Hydrangeas have traditionally had a special place in the hearts and landscapes of garden enthusiasts, thanks to their large blooms of ever-changing vibrant hues.

You may enjoy hydrangeas’ wonderfully beautiful flowers for years to come with very little upkeep if you know when to plant them. Here’s a short rundown of the optimal times to plant each variety.

When Is the Best Time to Plant Hydrangeas?

Planting your hydrangeas at the proper Date and Time and in the right season will offer them the highest chance of success. Take a look at this list of the best times to plant.

Early in the morning or around dusk

Before taking your hydrangea from the container, try soaking it early in the morning or around sunset.

Hydrangeas like milder temperatures and perform poorly in hot weather, so don’t plant your lovely flower at any other Date and Time.

Season: Autumn or Spring

The optimum time to grow hydrangeas is in the fall. If you miss the autumn planting window, plant them in the early to mid-spring.

When you plant in the autumn, you’ll have around six weeks until the first frost. Before it’s time to blossom, you want your plant to become used to its new surroundings and develop a strong root system.

Plant more delicate hydrangea varieties, such as mophead hydrangea, in the spring or by early October at the latest. Before the winter weather arrives, allow your hydrangea time to grow its roots.

Planting Times That Aren’t Perfect

Date and Time

Planting hydrangeas in the scorching midday or afternoon sun is not recommended. You don’t want the blossoms to droop or the foliage to blister.

Calendar Year

Hydrangeas aren’t fussy plants, although they shouldn’t be planted in the summer. They can’t take much heat and will wilt if left in the sun for more than three to four hours.

Some individuals may plant most hardy hydrangeas all year if the ground isn’t frozen, but this isn’t the usual and is rather harsh on the plants.

Even cold-hardy cultivars like Ice Crystal Oakleaf will struggle in the winter.

Hardiness Zones for Hydrangeas

The United States is separated into zones when it comes to the environment that a specific hydrangea cultivar can withstand. The lowest average winter temperature determines each zone.

Hydrangeas of the same kind may be found in many zones. That implies you may plant it in any of these temperatures. Here’s a basic overview.

Planting Procedures

Planting hydrangeas is a simple task regardless of the kind. However, there are a few crucial factors to consider before deciding on a cultivar.

Check the Acidity of Your Soil

Unless you go for something that will stay white like the Arborescens Hydrangea Annabelle cultivar, you’ll probably pick a type of hydrangea that will change color over the years.

You’ll need acidic soil or a pH of 5.5 or below if you want blue flowers. Pink flowers need alkaline soil with a pH of 6.5 or higher to thrive.

By determining the acidity levels in your soil, you may determine what additives are required to get the desired hue.

Understand Your Environment

If you put a hydrangea from a warmer zone in a cooler zone, your plant may flourish, but it will most likely just produce leaves and never blossom.

Choose the Best Location

The first thing you should do is take a thorough inventory of your garden. Hydrangeas need some shade since they cannot tolerate full sun or temperatures in the mid-90s. There are two approaches to this.

To begin, you may follow Mother Nature’s lead and put your hydrangea under the shadow of towering trees.

Hydrangeas thrive under trees in woods. Your hydrangea will get the right amount of moderate, filtered sunshine in this location. Furthermore, tree leaves that fall and perish give your plant with nutrient-rich soil, mimicking Mother Nature.

Alternatively, choose a spot in your yard that only receives early morning sunlight and is then shaded. This protects your hydrangea from the stronger sun and heat of the remainder of the day.

A lovely expanse of color may be created by planting many hydrangea bushes. If you’re going to plant a lot of hydrangeas, be sure to spread them out so that the roots of each plant have enough area to flourish.


The depth and breadth of the hole you dig to plant your hydrangea should be doubled. It’s best not to probe any further than that. Subsoil must be removed.

What Should I Put in the Soil?

When planting hydrangeas, there are a few essentials to include in the soil.

Keep in mind that the quantity of fertilizer you use is determined by the planting season.

Check Amazon for the best price.


When it comes to fall planting,

If you’re planting in the autumn, use less fertilizer.

Fertilizer promotes quicker growth of shoots, which is not the purpose here. You want to promote root growth rather than shoot growth. When the cold weather arrives, your plant will develop a strong root system to weather the storm.

Check Amazon for the best price.


When it comes to spring planting,

If you’re planting in the spring, use a lot of fertilizer.

Your hydrangea now has ample time to establish a strong root system without losing shoot development now that the winter season has passed.

Choose the Positive Side of Your Plant

Remember to flip the pot before backfilling so that the attractive side of the plant is showing.

The Initial Backfill

Combine all of the materials and add shovelfuls until the hole is half-filled.

Check Amazon for the best price.


The First Sprinkle

Thoroughly soak your hydrangea. Leave it alone for an hour or until the water has entirely drained.

Backfilling in the End

Add extra shovelfuls of soil mix until the roots are completely covered.

After you’ve backfilled the hole fully, softly press the earth without compacting it. You must provide enough space for your plant to form roots.

Watering Number Two

Give your plant plenty of water.


Hydrangeas, like other blooming perennials, need pruning once they have completed flowering. They’ll grow to more than twice their post-pruning height in a year if you trim them appropriately.


Feed your hydrangea every two weeks during the summer to guarantee it produces those rich colours.

Hydrangea Varieties

Everyone can find a hydrangea. Take a look at these unique cultivars if you’re not sure which one to choose. Each variety is hardy to zone 3, meaning they can endure very cold conditions.

Rickey with Lime

An exceptionally sturdy type, the Rickey with Lime can withstand rain for hours without snapping.

Wee White Invincibelle

If you want to cultivate hydrangeas but don’t have space for a cultivar that will keep growing, this small plant is suitable.

Spirit of Invincibelle II

This lovely deep-pink hydrangea looks great on its own in the yard. It also blooms well into the autumn. Even better, a dollar is contributed to the Breast Cancer Research Foundation for every plant sold.


Even a black thumb couldn’t kill this plant since it’s so simple to cultivate. It can also withstand extreme temperatures and flourish in zones 9 and 10.

Last Thoughts

Hydrangeas come in enough forms, sizes, and colors to make the options appear unlimited, changing from pink to blue or the other way around, with some blooms even reaching the size of a human head.

Hydrangeas, whether fresh or dried, create strong bursts of color in your yard and make fantastic container plants and centerpiece arrangements.

As long as you Understand Your Environment and soil and pick the suitable cultivar and the right time to plant it, you’ll have a beautiful, delightfully low-maintenance garden plant to enjoy for years to come.
