Deadheading too-tall hydrangeas can occasionally be challenging. Your other option is to keep them on if you don’t have the skills to reach spent flowers or all of the spent blooms. And you can do that without suffering too much harm.
Simply omit deadheading hydrangeas, and your plant won’t suffer. At least nothing major enough to need worrying about.
Your hydrangea might not produce as many or as large of blooms as it would have if the spent blooms had been removed. It will nevertheless continue to bloom.
Having said that, you can think about pruning hydrangeas that have gotten too tall in order to make them smaller and easier to handle.
This will make it simpler for you to maintain the tidy appearance of your hydrangeas. Additionally, it will make it simpler to remove spent blooms from plants and promote future blooms with greater vigor.
Does deadheading hydrangeas make sense?
To keep your hydrangeas looking their best and promote the development of new flowers, deadhead regularly during the blooming season.
But in mid- to late-fall, stop deadheading hydrangea shrubs, leaving any spent blooms in situ. This not only adds beauty to the winter landscape but also guarantees that the buds that will bloom the following spring are not removed.
What occurs if hydrangeas aren’t pruned?
Hydrangeas can eventually resemble a tangled jumble of woody stalks if they aren’t pruned, and their flowers will get smaller and less beautiful as a result. Lack of pruning is frequently the cause of your hydrangeas’ failing to bloom.
Regular pruning of hydrangeas promotes new growth and a better display of blooms while also helping to keep them in form.
The experts at Thompson & Morgan say that “it’s this vigorous, new growth that ensures you have lots of huge, healthy flowers to enjoy in the years to come.”
When should dead hydrangea blossoms be removed?
These are your macrophylla hydrangeas, also known as mophead and lacecap, which come in purple, pink, and blue. They also include hydrangeas with oak-shaped leaves. While reblooming kinds flower twice, some cultivars only bloom once per season on stems from the previous year (old wood).
The initial set of hydrangea blossoms should be deadheaded as soon as they start to turn brown and dry. Cut the stem immediately above the first set of leaves and below the flower head. When this second set starts to fade, you can deadhead once again for reblooming varieties, but only until about mid-August. Your hydrangeas will then produce buds for the flowers of the next year; you don’t want to unintentionally cut these off. After the summer has ended, dried flower heads can remain on the shrubs to add visual interest over the winter.
In the summer, should I deadhead my hydrangeas?
You ought to be deadheading the spent flowers all through the flowering season. Just above the first pair of leaves that are opposite one another, follow the stem down. You should cut this off to promote new growth.
Your hydrangeas will look better overall and be ready for the next year if you deadhead them. Early April is when the hydrangea growing season begins. The shrub’s longer branches can be clipped by gardeners to display the hydrangea blossoms in vases. Early summer is the ideal time to deadhead to encourage growth.
Your hydrangea is most likely developing new buds for the following year after August. It’s a strong, positive plant! Before cutting, run your fingertips down the stem to feel for any bulging new flower buds. Make sure to avoid any bumps you feel or see by cutting safely over them.

What occurs if pruning is not done?
The trees on your lot have a lower chance of thriving and increasing the value of your property if you don’t prune them. Frequently unpruned trees include:
1. Diseases will spread from the Tree. Like many other plants, trees are susceptible to disease, which can then spread to surrounding trees as well as the diseased tree’s branches. Tree pruning prevents the spread of arboreal illnesses throughout your entire neighborhood, including your own garden.
The Tree Shall Perish 2.
Failure to remove diseased branches from a tree that is fighting for its life after contracting a disease could lead to the loss of the entire tree. The illness cannot spread because to tree cutting.
3. Damage Can Be Done By Falling Branches
A tree’s dead or dying limbs are easily torn from it during a strong wind or a storm. These branches can harm nearby automobiles, furniture, fixtures, and anyone unlucky enough to be standing underneath them. The limbs of a tree may encroach too closely on windows or power lines if it isn’t properly clipped. Branches could damage the side of your house or even shatter a window if they aren’t clipped.
4. Fruit production on the tree may stop.
Dead leaves and branches deplete the energy of the rest of the tree, just like a plant does. A tree that has an excessive number of dead limbs will become unhealthy and bear very little fruit. The best technique to promote new growth and raise your production is through tree pruning.
How far in advance should hydrangeas be pruned?
My two hydrangeas are quite robust, yet they never bloom. How far back should I clip them now, and what can I do to encourage flowering?
A: I followed up by inquiring as to when Tony typically anticipates his hydrangeas to bloom and whether or not he has been routinely pruning them.
They used to bloom in the late summer, according to Tony. He trims them to the ground in the fall.
Usually, incorrect pruning or inadequate light are at blame when hydrangeas stop blooming. It is likely that Tony’s hydrangea bloom on new wood because they do so in the late summer.
It would appear that, despite being a bit early, cutting them back at the beginning of fall has been effective for him. That shouldn’t be a problem because hydrangeas that bloom on new wood are often pruned back during dormancy, from late fall to very early spring.
Since we have a highly active deer population that regularly strips any hydrangeas they can reach, these hydrangeas are a particular favorite of mine.
Growing plants that bloom on new wood allows me to cut back on my late-winter trimming while still allowing the plants to bloom on the new growth the following spring. Deer can eat these plants.
A change in the light is another potential reason. If the plants are grown in a space alongside other plants, it is common for the flowers to diminish over time as the neighboring plants swell and cast more shade.
