In our Complete Hydrangea Guide, you can learn even more about caring for hydrangeas.
Why are oakleaf hydrangeas so straightforward? They are not particular! In comparison to other hydrangeas, oakleaf hydrangeas can withstand cooler temperatures, greater sunlight, drought, and pests and diseases, and they do better in sandy soil.

Enjoy the beauty of snowflakes in the middle of summer with the snowflake hydrangea. The snowflake variety of oakleaf hydrangeas blooms for the longest period of time. Additionally, it truly stands out because to its double flowers! It’s understandable why this hydrangea is one of the most well-liked varieties.
June till the end of summer. Snowflake-like, stark white, double flower blossoms that first turn pink then brown.
- rapid growth
- doubling up
- Stunning maroon foliage in the fall.
Red-leafed hydrangea little but mighty This small hydrangea, which only reaches a height of 4′, produces nine flower blooms at once. And the duration of those flowers is up to two months. Think again if you believe you lack space for a hydrangea. Even a tiny garden will suit Ruby Slippers!
In the early to mid-summer. massive white flowers that quickly become pink in color
- Compact
- enduring pink flowers
- thrives in hot, dry conditions with inadequate soil.
- striking red fall foliage that persists till the beginning of winter
After it has grown, fertilize your oakleaf hydrangea every spring with Espoma’s Plant-tone.
Which hydrangea develops most quickly?
One of the simplest and quickest-growing hydrangeas is limelight! This blossoming plant, a hydrangea, is quite gorgeous! It’s the only one I have that survived our exceptionally cold winter in Georgia without suffering any damage. The only other hydrangeas I have have a few blooms and mostly foliage (except my Endless Summer ). Why, in my opinion, should you plant this hydrangea in your garden (zone 3-8).
The beautiful lime green petals of the Hydrangea paniculata ‘Limelight’ bloom from May till the end of the season. In the fall, the petals become pink. On the one above, you can barely make out a tiny touch of pink.
This limelight is thriving despite our chilly winter since limelights bloom on fresh wood in the summer. They should be pruned in the late fall, early winter, or early spring. But this one didn’t seem to mind that I never got around to trimming it.
It is hardy to Zone 3/4 and known for its huge, dense, tall, cone-shaped panicles. They are trainable into a tree shape and can reach heights of 8 to 10 feet!
The image above shows how they seem just before they begin to blossom. The blooms get enormous as they mature and fill out!
As you can see in the picture up top, I planted this shrub in the spring of 2012. The pot is now empty. Rhododendron that has passed away is the shrub with the white blossoms. Fortunately, the hydrangea and rhody couldn’t have shared space!
This year, that small shrub is the same one. Limelight is expanding quickly! This one does receive a lot of morning sunlight, but the barn provides midday shade.
Limelight is a really stunning hydrangea. I wholeheartedly endorse it, especially if you’ve had trouble cultivating other hydrangea kinds!

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.
They are hardy
The species of hydrangea most tolerant of freezing temperatures is the panicle. They are dependable shrubs or tiny trees that thrive with little effort. Their sturdy, reddish-brown branches range from being straight to arching and occasionally bow from the weight of the enormous blossoms. Although something closer to 6 or 8 feet tall and wide is more typical, something up to 15 feet tall and wide is possible. Panicle hydrangeas are typically too large for small gardens, but anybody may enjoy them with careful pruning or by picking a tiny variety like ‘Dharuma’ or Quick FireTM.
Pruning doesn’t affect bloom
Panicle hydrangeas don’t mind being clipped, unlike bigleaf hydrangeas (H. macrophylla cvs., Zones 69). Typically in early spring, I advise trimming the plants back by about half of their height before the leaves appear, though this is optional if you have space for a larger plant. Due to space limitations in the trial beds, we had to start trimming, but the better habits and results we saw afterward encouraged us to keep doing it. The size of the hydrangeas with annual pruning is depicted in the chart below. Contrary to many bigleaf varieties, panicle hydrangeas bloom on new wood, thus trimming won’t stop them from producing blooms and might even make them bigger. Annual trimming, in contrast to some accounts, did not promote long, feeble stems that were unable to sustain the weighty blossoms. All the cultivars, with the exception of “Dolly,” were robust enough to support their blossoms.
