MINNEAPOLIS, October 7, 2019 (WCCO). WCCO viewers are witnessing flowers that don’t often blossom in the fall, despite the fact that it is autumn.
Jodie brought in a picture of lilacs blooming in New Prague, and Bill put in a picture of them in Circle Pines. Therefore, people are curious as to why plants are flowering in October. A good query.
Julie Ackerman noticed one of her lilac shrubs outside of her Circle Pines house was in bloom about a week ago.
Ackerman remarked, “It was the first time we had come here in 18 years. “I guessed they might have believed it to be spring once more.
Julie Weisenhorn, an associate extension professor in the University of Minnesota’s Department of Horticulture, received the image from WCCO. Although some lilac bushes do bloom again in the late summer, she claimed that these blooms are more likely the result of Minnesota’s recent weather patterns.
Weisenhorn claimed that the varying temperature was what caused the plants to bloom. “We’ve had higher temperatures, but we’ve also had cool temps.
She claimed to have observed azaleas blooming in the fall, but not lilacs. The plants that blossom in the spring establish their buds a few weeks after the flowering period. Typically, the weather causes them to bloom a year later.
According to Weisenhorn, it is actually a hormonal reaction to the temperature and light of the environment. Weisenhorn speculates that the blooms may have mistaken the fall for spring due to the cooler late summer and warmer September.
Ackerman questioned whether a recent treatment for the lawn could have caused the fall blossoms. Theresa Rooney, a Hennepin County Extension Master Gardener, contends that this is most likely not the case.
“The environmental stress is more likely,” Rooney added. Rooney said that since every plant is unique, it makes sense that only one plant in a row of several might blossom. Some people are weaker or more stressed than others.
Weisenhorn said there’s a chance more plants could grow in the area as Minnesota’s weather patterns continue to shift.
She said, “We could.
Since so many variables are shifting and fluctuating, we can’t say for sure. However, she advises people not to be alarmed if their lilacs bloom in the autumn. The plant will be fine even if they most likely won’t rebloom that spring.

A lilac can bloom in September, right?
SANTA PETRA
When Minnesotans head outside to take in the Fall oranges, yellows, and reds this week, they might be startled to find delicate purple hues mingling with them.
“According to Fred Struck, owner of Traverse des Sioux Garden Center in St. Peter, lilacs occasionally rebloom in September.
He stated that when something in nature prompts lilacs to emerge from hibernation, it does occur in our climate.
This year’s temperature and moisture levels deceived the plants into believing they experienced a brief period of winter.
On the breezes of this fall, the pleasant scent that permeates the air in the spring is hardly noticeable. Lilac branches with blooms are few and few between, and late bloomers have smaller flowers than those from spring buds.
Struck offered the following advise to owners of common lilac shrubs that are blooming this fall: “Embrace them. There is also no cause for concern. In the spring, they will bloom once more.
For at least one type, the Boomerang, bunches of fragrant lilacs are to be anticipated at this time of year, according to University of Minnesota Extension educator Shane Bugeja. The 2009-original reblooming hybrid blooms flowers intermittently over the course of many months.
This year’s growing season was stressful for the common lilac kinds that Minnesotans generally employ as garden hedges, according to Bugeja. This summer, numerous inquiries to his Mankato office came from locals who were alarmed that the leaves on their lilac plants were turning dark or dropping off.
“This year, there was a severe fungus outbreak that affected a large portion of Minnesota. The lilac bushes were not killed, but they were stressed. Stressed plants can bloom at strange times of the year.
He advised property owners with aged lilac hedges to think about removing stressed plants’ limbs.
“Pruning your lilacs in late February or early March is appropriate if you don’t care if they bloom next season.
When a lilac blooms in the fall, what does that mean?
Q. I recently saw a photo of a lilac that was allegedly in bloom this fall on the news. Is it still feasible for lilacs to bloom at this time of year?