Although hydrangeas are actually understory plants, we tend to think of them as shade plants. As the amount of shadow rises, however, fewer blooms are produced.
Another option is that there will be more deer, or that a herd will move into Tony’s area, which happens frequently whenever there is new construction, whether residential or commercial, which drives animals out. Deer can cause damage as they travel into places that weren’t previously hotspots since they eat throughout the year. Deer tend to eat delicate shoots and buds from plants.
For instance, we have spent around 17 years in our current house. My hostas and daylilies were mostly unharmed during that time. Nearby, significant projects have been constructed over the past few years, decimating my hosta bed and removing the buds from my daylilies.
This year, we even saw fawns hiding in the front yard by some plants. A bush outside my kitchen window with lovely white variegations on the dark green leaves was one of my favorites, but others, like hydrangeas on a steep slope, have been eaten down.
A: I’ve pruned two out of the three hydrangeas in Westmoreland County, southwest Pennsylvania, just south of Greensburg. I typically trim down 3 feet or so when they reach a height of approximately 9 feet. I was unable to reduce the last one this year because to weather and a backache. Do you believe cutting the final one now will affect No. 3 more than waiting for a day or two of 40 to 50 degrees, which it appears may occur? Or could you just trim the edges off the flower? Thanks.
A: Tom must respond to the same inquiries I posed to Tony. He typically prunes while the hydrangeas are in blossom. It is too late to prune the plants back without losing at least some of the flowers for the following year if they bloom on wood from the previous year.
He ought to be able to remove the dead blossoms without losing any flowers. Tom should trim the wasted flower stem back to just above the next node (where the leaves or branches emerge from the stem).
He can safely cut his plants until early spring if they bloom on new wood because the flower buds for the following year have not yet formed.
Another choice is to do nothing; although his hydrangea will grow bigger the following year, it won’t suffer from lack of pruning. Cutting off the old blooms is a possibility in both situations—new wood and old wood—even though some plants produce hardy flowers that provide the barren landscape some winter charm.
I observe that it is wise to remove old stems from hydrangeas when pruning in order to keep the interior light- and airy-filled. It would be preferable to begin by performing some basic maintenance trimming before chopping back the branches, even though he may be pruning for size. Prior to trimming the length of the remaining branches, look for any broken, diseased, or rubbing branches.
More on holiday plants
I talked about some of the popular tropical plants used for decoration last week. Others, like holly, mistletoe, and cut greens, have the opposite requirements.
Despite appearing to be evergreen, all of these plants require moisture, so you should think about misting them, especially if you plan to exhibit them indoors.
Holly is actually better kept outside since, as they dry and fall, the prickly leaves hurt to touch. Additionally, the holly lasts a lot longer outside.
Another plant that needs particular care is mistletoe. Most sprigs have fake white berries, but others have actual ones. Watch out for any dropped mistletoe berries because they are deadly, especially if you have or anticipate guests who will bring pets or small children.
The greens, wreaths, and garlands are intended for temporary inside display, so it’s time to move them outside when they begin to lose a lot of needles or turn brown.
If you utilize cooler LED lights instead of hotter incandescent ones, the displays with lights will last a lot longer.
Week in the Garden
Planting:
- To add color to the winter landscape, use holly, miniature evergreens, cut greens, and pansies.
- Remaining spring-flowering bulbs should be potted and kept at a cold temperature of 40 degrees or lower for 8 to 12 weeks before being brought inside for forcing.
- Plant seeds that need a period of cold weather for germination.
Seasonal:
- Buy Christmas presents and gift cards for gardeners on your list.
- Clean, examine, fix before hanging decorations, and throw away broken ones. Secure all decorations to prevent loss or damage during windy or stormy conditions.
- Clear dead plants and leaves from paths.
- Permit seed-producing plants to stay on the plants so that wildlife can eat them.
- Find a planting location, dig the tree out, and put the soil in the garage if you are buying a live Christmas tree in a pot or wrapped in burlap.
Lawn:
- On the grass, rake, blow, or mulch fallen leaves. Matted leaves can prevent water from reaching the soil and promote mold issues.
- Water freshly seeded or sodded lawns until the ground freezes, and provide additional watering during weeks with less than an inch of rainfall.
Chores:
- To prevent winter damage, bring mobile pots and garden ornaments inside, or wrap large statues. Terra cotta, clay, or plastic empty pots should be kept in a dry, protected environment to prevent breaking.
- Till extremely early spring or late winter, stop pruning.
- Mark off new plantings, beds, delicate plants, and plants that are slow to emerge from winter dormancy in the spring. When decorating or removing snow, stay away from them.
- When the ground freezes, spread mulch for the winter.
- To check for new growth, inspect stored amaryllis bulbs. Water, followed by a warmer location and gradually increasing indirect light.
- Garden waste should be removed and composted. Get rid of or destroy sick or infected plants.
- Topdress now with compost or manure, then till the following spring.
- Until the ground freezes, water any new crops whenever we go more than a week without receiving more than an inch of rain.
- Check the caulking on the windows and doors. Make repairs right away to keep mice, ladybugs, and stink bugs out.
- Remove any standing water.
- Protect delicate plants from deer, rabbits, and groundhogs. Reapply taste or odor inhibitors.
- Regularly clean and restock bird feeders. Clear away the empty hulls and spilled seed. At least once each week, empty, scrub, and refill birdbaths. In cold weather, think about getting a heater.
- Rainwater runoff should be directed away from building foundations by clearing gutters.
