Would you consider that to be an indicator if someone showed you a picture of a lilac flowering later this fall when we were having coffee at Garrison Keillor’s Chatterbox Caf?
Days have been quite enjoyable. We experienced a fatal frost a month late, and since then, the weather has been largely pleasant. What about peculiar plant behaviors? How about the lilac that is blooming?
Heirloom lilacs in bloom are a sign of spring. Lilacs are chosen by botanists across the United States for phenology studies of plant reaction to seasonal changes because their responses are such a reliable signal.
Jay Gurney, a nurseryman who will mark his 40th anniversary at Yankton Nurseries in 2017, keeps an eye out for signs in the weather and the growth of the plants.
Proven Winners’ “Bloomerang” Lilacs are reblooming lilacs that appear in August or September. Or, occasionally, a Dwarf Korean lilac will bloom later, according to Gurney. He questions whether the flowering lilac in the shot is the traditional variety.
“Until a hard frost, roses are in blossom. There are times when a viburnum’s tip blooms late. Is this a lilac growing in an odd place, like up by the house? As is typical for this time of year, he has lilacs that have mostly lost their leaves. He hasn’t heard any other remarks about the lilacs blossoming lately, and he receives lots of inquiries from others in the neighborhood. He would want to see a plant in such bloom.
Here at the Chatterbox, we are savoring the unusually warm weather. As we ask for more coffee, there is a nagging insinuation that there will be some “Hell” to pay for our good fortune. Therefore, we press Gurney for details. How would the pleasant weather affect plants?
He stated, “In general, it doesn’t damage them at all; they aren’t being punished by harsh weather.
But he added, “In the early 1990s, we experienced the ‘Halloween blizzard. Like now, the weather was pleasant and dry. Then we received around two inches of rain right before Halloween. It became a blizzard on the backside. really cold Plants struggled because they didn’t have time to become more resilient. Plants struggle when the weather changes suddenly.
But as the days grow shorter, I’m now observing naturally falling tree leaves. I don’t see any new trees forming. Willows generally mature later and occasionally their wood doesn’t freeze as quickly for cold temperatures. However, this year we are seeing cool evenings with some light frost, 50 to 60 degree F. days, and nights.
This Rudbekia, often known as a Black-Eyed Susan, got out of its pot and is now flowering in the ground next to one of Jay Gurney’s greenhouses. Because the soil temperature in pots is lower than that in the ground, the perennial rudbekia plants surrounding this November blooming plant are dormant. Plants may signal hibernation by reducing their day length and lowering their soil temperatures. In later November, Gurney’s potted roses are still sporting foliage and blossoms.
Around the middle of December, the ground typically freezes. USDA Zone 5 had a good winter last year, and several plants from Zone 6 survived. Gladiolas and cannas that he unintentionally left in the ground last winter flourished this summer. Almost no ground froze, yet it didn’t appear to harm plants. Nothing has a chance as long as we don’t get a major blizzard that comes quickly!
This fall, I haven’t yet noticed a lot of geese. Cold weather is coming as soon as you notice them traveling south. Day length and soil temperature interact. There have been trees on Earth for millions of years. Gurney claimed that they know what to do. However, some people simply want to take advantage of the abnormally mild weather.
Before putting the hose away, Gurney suggested that you soak the yard. Lawn, trees, bushes, and perennials are all mentioned. ” You cannot hydrate frozen ground if it remains dry for the ensuing six months. Up until the ground freezes, plant a tree or shrub and water it in. They are then prepared to grow in the spring. Distribute organic fertilizer, such as dried dung or compost. Weeds that are actively growing can be eliminated. Kale, cabbage, and broccoli are being harvested in the late season by Gurney.
Fox Run Golf Course is open to enjoy the turf until daytime temperatures fall below 40 degrees Fahrenheit or it snows for additional plant-related possibilities in mild fall weather. The trails of Lewis & Clark Recreation Area are ready for bicycling, walking, and picnics, and the campgrounds is mostly available to see the change in tree and native grass color. Yankton may be seen from among the cottonwood trees from the open Meridian Bridge. A completely unrestricted gift is warm weather!

If so, do they blossom in September?
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.
Is it normal for my lilacs to bloom again in September?
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.

When is the lilac season?
Did you know that the National Gardening Bureau has designated 2022 as the “Year of the Lilac”? They have a sweet, eerie aroma and are among the easiest shrubs for your landscaping to maintain that bloom in the spring. Find out how to plant, nurture, and prune your lilacs.
About Lilacs
Syringa vulgaris, or common lilac, is prized for its tenacity, dependability, and scent. Lilacs are so hardy that they can live for more than 100 years and frequently outlive the houses they were planted near.
This tiny, multi-stemmed deciduous shrub (or tree) has approximately ten canes and blooms at eye level. The height of a common lilac can range from 8 to 12 feet, depending on the cultivar. The aromatic flowers attract butterflies and make good cuttings.
