Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
If deadheaded, do hydrangeas bloom again?
Hydrangeas cannot be revived by deadheading like other flowers can. Reblooming hydrangeas produce a second set of flowers on fresh stems later in the season compared to regular kinds, which only bloom once each season. When deadheading hydrangeas, the goal is to keep the shrubs looking tidy and to direct plant growth toward roots and leaves rather than seeds.
Bobo hydrangeas require pruning, right?
Although it may grow in a variety of soil types, the Bobo hydrangea does best in loamy soil. Regardless of pH levels, trimming, or soil conditions, this shrub will bloom. Although this plant is quite compact and shouldn’t require pruning, you can clip the Bobo Hydrangea in late winter or early spring because this shrub blooms on new wood.
Early in the spring, treat the Bobo hydrangea with a slow-release fertilizer made for bushes and trees.
How should hydrangeas be deadheaded?
Myers asserts that how you deadhead your hydrangeas is just as crucial as when you do it. Make your incision directly above the first set of full-sized leaves, which should be situated beneath the blossom, she instructs. “You are essentially eliminating the faded blossoms to expose a set of sound leaves. This can be carried out immediately following flowering, in late winter or early spring.”
What happens to hydrangeas if I don’t deadhead them?
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.
What makes deadheading and trimming distinct from one another?
Fortunately, all you need for this project are some clippers, gloves, and a pail to gather your cuttings. I really appreciate this multi-snip tool that I discovered last spring for this gardening task because deadheading is typically a little more delicate than full-on trimming. Use anything you have, including regular bypass pruners.
Since I normally go through 1-2 pairs of gloves in a season (due to holes in the fingertips…), I bought these gloves last spring. I was impressed by how lightweight but robust they are. Since I have spare pairs accessible for any garden assistance I may hire, I haven’t even pierced the first pair’s fingertips yet.
General Pruning-Deadheading Tips
(Note: pruning refers to removing any portion of the plant, from large to small – what we’re doing in the summer is small, just cutting back some and trimming.) Deadheading is the practice of removing wasted flowers from plants.
The majority of your perennials and shrubs that have bloomed or are still blooming only require that you “deadhead,” or cut off the spent blossoms. To determine where to cut the dead flower, consider the following two factors:
- Like this buddleia in the picture above, you can prune it back to the first sign of new growth. This small variety (Lo & Behold ‘Ice Chip’) will continue to bloom into the fall thanks to those new stems on the sides that will bear additional flowers.
- OR, you might prune it more, taking further cuts to keep it under control for the planting area. To prevent the plant from getting too huge or to assist it maintain a more aesthetically acceptable form, continue to look for new growth, but further down on the stems.
You’ll also find plants with dead flower stalks and leaves, like the daylily in this image. Your garden will look better into the fall if you take the effort to remove the browning, dead leaves and deadhead the flower stalks. The majority of daylilies have finished flowering, but they will continue to provide grass-like leaves as a backdrop to the garden. However, some types, like Stella d’Oro, will continue to bloom if the dead stalks are removed.
Shearing the plant back is the simplest approach to get rid of all the wasted flowers on perennials with tiny blooms, like hardy geranium. Once the majority of the wasted blooms have been removed from the plant, grab pieces with your hand and chop the entire part off. For a week or two, it won’t look its finest, but it will soon sprout new growth and produce more blooms.
The heavy blooms on mature hydrangeas may be causing the plant to bend and dip, exposing the crowns. It’s the ideal moment to remove the oldest blossoms, especially those at the bottom, so that the leaves can reposition themselves. If you cultivate a reblooming hydrangea, such as Endless Summer, it will keep producing new flowers for you.
The act of gathering all the blooms and decorating the home with vases of fresh flowers after hydrangea trimming in the summer is the greatest part!
You’ve undoubtedly been deadheading individual rose blossoms as they appeared over the previous few months, but your shrub will bloom more quickly if you trim back to a five-leaf junction, where new growth and blooms will develop.
Additionally, you should prune back to new growth to remove any damaged leaves and stems (like I obviously have on some of my roses – if you live in the Pacific Northwest, every rose will get blackspot…). This not only improves the appearance but also helps prevent disease from spreading to the new growth.

Hydrangeas called Bobo flop?
Without including hydrangeas, no discussion of a summer landscape in the Midwest is complete. A hydrangea is, to put it simply, a large-leaved blowsy shrub recognized for its dazzlingly brilliant flowers. I should explain my viewpoint on shrubs in general before I make any comments about hydrangeas. Any shrub that can enhance a landscape is appealing to me. Shrubs seem to work well year after year with very little upkeep. Some medium-sized shrubs, like spirea, not only can withstand being chopped to the ground in the spring, but they also quickly recover and blossom. Other shrubs not only put up with improper trimming, but even thrive under it. New varieties of miniature shrubs, such as dwarf butterfly bushes, are suited to small gardens. Large shrubs might block an unfavorable view. Shrubs live a respectably long time. They don’t ask for much and provide a lot.
They fill the space between the trees above eye level and the low-lying perennials below. The extensive list of maintenance requirements that perennials demand is replaced by a yearly pruning. If your garden is small, be selective in your selections of shrubs because they do take up a lot of space. Both a perennial garden and a group of trees can benefit from hydrangeas. They can make a garden heavier. Greenish white cone-shaped flowers on Lime Light hydrangeas can support a perennial garden. They have a lengthy blooming period. Their twigs stand solidly straight up.
In my zone, the hydrangea Annabelle has been blooming since June. For them, this year has been fantastic. They are standing up very straight and covered in blossoms everywhere I see them. The Annabelles have never really been a favorite of mine. Their propensity to topple over need careful staking well before the developing and flowering stages. What a hassle. Everywhere I see those enormous white blooms this year, they look fantastic. both staked and un staked in the shade and the sun. I believe our frequent and heavy rain has been really beneficial for them.
