One of the most well-liked shrubs for landscaping is the hydrangea. These lovely, flowering shrubs are noted for their ability to produce ball-shaped clusters of tiny flowers in a range of vivid hues, including blue, purple, pink, and white. They are frequently adored by Tulsa gardeners for their profuse, colorful flowers that seem to cover the entire garden.
But hydrangeas may find life challenging in Oklahoma due to the state’s frequently unpredictable and occasionally harsh weather. To withstand the extreme heat of Oklahoma, they frequently require a lot of care. Which of these magnificent shrub kinds thrives in Oklahoma, then?
The Endless Summer hydrangea is a reblooming hydrangea that can bloom every few weeks in the summer and fall. It can bloom on both fresh and old wood, and it can withstand Oklahoma’s cold weather better than other types. These thrive in a spot that receives morning sun and afternoon shade that is somewhat shaded. Like other types, these hydrangeas require rich, moist soil that drains well. Although they require a lot of water, they do not thrive in muddy or perpetually moist environments.
One of the hardiest hydrangeas with some of the longest blooms is the Annabelle variety.
These lovely shrubs for the landscape bloom till they are brilliant white before changing back to light green. In Oklahoma, annabels typically bloom from early June through September. This cultivar is reputed to be extremely disease resistant and more drought tolerant than others.
A hydrangea that is reputed to be simpler to grow is the oak leaf variety. The Oak Leaf has distinctive cone-shaped clusters of white flowers in contrast to the ball-shaped or “mop head flower type, as well as oak-like leaves that turn a stunning reddish-purple in the fall.
What is the ideal location for hydrangea planting?
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.
Do hydrangeas grow naturally in Oklahoma?
In Oklahoma, hydrangeas (Hydrangea macrophylla) are a common shrub choice for landscaping. In ideal circumstances, they can reach 6 feet in height and 10 feet in width. Depending on the species, hydrangeas produce enormous globe-shaped flower heads made up of thousands of smaller pink, blue, green, purple, or white flowers. Since they persist a long time, the blooms are frequently used in fresh or dried cut flower arrangements. The most popular mop head hydrangea types are not native to Oklahoma and require special attention to survive the summer’s extreme heat.
Choose a spot for your hydrangea shrubs that will shield them from the hottest afternoon sun. Best sun exposure is in the morning till noon. Planting can be done by placing it on the east or north side of a structure or shade tree. If the hydrangea bushes are already established, you will need to move them to a new place or provide shade for protection. Hydrangeas planted in full sun may struggle to survive, while those planted in full shade will grow spindly and produce fewer blooms.

Take a look at the location where the hydrangeas are grown. While they do not thrive in soggy or wet soil, hydrangeas do best in damp soil. Dig a trench with a shovel if the area is poorly draining to prevent water from pooling around the plants.
Around the hydrangea plants’ roots, cover the planting area with a 2-inch layer of compost. Spread the compost evenly across the soil surface using a rake to avoid upsetting the plants’ thin roots.
To keep the hydrangeas’ root system moist and shield it from weed growth, add a 1-inch layer of mulch around it. Rake out the mulch layer surrounding the bushes each spring, then add an additional inch of compost before putting new mulch.

To keep the hydrangea plants from withering in the late afternoon, water the soil around them as often as necessary. Apply water to the soil surrounding the roots when you water. Avoid misting the blooms or foliage with water. When the plant is wet, the likelihood of developing fungus and mildew infections rises.
If pruning is necessary, do it as soon as the blooming season is over. Because hydrangeas bloom on wood that was created the previous season, pruning hydrangeas late in the season might impair the production of blooms the following year. Dead wood must always be removed.

Use a fertilizer designated for hydrangeas, as indicated on the label. Pay close attention to the instructions on the package. The hydrangea plants’ ability to bloom can be hampered by excessive fertilization. Start fertilizing in April, and then follow the fertilizer’s label’s suggested schedule after that. Your final fertilizer treatment should be no later than September since there is no need to fertilize once the plants become dormant in the fall.
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. Additionally, panicle hydrangeas are the most resilient varieties.

When should 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.
Do hydrangeas grow in numbers?
When clipping hydrangeas to propagate the plant, when you cut and where you cut are two important considerations. The optimal period is when new stems first begin to stiffen, which is in late spring and early summer. New stems are prone to bending but are also easily snappable, and these cuttings have a strong growth tendency.
Cut a green, fragile branch that is 5 to 6 inches long and that is not in bloom. Make sure the cutting has at least three sets of leaf nodes—the points at which a leaf emerges from the branch—but only cut just below a leaf node. The bottom two leaf nodes’ lower leaves should be removed. Reduce the biggest leaves by around 50% in size as well.
The procedure can be sped up but is not required by dipping the cutting in rooting hormone. Place it with one or two nodes submerged in wet vermiculite or sterile medium in a well-drained container.
Fill the pot with water, cover it with plastic, or set it inside a plastic container with a lid to create a mini-greenhouse or humidity dome. Plant them after four to six weeks, when a strong root system has developed. Keep your cuttings away from the sun’s harsh rays.
Does hydrangea regrowth occur annually?
Hydrangeas will indeed reappear each year if they do not perish during the winter. Though not all gift hydrangeas are bred to grow especially winter-hardy. Thus, hydraneas occasionally do not endure the winter. However, most hydrangeas will reappear each year.