There are lilac types that come in white, cream, and even pink and yellow, though the blooms are typically lilac/purple in hue (ranging from very pale to extremely dark). Flowers can be solitary or double in number.
Lilacs bloom in northern states from mid- to late spring for around two weeks. However, there are lilac varieties for early, mid, and late seasons that, when cultivated together, guarantee a consistent bloom for at least six weeks.
Lilacs do best in soil that is fertile, humus-rich, well-drained, and neutral to alkaline (at a pH near 7.0). Add compost to your soil to improve it if it is in bad condition. (Learn more about adding amendments to the soil and getting it ready for planting.) Lilacs don’t enjoy having their feet wet and won’t blossom if they are kept too moist, so make sure the planting area drains well.
Lilacs should be planted in full sun, which is defined as having at least six hours of sunlight each day, for the finest blooms.
How to Plant Lilacs
- If you’re fortunate, a friend may offer you a sucker, or offshoot, of the plant’s root system. The sucker will first appear pitiful, but all you need to do is dig a hole, fill it with soil, and then insert the sucker. water next, and then wait. You’ll be rewarded with enormous, fragrant blossoms in 4 or 5 years.
- Lilacs purchased from nurseries can also be planted easily. If the plant was cultivated in a container, spread its roots out as you plant it; if it was balled or burlapped, gently remove the covering and any rope before doing so. Set the plant 2 to 3 inches deeper than it was while it was growing in the nursery and cover the roots with topsoil. in water Then add more topsoil to the hole to finish it.
- Depending on the kind, place multiple lilac bushes 5 to 15 feet apart.
- Apply a layer of compost under the plant each spring, followed by a layer of mulch to keep moisture in and weeds under control.
- If the weekly rainfall is less than 1 inch, water during the summer.
- If lilacs receive too much fertilizer, they won’t bloom. In the late winter, they can manage a few 10-10-10, but no more.
- Spread some lime and thoroughly composted manure around the base of your lilac bush once it has finished blooming. Remove suckers while you form the shrub by trimming it.
Pruning Lilacs
- Since lilacs blossom on old wood, it’s important to prune in the spring immediately following their bloom. You risk removing the wood if you prune later in the summer. A word of advice: It’s time to prune if your lilac flower clusters are getting smaller!
- After bloom each year, cut away any dead wood. Remove the oldest canes by pruning (down to the ground). Take out the tiny suckers. Reduce weak branches until a robust shoot remains. Reduce tall canes to eye level.
- Remove one-third of the oldest canes (down to the ground) in year one, half of the remaining old wood in year two, and the remainder in year three if your lilac is very old and in poor condition. Cutting the entire plant back to a height of approximately 6 or 8 inches is another option for elderly lilacs. Although it sounds dramatic, lilacs are remarkably resilient. This option’s drawback is that it takes some time for the hair to grow back. The lilac will grow back bursting with blooms, so there will be less work and more reward.
- It is important to understand that extreme trimming causes bloom loss for one to three years. For these reasons, a smart pruning program gives the bushes yearly attention in an effort to avoid making dramatic and severe cuts.
The Syringa vulgaris kind of lilacs is the most widely grown and fragrant:
- Try the double magneta variety “Charles Joly” for an early bloom.
- Lilacs in the middle of the season include “Monge,” a deep reddish purple, and “Firmament,” a delicate blue.
- Miss Canada, a reddish pink, and Donald Wyman, a solitary purple, are two late-season beauties.
Syringa x hyacinthiflora, an early-flowering lilac cultivar, opens 7 to 19 days before those of the common lilac. Hummingbirds and butterflies are attracted to its fragrant blossoms.
The cutleaf lilac, a fragrant pale lavender, is one of the common lilacs that may flourish as far south as Zone 9. Common lilacs appreciate cold weather. The beautiful shrub Syringa patula ‘Miss Kim’ has light lilac-blue flowers that eventually become white.
There are tiny kinds for gardeners who simply don’t have the space for the conventional larger lilacs, particularly those in urban settings. Even in a container on your balcony or patio, they will grow.
- ‘Baby Kim’ has a lovely rounded shape, only grows 2 to 3 feet high (and 3 feet wide), and has purple flowers that draw butterflies. Hardiness from Zones 3 to 8 extended.
- Compact lilac ‘Little Lady’ (Syringa x) has dark pink buds that open to lilac-pink flowers and grows to be 4 to 5 feet tall and wide at maturity. Zones 2 to 7 are tough.
- Syringa vulgaris cultivars “New Age Lavender” and “New Age White” were developed for mildew resistance and are quite compact, growing from 4 to 5 feet tall and wide. Hummingbirds and butterflies are drawn to their fragrant blossoms. Zone 4 hardy.