A. It is feasible, yes. Occasionally, after a challenging summer is followed by milder weather, spring-flowering trees and shrubs will show one or two flowers. Before their typical spring bloom time, these plants set their flower buds in the summer. Some flower buds may emerge in the fall if the weather is unusual or harsh. The plants won’t suffer, they’ll just have a few fewer spring blossoms. I came across a Callery pear in full bloom in October of one year. The following year, I came back to discover the plant fully leafed out.
A branch from my rose bush was recently broken off by someone. In light of the impending winter, should I take any precautions to protect the plant?
A. Pull out the bypass pruners, which have two razor-sharp blades. Make a cut immediately above a leaf or the spot where a leaf was formerly linked to the surviving stem below the point where the branch broke. Clean cuts heal more rapidly and lessen the possibility of pests and pathogens getting inside the plant. Check the area where the branch was once linked to the plant if they completely broke it off. Remove only the loose bark. Avoid cutting into the stem and rubbing pruning paint on it. Once we have a week or longer of subfreezing temps, give your regular winter care.
A Christmas cactus I own is about to blossom. Can I split it up because it’s getting too big?
A. Take pleasure in the blossoms and refrain from pruning or dividing the plant until late spring, when it will transition to active growth. To promote more compact development, it is safest to trim back the longer branches. Use a sharp knife to cut off a handful of the portions from each stem. These pieces can be rooted to create new plants. You can divide plants that are growing in a single pot. But be aware that your plant’s health will likely suffer as a result of this great stress. Wait until the plants are actively growing and after flowering if you desire to divide the individual plants. Plants should be divided with care and replanted in a similar potting soil. Put each plant in a drainage-holed container that is just a bit bigger than the remaining rootball.
What truly eliminates creeping Charlie in the grass? I’ve tried a lot of different products, all to no avail.
A. It is important to address this query once more because it is typical. If you and your neighbors don’t like the flowers and aroma this hardy groundcover offers, there is a control alternative. The University of Wisconsin-Madison discovered that timing was the key to taming this plant. When the creeping Charlie is fully bloomed or following a hard freeze, spray a broadleaf weedkiller designed for use in lawns. Remember that when the existing plants are killed, there remain numerous seeds in the ground that will sprout and thrive. It will take several years to completely eradicate this weed. Spot treating will help you use fewer chemicals. Effective weed killers with dicamba and banvel are damaging on trees and shrubs.
Do lilac trees have two blooming seasons?
Compared to other lilac trees, bloomerang lilac trees are more compact, reaching a short height of 4-6 feet tall and a spread of 4-6 feet, giving them a pleasing, rounded appearance. Their long, arched branches bear their veined leaves, which are bright green for the majority of the year until turning yellow in the fall.
The characteristic 4-petaled, 4-6 inch deep lilac-purple blooms on bloomerang lilac trees appear starting in May, cease blooming in June, and then return in July through the first frost of the year.
Specifications
With tall, arched branches, a compact and rounded shape, and rich green foliage that turn golden in the fall. Four spread petals, 4-6 inch, lilac-purple flowers that bloom in the spring and later in the summer.
If so, do they blossom in October?
Many enquiring people have contacted us to enquire why the lilacs close to the middle school are flowering right now.
After all, in Minnesota, lilacs bloom in May, not October! So what is happening here?
The lilac shrubs went into an early dormancy to help the plant protect itself from the extreme heat and dryness of this summer. The plant is prepared to resume operations now that it has cooled off and we’ve had some decent rainfall. This plant was misled into believing it was ready to blossom by this condition-forced dormancy, similar to how lilacs bloom in the spring after a long winter slumber.
Although the plant won’t be harmed by this October bloom in and of itself, it may become less likely to produce robust, vigorous, or abundant blooms in the anticipated springtime.
What color is a lilac shrub in the fall?
The dwarf Korean lilac bush will reach a height of 4 to 5 feet (1.5 meters), which is smaller than that of other lilac varieties. These kinds of “Small gardens benefit from having a petite lilac bush.
The miniature lilac blooms for about two weeks in late spring or early summer, like other lilacs do. The flowers are clusters of tiny, light-pink petals that have a lovely scent. The leaves’ rusty-brown color in the fall might offer some “adding fall hues to your garden.
When do lilac bushes need to be pruned?
