Cutting off the tops of stems that have grown out of control is frequently insufficient when pruning lilacs. It is typically preferable to remove the entire stem. The best way to trim lilacs is with clippers. To avoid spreading and promote later blooms, remove spent blossoms right down to the stems. Three-quarters of the branches should be pruned. Remove any shoots that are emerging from the main trunk and are growing close to the ground. Lilacs within the inner branches may need to be trimmed in order to increase air flow or let more light through.
However, it may be essential to prune the entire bush or tree to approximately 6 or 8 inches (15-20 cm) above the ground if lilac shrubs are already too big or starting to look unpleasant. Remember that it takes around three years for flowers to grow after the entire bush has been removed, so you might have to wait.
When should lilac blossoms be cut?
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.
Do you need to remove dead lilac flowers?
The removal of spent flowers to encourage new blooming—deadheading—is a crucial part of lilac maintenance. Lilacs should be deadheaded as soon as the flowering is finished to allow the plants to grow robust, healthy buds that will flower vivaciously the following year. According to the University of Minnesota Extension, you can use a hand pruner, but larger plants could require a hedge trimmer. Only the dead blossom should be removed; the plant should still have two leaves.
According to the Chicago Botanic Garden, you should prune lilacs at the same time as you deadhead them since they set the blossoms for the following year quickly after flowering. By doing this, you can prevent damaging or removing the developing buds. Three to four years after planting, you should start pruning lilacs. It might be necessary to trim back overgrown lilacs to just a few inches above the ground. Winter is the ideal time to complete this. In this instance, it will take the shrub one or two growing seasons to start blooming once more.
Are lilac flowers cuttable for vases?
Early in the morning, when the lilac blossoms are fully hydrated, is the ideal time to cut them. Use clean, precise pruning shears to trim the stems, and then immediately submerge the cut stems in a pail of water. For the longest vase life, cut lengthy stems. Prepare a vase for the flowers inside.
How are lilac blossoms harvested?
Lilacs perfectly evoke the feeling of spring. Because of their distinctive aroma, they were utilized in colonial décor to help spruce up the house after a long winter! I usually reply zinnias are my favorite flower, but I’m starting to change and say whatever is in bloom when I’m asked what my favorite flower is. My current obsession is lilacs, and peonies will soon follow.
Cut lilacs make a lovely gift for Mother’s Day or a lovely accent to your brunch table at your family gathering. Before the brief season is up, I’m looking forward to bringing bunches of lilacs to the farmer’s market over the coming few weeks. To show you how we gather lilacs, Kyle and I put together a little film. Hope you enjoy it! We’ve never shared videos on Under a Tin Roof before, but we plan to do so in the future.

step one:
Lilacs are finest trimmed in the early morning or late evening, before the sun has drained much of their water. It’s not a good idea to cut them on a bright afternoon because they tend to wilt quickly. If I cut on a cloudy day, I’ve discovered that they perform best in the late afternoon.
Look for stems that have at least a third of their blossoms open. If all of the blooms are still closed when clipped, they could not bloom. The flowers won’t stay in the vase as long if they are all opened. Cut to the length you want. Always cut a little longer than you need them so you may trim the ends again to give the stems some new life.
step two:
Most lilacs have a single main stalk that branches off into several blossoms. Since the shorter one-year growths are frequently too short for a vase, I prefer to retain them attached to the bigger main stem. Snip any branches that have reached their ends if there are any. Remove any leaves from the branch because they will get water from the stem and then become wet. Only the foliage that will be retained above water should be left on the stem, if any.
step three:
You should trim the very bottom of the stem in half or quarters after removing the leaves and extra branches. This can be a bit perplexing because the majority of sources say to “cut an X at the bottom,” but what does that actually mean? Simply cut the stalk in half or more at the bottom and slightly tear the ends up. Lilac branches don’t absorb water from a vase very well because they are so thick. Giving them a deeper cut at the bottom enables them to take in water more quickly and avoid wilting. This is the critical action!
Make a second cut to the stem higher up the following day, and then cut the bottom again in half. Your lilacs will last in the vase for 5–10 days if you do this every day or every other day.
step four:
The lilacs should be placed in water right away after being cut and the leaves stripped. Sincerely, I don’t give our flowers’ water temperature any thought, but other people do. I only use water that I pump myself! You are welcome to add a flower food to the water. Although adding some granulated sugar also works just as well, it does assist.
As soon as you can, start cutting your lilacs because they won’t be around much longer. Watch the video at the top of this post for more specific instructions on how to collect this lovely spring bloom. Do you share my passion for lilacs? In the coming days, I intend to create some lilac solid perfume to offer on this site!
How do you prevent cutting lilacs from wilting?

Cut them in the morning or evening.
This enables them to contain the most water possible. They are far more likely to become dehydrated from the warm sun if you cut them at noon.
Cut them with sharp pruning shears.
Never try to cut them with a standard pair of scissors! To ensure a clean cut, use (or pick up) a pair of pruning shears.
