to the weather before winter.
In conclusion, unless it may be planted in the garden, foil-wrapped hydrangeas are best employed as a temporary plant in a person’s home.