All lilacs should generally be clipped right away in the spring after they have finished blooming. Lilacs set their flower buds for the following year immediately after the current year’s flowers have faded, therefore trimming later in the summer or fall will result in the removal of most or all of the blossoms for the following year. The larger common lilacs as well as the shorter or more “shrub like” cultivars are all subject to this timing guideline. While the “when” of lilac trimming is rather simple, the “how” is a little more difficult. For the time being, we’ll refer to lilac pruning as either maintenance pruning or rejuvenation pruning to keep things simple.
What causes lilacs to bloom again?
We received a text message from a listener in area code 651 asking, “What would cause lilacs to bloom in September?”
When mild fall weather arrives following a cool down or after a strenuous summer, lilacs and other spring blooming plants may occasionally be persuaded to rebloom.
There may be fewer blossoms the next spring if you do have fall blooms.
Are there lilacs that bloom late?
True to its name, the shrub lilac that blooms latest is the Late-blooming Lilac. Late May to early June sees the blooming of large clusters of fragrant, light purple blooms. Fall causes the deep green foliage to become golden-yellow. For our environment, the late-blooming lilac is a very robust and adaptable shrub that, once established, can survive a wide range of soil conditions (with the exception of rainy places). It is a pretty shrub that works well as a specimen or as part of a substantial border.
How old are lilac bushes?
Lilacs are renowned for their longevity and hardiness.
Numerous lilac shrubs reach ages of greater than 100. They frequently outlive the residence of the gardener who planted them due to their extended lifespan. As a result, if you’re driving along a country road and come across a few what appear to be random lilac bushes, it was probably a farm or house a century ago.
Try growing lilacs in your garden if you haven’t already. They not only return every year, but they also put on a display for the senses with vibrant blossoms and enticing scents. Lilacs have a lot to offer, and learning about their history demonstrates just how unique these plants are.
Do you need to remove wilted lilac blooms?
Your lilac bush will produce more blossoms the following year if you remove the dead flowers. When cutting off your flowers, it’s crucial to only remove the wasted blooms—don’t worry about any nearby stalks. Simply concentrate on the spent bloom’s stem if you can see the two fresh shoots that will grow into blooms the following year. Avoid cutting off the blossoms for the following year!
I now wish to stimulate a second flowering on my dwarf Bloomerang, which ought to happen in late summer or early fall. In order to produce more new growth and blooms during the second bloom season, the spent spring blossoms should be pruned off. A small amount of fertilizer made specifically for woody plants, which I could also use, will help encourage the shrub to bloom once more.
Should lilacs be deadheaded?
Dwarf lilacs that resemble ordinary lilacs include the “Palibin” Meyer lilac (Syringa meyeri “Palibin”) and the “Miss Kim” Manchurian lilac (Syringa pubescens ssp. patula “Miss Kim”). However, they hardly ever need pruning for maintenance, though you can do it sometimes for shape. They can also profit from deadheading, just like other lilac kinds.
The act of manually removing withered blossoms from a plant is known as deadheading. This encourages some plants to continue blooming. But only during the first several years of growth does deadheading seem to make lilacs bloom more effectively.
Within two to five years, young lilac plants should start blooming. Deadheading the spent blooms when the plants are young encourages the plant to focus its energy on developing new buds. It won’t require this stimulation once the plant has grown older, and you’ll probably have so many flowers that the task would take too long.
Your lilac will blossom beautifully some years, and less so other years, just like with any plant. Blooms frequently rely on the climate. You will be rewarded with an abundance of blossoms the next year if you have a beautiful summer during which strong new growth emerges. Less flowers will bloom in a summer with harsh weather. Therefore, if your lilac’s color changes from one year to the next, don’t get alarmed. The blossoms will come as long as the plant is strong and you continue with maintenance pruning.
When does the lilac flower bloom?
The “Excel” cultivar blooms earlier than most lilac kinds, which typically bloom in the middle of spring, around May. To lengthen the flowering season from late winter to late spring, or two nearly continuous flushes of blossoms, combine this early-blooming lilac with other, later-blooming types.