This garden has three rows of annabelles and two rows of lime lights, so the hydrangea bloom period will be prolonged. An embarrassment of riches in hydrangeas, 5 rows of them. The Annabelles, on the left, begin to bloom in June and gracefully drop over a rugged boulder wall. Late July marks the start of blooming on Limelight hydrangeas’ taller, more vertically rising backstop. A rear terrace is at least 150 feet away from this garden. From a distance, all of that white will be easy to read. A perennial garden with a magnificent white covering of hydrangeas supporting it is not visible in this photograph.
The three rows of Annabelle hydrangeas were planted directly behind this rock wall. Their propensity to sag will make this wall more pliable. They will offer the perennials in front of the wall a lovely and welcoming backdrop. When they were first planted, the Limelights at the back were undetectable. However, they will add another, taller layer of white to the perennial garden by the following year.
Dry soil is not good for hydrangeas. There is a dire need for water for these Annabelles. They might bloom, but if they don’t receive frequent irrigation, the blossoms will burn. Get the hose out and water the interior of your hydrangeas if the leaves are turning yellow and falling off.
I also cultivate Bobo, the shortest member of the Limelight species, and Little Lime hydrangeas, which reach heights of 4-5 feet. They are the ideal height for a small garden at 30 inches. or for a low-maintenance foreground garden. They are a fantastic option for situations in the landscape when a short, wide plant is required. Like a duck to water, this hydrangea enjoys its perennial neighbors. The other colors in a garden are emphasized and set off by the white flowers.
In April, I prune my lime lights. I hold off until I notice the buds swell. My 50 plants are often cut back to, say, 30 tall. each two years. I don’t cut them close to the ground when pruning. Fewer and larger flowers arise from really severe trimming. Larger blooms do not fascinate me. I enjoy several, medium-sized blooms. At home, I choose towering Lime Lights that are surrounded by an aged Hicks Yew hedge. I sometimes remove the old flower heads and leave them alone. You’ll get long, woody legs if you only do light pruning. I may possibly reduce them to 30 the following year. My yews hide those arthritic legs. Take your hydrangeas down closer to 30 if they are in the foreground. Irregularly. Trim each branch separately to ensure that it has a sufficient amount of air and light. If you dare, you can prune to 14 inches above the ground. Do not stoop any lower. On a shrub, forcing development from below the ground is difficult.
A lot of people have asked me about how far apart Lime Light hydrangeas should be planted. There isn’t a right or proper spacing, in my opinion. The design objective influences the spacing decision. If I want to grow a dense, uniform hedge, I space them at 30 or 36 on center. Close spacing means that the hedge grows and thrives as a single organism along its whole length and width. The several plants entwine and merge into one. A hydrangea hedge has never complained about the spacing before. There is an option for a 6 foot spacing. This row, however, cannot be understood as a hedge. The text will appear thick and thin. Wavy. One year they were spaced at 6 feet apart, and the following year they added an interspersing plant.
Hydrangea hedges convey a powerful message. As a foundation planting, a single hydrangea always appears odd and lonely. The best landscapes seamlessly incorporate each plant into the larger overall. I enjoy grouping hydrangeas. Several of a showy shrub like this should be planted. Create your gardens in their vicinity. Be benevolent.
The Lime Light flowers will start to turn pink in late September. This hue indicates that the season is winding down.
The pink becomes deeper in October. From July through October, I look forward to this vista from my rose garden. The dried flower heads remain in place throughout winter. There is a big and diverse list of plants that thrive in my zone. This bush gives me a great deal of different pleasures. I couldn’t live without hydrangeas.
Should I remove the spring blooms of my brown hydrangea?
Pruning is not typically thought of as one of the many gardening activities that may be done in the fall, despite the fact that there are several. It can be difficult to cultivate hydrangeas successfully in New Hampshire, and if you want your plants to blossom, there is frequently very little room for error in pruning.
Wait until Spring to prune hydrangeas
In New Hampshire, hydrangeas come in a variety of kinds, and each one has quite distinct growth patterns and pruning needs. Some plants only produce flowers on fresh growth, while others mostly produce flower buds on older wood. In any case, it is better to postpone all hydrangea pruning until spring. Hydrangeas, as with all other trees and shrubs, go dormant in the fall. Not much new growth is produced by them until the next spring. As new growth is more vulnerable to harsh cold at the location of wounds, plants that have been trimmed now run a higher risk of winter damage. Additionally, fall pruning may lessen the quantity of June blooms.
Considerations for pruning hydrangea species commonly grown in New Hampshire gardens
The gigantic blue mopheads or lacecaps known as bigleaf hydrangeas (Hydrangea macrophylla), which are familiar to most gardeners, form their flower heads at the tips of stems on old wood from the previous year. Although lower buds along the stem have the capacity to grow blooms as well, the hydrangea’s blossoming potential is decreased if those buds are died or damaged throughout the winter. Wait until new growth sprouts in the spring before pruning your bigleaf hydrangeas. Approximately 1/4 inch above the first group of live buds, prune the plant. A hint: the interior of living stems will be green, whereas the interior of dead stems will be brown. Cut completely dead stems flush with the base.
The three other hydrangea species that are frequently planted in Fresh Hampshire—oakleaf (H. quercifolia), panicle (H. paniculata), and smooth—all bloom on new growth. Before the emergence of the leaves in the late winter and early spring, remove wasted flowers and prune the plant to improve its general structure and habit.
In conclusion, there are a ton of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.
