All of this does not, however, guarantee that your beds, pathways, and trellises will be taken over by hydrangeas. A clever gardener may incorporate these profusely flowering shrubs into a well-planned garden using a variety of techniques.
: Choose the Right Variety
Before you get your plant home from the nursery is the optimum time to start managing its size. Look for a variety that will fit in the area of your garden that needs to be filled, even after it has grown to maturity. Not all hydrangea varieties grow into towering hedges. Even in their best growth environments, many dwarf cultivars maintain their modest size while producing lovely blooms.
If you want something compact, think about one of these Hydrangeas:
Small Quickfire This panicle hydrangea blooms early and has fluffy-looking white flower cones that mature to soft reds and purples. Its mature height will be between three and five feet.
Penny Mini. The Mini Penny, a diminutive variation of the popular Mophead Hydrangea, grows to a maximum height of three to four feet while producing the same abundant, vibrant flower clusters as its larger relatives. You’ll get blossoms in both the spring and summer because it blooms on both new and old wood.
Small Lime. The blooms of this additional panicle type, a little variation of the well-known Limelight Hydrangea, start out green in the summer and turn pinkish-red in the fall.
Time to dance. These tough Lacecap Hydrangeas keep their size to a manageable two to three feet. However, they produce enormous pink or tiny blue petals, making them flower powerhouses.
PEEE WEE This tiny version is worthwhile to look at if you enjoy the beautiful white blooms and the crimson fall foliage of Oakleaf Hydrangeas. When fully grown, it is about four feet tall and three feet wide.
: Give Them Plenty of Sun
Hydrangeas want to welcome the sun every morning, just like your yoga instructor. Early morning sunlight is ideal for them; if you set them in an area that is too shaded, they may reach higher in an effort to catch those priceless rays.
Avoid going overboard, but the optimum location is typically one that receives some shade during the warmest part of the day.
: Don’t Over-Fertilize
You probably use some kind of fertilizer on your hydrangeas, whether you think chemical can improve gardening or you’re a compost-only kind of person.
However, if your bushes are outgrowing their capacity, cutting back on their food is a quick and easy solution to get them to back off. In fact, it’s almost always preferable to use too little fertilizer than not enough. A single application of a controlled-release fertilizer in the springtime should be adequate.
: Grow Hydrangeas in Containers
Hydrangeas are voracious growers, but if their roots are confined by ceramic or stone, they can only grow so far. You can prevent them from spreading too far by growing them in a pot. Of course, the correct container can also stand alone as a chic accent to your yard.
Non-dwarf hydrangeas can be grown in containers, but pruning may still be necessary. In order to prevent the soil from drying up too quickly after watering, you should still choose a pot that is a good size, measuring at least 18 to 20 inches around.
How can I prevent the proliferation of my hydrangea?
Is there anything that can be done to prevent the hydrangea roots from spreading? On the side of our driveway, they “popped” up in a certain spot approximately 5 or 6 years ago. They have expanded excessively, like a wildfire. I tried to pluck them, but it was unsuccessful.
Persistence and a little hard work should be enough. What you want to preserve intact, edge. Cut the rhizomes (underground stems that resemble roots) with a sharp spade to separate the hydrangeas you want to maintain from those you want to get rid of. Whenever the undesirable stems appear, continuously prune them to the ground. These stems ought to become weaker and eventually perish. Alternately, carefully apply a complete vegetation killer to the unwanted sprouts. All plants, even the ones you want to maintain, risk injury or death if the rhizome is not severed before spraying. When using conventional or new environmentally friendly products, read and carefully abide by all label instructions. All of these items are plant killers and can harm or kill both your desired plants and weeds.
Can hydrangeas be pruned to keep them small?
One of the hydrangeas that blooms on new growth is called Annabelle. However, if you extensively prune them, they will still bloom. If you prune them too much, the new growth that develops may be weak and bow when the flowers are in bloom.
How do I prune my hydrangeas? is the query I receive the most on GardenLine. The big-leaf hydrangeas, Hydrangea macrophylla, have a difficulty in that if you cut them back too much, they don’t bloom as much the next season because their flower buds develop in the previous summer. On old growth, the majority of the well-known blue mophead and blue, pink, or white lacecap hydrangeas produce blooms.