To give the lilacs greater surface area to absorb water, cut them at a 45-degree angle.
When you go to cut the lilacs, bring a pail of chilly water with you into the garden. Put the stem in the water as soon as you cut it to prevent it from becoming dehydrated.
Remove excess leaves.
Removing excess leaves is beneficial for two reasons. Make sure to first remove any leaves from the vase you intend to use that would otherwise be submerged in the water. That will prevent your water from turning bad.
Second, some branches have a lot of extra leaves on them depending on the branch you cut. Just bear in mind that any leaves you keep will reduce the amount of water needed to keep your cut lilacs alive. I like to leave some leaves on for some extra green.
Get your vase ready!
Make sure your vase is tidy and big enough to hold your cut lilac flowers. Be careful since bases that are thin run the risk of falling over.
Fill it with flower food and warm water. Personally, I think it’s a great idea to get some flower food to keep on hand if you enjoy having fresh flowers in your home!
If you don’t have flower food, you can add a teaspoon of sugar, a teaspoon of white vinegar, or a teaspoon of bleach to the water along with a sugary citrus soft drink to help manage bacteria. Other professionals advise using crushed aspirin instead of flower food to keep the water clean.
To prevent them from drying out and wilting too rapidly, keep your lilacs away of direct sunshine.
Split the bottom of the stems.
Split the bottom of the stems of your lilacs before placing them in the vase that you’re using. To do this, you can either use a hammer on the bottom (I suggest doing this outside to avoid damaging your table!). or create an x at the bottom with your shears.
This will make it possible for the stems to absorb more water, preventing your lilacs from wilting too soon.
What are lilac flowers used for?
1. Make them sweet for dessert. Lilacs are edible, so feel free to use them as a garnish on your sweets. Lilacs can be sprayed with a little water and then covered in granulated sugar after being newly harvested and thoroughly cleaned.
Top cakes, cookies, cupcakes, and other delicacies with them. And if you adhere to the aforementioned rules, they are absolutely delicious!
2. Make ice cubes out of them. Consider putting lilac blossoms in ice cubes if you are holding a baby or bridal shower. This will add taste to the ice tea or lemonade you are serving as well as some color to the cubes.
It’s incredibly lovely and adds a great touch, giving the impression that you have too much free time.
For even more color, combine them with pansies!
Have you seen my raspberry and mint-infused ice cubes? The recipe is located here!
3. Produce your own lavender honey.
Honey and lilacs make a lovely combination. You only need fresh lilacs and your preferred type of honey to produce your own lilac honey.
I adore using a brand like this one that is organic. Place the stems in the honey jar, cover it, and store it somewhere dry and cool for 4 weeks to infuse. This lilac honey tastes delicious on muffins, toast, and other baked goods.
Are male and female flowers required for lilacs?
Abiotic and biotic methods are both used to pollinate lilacs. When a pollen sac travels from the stamen to the pistil with the help of an active pollinator, such as a bee, butterfly, or bird, this process is called biotic pollination. Abiotic transportation is made possible by the wind, the rain, or other natural occurrences. A pollen tube develops when the pollen sac touches the stigma of a female flower. The tube enters the ovary through the style. When a lilac plant has both male and female flowers, it can self-pollinate. It can also be cross-pollinated if there is another lilac bush nearby, which occurs when a pollen sac from one plant lands on the stigma of a flower from another plant.
After they bloom, how should lilacs be cared for?
Lilacs with good form require annual pruning to maintain the rounded shape that most gardeners like. For the purpose of regulating the shrub’s total height, pruning is also crucial. These robust growers can grow up to and over 20 feet tall, depending on the variety. A tall lilac’s flowers will also blossom close to the top of the plant, out of reach and possibly beyond where they can be easily seen and appreciated because the majority of the buds develop on the tips of the branches.
- Pay close attention. This spring, as your plants blossom, pay particular attention to the shrub’s shape. Note where the plant has the most of its flowers as well. Lilacs bloom toward the tips of their branches; the sunniest spots will have the largest and most vibrant flowers.
- Selectively prune. Selective pruning should be done after the blooms have faded and died to manage height and restore shape. Lilacs typically only need to be deadheaded and a few choice branches removed to enhance the form and look of the plant. It’s vital to only prune the limbs and branches required to maintain a properly shaped and proportionate shrub because they flower on the older stems.
- Cut those suckers off. Each year, healthy lilacs send up new suckers from the ground. Cut back some of the suckers and get rid of any twisted or lanky branches.
- Cut back by a third. The inside of the plant may get crowded with a tangle of older limbs over time and as it ages. Lilacs will consistently bloom for years with no maintenance, but some elderly plants may start to produce less. Cut back the chosen shoots and branches at ground level to eliminate around one-third of the plant each year in order to revitalize an older plant and promote more flowers.
Does pruning encourage or delay a lilac’s growth?
Although harsh pruning promotes new growth, because lilacs only bloom on old wood, it may take the plant several years to recover from a severe pruning before it can bloom effectively once more.
