One of the best ways to encourage your hibiscus plants to produce more and larger flowers is to deadhead them. If you’re new to gardening, you’re probably wondering why you would take your plant to a hippie music festival.
For seasoned gardeners, this is likely to be something you stop and do whenever you see a plant with spent blooms. I’m guilty of deadheading all the marigolds outside the front office at my children’s school. Some of the office ladies probably wonder what that crazy mom is doing in the flowerbed, but I’ll tell you what, those marigolds have never looked better!
Chopping off flowers can actually make your plant bloom like never before. Here is everything you need to know about deadheading hibiscus plants!
Growing up in South Florida, my family had a long hibiscus hedge along one side of our house. The flowers were large and red, with a generous helping of pollen that would commonly hitch a ride on the sleeve of my t-shirts. They were always aflutter with butterflies and bees and were one of the loveliest things in the garden.
The flowers at my childhood home were a tropical variety, and if you live in zones 9-11, you’re lucky to grow these stunning hibiscus in the ground. North of zone 9, tropical varieties make striking container plants that must be brought indoors for the winter. There are also plenty of varieties of cold hardy hibiscuses that will live as deciduous shrubs in zones 4-9.
Hibiscus plants are primarily summer-blooming plants. Some bloom for 2-3 weeks, while others can flower for 2-3 months. Some tropical varieties bloom nearly year-round, only taking a break when the temperature falls below 50°. The foliage is lovely, ranging from deep, glossy green to shades of burgundy and deep purple.
The main attraction of hibiscus plants, of course, is the flowers. The gorgeous flowers come in a range of colors, including red, blue, pink, yellow, orange, white, and purple, and plenty of multicolored varieties. The flowers range from a respectable 3” in diameter to a remarkable dinner plate size (12”). They boast some of the largest of all perennial flowering plants.
Hibiscus plants are known for their large, colorful flowers that can bloom throughout the summer months. While deadheading spent blooms is an important garden task for many flowering plants you may be wondering – do you need to deadhead hibiscus?
The simple answer is no, deadheading is not required for hibiscuses. However regularly removing spent blooms can maximize the flowering potential of these gorgeous plants.
What is Deadheading?
Deadheading refers to the practice of removing faded or dying flowers from plants. Gardeners deadhead for both practical and aesthetic reasons.
On the practical side, deadheading prevents plants from going to seed. When flowers finish blooming, they begin producing seeds which can sap energy from the plant. Deadheading interrupts this process, allowing the plant to focus its energy on new blooms instead of forming seeds.
Aesthetically, deadheading makes plants look tidier and healthier. Wilted blooms aren’t much to look at, so getting rid of them improves the appearance of the garden.
Do Hibiscuses Need Deadheading?
Most hibiscus varieties do not require deadheading. The large, showy blooms tend to fall off the plant naturally once they fade. This characteristic makes hibiscuses essentially “self-cleaning”.
However, even though it’s not mandatory, deadheading hibiscus regularly can provide benefits:
-
More flowers: Removing spent blooms signals the plant to produce new buds, resulting in more flowers over the season.
-
Bigger blooms: With faded flowers out of the way, remaining buds get more energy and room to reach their maximum size.
-
Longer bloom time: Deadheading encourages hibiscuses to bloom over a longer period, starting earlier and continuing later into fall.
-
Neater appearance: Getting rid of droopy, browning flowers keeps hibiscus plants looking their best.
When to Deadhead Hibiscus
Timing is important when deadheading hibiscus. These tips will help maximize the benefits:
- Deadhead blooms as soon as they fade or wilt. Don’t leave them on too long.
-Aim to deadhead every 2-3 days during peak flowering. Frequent deadheading keeps plants looking their best.
-Slow down deadheading as blooms decrease later in fall. Allowing some flowers to go to seed won’t harm the plant.
-Stop deadheading altogether after the first fall frost. Energy should go to the roots, not new blooms.
-Resist deadheading during winter dormancy. It can stimulate growth susceptible to cold damage.
How to Deadhead Hibiscus
Luckily, deadheading hibiscus is quick and easy:
-
Hand pinch off individual blooms. Stems are tender so flowers pluck off cleanly.
-
For thicker stems, use pruners or scissors to snip the flower stem near the base.
-
Avoid cutting into thick branches, only remove the flower stem.
-
Be gentle around buds, don’t damage unopened blooms nearby.
-
Clean tools between plants to prevent transmitting diseases.
-
Remove deadheaded debris from the area to improve appearance.
Tips for the Best Bloom
Beyond deadheading, here are some additional tips for maximizing hibiscus flowers:
-
Plant in full sun (at least 6 hours daily) for the most prolific flowering.
-
Give hibiscuses plenty of space between other plants for good airflow.
-
Water thoroughly when top few inches of soil become dry. Don’t let hibiscus wilt.
-
Fertilize monthly during growth and flowering with a balanced flower fertilizer.