However, some hydrangeas do not bloom on second year growth, which furthers the uncertainty. Both the white-flowered ‘Annabelle’ and the extremely hardy Pee Gee hydrangea, Hydrangea paniculata ‘Grandiflora, bloom on fresh growth. Several kinds, including “Penny Mac,” “All Summer Beauty,” and “Endless Summer,” bloom on both fresh and old foliage.
Let’s first discuss why you should prune these bushes before moving on to how. Unfortunately, the most common motivation for pruning a plant is to reduce its size. You’re destined to lose unless you’re cultivating a shrub or tree in a bonsai dish.
Plants should typically only be clipped to enhance appearance rather than regulate size. I’ll say it again because it’s crucial: Hydrangeas should be clipped to enhance look rather than regulate size. The mature hydrangea shrub is an immovable object. A big leaf hydrangea will grow back the following season if you prune it one year. Replace your larger growing variety with one that is genetically engineered to stay short if you wish to keep them little. A few types are recommended later in this article.
Many lacecap hydrangeas flower on growth from the second year, thus they should be treated similarly to mopheads. For illustrated pruning instructions, download the pdf document found at the end of this post.
Pruning instructions for lace-caps, mopheads, and big leaf hydrangeas are as follows:
1. When the plant has started to emerge from dormancy in the spring, prune. You can tell which canes are alive and which are dead at this time of year.
2. Start by cutting all dead canes down to the ground and eliminating them. In order to avoid being tempted to leave unsightly, six-inch-tall stumps because you can’t reach to cut them any shorter, it is better to do this while seated close to the plant.
3. After removing all dead canes, assess what is left. If you still have a lot of surviving stems and some of them are older than three years, cut the oldest canes again at ground level and eliminate a third of them. New growth will be encouraged by this. Skip to step #4 if the plant is not overcrowded with numerous older stems.
4. Trim any remaining faded flowers to thin the plant. Working from the top down, trim the remaining canes back by stopping and making the cut just above the first or second pair of buds you reach. Some canes will be cut very little or not at all when using this top-down strategy, while others will only contain surviving buds close to the base of the plant, meaning you’ll be chopping off a significant portion of that stem.
5. After that, back up and inspect the plant. If there is a stem that is noticeably higher than the others, you can cut it to make it more in proportion with the others if you prefer the way it looks. Remove any curved, frail-appearing branches that trail on the ground.
6. Bear in mind that any green buds you remove could later on in the summer bloom. Do you like more flowers or a cleaner plant? Keep in mind that you may always cut those flowers to make bouquets, which would help the plant look better later in the year.
7. Prune Infinitely Summer and other large-leafed hydrangeas that similarly bloom on fresh growth. Cutting these plants short results in fewer flowers because they bloom on both new and old wood.
8. Do you want them to be small? Let it go. Plant “Mathilda Gutges,” which is my favorite hydrangea, as well as “Hortensis Compacta,” the diminutive “Pia,” and “Pink Elf.”
Hydrangeas like the one on the right, called “Mathilda Gutges,” are suitable for perennial gardens and foundation plantings because they don’t grow much higher than four feet. The hydrangea “Ami Pasquier” on the left can reach heights of over five feet and should be planted in an area where it will have room to develop.
‘Pee Gee’ hydrangeas can be pruned in a variety of ways. By pruning deadwood and one-third of the smaller lateral branches each year, some people help them grow into little trees. Remove these twigs, leaving just the larger, upright stems, and the plant will grow taller, resembling a miniature tree with many stems. Cut out any crossed branches or those that are growing toward the center of the plant rather than away from it after cutting the deadwood and those lower stems. Do this in the spring or late winter.
Pee Gee hydrangeas can also be pruned annually to a height of six inches to three feet. But because the top tends to grow thicker, the new stems that emerge will be dragged down by the weight of the blossoms. Pee Gee hydrangeas should generally be planted in areas where they have the potential to grow huge. Consider the diminutive oak leaf hydrangea, Hydrangea quercifolia ‘Pee Wee, if you want a white flowering shrub that stays small.
