Although oakleaf hydrangeas can be grown from cuttings of established shrubs, Zawojski notes that you can usually find the plants at your neighbourhood garden centre in three-gallon pots, ready to be planted directly into your garden. During the spring, early summer, or early to late fall, he advises planting. He advises against planting bushes in months with extreme weather, such as January or February or the months of July and August.
When should hydrangeas be planted?
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.
Is September a good time to grow oak leaf hydrangea?
In the late fall or early spring, when the plant is dormant and won’t be harmed by hot temperatures, plant fresh oakleaf hydrangea. The optimal growing conditions for this shrub are full sun or partial shade, rich, slightly acidic soil, and good drainage.
How soon can I move my oakleaf hydrangeas?
If the ground is not frozen, late fall or late winter are the best times to transplant your Oakleaf hydrangea. As oakleaf plants like well-drained soil, avoid transplanting them in heavy soil. If the soil in your plant’s new habitat is heavy, thoroughly amend it with organic matter. Oakleaf hydrangeas are susceptible to winter wind damage; for optimum results, select a sheltered setting. When lifting and moving your plant, remember that the Oakleaf Hydrangea and its root ball will be very heavy. If necessary, ask a buddy or two for assistance. The task will be simplified by using a wheelbarrow, stone boat, or sled. I’ve made my own sleds out of strong gauge plastic or tarps. You can think about bundling the canes loosely and wrapping them in burlap, a tarp, an old sheet, blanket, or rug to protect them from damage while digging and transferring. Insert your shovel around 1-11/2 feet away from the plant’s base to dig up your oakleaf. With the shovel, make a circular cut through the ground, elevating the blade to free as much of the root ball as you can. Lift the plant by working the shovel under the root ball. Your hydrangea should be moved and replanted as soon as you can to prevent root rot from desiccation. Create a new hole that is roughly the same depth and width as the root ball. Once your hydrangea is in its new location, fill in the spaces around it with as much soil as is necessary. To settle the dirt and hydrate the roots, deeply water your plant. Since the plant is dormant, you most likely won’t need to water it again over the winter, but frequently checking for moisture would help to prevent the rootball from drying out. Until the roots have a chance to take hold, ensure the soil around the transplanted hydrangea remains moist (but not damp or soggy) in the spring. Over the transplanted Oakleaf’s root zone, spread a 3″ to 4″ layer of mulch to provide it with additional winter protection. To allow for airflow, leave a space of 2 to 3 inches around the stems. I have successfully used this technique to relocate hydrangeas, some of which were so enormous that a winch line was required to lift them from their previous place and ramp them onto a truck. While I always strive to dig dormant Hydrangeas without damaging many roots, I haven’t found it necessary to prune them after they’ve been moved.
Are oakleaf hydrangeas sun or shade lovers?
It’s like asking me which of my children is my favourite to ask me which plant is my favourite! It’s a hard topic to answer, but since I don’t have to worry about hurting anyone’s delicate little egos, I’d have to say the oakleaf hydrangea is one of my favourite plants (Hydrangea quercifolia). The reason is because this plant is interesting in all four seasons. That is good since it allows me to save time, effort, and money. It rewards me in the spring, summer, fall, and winter once it has established.
The natural Hydrangea quercifolia grows to a height of six to eight feet, occasionally reaching a maximum of ten to twelve feet. The Northern Red Oak, from which it derives its popular name, may be seen in the shape of the enormous, dark green leaves, which also have silvery undersides. It is hardy in zones 5 through 9.
Cone-shaped flowers can reach a length of a foot. Initially white in colour, the blossoms eventually take on a pink tinge before turning crimson as the seasons change. Single or double florets are both possible.
Although the spring and summer are lovely and lush, I eagerly await the warm days and cool nights of October and November, when the flowers turn red and the foliage takes on a variety of colours of yellow, orange, red, brown, and burgundy. The leaves last a long time in protected areas before falling to show an uneven branching structure of exfoliating bark in hues of cinnamon. It looks stunning against a white blanket of snow.
Where the summers are hot, oakleaf hydrangeas bloom best, though they like some afternoon shade. It can be planted in full sun if you live in its more northern range. You’ll receive the most stunning fall colour and more blooms per square foot of sun exposure.
Unlike its mophead relatives, this shrub can survive drier soil, but it cannot endure damp feet. Plant it on soil that is acidic, moist, well-drained, and has been improved with compost or other organic material. It can be used as a specimen feature in the landscape or as a mass planting in shaded wooded regions.
Despite the rarity of the need for trimming, make sure to do it after blooming and before August. Late summer and early fall are when flower buds for the following year are formed. Old flowers can be deadheaded at any time by simply cutting them off. I prefer to keep the flowers on the shrub through the winter.
Before August, you can cut longer stems if you’re cutting blossoms for floral arrangements. After that, only trim short stems to avoid losing blossoms for the following season.
Oakleaf hydrangeas are comparatively free of pests and diseases. Another benefit, in my opinion, is that plants will continue to appear and function at their best throughout the year without the usage of any chemicals (always a last resort in my book).
Most people undoubtedly know about the double flowering variety called “Snowflake.” Up to a foot long, its creamy white blossoms are present.
“Little Honey” features springtime foliage that is golden, which later turns to chartreuse, green, and stunning burgundy red in the fall.
Oakleaf hydrangeas are a mainstay in my gardens, for sure. They are gorgeous all year round with stunning foliage, lovely flowers, and intriguing bark and are hardy in many regions of the country. They blossom in the shade, are resistant to pests and diseases, and are quite carefree. What more could we expect of a plant like this for our landscapes and gardens?
Can I currently plant hydrangeas?
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.
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 fertiliser, 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 fertiliser 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.
