Your yard, garden, or borders will stand out with large, blooming hydrangea plants. Large and spherical, hydrangea flowers bloom in the summer in deep pink, blue, or purple hues, and hardy hydrangea shrubs can keep their blooms far into the fall. A healthy hydrangea bush spreads 3 to 5 feet across and produces several blooms throughout the course of its protracted flowering season.

Placement of hydrangeas might be a little challenging. While some hydrangea species prefer full sun, others prefer a more gloomy setting. While panicle and climbing hydrangeas may tolerate the intense afternoon sun, not all hydrangeas thrive in it. In full sun, panicle hydrangeas really flourish. In hotter climates, macrophylla and serrata won’t just wilt; they’ll burn up in full sun, so give those hydrangeas some afternoon shade. Although oakleaf can tolerate direct sunlight, they also need some afternoon shade in warmer climes. There are many different varieties of hydrangeas, so read the instructions on your particular plants.
With the proper care, hydrangeas are perennial plants that will bloom every year! To give your hydrangeas the best chance of living a long and fulfilling life, plant them in a well-drained, mostly sunny area. For the first year or two after planting, these plants require a lot of water. Additionally, they can benefit from a light fertilizer twice a year, once in the spring when the buds begin to put forth new growth and once in the summer. After the middle of August, hydrangeas shouldn’t be fertilized. This enables all new growth to harden off prior to the arrival of cooler weather. A little winterization in the fall will enable them to recover more quickly and effectively than before.
In the fall, mulch your hydrangea plants’ roots with bark, leaves, pine needles, or straw to a depth of at least 18 inches before the first frost. You can actually cover a portion of the canes with macrophylla and serrata kinds as well. By safeguarding the flower buds that have developed during the summer, this insulation will assist ensure blossoms the following year. In the spring, be sure to carefully remove the mulch covering the canes.
Hydrangeas are frequently eaten by deer, especially in the winter. Deer will graze all varieties of hydrangea, and depending on other food sources nearby, they may do a fair amount of harm. Deer are known to browse on oakleaf and arborescens hydrangea in particular. Therefore, it is better to cover the hydrangea’s accessible areas in wire or a deer cage. Try using a commercial deer repellent if that doesn’t deter your deer.
The hydrangea variety determines the trimming schedule! Certain hydrangeas, such as oakleaf, bigleaf, and climber varieties, require quick pruning after flowering. Hydrangeas with smooth or pinnate leaves can be clipped before spring.
Make sure to prune before autumn for kinds that need to be clipped right away after flowering because flower buds actually grow in the late summer and bloom the following season. In the spring, after the plant has fully flushed out, any dead wood should be removed. Before pruning, ensure sure there is no new growth visible on the cane. You don’t need to deadhead a hydrangea, so leave the blossoms on the branches you aren’t pruning back. Don’t overprune the wood; these plants prefer aged wood to fresh growth. Although fantastic new breeding has produced macrophylla and serrata cultivars that do bloom on new wood, the overall pruning recommendation for these hydrangeas remains the same: prune lightly.
When the plant is dormant and before fresh flower buds have grown in the late winter, you should clip smooth and panicle hydrangeas. You can prune to shape the plant and get rid of crossed branches and aged wood. On “new wood,” panicle and smooth hydrangea blossoms bloom.
What occurs if hydrangeas are not pruned? If you don’t prune your plants, you might have smaller blooms, but it won’t do any harm to the plant. The majority of hydrangeas are content to grow unpruned and will still bloom each year.
Hydrangeas are not deer resistant and animals don’t particularly like them, but if food is scarce enough, deer will undoubtedly turn to eating your hydrangeas. Typically, winter is when that occurs.
On aged wood, hydrangeas such as mophead, serrata, climbing, and oakleaf bloom. Winter damage may heal before the hydrangeas bloom because many other types have flowers that bloom on fresh wood. You do not, however, want deer to view your yard as a smorgasbord. They are creatures of habit, and they frequently revisit settings that have provided simple meals in the past. We advise using a wire cage in the winter for short hydrangeas. Try applying deer repellent to the reachable branches of taller hydrangeas.
Some hydrangeas actually change color—mostly the macrophylla and serrata varieties! The pH of the soil will have an impact on the blossom color in some varieties of these pink-to-blue hydrangeas, such as Tellers Blue or Twist n Shout hydrangeas. In extremely acidic soils, these flowers turn more blue, while in slightly acidic to slightly alkaline soils, they turn purple to pink.
You must increase the soil’s pH in order to make the hydrangea flowers more pink by making the soil more alkaline and less acidic. Try putting some lime in the soil to give the blossoms a more pink appearance. Magnesium will also be added to the soil by dolomitic limestone. Wood ash will help increase soil pH, but it should only be used sparingly because too much might burn the foliage of your hydrangeas.
Although hydrangeas with a bluer color are frequently connected with lower soil pH, low pH won’t automatically turn your hydrangeas blue. Hydrangeas need aluminum to change from pink to blue, thus an acidifier lacking aluminum may not have the same result. Availability of aluminum in the soil varies, but it is generally rather common, thus search for amendments that contain aluminum. Aluminum ions are trapped with other components in excessively alkaline soils and do not reach your plant. The aluminum ions can be released and taken up by the plant by lowering pH, which results in the blue color.
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. Many people plant hydrangeas in beds next to their homes 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.

Depending on the soil pH, BloomStruck has deep blue-purple or deep pink flowers with super-strong red stalks and a more compact growth habit.
Let’s Dance Can Do
Let’s Dance, We Can As opposed to most bigleaf hydrangeas, which only produce flower buds at the top of the stem, hydrangeas produce flower buds all the way down the stem. This means that even if there is a late-season frost, flower buds may still form in the early summer. Depending on the soil, the plant has gorgeous lavender or strawberry pink lacecap blooms.
Limelight Prime
Large blooms on limelight hydrangeas that shine in direct sunlight are their trademark. From bud to bloom and beyond, the new Limelight Prime panicle hydrangea outperforms the old Limelight in every way. With bolder, better flower color and much stronger stems, it blooms earlier. It is also one of the easiest hydrangeas to grow and is a more useful, compact size.
Fire Light Tidbit
The smallest and cleanest panicle hydrangea is Fire Light Tidbit. Its height and width are only 2 to 3 feet, yet it has a lot of low-maintenance beauty. It has large, dense panicles of early- to mid-summer white mophead blooms that almost completely cover the textured green foliage. It produces a compact, mounded plant that looks great in landscapes, flower gardens, and even in containers because to its strong, thick stems.
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.
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.
How late may hydrangeas be planted?
When may I put a hydrangea in a planter outside? Anytime of the year is suitable for planting a potted hydrangea in the ground. The ideal seasons are, however, spring or autumn. Plant either in early fall when the soil will still be warm and before the frosts or after the spring frosts have passed.
What type of hydrangea is the simplest to grow?
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.