If Annabelle hydrangeas are pruned short, the stems will bend under the weight of the flowers since the fresh growth is weaker. These should be pruned similarly to mopheads, in my opinion.

How should I arrange my garden’s hydrangeas?
Plant hydrangeas closely together to form a trail that will guide guests to a garden gate, porch, deck, or other location. These hydrangeas, which are called “Tardiva” and “Annabelle,” can be clipped to prevent them from obstructing the view out of the house’s windows.
What’s causing my hydrangeas to tumble over?
There are various reasons why hydrangeas droop, although disease is a rare one. Hydrangeas frequently show their displeasure with the environment by drooping. Welding is caused by too much sun, not enough water, and excessive flower loads, which can force delicate branches to bend till they touch the ground. Droopy hydrangea plants could be caused by even an excess amount of fertilizer.
Your hydrangea will need special care in order to solve the issue. Before attempting to address the factors that caused the first droop, you’ll need to play detective to ascertain what’s wrong with your plant. Finding the root of the issue could only require a soil test and some attentive observation.
How can I shorten my hydrangeas’ lanky stems?
One of the nicest flowering shrubs out there, according to anyone who has a hydrangea in their garden. But if your hydrangea grows to be “leggy,” it might not be robust enough to support those enormous, gorgeous blooms. You can give your hydrangea some tender loving care to help it develop a strong base for years to come.
The best thing you can do for your lanky Hydrangea is to make sure it receives adequate sunlight. After that, pruning will promote new growth and create a stronger foundation for future blooms on your hydrangea. Your Hydrangea will stand taller if you deadhead blooms that are starting to wither.
There is no reason why you shouldn’t have one of these stunning beauties in your collection since hydrangeas are a feature of any southern landscape. Learn how to maintain your Hydrangea looking rich year after year, whether you’ve just planted a new one or your plant is simply looking too spindly.
When ought hydrangeas to be pruned?
Depending on which group the plant belongs to, the timing and extent of pruning are determined:
Advice on Pruning for Group 1:
- As the days get shorter and the weather gets colder in the late summer and fall, buds for the following year’s blooms start to form.
- Typically, removing dead, diseased, or damaged branches is all that is required to preserve shape, size, and a healthy plant. Otherwise, gentle pruning ought to be practiced.
- In the summer, trimming should begin as soon as flowering ends, but no later than August 1. Pruning should not be done in the fall, winter, or spring because you risk removing fresh buds.
- Tip-pruning the branches in the spring as the leaves begin to appear can promote more numerous, smaller flower heads as opposed to fewer, larger flower heads.
Advice on Pruning for Group 2:
- On the growth of the current year, flower buds form.
- Early in the spring, as the leaves are starting to emerge, prune.
- Just above a node, prune branches back by half to a third.
- After that, prune any fragile or spindly branches.
- Minimal trimming encourages huge, strong bushes with many of tiny flower heads in H. arborescens. Hard pruning between 12 and 18 inches from the ground, or even all the way down, will result in fewer but larger flower heads that may flop if unsupported.
- For H. paniculata, remove the surrounding smaller wood while leaving the larger stems in order to establish a sturdy foundation.
Pruning may be connected to flower head size. Shoots will grow more vigorously and flower heads will be bigger and fewer with more rigorous trimming. Smaller but more numerous flower heads may result from less aggressive or tip pruning.
Consideration of hydrangeas’ mature size is the best piece of advise. Place them in a location where they won’t outgrow and won’t need a lot of pruning to keep them in check. Hydrangeas don’t need to be pruned precisely or often; as long as dead wood is removed, they will remain healthy and continue to develop and bloom.
Should hydrangeas be tied off?
To avoid disturbing the roots later, put a stake when planting plants that need to be staked in order to stand tall. But after a few years, hydrangeas might need to be staked because their blossoms get too heavy, especially after rain. This issue is common with Annabelle hydrangeas (Hydrangea arborescens ‘Annabelle’), whose blossoms sometimes droop to the ground and are hardy in U.S. Department of Agriculture plant hardiness zones 3 through 9. Any hydrangea species that you are growing can be staked as soon as the stems start to droop.