-
Prune lightly in late summer to encourage new growth and possible rebloom.
Varieties That Don’t Require Deadheading
While most hibiscus benefit from deadheading, some varieties are exceptions:
-
Rose mallow (Hibiscus moscheutos) has a naturally shorter bloom time, so deadheading provides little advantage. Enjoy its flowers as they come and go.
-
Hardy hibiscus varieties are less responsive to deadheading. Focus efforts on late-blooming tropical varieties instead.
-
‘Roselle’ hibiscus produces edible fruit used in jams and teas. Avoid deadheading this one to allow ample fruit production.
The Bottom Line
To sum it up, deadheading isn’t absolutely necessary for hibiscuses, but doing it regularly encourages more prolific flowering and visually appealing plants. It’s a simple gardening task that pays off if you can make it part of your routine. Pay close attention to bloom stage, and be consistent during peak flowering. Remove spent blooms by pinching or snipping, being careful of tender new buds.
Keep these deadheading tips in mind as you care for hibiscuses this season, and your reward will be fabulous flowers all summer long. Enjoy the process and the beautiful results!
Pinching Off Hibiscus Blooms
Deadheading, the process of removing fading flowers, can improve the appearance of the plant and prevent reseeding. According to information about hibiscus flowers, deadheading hibiscus is not a necessary part of hibiscus flower care. This is true for tropical hibiscus flowers, for rose of Sharon and for other types of hibiscus family blooms. If youre pinching off hibiscus blooms, you may be wasting time and actually preventing a late show of hibiscus flowers. You may also be delaying next years flowers. Information on this subject indicates you may be inhibiting additional blooms later in the season, as these flowers are actually considered to be self-cleaning, dropping off on their own and replaced with new buds.
About Deadheading & Why it’s Important
Deadheading is simply the removal of spent blooms from a flowering plant. Some flowers can be snapped off the stem with a quick finger pinch, while other, larger plants with woodier stems may require a pair of hand shears to carry out the task. I like to use shears because some plants have longer flower stems and can look unsightly with all the flower heads picked off.
The reason for deadheading is uncomplicated. Deadheading makes more plants produce a greater number of blooms. In most cases, this is because the plant can redirect energy and nutrients away from the dying flowers and into building new flowers and helping them bloom.
Most hibiscus plants develop multiple buds at the end of each stem. The flowers typically bloom for 1 day, with some varieties blooming for 2-3 days. Keeping these plants deadheaded does 3 positive things for the successive buds:
First, it redirects energy to the newer flowers, as I mentioned. For hibiscus, there is an additional benefit to deadheading. Since the buds tend to form in clusters and have large blooms, removing the spent flowers allows more sun exposure to reach the younger buds.
Another reason for deadheading is simply for aesthetic purposes. A plant covered in drooping, dead flowers just lacks appeal. Deadheading gives plants a cleaner, healthier appearance overall.
Finally, deadheading prevents flowers from going to seed. Most flowers produce seeds. For some plants, these seeds are encased in a delicious casing (all fruits are seed bearers). If a flower is pollinated, the plant will produce seeds that fall from the plant when the flower dies. This is how plants reseed themselves, which can lead to a lot of digging.
The ‘Roselle’ variety produces delicious fruits, often called Jamaican Sorrel. These fruits are excellent for making teas, jams, and other sweet treats. If you have this variety, then skip deadheading altogether. Harvest delicious fruits instead!

Should I Deadhead Hibiscus?
More info on the subject of, “Should I be deadheading hibiscus?” indicates it is okay to remove the blooms if they are sickly or if you don’t need the plant to bloom later in the season. Since most gardeners can’t imagine not wanting more hibiscus flowers, however, we should probably stop deadheading hibiscus plants.

Why does my Hibiscus not produce new flowers after deadheading?
One of the biggest reasons your hibiscus might fail to produce new blooms after deadheading is that the whole point of flowers is to reproduce, and the seed pods are proof that that task is being fulfilled. By removing the seed pods, the plant knows it hasn’t yet achieved its goal and will produce more buds to try and reproduce.
How often should Hibiscus blooms be deadheaded?
Deadheading tropical hibiscus blooms – Hibiscus rosa – sinensis – is best done every 3 to 5 days. Many hibiscus blooms will open and fade within 1 to 2 days, so regular deadheading during the growing season is a task to keep on top of.
Do hibiscus plants need to be cleaned?
The biggest argument is that it doesn’t guarantee new blooms and may even shock the plant into pausing the production of fresh flowers if you get too aggressive. Hibiscus plants are usually self-cleaners, meaning they’ll drop spent flowers independently. Another widespread argument is the time investment.
How do you take care of a hibiscus plant?
Just be careful only to cut the small portion of the stem necessary to remove that flower. Use clean, sharp shears to prevent transmitting any potential pests or diseases from other plants. Give the entire plant a slight trim when the blooms are thinning out. Hibiscus plants bloom on new wood, and they develop buds quickly.