Flower type and size vary
Panicle hydrangeas produce a mixture of beautiful, sterile florets and frothy, fertile florets in their flowers. The showy florets, which vary in size and number depending on the cultivar, create the protracted bloom show, which is accentuated by a transformation from white to various pink tones. Unsurprisingly, the breeding trend has been to enhance the pink hue of the wilting blooms. I employ the words “To distinguish between the two floral varieties of panicle hydrangea, use the terms lacy and “mop.” In contrast, Lacy describes an open panicle with showy florets scattered throughout the fertile flowers “Mop is a sign of an excess of colorful florets with fertile florets buried beneath.
Watch the pHbut don’t worry about deer
I discovered that the alkaline nature of our soils at the Chicago Botanic Garden, particularly in hot, dry weather, may contribute to panicle hydrangea foliar chlorosis. Consistent watering will guarantee healthier foliage and more robust bloom output in hot conditions. Panicle hydrangeas are resilient to urban environments and rarely encounter pests or illnesses. While some cultivars are frequently praised for their mildew tolerance, none of our plants ever developed powdery mildew. Deer also favor bigleaf hydrangeas, but they usually show less interest in panicle varieties.
They have some winter interest
I’m not crazy about going into detail about a plant’s winter characteristics, but I disagree with detractors who claim that panicle hydrangea lacks any winter appeal. When rimmed with frost or covered in snow, the faded brown blossoms add some color and structural interest. I prefer to leave them on till spring because I’m a lazy gardener at heart and I’ll be pruning the branches anyway. When the crispy panicles break off and roll across the garden like tiny tumbleweeds, it’s entertaining.
Is it simple to grow Limelight hydrangeas?
Though I’ve always lived in a historic area and only had a little plot of lawn, I love to have freshly cut flowers in my home. My quest for plants with a big impact in a small space has lead me to find treasures that grow an abundance of flowers—enough to cut and yet have extra in your garden. The Limelight Hydrangea is one of my garden’s most treasured plants.
Here in Zone 7, the Limelight Hydrangea doesn’t bloom until late June or early July, unlike the gorgeous Oakleaf and Antebellum hydrangeas, which both bloom in large white clusters from mid-May to late June. Therefore, if you adore hydrangeas as much as I do, the Limelight maintains your garden looking lovely all summer long and until the first cold.
The Limelight hydrangea is one of the quickest-growing varieties and is thought to be one of the easiest to grow. The ones I grew three years ago have grown to be almost six feet tall. They thrive in many types of illumination. You can cut as many blooms as you like because they generate so much. Furthermore, some of the clusters are so enormous that they nearly seem ridiculous.
They begin as a bright, pale green and gradually transition from white to light green. Decrease colors begin to blush as the temperature begins to fall, adding another another statement. After turning green, they are by far the simplest hydrangeas to dry; simply fill your vase with them and leave them. They will dry and look precisely the same as they did when they were brand-new once they have absorbed all the water offered. It’s amazing how simple this is and how beautiful they are. Before the first freeze, my kids and I will just take off all the flowers since they will turn brown on a night below 32 degrees. We just have two or three-year-old bushes, but we come in with enough flowers to decorate multiple homes. And throughout the summer, many blooms were cut from these bushes.
No matter how little your garden may be, by adding a few Knock Out roses—which also produce a high mass of flowers and grow incredibly quickly—you can have fresh flowers right from your garden all summer long!
Just remember that your only objective if you plant any hydrangeas in the spring is to keep them alive until the following spring. This first year, give them lots of water. This summer, they may or may not appear depressing. However, they grow back robust and aren’t quite as delicate following that first winter in your garden.
Most neighborhood nurseries and many larger chain supply stores provide limelight hydrangeas. Happy sowing and harvesting!
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.
